Title: Improvements in or relating to electric clocks
IPC: G04C3/027
Filed: 1933-10-14
Abstract: 427,178. Electric clocks. BULLE, M. P. FAVRE-, 15, Rue Gambetta, Boulognesur-Seine, France. Oct. 14, 1933, No. 28435. [Class 139] In a clock wherein the pendulum is electrically maintained and drives the hands, the coil 18 is fixed substantially midway on the pendulum 8 and coacts with a permanent magnet 17 having consequent poles S, NN, S to give the maintaining impulse to the pendulum and to regulate its amplitude. The contact device comprises a silver contact pin 45, Fig. 6, and an insulated sheet 46 adjustably bolted on the pendulum which coacts with the known live fork controlling the ratchet wheel driving the hands. The clock may be used as a secondary clock. Pendulums.-The pendulum 8 is of substantially half-round blade design, and rigid in the swinging direction but flexible in a direction at right angles thereto, so that it may be bent until a hole 22 therein engages a hook 23 on the case 1 to fix the pendulum during transport Alternatively, if the pendulum is rigid, a spring blade may be secured to the bottom thereof to coact with the hook 23. The pendulum bob may be replaced by polished concentric discs 14, 15, 16 which may bear advertising matter. As shown in Figs. 7, 8, the axle 31 of the pendulum 8 pivoted at 33, in bearings 34, is also supported by rings 39, 40 hanging from a spring 43 to reduce the friction at the bearings 34.

Title: Improvements in vehicles
IPC: B60G17/027
Filed: 1950-11-23
Abstract: 675,937. Road-vehicle spring-suspensions; adjusting height of body. DEVESON, R. E. Nov. 23, 1950, No. 28625/50. Class 108(ii) The normally-fixed end of a torsion bar 10 is rigid with a ratchet wheel 14 which is non-disengageably engaged by a hydraulically operated rack 15 having similar ratchet teeth to those of the wheel 14, rotation of the ratchet wheel 14 in one direction being avoidably prevented by releasable engagement of a locking block 20 which also has ratchet teeth. The torsion bar 10 is rigid at its other end with the inner end of an arm (not shown) carrying a road wheel at its outer end. The block 20 is urged into engagement with the wheel 14 by springs 21. The blocks 20 may be retracted against the springs by the action of a cam 23 operable by external linkage. The block 20 may thus have one of three positions in which it respectively prevents movement of the wheel in either direction, permits movement in one direction only, or permits movement in both directions. The rack 15 is connected with a piston 17 which may be displaced rightwards (as shown in the Figure) by means of hydraulic pressure. This has the effect of raising the body of the vehicle (which may be a caravan) relative to the wheels. On release of the block 20 by means of the cam 23, the body may be allowed to sink until it rests on the ground, at a rate controlled by the escape of the 'hydraulic fluid.

Title: Improvements in hair waving pads
IPC: A45D4/12
Filed: 1934-10-06
Abstract: 450,084. Hair-waving. BEAUTY UTILITIES, Inc., 48, Spring Street, Newark, New Jersey, U.S.A. Oct. 6, 1934, No. 28694. Addition to 433,351. [Class 131] The socket employed for producing steam from an electrolytic solution as set forth in the parent Specification is modified for use with hair wound on the Croquinole system. The inner electrode 2, Fig. 1, is spaced from upper electrode 8 by a layer 1 of absorbent material stitched to both at 9. The layer 1 overlaps the electrodes to avoid short circuiting. The inner electrode or foil 2 has an overlapping part 2a bent over the layer 1 with a paper insulator 6a having an extension or tongue lying over the foil 8. To provide access to the foil 8 (or an electric connection) the insulator 6a is cut away. The electrode 2 may be perforated as in the parent Specification and a paper insulator 6 may be secured by light waxing and may be perforated in register with the foil 2. In a modification in form, instead of the electrode 2 being bent over endwise as shown, a lateral tongue may be similarly employed. The electrical connections are shown in Fig. 3, Where the Croquinole method to wind a tress 3 on a roller 7 is employed, the rod 7 is mounted in bearings 5 of a holder comprising known pivoted clamping bars 4. An alternating current of low voltage may be used through a step down transformer 11. The absorbent layer may be impregnated with an electrolytic solution including a hair waving solution. The electrodes are advantageously made of lead foil containing a very small amount of tin so as to fuse readily. The heating pad may however serve as a means of heating only and a separate waving sachet may be used therewith.

Title: Improvements in the drying of vinyl chloride by distillation
IPC: C07C17/38
Filed: 1951-12-07
Abstract: In the drying of moist vinyl chloride by distillation, the formation of ice in the apparatus is obviated by adding to the vinyl chloride, particularly in those parts of the apparatus where there is the greatest risk of icing, a liquid oxygen-containing organic compound which is miscible with water. Auxiliary liquids specified are:-methanol, ethanol, ethylene glycol, the monomethyl and monoethyl-ethers of ethylene glycol, acetals, ketones and esters having not more than 4 carbon atoms A polymerization inhibitor may be introduced into the distillation apparatus, in addition to the de-icing liquid.  In an example, moist liquid vinyl chloride (3.5 kgrm.) is cooled in a flask (under pressure of 5 atm.) so that some of the water settles out as separate layer, and is withdrawn. Methanol (100 grms) is added to the vinyl chloride, and it is then distilled.  Methanol containing 0.01 per cent. of hydroquinone is allowed to flow through the condenser.

Title: Improvements in and relating to the covering of walls, floors roofs, ceilings and like surfaces
IPC: E04D5/14
Filed: 1933-10-18
Abstract: A paint for use in securing to surfaces sheets of flexible bitumen-surfaced fibrous material comprises bitumen, a substantially non-volatile flux for the bitumen, and a volatile vehicle for the bitumen, the vehicle being adapted to deposit fluxed bitumen in adhesive condition on the surface after evaporation of the vehicle. The paint may comprise 50 per cent of hard oxidized bitumen, 45 per cent of white spirit or solvent naphtha, and 5 per cent of a flux, such as creosote.  An alternative composition consists of 85 per cent of the bituminous compound, 29 per cent of white spirit or solvent naphtha, and 6 per cent of creosote.  The paint may be applied in one or more coats until a deposit of fluxed bitumen in tacky condition is obtained.  If desired, successive coats of the paint may contain higher percentages of bituminous compound, commencing with a paint which is low in bitumen content so that the deposit penetrates into the wood or other surface being coated.  If the bituminous layer of a surface covered as described above becomes hard due to exposure, it may be rejuvenated by painting the exposed surface of the fibrous material with a liquid bituminous flux which penetrates the fibrous material.  As an example, if the attaching paint includes creosote as flux, then the surface of the fibrous material may be coated with a mixture of white spirit and creosote.

Title: Remote-controlled motor-propelled transport car for the transport of motors during assembly and testing and an assembly and testing system incorporating the transport car
IPC: B62D65/10
Filed: 1975-07-09
Abstract: 1495319 Transport car for motors being assembled and tested VOLVO AB 9 July 1975 [11 July 1974] 28819/75 Heading B8H A transport car, used in a system for the assembly and testing of motors transports motor parts or complete motors alonga path to successive working stations under guidance of signals received from a signal transmitting arrangement which operates along the path, comprises a motor fixture on a plate 25 attached to base frame (10), Fig. 1 (not shown), of the car and carrying an index plate 31 arranged to be rotated by a shaft 32 journalled in a hub 33. Two telescopic devices 52 are arranged one either side (to the front and rear as illustrated) of a bearing housing 43, which they support by plates 55 joining the devices 52, which are themselves mounted on the plate 31. A moderating element 38 comprising two plates 39 with rubber cushions 40 between is arranged centrally on the plate 31. The upper plate 39 supports a threaded casing 41 through which a screw 42 extends. The screw 42 is journalled at its upper end in a part 44 connected to the bearing housing 43. The screw 42 can be rotated by a tool (not shown) engaging hexagonal portion 47. In the position shown a rigid connection is established between the bearing housing 43 and the index plate 31 since a casing 62 connected to the part 44 rests on the upper surface of casing 41 and plate 59 of outer telescopic tube 54 rests against the upper edge of inner telescopic tube 53. The motor M, mounted at 50 on a plate 49, is thus rigidly connected to the car in an assembly position. Turning of the screw 42 counterclockwise initially moves the screw 42 upwards until upper part of bearing 46 abuts the bottom side 70 whereupon continued turning lifts the bearing housing 43 and all attached parts until a plate 71 at the lower end of the screw 42 abuts the bottom side of the casing 41. Simultaneously the outer telescopic tubes 54 are lifted, pins 60 being disengaged from bushings 61 and the bottom edge of the tubes 54 moved above ring 58. The tubes 54 are now only guided on casings 57 carried by flexible rings 56. This provides a test position for the motor since it now has a resilient connection with the car so that no damaging vibrations may be transmitted from the motor to damage electrical equipment in the car.

Title: Improvements in and relating to vending machines incorporating locking systems
IPC: G07F7/12
Filed: 1961-08-10
Abstract: 995,621. Dispensing petrol; vending machines. H. A. RAUSING. Aug. 10, 1961 [Aug. 15, 1960], No. 28943/61. Heading A4T. [Also in Division G4] A vending machine such as a petrol pump or a machine providing a service is operated by a customer inserting in the machine a key means, e.g. a punched card, having a characteristic signature, each key signature containing several index elements divided into two groups having the same number of elements and between which groups there is for all the key means capable of operating the vending or other machine a common conversion code, the vending or other machine having means for sensing the signature of an inserted key means and comparing in accordance with the conversion code, one index group with the other in order to prevent operation of the vending machine by illegitimate key means. The machine may also compare a signature with recorded signatures stored in machine which haves become invalid. In a described embodiment applied to a petrol pump the token consists of a punched card having two groups of seven holes, one set representing an account number and the second a number related to the first by a number characteristic of the pump. The card is placed on a platform 6 and moved inwardly by a handle 11 until pawl 15 engages the first tooth of an arm 8 attached to the lever. In this position the first holes in the two groups are sensed by photo-electric means comprising photo-diodes F10-F19 and F20-F29 which are connected to relays operated only by the current provided when two photo-diodes are simultaneously actuated. If the token is an illegitimate token the detent 15 will be lifted as each relay corresponding to the seven pairs of holes are actuated allowing the lever 11 to move inwardly until a switch BK is closed. Before the pump can be operated either the account number or the check number is compared photo-electrically with a black-list of numbers recorded on a film strip contained in a unit SM. If a number of the presented token is not on the blacklist, petrol can now be dispensed by lifting the filling nozzle of the pump off a hook, the quantity and quality of the petrol dispensed, the account number, petrol pump number and the date being recorded on a punched tape. Completion of successive recording operations releases a pawl 16, which when engaged with the arm 8 prevents the return of the lever 11 to its oriignal position, so that the lever 11 is released step-by-step as the required information is recorded. Illegitimate tokens are confiscated by the checking unit and in a modification when the tokens can have a cash value the tokens are also confiscated by the checking unit. In a modified form of token the index characteristic may be formed of magnetized slots which are sensed electromagnetically.
