Title: Improvements in or relating to type-writing machines
IPC: B41J17/00
Filed: 1934-01-12
Abstract: 423,325. Typewriters. UNITED AUTOGRAPHIC REGISTER CO., 5000, South California Avenue, Chicago, U.S.A. Jan. 12, 1934, No. 1218. Convention date, Jan. 13, 1933. Addition to 382,783. [Class 100 (iv)] Web feeding and guiding arrangements.- The standard and associated web-gripping devices comprised in the web-manifolding means described in the parent Specification are replaced by a standard having an extensible section provided at the top with a web-gripping device, the arrangement rendering it unnecessary for the operator to reach very high during manipulation. In the apparatus shown in Figs. 2 and 6, a web-gripping device D<3> is mounted on a slide D supported by a standard D attached to a web-guide C which is secured to the carriage B. The web-guide consists of a guide-loop having an arm 14 carrying a bar 15 provided with guide-fingers. Brackets C<2>, adjustably attached to the guide-loop by means of screws and sliding keepers, are mounted on the tabulator-stop bar on the carriage. The standard D is provided with a bracket 21 which is attached by means of a screw 13 to the web-guide. The downwards movement of the slide D<1> is limited by engagement of a sleeve 30 thereon with the top of the standard. The slide is yieldingly held in the upper position by engagement of a lug at the bottom thereof with catch consisting of a loop at the lower end of a leaf-spring secured in the standard. A loop at the upper end of the leaf-spring bears frictionally on the slide. The web-gripping device D<3> comprises a bracket 31 secured by a screw 32 to the slide. A gripper 34 is secured to a shank 34<a> which passes through a block 33 trunnioned in the bracket, a spring 36 being arranged between the block and gripper, and the shank being provided with an adjusting-nut 35. A light spring 37 normally holds the gripper in contact with a stop 31b. When the webs 40 are fed between the gripper and the sleeve 30, the gripper is swung upwards and then grips the webs. On retraction of the webs, the gripper is swung downwards and grips the webs more firmly. A handle D<2> for manipulating the slide and guiding the webs consists of a wire member which is formed with a loop 26 and is pivoted by means of pintles 27 to the slide. When the slide is in the lower position, the platen is turned to feed the webs into engagement with the gripper, the feed-rollers are released from the platen, the slide and webs are raised by means of the handle, and the carbon sheets are retracted, the slide being held by the catch. The feed-rollers are then re-engaged, and the webs are retracted by turning the platen, the gripper causing the slide to move downwards with the webs until the slide is arrested in the lower position, whereupon the gripper yields to permit of further retraction of the webs.

Title: Improvements in or relating to hydraulic jacks
IPC: F15B15/26
Filed: 1943-01-26
Abstract: 564,590. Hydraulic transmission of power. HOLLAND, C. D., MESSIER AIRCRAFT EQUIPMENT, Ltd. (formerly RUBERY OWEN MESSIER, Ltd.), and CALDWELL, H. B. Jan. 26, 1943, Nos. 1326 and 17577. [Class 69 (ii)] In hydraulic jacks, e.g. for operating under-carriages &c. in aircraft in which a latch member 17 on the piston engages behind an abutment 16 in the cylinder and is locked in position by a member 18, the piston and member 18 operate a signalling device. The member 18 carries a pivoted switch operating arm 26 having a cam slot 27 engaged by a pin 37 on a sleeve 35 slidable in the cylinder. As the piston approaches the end of its stroke, latch 17 engages member 18 and pushes it to the right, carrying the sleeve 35 with it until the latch engages the abutment 16. Member 18 is then returned by a spring 20 into locking engagement with the latch while sleeve 35 remains stationary, thereby rotating the cam arm 26 and operating the signal switch. When liquid pressure is applied to the jack, the locking member is first moved back, thus breaking the switch and releasing the latch before the piston moves. The locking member may be withdrawn by a manually-operable member 30 in the event of liquid pressure failure and the weight of the parts is sufficient to extend the jack. In modification, the switch is carried by a sleeve moved axially by abutment with the main piston and operable by a tappet carried by the locking member. In all cases, the signal is operated only when the piston and locking member are in the locking position. A similar locking device is provided at the other end of the jack. Specifications 527,225 and 548,386 are referred to.

Abstract: 1442263 Bridging-clutch control ZAHNRADFABRIK FRIEDRICHSHAFEN AG 11 Jan 1974 [12 Jan 1973] 01363/74 Heading F2D A valve 16a controlling application of pressure fluid to a piston 27 actuating a bridging clutch 25 of a hydrokinetic torque converter 20 is actuated automatically to engage the clutch when the ratio between the speeds of the input and output shafts 21, 23 reaches a predetermined value. Each shaft carries a counter disc 22, 24 with an associated pulse transmitter 2, 8 and the discs are so dimensioned and arranged that the frequencies of pulses delivered by the two transmitters are equal at the predetermined speed ratio. The frequency signals are fed through respective amplifiers 6, 9 to frequency analogue converters 7, 10 the voltage couputs of which, proportional to the frequencies, are fed to the inputs 4, 5 of a differential switch 3. When the input 5 attains the value of the input 4 the switch 3 operates and through an amplifier 15 and relay 16 causes the valve 16a to supply fluid to the piston 27. A feedback signal then passes through a line L3 to reduce the output from the converter 7 to zero so that the clutch is only disengaged thereafter when the input 5 falls below a datum value corresponding to a lower limiting engine speed applied to the input 4 from a setting regulator 1. The speed ratio at which the clutch is operated is modified by a kickdown switch 13.

Title: Improvement in brakes
IPC: F16D53/00
Filed: 1926-01-18
Abstract: 246,826. Rosenberg, R. H. Jan. 27, 1925, [Convention date]. Blocks and shoes acting on drums and on flat sides of discs; blocks and shoes.-In a brake of the kind comprising a pair of shoes adapted to grip a rotatable drum or disc, the shoes are carried bv a member freely movable in a direction at an angle to the surface with which they engage so that the pressure applied to the shoes is equalized and allowance is made for unevenness of the surface. The shoes mav be adjusted to take up wear. The brake shown in Figs. 1 and 3 comprises shoes 11, 12 freely mounted on pins 14, 15 journaled at the end of an arm 20 freely pivoted at 21 on a fixed arm 22. The shoes are held laterally against collars 16 on the pins by springs 19. The parts of the pins which carry the shoes are eccentric with respect to the parts mounted in the arm 20. The pin 14 is normally rigidly held in the split end of the arm 20 but can be turned by the head 24 to adjust the shoes in relation to the drum after slackening nuts 23. The pin 15 is adapted to be turned to engage both shoes with the drum 10 by an arm 26. As the arm 20 is free to swing about the pivot 21, the action of the brake is not interferred with bv any lack of concentricity of the drum. A similar arrangement may be applied to shoes acting on opposite sides of a disc. Two pairs of shoes diametrically arranged and independently operable may be provided. According to the Specification as open to inspection under Sect. 91 (3) (a), the invention may be applied to clutches. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to phenol-formaldehyde condensates and foamed products produced therefrom
Inventor: PRITCHETT ERIC GEORGE KEMP
IPC: C08G8/10
Filed: 1961-01-16
Abstract: One mol of phenol is condensed under alkaline conditions with 1-1.5 mols of formaldehyde until at least 90% of the formaldehyde has con-with the phenol, and the mixture is then vacuum distilled until a test sample of 100 grams of the mixture with 5 grams of ethyl alcohol will tolerate between 5 and 20 ml. of toluene at 25 DEG C. without separation of the condensate. The products are well suited for production of cellular products by addition of an acid hardening agent with or without a foaming agent, e.g. a volatile liquid such as di-isopropyl ether or a gas generator such as zinc dust, sodium carbonate, sodium bicarbonate or potassium nitrite which interacts with the acid hardener to produce gas; or benzene sulphonyl hydrazide which decomposes at the hardening temperature. A small proportion of polyvinyl acetate or polyvinyl acetal, e.g. polyvinyl butyral may be added to the reaction mixture of phenol and formaldehyde or to the hardenable mixture of condensate, hardener and foaming agent. Suitable acid hardeners are sulphuric, hydrochloric, phosphoric or an aromatic sulphonic acid.
Patent GB-400214-A (GB)
Title: Improvements in and relating to the production of separation negatives in regular pattern colour screen processes
IPC: G03C7/04
Filed: 1932-01-20
Abstract: 400,214. Colour photography. BECKERT, F., 2A, Shoot-up Hill, Cricklewood, London. Jan. 20, 1932, No. 1797. [Class 98 (ii).] Two processes are described for obtaining colour separation negatives from pattern screen negatives by means of a stop-out screen, i.e. one which stops out all colours but one of the colour screen patterns. The processes are contrasted with a process described in Specification 380,778. In one process a stop-out screen image is photographically produced on a slow silver-emulsion plate which is not bichromated. The image is developed (but not fixed), washed and resensitized with bichromate. The resensitized plate is exposed under the screennegative registered therewith, and is developed, fixed, and washed, thereby obtaining a reversed separation negative of one colour with the other colours blocked out. In the second process, the slow silver emulsion is applied to a plate coated with plain gelatin. The stop-out screen image is printed, developed and in this case fixed and washed. The plate is resensitized with bichromate, printed under the registered screen-negative, washed to remove unexposed bichromate and then dyed up with a suitable dye such as pinatype black, or nigrosine to obtain a grainless dye negative.

Patent GB-937373-A (GB)
Title: Flash distilling plant
IPC: B01D1/26
Filed: 1960-01-19
Abstract: A flash distillation apparatus, particularly for water, comprises a shell 1 divided by partitions 3 into compartments 4-6 kept at successively decreasing pressures, each compartment comprising (Fig. 2) a flash section 22 and a condenser section 21 which communicate through a de-mister 23.  Feed water supplied through inlet 12 flows through the feed duct 7 into the compartment 4, the characteristic feature of the invention being that the duct 7 is tapered in the direction of flow of the feed water.  The water passes from the duct 7 into the flash compartment 22 through orifices 9, impinging en route on a deflector 11a, and the vapour <PICT:0937373/III/1> <PICT:0937373/III/2> passes through the de-mister 23 into the condenser section 21, from which condensate passes via a channel 20a to pipe 30, which leads it to the corresponding channel 20a in compartment 5. Unevaporated feed from compartment 4 flows into compartment 5 through a pot 14 (Fig. 3), passing from compartment 4 down one side of a plate 17 and into compartment 5 up the other side of the plate.  Similarly, condensate and unevaporated feed pass from compartment 5 to compartment 6, whence excess feed is discharged through pipe 13 and condensate is withdrawn through outlet 31. The condenser tubes 24 pass through all the compartments 4-6 and sealing means (Fig. 4, not shown) are provided at the points where they pass through the partitions 3.  The tubes may be fed with cool feed water through inlet 27, the water leaving at a higher temperature through outlet 28 and passing to the inlet 12 of compartment 4, optionally after further heating.  The number of compartments in the shell 1 may be varied, and the whole shell may constitute a single compartment. Also, the plant may comprise more than one shell 1, and in this case the compartment 4 may be fed with condensate and unevaporated feed from a preceding shell, or the outlets from the compartment 6 may pass condensate and unevaporated feed to a succeeding shell, but in any event each compartment in the direction of flow of the feed is at a lower pressure than the preceding compartment.  Specification 937,374 is referred to.
