Title: Improvements in Sorting into Lenghts or Dragging Bristles, Hair and the like.
Inventor: TIMMIS ALBERT HENRY
IPC: A46D1/055
Filed: 1918-02-26
Abstract: 123,580. Timmis, A. H. Feb. 26, 1918. Brush-making machines.-Bristles and the like are sorted into lengths by subjecting their rout ends to pressure alternately on opposite sides against a resisting surface so as to bend them to and fro. In the apparatus shown in Fig. 3, the bristles b', after being combed and prepared in the usual manner, are placed in a holder b and held in position by the spring-pressed pusher c. The holder b is then gradually fed forwards so as to bring the bristles into engagement with a pair of combs f, g. The lower comb f is fixed in position, but the upper comb is reciprocated longitudinally so as to bend the longer bristles to and fro and thus cause them to rise when they are engaged by the rollers l and passed on to the travelling band n. After all the longest bristleshave been separated, the bottom of the holder b is raised and the operation repeated for the next set of bristles, and so on.

Abstract: 952,248. Control of A.C. motors. BABCOCK & WILCOX Ltd. Jan. 30, 1963 [Jan. 30, 1962], No. 3550/62. Heading H2J. A fluid heater cleaner has a retractable lance driven by an induction motor 1 which is supplied from three phase generator 3 through reversing contacts 2a, 2b. If one phase of the supply is interrupted during forward movement of a lance, it is not possible to reverse the drive unless the star point of the motor is connected to the neutral point of the supply. For this purpose, a filter 12 is associated with current transformer 7 so that the frequency of the signal applied to the filter changes when a fault develops in one of the phases of the supply. A trigger 16 is then operated through amplifier 13 and filter 17, so causing trigger circuit 19 to de-energize relay coil 20. This causes contacts 5b to complete a circuit between the star point of the motor and the neutral point of the supply. Alarm contacts 22 are closed at the same time. Should a break occur in the lead 4a during normal operation, coil 27 is de-energized to close switch 28. The trigger circuit 19 then acts to de-energize the coil 20 and close the alarm contacts 22. Resistor 30 and capacitor 31 provide a delay in the operation of the trigger 19 to prevent a false alarm indication. Transient surges are suppressed by resistor 26 and capacitor 32 associated with coil 27. The motor 1 is one of several adapted for sequential operation. Specification 636,052 is referred to.

Filed: 1973-01-25
Abstract: 1404401 Delivering sheets INTERNATIONAL BUSINESS MACHINES CORP 25 Jan 1973 [6 March 1972] 3711/73 Heading B8R Sheets 25, Fig. 4, delivered from between belts 10, 15 on to a stack support platform 22, deflect upwards a spring member 30 as they pass over the support, whereupon a shutter plate 32 causes a signal to be emitted by a photo-electric detector 40. At this time, the next sheet has not reached a second photo-electric detector 45, which emits no signal. When the stack reaches a predetermined height, the detector 40 remains activated after the sheet has settled on the stack, so that when the next sheet reaches the detector 45, signals from both detectors activate a motor 50, Fig. 3, to lower the platform a predetermined distance equal to several sheet thicknesses, whereupon the cycle is repeated. The motor rotates a lead screw 58 to lower a nut 59 and allow a member 23 supporting the platform 22 to move downwards along a rod 51. When an upper limit switch 70 is closed by the nut 59, after the operation of a start key causes the motor to move the platform upwards, the motor will stop and the circuits are ready for normal operation. When the stack is full, the nut 59 closes a lower limit switch 71 to prevent further downwardly-directed rotation of the motor, and to light a "stack full" lamp. In a "jam" situation, Fig. 8, the spring member 30 will be held upwards to activate the detector 30 long enough for two successive signals to be emitted by the detector 45 by following sheets, opening two immediately consecutive "lower" instructions, the effect of which is to stop the sheet transport and light a "jam" lamp.

Title: Improvements in or connected with feed-water regulators for boilers
IPC: F22D5/16
Filed: 1930-02-04
Abstract: 347,756. Feedwater regulators for steam boilers. DUNN, H., 88, Chancery Lane, London.-(Northern Equipment Co. ; 111, West 11th Street, Erie, Pennsylvania, U.S.A.) Feb. 4, 1930, No. 3719. [Class 123 (ii).] The feedwater regulator in a steam boiler system comprises two co-operating elements, one of which encloses the other and either of which is connected by pipes to the steam outlet at points of unequal fluid pressure so that the water level in the enclosing element varies with this pressure difference. The co-operating elements may comprise a generator 80, Fig. 1, surrounding an enlarged part 87 of a pipe 81. The latter is connected to the steam main 82 on opposite sides of the orifice 83. Variation of pressure through the orifice varies the level of condensate in the vessel 87. The heat flow into the generator 80 alters accordingly and the variation of vapour pressure in the latter varies the pressure in the diaphragm chamber 88, the diaphragm 74 being connected to the plunger of the feedwater valve 101. A second pair of elements 77, 78 also connected to the diaphragm chamber assists in maintaining the water level in the boiler within desired limits. In a modification, the elements are replaced by a float 89, Fig. 2, surrounded by a chamber 94, the latter being connected on either side of the orifice. The float controls the plunger of the valve 93 through a lever-cam system.

Title: Apparatus for treating cinematograph film
IPC: G03C7/22
Filed: 1946-02-06
Abstract: 616,168. Photographic processing apparatus. TECHNICOLOR MOTION PICTURE CORPORATION. Feb. 6, 1946, No. 3721. Convention date, June 15, 1945. [Class 98 (ii)] Apparatus for registering with a main film a number of auxiliary films, each of which is fed to and supported by an endless carrier, the main film being fed successively from carrier to carrier, comprises means for driving at constant equal speeds the sprockets feeding the films and a second means for driving the carriers at speeds controlled by means which seeks to keep constant the length of film between the carrier and the next driven sprocket. As shown, the apparatus is arranged for the imbibition printing of subtractive three-colour kinematograph films and comprises three substantially identical printing stages Y, C, M, in which all the driven film-feeding sprockets, indicated by crosses, are driven by a single motor 33. A blank film 7 (the " main " film) from a supply reel 9 passes over a sprocket 10 and safety loop-forming rollers 11, 12, 13 to a tank 14, where it is wetted before passing to the carrier, which comprises a pin belt passed, in order, around sheaves 3, 4, 5, 2 and on which the blank film is seated by a roller 16. The yellow matrix film 8 (an " auxiliary " film) passes from the spool 17 over a sprocket 18 and loop-forming rollers 19 to dye and rinsing tanks 20, 21, leaving the latter over a tensioning pulley 22, and is guided beneath a roller 24 on to the belt in superposition on the blank film 7. After passing together round the sheave 2, by which time the blank has imbibed the dye, the two films are separated as they pass round the roller 25. Thence the matrix film passes over a " floating " pulley system 26 to a washing tank 27, and then by way of a drying chamber 28 to a take-up spool 29; while the blank passes through a drying chamber 30 and thence successively to the cyan and magenta printing stages C, M, finally being wound up on a spool 32. At each printing stage the speed of the pin belt is governed by a variable speed motor 34 adjusted, through a pulley system 41, 42, 43 and a bell crank 37, by variations in the length of film between the carrier belt and the next driven sprocket which cause vertical movements of the pulley block 26. Reference is made to using the apparatus for stripping emulsion layers from multilayer films and transferring them to new supports, when the multilayer film would follow the path of film 7 and the separate supports those of film 8, the dye tank 20 being dispensed with.

Abstract: 432,900. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and RENSHAW, A. P. B., Brookwood, Dickerage Road, Kingston Hill, Surrey. Feb. 5, 1934, No. 3748. Drawings to Specification. [Class 118 (ii)] The cycle time of a progressive type roadtraffic control system is continuously adjusted in accordance with traffic flow over one or more selected intersections in the system. A number of units are controlled from a master timer and a selected unit is controlled by vehicle-operated means. If the cycle time of the master timer during any cycle is less than that of the vehicleactuated unit the speed of the master timer is reduced whilst if the vehicle - actuated unit completes its cycle first, the unit is arrested, with right-of-way on the main road, until the master has completed its cycle and is then restarted, the speed of the master being at the same time increased. The speed of the master unit is controlled by a resistance varied in steps by two magnets, the control making a 4 per cent. variation in the speed one way or the other depending on whether a relay controlled by the master operates before or after a relay controlled from the vehicle-controlled unit. The other units in the system may be non-vehicle controlled units, may have pads in the side road only, the right-of-way being given to the side road at appropriate times only if a call from the road has been received or may be of vehicleoperated type, being controlled from the master for maximum timing only. The master controller may be adjusted in accordance with the average operating times of a number of vehicle actuated units. Specifications 346,294 and 403,732 are referred to.

Abstract: 1500022 Luminescent screens THOMSONCSF 28 Jan 1975 [29 Jan 1974] 3756/75 Heading C4S [Also in Division H1] A luminescent screen comprises a substrate 1, and a layer 40 of grains 4 with interstices therebetween so that the luminescent material 7 is in the form of islands. In the case of spherical grains 4, phosphor 7 may be 150 to 200 Ám. cylinders separated by channels 6 and constitute light-guides. The high refractive index of the scintillator (e.g. up to 1À7 or 1À8) limits lateral scattering and reflections at the scintillator-barrier or -photocathode interface. Grains 4 may have a dimension of 20 to 70 Ám. and channels 6 may have a transverse dimension of a few tens of nanometers and up to a few microns. The grains are preferably of glass, e.g. the system PbO, TiO 2 , BaO, Al 2 O 3 , B 2 O 3 , ZnO, the refractive index of which is 2 to 2À1, and the reflected rays as in Fig. 4 (not shown), then experience total refraction. The glass balls serve also as a chemical barrier between scintillator and substrate which may be of Al or Be rather than glass for X-ray and y-ray input. In fabrication, a few microns thick layer of a methacrylate binder is painted on an Al spherical cap, the layer of balls applied, sodium silicate applied by atomizing to the free faces to ensure cohesion of the balls and substrate in the final screen, and the phosphor deposited (e.g. by vaporization). Passage through a tunnel furnace and a specified heating cycle removes the organic binder. Subsequently, a photocathode, e.g. a complex of Sb and alkaline earths, is deposited to 100 Š. A barrier and electrically conductive layer may be provided between phosphor and photocathode. The screen may be in an image converter (Fig. 5, not shown). Also instanced is neutron excitation, and radiology applications. Phosphors may be alkali halides, e.g. CsI, KI, NaI.
