Title: Improvements relating to vehicle-operated tread devices
IPC: G08G1/02
Filed: 1939-06-20
Abstract: 530,189. Road-traffic signalling apparatus; door-operating apparatus. CRAIG, G. L. June 20, 1939, Nos. 17979/39 and 9065/40. [Class 118 (ii)] [Also in Group XXV] Relates to a tread unit operated by the wheels of vehicles, for the purpose of actuating signals or other devices, opening and closing a gate, or closing a lighting and heating circuit when a vehicle enters a garage. According to the invention, the tread comprises a number of collapsable chambers arranged in a row extending in the direction of the travel of a vehicle, and connected to two actuating cylinders in such a way that when the chambers are compressed by the passage of the vehicle, fluid under pressure is supplied from the chambers to one or the other of the actuating cylinders according to the direction the vehicle has travelled across the tread. The tread unit consists of a number of collapsable rubber tubes 10, Fig. 1, arranged close together and parallel with one another transversely of the roadway. The tubes are connected in series with one another by pipes 12 to constitute a continuous channel, the ends of which are connected by pipes 14 to a pneumatic or hydraulic cylinder that operates, for example, a gate-operating mechanism such as that described in Specification 523,651, [Group XXV]. A vehicle wheel passing over the tread compresses and seals successive pairs of tubes and fluid is forced through the tubes, in the direction in which the vehicle is travelling, to the piston of the gate-operating mechanism or other device. Thus the gate mechanism can be made to operate differently according to the direction in which the wheel traverses the tread. A tread on both sides of the gate can be used to open and close the gate. The tubes may be composed of two rubber mouldings 18, Fig. 5, secured together by cement and by rivets 22 and stiffening strips 23. The internal corners 24 are bevelled or rounded to allow the tubes to flatten completely, and the internal surfaces are corrugated transversely, to prevent leakage of fluid past the flattened section. In a modification, the tubes 28, Fig. 7, are connected in parallel to headers 30, 32, non- return valves 34, 36 being fitted to the tubes so that liquid moves in one direction only, the tubes being refilled with liquid from a reservoir 64 after the passage of a vehicle. The liquid passes to the gate-operating mechanism through pipes 44, 46 controlled by a valve 42 which is moved in one direction or the other by two separate tubes 38, 40 placed in advance of the main tread units. The valve is moved, and the gate opened or closed, according to the order in which the tubes 38, 40 are compressed. The reservoir 64, and the connecting pipes, are dispensed with if the tubes are filled with air instead of liquid.

Title: Improved baking varnish and paint composition
Filed: 1956-06-12
Abstract: A composition of matter comprises 90 to 10 parts of a urea-formaldehyde resin and 10 to 90 parts of an oxidized liquid polymer or copolymer of a conjugated diolefin hydrocarbon of 4-6 carbon atoms containing 7 to 20 per cent of oxygen by weight.  In examples oxidized butadiene-styrene copolymers containing 7.5 per cent and 9.26 per cent of oxygen are mixed with 16.7 per cent of urea-modified melamine-formaldehyde resin, triazine-formaldehyde resin or urea formaldehyde resin and the compositions used as varnishes or enamels.  Specified polymers are those of butadiene, isoprene, dimethyl butadiene, piperylene, and methyl pentadiene, and copolymers of these monomers with styrene, para methyl styrene, dimethyl styrene, diethyl styrene, acrylonitrile, methacrylonitrile, methyl acrylate, methyl methacrylate, vinyl isobutyl ether, methyl vinyl ketone and isopropenyl methyl ketone. The oils may be prepared, e.g., by heating butadiene-1,3, straight-run mineral spirits, t-butyl hydroperoxide and diisopropyl xanthogen disulphide at 90 DEG  C. for 40 hours or by heating butadiene 1,3-styrene, straight-run mineral spirits, dioxane, isopropanol and sodium at 50 DEG  C. for 4.5 hours. The mineral spirits may be replaced by butane, benzene, xylene, naphtha or cyclohexane.  Oxidation is effected by blowing in air using as catalyst naphthenates or octoates of cobalt, lead, iron, or manganese.  Carbon black, titanium dioxide, and lead pigments, and solvents such as mineral spirits, naphthas, white oils, benzene and xylene may also be added.

Title: Improvements in rotary pumps or motors of the outwardly-sliding vane type
IPC: F01C21/08
Filed: 1957-06-11
Abstract: 818,025. Rotary pumps and motors. NEW YORK AIR BRAKE CO. June 11, 1957 [June 20, 1956], No. 18365/57. Class 110 (2). A rotary pump or motor of the outwardlysliding vane type having fluid-pressure loaded vanes is provided with valve means for creating a differential pressure between the fluid in the working chambers and the fluid acting on the roots of the vanes, and an actuator for operating said valve means in response to the pressure differential between the inlet and exhaust. A device comprises a rotor 19 disposed between side plates 16, 17 which are similarly ported and grooved for details of which Figs. 2, 3, 6 and 7 (not shown) should be referred to. The device also incorporates spring-loaded disc valves 21, 22 and annular disc valves 46 which contain four circumferential slots communicating with the recesses in the side plates and are resiliently attached thereto by channel-shaped springs 47, 48, screws 49 and spacers 51. Two flap valves 53 are mounted on each disc 46 to restrict the flow therethrough in one direction and to prevent it in the other direction in contra distinction to the valve 46. Operating as a motor fluid is fed to the working chambers via the valves 53 and the recesses in the side plate 16 and is discharged through the outlet 6 via the side plate 17. The valve 46 is unseated against the action of its springs 47, 48 by pistons 57 subjected to the pressure difference across the inlet and outlet conduits 5, 6 thereby permitting an unrestricted flow from exhaust ports in the plate 17 to the outlet 6. The chambers beneath the vanes are connected to the inlet and outlet conduits 5, 6, when the vanes reach the inlet and exhaust ports respectively. Between these transition positions the pressure applied to the vane chambers is reduced by the valves 21. Leakage fluid along the shaft is discharged through drain passages 15.

Title: Improvements in the preparation of hormones
IPC: A61K38/24
Filed: 1934-06-21
Abstract: The process described in the parent Specification for preparing the thyreotropic and gonadotropic hormones of the anterior hypophysis is modified by using strongly acid substances, such as picric, sulphosalicylic, trichloracetic or picrolonic acids, to precipitate the thyreotropic hormone, dissolving the precipitate in ammonia or alkali hydroxide, and reprecipitating the hormone by the addition of a large quantity of acetone or of a mixture of alcohol with ether or other lipoid solvent.  The mother liquors from the first precipitation may be concentrated in vacuo, the precipitating acid removed in any known manner, and the gonadotropic hormone recovered by salting out. According to one example fresh ground anterior lobes of hypophysis are shaken with kieselguhr in dilute sodium bicarbonate solution, the mixture is filtered and aqueous picric acid solution is added to the filtrate.  The precipitate is suspended in water, dissolved by the addition of ammonia, and the hormone precipitated by the addition of acetone.  Extracts or press juices of fresh hypophyses, or dry powdered fat-free hypophysis may be used as starting material.  The Specification as open to inspection under Sect. 91 refers also to the use, as precipitants, of heavy metal salts, such as lead acetate, silver nitrate or mercuric chloride, or of colloids, such as ferric hydroxide, alumina, or aluminium hydroxide produced by exposing aluminium amalgam to moist air.  This subject-matter does not appear in the Specification as accepted.

Patent GB-184429-A (GB)
Abstract: 184,429. Haddan, A. J. H., (National Cash Register Co.). Feb. 26, 1921. Statistical machines; operating by motors. - Perforated-record controlled machines such as are described in Specifications 184,824 and 185,071 for analyzing a detail record sheet or for totalling and for perforating a summary record sheet respectively are provided with control mechanism consisting of an arrangement of switches, electromagnets, and circuits adapted to ensure the closing and opening of the motor and generator circuits and the sequence of operations of the machines in a particular order or under special conditions. In order that the machine may be properly started as an analyzer the following conditions must be satisfied, (1) The manually-set shaft 600 must be adjusted to close the switch contacts 621, 622, (2) the record carriage must be locked in position so as to close the contacts 1052, this being effected by a projection 1053 on an arm 557 actuated by an arm 558 on the shaft 418 of the locking-lever, (3) the record sheet must be adjusted in position to separate roller contacts 568, 569 and thus prevent energization of the electromagnet 1049 and so maintain the contacts 1047 and also the motor M circuit through contacts 1001 closed, (4) the contacts 526, 548 used in conjunction with the special column of ccntrol perforations must be closed, (5) the contacts 1050 must be closed, (which is their normal condition); they are separated by the units totalizer-actuating rack when it receives its maximum movement on the completion of the analyzing operation, and (6) the circuit for the magnet 1037 must be closed in order that the locking- hook 1034 may release the starting-key 1000. With the contacts 526, 548, 1047, and 1052 adjusted as above described the operator depresses a lever 1002, Fig. 5, to energize the motor M of the motor-generator circuit M-G and the circuits through the contacts 1047, 1050, and 622 will maintain magnet 1003 energized. Depression of this key 1000 closes the contacts 1054 and enables a magnet 1030 to be energized which thereupon withdraws a locking-pin 1026 from engagement with a notch 1015 of an arm 1012 and permits the arm to rise to close the contacts 1004 for the main actuating-motor; the clutch for this motor is freed at the same time by an arm 633 mounted on the arm 1012. The machine is stepped as stated above when the contacts 1050 are opened and also if the record sheet is ruptured by reason of the energization of the magnet 1049 and opening of contacts 1047. When operating in conjunction with the totalling &c. machine, (1) the manually-operated shaft is set to open contacts 621, 622 and to close contacts 619, 620, and (2) the circuit of the magnet 1044 is broken to release a second locking-hook 1041 of the starting-key, this being effected by the unperforated record sheet which must be adjusted to open contacts 526, 548. The machine is stopped when the record is completed by means of a switch 968 actuated by a cam 966 controlled by the totalizers zeroizing mechanism.

Title: Improvements in, and connected with, overload-released contact mechanism for automatic electric switches
IPC: H01H71/58
Filed: 1937-07-20
Abstract: 498,376. Electrically released switches ; actuation of switches. CRABTREE & CO., Ltd., J. A. (Schiele Industriewerke) July 20, 1937, Nos. 18532/38 (divided out of 498,325), and 31212/37. [Class 38 (v)] Overload-released contact mechanism for an automatic switch comprises a pair of oppositelyacting springs, one tending to close, the other to open, the contacts, the moving contact being movable together with a trigger by the opening spring while a catch co-operating with the trigger is carried by a part under the influence of the closing spring. Manual means operative on the catch-carrying part is adapted to re-engage the catch and trigger to allow the contacts to close, and an automatic trip is adapted to free the trigger for disengaging the contacts while remaining in the path of the catch or trigger to prevent reclosing of the contacts after operation of the manual means as long as the trip is in the tripping position. The contacts may operate to open the tractive magnet circuit of the automatic switch. In Fig. 1, a single spring 1 is provided with a lower closing part acting in the direction of the arrow P, and with an upper opening part acting in the direction of arrow P<1> and carrying the movable contact 1a. The spring 1 is secured to a fixed support 3 and carries at a point 5 a catch plate 4 which co-operates with a trigger 4a on the upper part to hold the contact la in engagement with contact 6. A trip lever 9 on a pivot 7 is adapted to break the engagement between 4, 4a to permit the upper part of 1 to open the contacts by moving against the back stop 10. Pressure applied to a button 11 re-engages the latch 4, 4a and when the pressure is released the lower part of 1 recloses the contacts provided 9 is inoperative. Two springs interconnected at the point 5 may replace the single spring 1, and the spring or springs may be laminated. A trip-button may act on the trigger 4a. In Fig. 3, the trigger 4a engages a slot in the upper end of a plate 4<1> which is slidable on rivets 5, 8 on plate 4 to release the connection when the trip lever 9 rises. In Figs. 5, 6, the movable contact 12 isr caried on a catch plate 20 on a rod 18 which is slidable in a fixed bracket 19 and urged in the opening direction (shown by the arrow) by a spring 14 bearing at one end against a carrier 16. Rod 18 S slides freely through the carrier, which carries a rod 17 slidable in bracket 19 and plate 20, and carries the closing spring 11a. When the trip lever 9 is rotated, it lifts the end of trigger 15 clear of plate 20 and, since 15 is attached to the carrier 16, the parts assume the Fig. 6 position. When the button 22 is pressed into engagement with pin 20a on carrier 16, the parts 15, 20 re-engage, and when the button 22 is released, the spring 11a moves the carrier to closed position. The switches shown may open, when tripped, the circuit of the holding coil of a circuit-breaker. One Provisional Specification refers to electromagnetic releases, and the other to Specification 498,325.
