Abstract: 1,271,980. Making paperboard. PERSTORP A.B. 8 July, 1969 [8 July, 1968], No. 34246/ 69. Heading D2B. In the production of hard fibreboard by the wet process, a cation-active homopolymer or copolymer of vinyl acetate is applied to the surface of the wet mat, which is then pressed and cured. A surface dressing of finely ground sawdust may be applied before the polymer, or the two may be mixed and applied together When a copolymer is used, it may be crosslinking, e.g. one in which the other monomer is N-methylolacrylamide, N-methylolmethacrylamide, acrylic acid, acrolein, allyl glycidyl ether, glycidyl acrylate or ethoxy-ethyl acrylate. Part of the polymer may be replaced by hexamethoxymethylmelamine, melamine-formaldhyde precondensate or urea-formaldehyde precondensate. The examples compare boards that are untreated with boards treated with phenol-formaldehyde solution, anionic polystyrene emulsion, cationic polystyrene emulsion, anionic polyvinyl acetate emulsion, cationic polyvinyl acetate emulsion, cationic emulsion of a copolymer of vinyl acetate and methylolacrylamide, and mixtures of these last two with hexamethoxymethylmelamine.

Title: Improvements in combined electric circuit breakers and plug couplings
IPC: H01R13/713
Filed: 1933-12-08
Abstract: 429,933. Automatic circuit-breakers. WATKINS, A. E., 244, Dollis Hill Lane, Cricklewood, London. Dec. 8, 1933, No. 34560. [Class 38 (v)] [See also Group XXXVI] A switch associated with a plug coupling is tripped electromagnetically or electrothermally upon the occurrence of an overload or other abnormal condition and also when the plug is not in the socket. In the apparatus shown, the operating lever 22 is connected to the switch arm 15 through a knee-linkage 28, 30. In the event of an overload, the tail 44 of armature 36 of solenoid 34 breaks the knee-linkage by engagement with a pin 45 on link 30 and when the plug 12 is not inserted a spring-controlled lever 48 acted upon by the earth-pin 9 similarly operates armature 36. The tension of spring 38 controlling armature 36 may be adjusted by an arm 40 moving over a scale 43 to determine the current at which tripping is to take place. Solenoid 34 may be connected in shunt with a resistance which may be changed to enable the same device to be used for currents of different orders of magnitude. A shunt circuit may also comprise a bimetallic strip which under abnormal conditions causes the shunt to be opened after a predetermined delay, the increased current through the solenoid then causing the switch to be tripped instantaneously.

Title: Improvements in or relating to apparatus for arresting or preventing skid of motor road and other vehicles
IPC: B60B39/00
Filed: 1927-12-21
Abstract: 292,424. Carey, H. D. de M. Dec. 21, 1927. Slipping of wheels, preventing.- Apparatus for arresting or preventing the skidding of motor and other vehicles comprises two or more wheel carrying arms hinged to the chassis so that in arresting a skid the arm or arms in front of the centre of gravity of the vehicle as regards the direction of the skid will play no part, control means, independent for its action of any sideways motion of the vehicle, being operable by the driver to forestall the occurrence of a skid. The apparatus may, under the control of the driver, be used instead of a lifting jack and the skid wheels may be locked by braking devices. The arms a mounted to swing on horizontal shafts d which turn on vertical pivots r in brackets c secured to the chassis. The arms may be raised from the ground by any suitable mechanism and are held in the raised position against the action of springs g by the engagement of pins o on the arms with pivoted catches n connected by cables l to a weight k suspended from the vehicle so that when a skid occurs or brakes are applied, relative movement between the weight and the vehicle disengages the catches n and pins o. In a skid to the near side, the off-side wheel e is forced against the road and arrests the skid. The wheels e are set so that they normally tend to run inwards towards the central longitudinal axis of the vehicle. To prevent occurrence of a skid, the driver moves the arms a about the pivots r by means of cables y. This movement disengages the catches n and pins o and also sets the wheels e to the position shown in dot-and-dash lines in Fig. 2, so that they tend to run outwards with the arms a vertical as shown in dot-and-dash lines in Fig. 1. The weight of the vehicle is thus taken on the arms a and wheels e. When the driver releases the cables y, the arms under the control of springs w return to the normal position in respect of the pivots r and the wheels automatically run back towards the centre line of the vehicle. The arms a may be used instead of packs and may be operated to prevent running on a deflated tyre. The wheels e are locked to brake the vehicle independently of the road wheels by stops e<1> fixed to the vehicle and adapted when the arms a swing outwards, to enter circular grooves d<1>, Fig. 3, in the wheels. The stops abut against the free ends of springs c<1> located in the grooves so that the rotation of the wheels e is gradually arrested.

Filed: 1921-12-30
Abstract: 195,718. Jones, H. Sefton-, (Lorenz Akt.- Ges., C.). Dec. 30, 1921. Magnetic and thermionic modulating systems. -Comprises various arrangements for keying a continuous wave transmitter, the key being arranged to vary the choking effect of one or more iron-cored or other choking-coils in such a way as to suppress the emission when the key is open. Fig. I shows one arrangement in which the aerial-earth circuit a and a shunt circuit c3 are in parallel across the arc g. Each circuit includes an iron-cored coil t1, t2, and the key t is arranged to short-circuit one or other of the secondary coils according as it is open or closed. Closure of the secondary circuit annuls the choking effect of the corresponding primary coil and allows the oscillatory current to pass. In .another arrangement shown in Fig. 2, the aerial is direct-coupled to a coil s in the oscillatory circuit of an arc g and a choking-coil t3 is connected in the earth lead. The key t shortcircuits part of this coil when wave emission is desired. Fig. 6 shows a modification in which the arc a shunted by a condenser b is connected in the aerial circuit which also includes choking- coils c1, c2 in the aerial and earth connections. The two secondary coils are connected in series with a battery d in the key circuit, the battery serving to saturate the cores when the key is closed. Either of the choking-coils c1, c2 may be omitted. In Fig. 7 a thermionic valve f is connected as a series resistance in the circuit of the secondary coils, and the current passing from the source g is controlled by the key t which is arranged to give the grid a positive potential when in the sending position, and a negative potential in the non-sending position. Highfrequency voltage may be applied to the plate circuit instead of employing the separate source g. Several vaflves may be used in parallel when heavy currents are to be controlled. Specification 154,247 is referred to.

IPC: A41H37/08
Filed: 1962-09-22
Abstract: 982,428. Buckle threading apparatus. J. & P. JACOBS Ltd. Sept. 23, 1963 [Sept. 22, 1962], No. 36113/62. Heading E2A. A machine for threading brassiere strapping through an adjusting buckle comprises a holder 16 carrying a buckle 17, four pushers 6a, 7a, 12a, 13a, biased to neutral positions clear of the buckle but movable to pass through holes in the buckle, and a bar 19 for ejecting the buckle from the holder 16 and inserting another from a magazine 21. When using a hand machine, Fig. 2, an operator puts one end of strapping, cut to desired length and carrying a ring, across the buckle 17, depresses a handle 3b forcing the pusher 12a and strapping through the first hole in the buckle 17 and releases the handle 3b allowing spring 3f to return pusher 12a to its neutral position. Handle 24a is then moved from left to right causing wiper 24 to place the strapping under the second hole so that lifting handle 2b pushes the strapping up through the hole, then the pusher 7a falls back when released. Knee pad 26a is next operated moving arm 26 to hold the free end of the strapping clear of the second hole so that the other end, when placed over the buckle, can be pushed through the second hole by depressing handle 2b, moved under the first hole by wiper 24 and pushed up through it by lifting handle 3b. Knee pad 19b is finally operated to move rod 19 forward, ejecting the threaded buckle and carrying another in recess 19a into position between the jaws of holder 16, before being returned by spring 22. In an automatic machine, Fig. 4, (not shown) the parts are actuated by cams which may be mounted on a common rotating shaft. Strapping is supplied from a roll 49, Fig. 5, through a guide 50 under a weight 51 therein to an opening 52a in frame 52 thence through curved guide 54, a ring in holder 55 and a gate 56 to gripper 33, Fig. 7. When the desired length has passed a cam actuated guillotine 53 cuts the strapping, the gate 56 having been lifted just before for the arm 56a to raise the strapping enough to pull the ring clear of the holder 55. During cutting an arm 53a extending from the guillotine 53 contacts an arm 58a, reciprocating a stop member 58 to allow another ring to fall down the shoot 59. Another ram reciprocates a carriage Fig. 6 (not shown) under the guide 50 so that an inclined needle thereon moves the cut end of the supply of strapping forward to be gripped at the beginning of a new cycle. The gripper 33 slides to and fro between the ring holder 55 and the buckle holder 16 on a bar 34, drawn by an endless chain 36 driven by a motor controlled by switch 46 which also controls a solenoid 45 for closing the jaws 44 of the gripper 33. A cam 42 rocks the frame 35 carrying the gripper mechanism towards the holder 16 for the buckle 17 while the gripper 33 is carrying each end of the strapping in turn towards the buckle and rocks the frame 35 away from the holder 16 while the gripper is moving back towards the ring holder to fetch another end.
