Title: Improvements relating to the braking of motor vehicles
IPC: B60T13/74
Filed: 1935-05-17
Abstract: 460,180. Controlling motor vehicles. PEYRUQUEOU, P. May 17,1935, No. 14472. Convention date, May 17, 1934. [Class 79 (v)] [Also in Group XXXIV] In means for controlling motor vehicle brakes by the accelerator pedal, movement of this pedal R to the extent of angle A beyond the closed-throttle position is permitted by a telescopic device 3 in the connection to the throttle and during this movement a contact 1 carried by the pedal moves over contacts 2 of a rheostat whereby the brakes are gradually applied. As shown, the brakes are applied by a disc 8 connected to the brakes at 10, 11, adapted to engage a disc 7 driven from the vehicle drive shaft 4, the disc 8 being attracted to the disc 7 when a winding 9 in circuit with the rheostat is energized. The circuit is adapted to be broken by contacts on the gear lever to prevent application of the brakes during gear changes and also by contacts actuated by the ignition key to avoid waste of current when the vehicle is stopped. The Specification as open to inspection under Sect. 91 comprises also the following subjectmatter : The brake may be operated by a servomotor actuated by engine suction. The servomotor may be controlled by a slide valve connected by a friction coupling with the accelerator pedal so that the brake is applied whenever the pedal is moved in the throttleclosing direction and released by movement in the other direction. The servomotor, Fig. 3 (Cancelled), may have three stages or compartments, the pipes of which may be connected to pipes f, f<1>, f<11> of the graduator shown in Fig. 4 (Cancelled). This comprises a piston a subject to the suction through passage d and to springs e, e<1>, e<11> of different lengths which are successively engaged by the piston as the suction increases to connect the several compartments to suction. The braking action is thus graduated according to the extent to which the accelerator is raised and to the speed of the vehicle. An additional stopping device is provided for effecting complete stopping of the vehicle. As the braking action disappears at low speeds, an additional stopping device is provided for effecting complete stopping of the vehicle. The pedal of this device may be mechanically connected to the piston a to bring the servomotor, Fig. 3 (Cancelled), into action. The braking devices may be used in combination with transmission systems having a free-wheel, automatic declutching or a pre-selector gearbox. In the latter case, the braking action may be eliminated when declutching to effect the speed gear change. A suction servomotor for operating the brakes may be controlled electrically by a contact actuated by the accelerator pedal through a friction coupling. The brake servomotor may be operated by oilpressure furnished by the oil pump of the motor and controlled by a valve actuated by the accelerator pedal. This subject-matter does not appear in the Specification as accepted.

Filed: 1957-05-07
Abstract: 847,115. Stocking boxes. POMONA FOUNDRY Inc. May 7, 1957 [Dec. 4, 1956], No. 14527/57. Class 94(1). The box stacking machine described in Specification 765,887 is modified in that a single through conveyer carries boxes to the vertical stacking pathway and removes the completed stacks. Boxes are fed by gravity down a ramp 112 to a continuously running chain conveyer 94, the foremost box passing over a pivoted stop 20 which is raised by operation of switch means 205 by that box. In rising, the stop tilts the foremost box, which slides off it, and engages and stops the next box and those following. The foremost box touches a further pivoted stop 21 which incorporates switch means causing the elevator conveyer to raise it. At the limit of its travel, further switch means causes the stop 20 to be lowered to permit another box to advance. This continues until the desired number of boxes are in the vertical pathway, when all boxes but the last are lowered onto the latter (which had not been raised) and the stop 21 pivots clear to permit the stack to be carried out by the conveyer. The stack contacts switch means 225 restoring the stop 21 and initiating a further machine cycle. The infeed section of the conveyer may have box aligning bars 114 spring-biassed inwardly to position the boxes transversely prior to their being stacked. A safety switch may be positioned to stop the machine if the uppermost box in the vertical path is likely to contact the upper framework of the path. cardboard or other sheet material folded to produce a square base C having substantially triangular portions A, B extending from two adjacent sides. The protector may be used with articles secured by strapping &c.

Title: Improvements in the treatment of cellulosic materials
IPC: D06M11/61
Filed: 1966-04-01
Abstract: 1,141,016. Sheet forming. DEERING MILLIKEN RESEARCH CORP. 1 April, 1966 [9 April, 1965], No. 14628/66. Headings B5A and B5N. [Also in Division D1] Woven or knitted cellulosic fabrics are rendered amenable to deformation by treating them while in a relaxed state with liquid ammonia to render the cellulosic material amorphous as indicated by X-ray diffraction. The liquid ammonia is preferably maintained at -60‹ to -30‹ C. and treatment may be for from one second to five minutes, the treated fabric then being deformed into the desired shape if desired after drying under substantially water-free conditions, e.g. in a drying oven or at room temperature. The fabric may be made from cotton viscose rayon or paper yarn. The stability of the amorphous structure may be increased by dissolving a bond inhibitor in the liquid ammonia, suitable bond inhibitors being polyhydric alcohols containing 2-6 carbon atoms or mixtures thereof e.g. ethylene glycol, propylene glycol, glycerine, diethanolamine, triethanolamine, trimethylene glycol, tetramethylene glycol, butane triol, pentane triol, diethylene glycol, dipropylene glycol and triethylene glycol, and phenol formaldehyde, melamine formaldehyde or urea formaldehyde polymers; dimethyl ethylene urea, dihydroxy dimethylol ethylene urea, polyvinyl alcohol, polyethylene glycol. polyacrylic acid, polyvinyl acetate, the sodium salt of a styrene-maleic anhydride copolymer and end blocked isocyanate containing polymers. The treated fabrics may be laminated with vinyl films and moulded.

Title: Apparatus for transporting fruit
IPC: A23N4/14
Filed: 1968-03-27
Abstract: 1,224,202. Rotary conveyers. ATLAS PACIFIC ENG. CO. 27 March, 1968 [10 April, 1967], No. 14683/68. Heading B8A. Fruit with a double indent, e.g. apples, are fed on a conveyer 47 having means 51, for partially orientating each apple so that its indents are in vertical alignment and means 49, 96, 97 for disturbing unorientated fruit prior to the arrival of the fruit at a discharge station. The apples are picked up from a hopper 21 by a conveyer belt 23 and transferred to carriers 36 of a conveyer 10. A rotary member 44 transfers the apples to the conveyer 47 each carrier 46 of which has an apple orientating wheel 53 driven from a gear 131 pinion 93 and cable 86. As the apple is brought near to the point of transfer to a conveyer 151 carrying cooling and peeling mechanism (see Division A4) the wheel 52 is retracted (Fig. 7, not shown) by the action of a cam 82 and upper and lower pick-up fingers 153, 152, move downwards and upwards, respectively to engage the indents and precisely orientate the apple. If the apple is still so wrongly orientated in its carrier 46 that its indents are not in position to be entered by the fingers 152, 153 the latter displace the apple into a shoot 157 (Fig. 11, not shown) or this may be effected by a spring finger 156. The fingers 152, 153, rise together as they rotate with the conveyer 151 and so lift the apple out of the carrier 46, the latter being slotted at (158), Fig. 4, not shown) to permit the separation from the carrier 46. The lower finger 152 pushes the apple upwards relative to a carrier housing 273 of the upper finger 153 so that the latter is forced to retract and allow the apple to be impaled on a fork 193. The lower finger is then lowered and rotary cutters 337, 338 commence to peel the apple. A core tube 238 is then caused to pass upwardly into the apple around the core and when it is retracted it draws the apple downwardly off the fork 193. Further downward movement of the core tube 238 causes the apple to be stripped off the tube 238 by a member 251 and discharged to a shoot 251. A similar apparatus is described in Specification 1,224,203.

Title: Improvements in trench mortars and like guns
IPC: F41A19/13
Filed: 1920-05-29
Abstract: 168,396. Atkinson, H. R. May 29, 1920. Ordnance, muzzle-loading; breech mechanism. -The firing-pin of a muzzle-loading Stokes mortar is made operable as a percussion striker by a slip-lock mechanism. but may be locked in the protruded position so that it functions in the usual manner when a projectile is dropped into the gun. For firing at low elevations, the striker is held retracted by a safety catch during the leading operation, and is then released by a sliplock mechanism operated by a hand-lever. Fig. 2 is a vertical section and Fig. 3 a sectional under-plan of the base-cap a of a mortar embodying one form of the slip-lock firing-mechanism. The movable firing-pin c is shown locked in the protruded position by a spring-controlled pin k. When this pin is withdrawn, the firing-pin may be retracted by a cocking-lever h, through the medium of a pawl l, against the action of the spring d. A safety-catch n engages a notch in the firing-pin at half-cock, so that the mortar may be loaded with safety. When the cocking-lever is fully operated, a vertically-sliding pin n' is pushed upwards by the lever and lifts the safety catch, and the pawl l escapes through a notch in the lever permitting the spring d to actuate the firing- pin.

Title: Improvements in and relating to devices for automatically varying the ignition timing of internal combustion engines
IPC: F02P5/06
Filed: 1935-05-20
Abstract: 440,705. Timing ignition. FORD MOTOR CO., Ltd., 88, Regent Street, London. May 20, 1935, No. 14729. Convention date, May 19, 1934. [Class 7 (iv)] In devices which include speed-responsive mechanism for advancing the time of ignition together with mechanism normally having a retarding effect and consisting of a brake member controlled by the induction pipe suction, a cam-slot connection between the advancing and retarding mechanisms effects an initial advance by the brake member as the throttle is opened from idling position and before the speed-responsive mechanism becomes operative, the cam-slot connection also serving to amplify the action of the brake. Fixed to the interrupter cam 14 is an annular plate 18 in the ears 19 of which are fixed pivot pins 20 for the centrifugally-acting masses 21. At about the middle of each mass is fixed a pin 23 which at one end works in a radial slot 13 in a plate 12 on the driving shaft. At its other end the pin 23 carries a roller 24 working in a cam-slot 25 in the plate 26 which is loose on the cam 14 and engaged by the spring-pressed brake member 30. The space at the back of the brake shoe is in communication with the engine induction pipe by way of the pipe 34. While the engine is idling the brake is inoperative, and springs 40 draw the plate 26 in a clockwise direction (Fig. 5). Immediately the throttle is opened, suction decreases suddenly, the brake becomes effective and retards the plate 26 which is then moved counter-clockwise relative to the cam-plate 18 ; the rollers 24 are forced outwardly by the slightly rising cam-surface 43, and the mass-pivots 20 with the cam plate are drawn through an angle of two degrees thereby advancing the spark. During normal running resistance occasioned by the brake will, through the cam-faces 44 urge the rollers inwardly.

Title: New polyesters
Inventor: AITKEN ROXBURGH RICHMOND
IPC: C08G63/20
Filed: 1966-04-04
Abstract: Polyesters are made by reacting (a) adipic acid or an alkyl ester thereof with (b) a mixture of glycols comprising 10 to 50 mol per cent 1:6-hexanediol and 10 to 90 mol per cent 1,2-propylene glycol or 1,3-butylene glycol or a mixture thereof. The reaction mixture may also contain (c) a monocarboxylic acid, e.g. caproic, lauric, stearic, palm kernel or coconut acids and/or (d) a monohydric alcohol, e.g. n-hexanol, 2-ethylhexanol, n-decanol, n-dodecanol or various alcohols obtained by the carboxylation of olefins.  Up to 17.5 mol per cent of the adipic acid may be replaced by other dicarboxylic acids, e.g. succinic, glutaric, suberic, azelaic, sebacic, 3-methyladipic, 2:4-diethyladipic, 2-ethylsuberic, phthalic, isophthalic or 4:41-diphenyldicarboxylic acid.  Similarly up to 17.5 mol per cent of the glycols (b) may be replaced by other glycols, e.g. ethylene-, 1:2-butylene-, 2:3-butylene-, 1:4-butylene-, 1:5-pentylene-, neopentylene-, 1,10-decylene-, diethylene- or dipropylene glycols.  The polyesters are primarily used for plasticizing polyvinyl chloride and copolymers of vinyl chloride with vinyl acetate, unsym. dichloroethylene, styrene and esters, nitriles and amides of acrylic, methacrylic, fumaric and maleic acids.  They may also be used for plasticizing chlorobutadiene and butadieneacrylonitrile polymers, chlorinated vinyl chloride polymers, chlorinated rubber, nitrocellulose, ethyl cellulose and cellulose acetate.  The plasticized polyvinyl chloride composition may also contain a liquid barium-cadmium complex as a heat stabilizer or a polyisocyanate to assist in good adhesion of the composition to a substrate.

Title: Tape transport apparatus
IPC: G03B21/43
Filed: 1974-04-04
Abstract: 1429134 Tape transport apparatus NORDDEUTSCHE MENDE RUNDFUNK KG 4 April 1974 [4 Aug 1973 (2)] 14964/74 Heading G2E [Also in Divisions G4-G6] In apparatus for feeding a record-carrying tape such as a film strip 3 from a delivery spool 2 to a storage spool 12, the tape is scanned to produce a signal dependent on the speed of the tape, and if the signal is not present the tape is rewound on to the spool 2. Thus if the tape has left the guiding channel, or not been properly accepted by the storage spool, the re-winding means is activated. When the apparatus is initially switched on, a slide 38 is driven by motor 33 in the direction of arrow 50. A belt 41 passing round pulleys 39, 40 is carried forward into engagement with the tape on spool 2 and hence drives the spool clockwise. A stripper finger 52 engages the leading end 53 of the tape and guides it into a track 4. This carries it past the scanning means 6, and a further scanning means 5 for reproducing the images on the film strip on a television screen. It is now picked up by a capstan drive and guided to the storage spool 12. This has a number of curved blades 69, between which are suction intake orifices 70, Fig. 4 (not shown). As spool 12 is driven clockwise, a current of air is generated which helps to carry the leading edge of the film into entrainment with the hub and flanges of spool 12, and hence winds on to it. As the perforations 10 in the film strip pass the light source 7, a series of pulses is produced by the photo-cell 8, which are passed to a logic circuit 20. The motor 13, which drives spool 12, has a series of black and white markings 17, on which is directed light from a source 15. The reflected light is received by a photo-sensitive element 16, the resultant pulses also being passed to the logic circuit 20. If, after movement of strip 3 past the scanning means 6 has been initiated, no pulses are received by logic circuit 20 after a given delay period, indicating a transport defect, a motor 26 is energized, which brings a friction roller 27 into contact with spool 2 and rewinds on to it any strip which has been fed from it. If the strip has been correctly accepted by spool 12 and is winding on to it, this exercises a braking effect on the spool, which alters the frequency of the output pulses 23 from element 16. The logic circuit compares these pulses with those from element 8, and if they correspond approximately, indicating that the strip is being properly wound on to spool 12, this is allowed to continue. If the frequency 23 is still that of the unbraked spool, the rewind motor 26 is again energized to rewind the strip back on to spool 2. When the strip has come to an end, no more pulses appear from element 8, so that motor 26 is once more energized to rewind the strip. This can also be effected before the strip has come to an end, by actuating a control panel 29 to simulate the absence of pulses from element 8.

[Also in Group XXXVIII] A transducer for producing pneumatic pressure signals proportional to electrical currents comprises a pivoted plate 334 (Fig. 2) carrying coils 190, 192 in the air gaps between two magnets 316, 318 and cylindrical, soft-iron cups 312, 314, the intensity of the current in the series-connected coils determining the twist on the plate 334 and the amount of movement of a flap 358 co-operating with a nozzle 360 which is the outlet of pressurized air fed from a pipe 366, the resultant pressure in the pipe being proportional to the current in the coils 190, 192. The magnets 316, 318 may be adjusted to be symmetrical inside their cups 312, 314 by screws 313, 315. The plate 334 is supported by a cross-piece 340 to which are attached cross-flexures 350, 352 (Fig. 4), assembled to a support 354 secured to the base plate 310, and the flapper arm 358. Interaction between the current in coils 190, 192 and the magnetic field produces a torque on plate 334 which is counterbalanced by a bellows 370 (Fig. 3) acting at 369 on cross-piece 340, fed from a pipe 376 whose internal pressure is arranged to be proportional to that in pipe 366, and in the balance position the pressure in pipes 366 or 376 is proportional to the current in coils 190, 192. The zero position of the transducer is set by an adjustable spring 380 acting at 379 on the cross-piece 340.
