Title: Improvements in fastening devices for doors and the like
IPC: E05B63/20
Filed: 1930-06-10
Abstract: 356,293. Sliding latches. MILLEDGE, S. Z., 14, Hartington Road, Grove Park, Chiswick, London. June 10, 1930, No. 17787. [Class 44.] A bolt 8 is withdrawn by a pin 6 attached to a U-shaped plate 4 which slides parallel to the bolt when either projection 2, attached to the door handle, is turned. A spring 10 presses on an edge of the bolt, Fig. 2, and forms a couple with the line of action of the draw-pin 6 on the bolt so that in the withdrawn position the bolt is turned sideways and a notch 12 grips the edge of a plate 15 to hold the bolt in the retracted position. The bolt is released by a pin 14 striking the door jamb and pressing sideways on the bolt. In a modified form the striking pin is dispensed with and a projecting rim on the striking plate of the door-post pushes the bolt sideways when the door is closed. In this case the bolt end has two notches 12 and a rib on one side, the rib contacting with the projection on the striking plate.

Title: Improvements in or relating to the chlorination of diphenyl
IPC: C07C17/12
Filed: 1930-06-10
Abstract: Resin-like products are obtained by chlorinating diphenyl up to the hexachloro derivative in the presence of a chlorine-carrier with maintenance at a temperature only slightly above the melting point of the mixture when the said melting-point is above, or p  about normal temperature.  Curves are given showing the relation of the melting-point of the reaction mixture and the reaction temperature to the proportion of chlorine introduced.  In an example, diphenyl is chlorinated in presence of antimony trichloride until a hard resin is obtained at about 6 molecular parts of chlorine; other catalysts specified are iron and phosphorus trichloride.

Filed: 1947-07-07
Abstract: 624,349. Machinery guards. FORD MOTOR CO., Ltd., and LEEK, J. W. July 7, 1947, No. 17838. [Class 80 (iv)] A safety device for power presses and the like comprises a stop f1 preventing operation of the pedal g controlling the press clutch until it has been retracted by fluid operated means actuated by the motor b or other prime mover of the machine. As shown, in which a punch press a is actuated by an electric motor b, the latter when engaged drives a vacuum pump d which is connected by a pipe h to a cylinder e. A spring-loaded plunger f in the cylinder e carries the stop f1 which is thus withdrawn when the motor b is started. In a modification, two push button valves are provided in fluid pressure line h, so that before the stop f1 can be withdrawn the valves must be manually actuated, thus keeping both hands out of the danger area. In a second modification a further valve may be provided in the press tool to prevent actuation if two pieces of work are inserted in error. The plunger f may be arranged to be actuated by fluid pressure instead of vacuum.

Abstract: 644,363. Automatic shuttle changing; weft feelers; checking shuttles. BUTIN, E. A. Dec. 23, 1946, Nos. 37729 and 37730. Convention dates, Dec. 17, 1945, and Nov. 29, 1946. [Class 142(iii)] During shuttle changing, the shuttle box is disconnected from the slay and remains at back centre. Cop feeler Fig. 4.-Every time the shuttle arrives at the replenishing end of the loom, a cam 19 acting through a lever 20 allows a spring-loaded feeler 35 to enter the shuttle, and then withdraws it by means of a collar 36. When the weft is depleted, the feeler enters far enough for a shoulder 61 on a rod 37 to engage the collar 36, so that withdrawal of the feeler turns a lever 38, thereby releasing a lever 23, which drops into the path of a cam 24 to initiate shuttle changing. A cam 22 subsequently returns the lever 23 to the position shown. Shuttle changing.-The cam 24, Fig. 4, has a lateral lobe which, when the lever 23 drops as described above, encounters a roller 23b; since the lever cannot move laterally, the cam shaft is moved endwise, bringing the other cams on the shaft into line with their followers to effect various operations concerned in the shuttle change. A cam 27, Fig. 7, moves a lever 4 down a cam slot 9, thereby uncoupling the shuttle. box B from the slay 3 and moving the front wall 6 of the box away from the near wall 1b; the shuttle box stays at back centre while the slay continues its oscillations. A fresh shuttle 42 is lowered into the box B by a cradle 39a, whereupon the lever 4 rises to close the shuttle box. Meanwhile, the slay returns and a hook 5 is engaged by the lever 4, see Fig. 9. As the slay moves forward, it takes the shuttle box with it (the box back being slotted at 1f, Fig. 3, to clear the cradle 39a) but, as the box B is not then in line with the shuttle race, the depleted shuttle 41 arriving from the other end of the loom enters a compartment C. When the slay moves rearwards again, the shuttle race comes into line with the box B and the lever 4 can rise to the top of the slot 9 where it engages the front edge 5a of the slay. The front 44 of the compartment C then swings open, allowing the depleted shuttle 41 to fall through a hole 3b in the slay. Finally, the cam shaft 16 moves endwise to its normal position. Braking shuttle, Fig. 3-A spring 54 acting through a lever 21 is normally prevented by a dog 50 from loading a swell 13. When the shuttle enters the box, it displaces a roller 47 to release the lever 21 which then presses on the swell. The pressure is removed before picking by a cam 18 and, after the shuttle has left the box, a spring 53 re-engages the dog 50 with the lever 21.

Title: Recording Apparatus
Filed: 1967-04-20
Abstract: 1,181,414. Control of A.C. motors. MINNESOTA MINING & MFG. CO. 20 April, 1967 [21 April, 1966], No. 18318/67. Addition to 1,103,699. Heading H2J. [Also in Divisions G3 and G5] A magnetic tape 10 passes over a drum 15 which carries head 16 and is driven by induction motor 28 coupled to D.C.-excited braking motor 39. For the recording operation, a video signal from source 50 is applied to stage 51 which reinforces the synchronizing components of the video signal. The output of stage 51 is added to that of bias oscillator 54 for application through transformer 64 to head 16, a trap 53 preventing the output of oscillator 54 from being applied to stage 51. A vertical synchronizing signal is derived from the stages 68, 70, and is recorded along an edge of the tape by head 21. The vertical synchronizing signal is applied to phase comparator 79 which also receives drum speed-responsive pulse signals from magnet 80 associated with head 81. The error signal is applied to the braking motor 39 through lead network and amplifier 85 which reduces hunting. Sound is recorded along an edge of the tape by head 20 associated with bias oscillator 91, amplifier 90, and signal source 89. For the playback operation, the signal picked up by head 16 is passed through transformers 64, 101, to amplifier 120 which is connected through unit 122 to video output device 124. The unit 122 is controlled by unit 126 which removes horizontal synchronizing signals from the video signal and also regulates the operation of multivibrator 130 which fixes the interval between the trailing edges of the horizontal synchronizing signal and of the horizontal blanking signal. The unit 122, during the interval when head 16 crosses over the edges of the tape, accomplishes vertical synchronizing and blanking under the control of multivibrators 132, 134. A second head 136 near the drum is in radial alignment with the head 81 and responds to the passage of the magnet 80. The head 136 applies clamp pulses to amplifier 138 which is connected to multivibrators 132, 134. The circuit described serves to clamp the reproduced video - signals and to restore low frequency components in addition to blanking portions of the reproduced signal due to head passage over the edges of the tape along which the sound and control signals are recorded. The vertical synchronizing signal, which was lost during the recording process, is also re-inserted. Comparator 79 receives speed-responsive signals from head 81 and reference signals from head 21. The error signal controls the braking motor 39.

Abstract: 1,169, 595. Combined diffusion pump and ion pump. INTERNATIONAL STANDARD ELECTRIC CORP. April 21, 1967 [April 25, 1966], No.18478/67. Heading F1E. A vacuum pump includes a diffusion pump and an ion pump so arranged that during one mode of operation gases being pumped pass through an ionization chamber 10 into the diffusion pump condensing chamber 5, an ion target 17 being provided on a wall surface of the condensing chamber and ions formed in the ionization chamber are accelerated towards the ion target and entrapped in a stream of condensed diffusion pump vapour flowing over the ion target. Pumping fluid 1 which is heated by heater 2 rises as a vapour in container 3 and flows via conduit 4 into condensing chamber 5, surrounded by cooling coils 6 which condense the vapour. The condensing vapour entraps gas molecules entering condensing chamber 5 and moves towards the bottom of chamber 5 where the gases are removed by a forepump connected to outlet 8. Liquid flows back via connection 9 to the primary reservoir 1. A second condensing coil 15 condenses a desired portion of the vapour flow to give a continuously flowing film 16 flowing over the ion target 17. Electrons produced by ionizer 12 move in a circular pattern under the influence of magnet 18 to ionize gas molecules entering via inlet 7 and also any back streaming pumping fluid molecules which enter chamber 10. The ionized gas molecules under the influence of electric fields produced by anode 11, auxiliary cathode 13 and ion target 17 embed themselves in the flowing film 16 and are carried thereby to the bottom of the condensing chamber 5 to be pumped out by the forepump. The apparatus may be used independently as either a diffusion pump or an ion pump.

[Also in Division B8] A conveyor belt, for carrying and draining wet sand or gravel, has a slotted rubber strip 12 overlaying and spaced from its flat central portion 11, forming drainage ducts 15 from which water leaves by spaced outlets 18. The edges of strip 12 are welded or bonded to the belt, leaving gullies 17 traversing the joints, whereby water from the side regions of the belt beyond strip 12 (Fig. 1, not shown) enters ducts 15. Gullies 17 may be preformed in strip 12 and/or belt 10, or formed by spaced prongs during the welding, or formed in separate strips which are bonded between belt 10 and strip 12. Ducts 15 are formed by one or more longitudinal ribs 14 or by spaced blocks, and are divided transversely by ,partitions 20, located adjacent outlets 18 to prevent water by-passing the outlets. Outlets may be located on both sides of each partition to avoid selective assembly of a belt on a longitudinal incline. Slits 21 may be made in strip 12 by blades projecting from a press platen, and opened to the desired extent by stretching strip 12 during bonding to belt 10 (Fig. 6, not shown). Under edges of slits may be chamfered by a conical abrasive wheel. Alternatively, strip 12 comprises a series of transverse sections bonded together at spaced locations to form a similar structure, gullies 17 being likewise formed. As the belt passes over end rollers, the slits open out and washing water is applied. A gutter below the upper run of the belt prevents water from reaching the return run.
