Abstract: 1,180,130. Clocks and watches. SUWA SEIKOSHA K.K. May 5, 1967 [May 10, 1966], No.21076/67. Heading G3T. An electric timepiece comprises a balance wheel to which energy for starting and maintaining mechanical oscillations is imparted by a driving coil in a transducer, and an electric circuit for energizing the transducer with electric pulses the width of which, when starting the oscillations, is substantially greater than the width when the oscillations of the balance wheel are maintained in a stable state, said circuit including a detecting coil which detects the speed of the balance wheel. The transducer illustrated in Fig.1 comprises a lever 4 rotatable to and fro by an impulse pin 3 and a balance 1, and a magnet 6 rotatable with the lever 4 in gap in a yoke 11 of ferromagnetic material carrying drive and detecting coils 12, 13 arranged in an electric circuit as illustrated in Fig. 5. This is an astable oscillating circuit which oscillates, when the balance wheel is not oscillating, to generate electric pulses the width of which is dependent upon the charging time of a condenser 26 via a resistor 27, but which width is reduced when the balance wheel attains a predetermined amplitude to generate an induced voltage in the coil 13 which reduces the charging time of the condenser 26. Other circuits are described in which the coils 12, 13 are differently arranged.

Abstract: 304,157. Anode Rubber Co. (England), Ltd., (Anode Rubber Co., Ltd.). Aug. 10, 1927. Latex, coagulating.-Relates to processes for coating or impregnating fabrics or other porous material with rubber or other organic materials deposited from aqueous dispersions, and consists in wetting the fabrics &c., before they are brought into contact with the organic materials effecting the impregnation or coating, with the same dispersion which is to be deposited or with a dispersion of an allied substance. The dispersions may be natural or artificial dispersions of rubber, gutta, balata, or other vegetable resins or artificial dispersions of waste rubber or reclaim. To these dispersions, or to mixtures thereof, dispersions of mineral rubber, rubber substitute. synthetic rubber casein or artificial resins may be added. Compounding ingredients may be added and the rubber &c. may be in a vulcanized condition. In an example a layer of rubber is formed on a metal base in an electrophoretic apparatus, a textile fabric wetted with latex is applied to the rubber layer and the deposition of rubber is continued to embed the fabric. In another example, a dipping mould soaked with coagulating materials is inserted in an aqueous dispersion of reclaimed rubber, a textile product thoroughly wetted with a dispersion of semi-vulcanized rubber is then placed on the rubber layer and the mould is re-inserted in the dispersion to continue the deposit in and on the fabric. Several layers of rubber and fabric may be combined and the layers may be partially dried before the next layer is applied. Layers of varying composition may be built up, and the deposition means may be varied. As an example of several layers, a valve patch for a tyre tube is made in electrophoretic apparatus by forming a rubber layer on a zinc base; applying a fabric ring wetted with latex; continuing the deposition to embed' the fabric; applying a wetted elliptical piece of fabric; and precipitating a final layer of rubber. The articles made may be vulcanized after drying. Specifications 223,189<x>, 245,177, 246,532, 252,673. 253,069, 254,765, 257,885, 296,138, 297,780 and 298,117 are referred to.

Title: Improvements in or relating to electric switches for preventing fire on vehicles after an accident
IPC: H01H35/14
Filed: 1932-07-28
Abstract: 385,897. Gravity and inertia switches. SERMET, L., 19, Rue Vauben, Lyons, France. July 28, 1932, No. 21324. Convention date, Aug. 4, 1931. [Class 38 (v).] A switch for preventing fire on a motor vehicle after collision or excessive tilting comprises a pendulum a which is normally held vertical by its upper end engaging a spring-pressed plunger g. When a collision occurs the pendulum owing to its inertia moves into the dotted line position and a circuit is broken or made. In the form shown a circuit is normally completed through the plunger and the tip of the pendulum which circuit is broken in the dotted line position by the plunger engaging an insulating sleeve m round the pendulum. In a modification, Fig. 2 (not shown), the tip of the pendulum is insulating and the sleeve is conducting, and in the dotted line position the sleeve is wedged between the plunger and a surrounding annular conducting disc, thus closing an earthing circuit. In another modification, Fig. 4, the plunger g is connected by bolts w with a plate y carrying a conducting ring z. When the plunger g is freed from the pendulum after collision, it moves bodily downwards under the action of springs x carrying the ring z out of engagement with conducting segments v.

Title: Improvements in means for expanding metal tubes
IPC: B21D39/10
Filed: 1945-08-21
Abstract: 597,481. Tube expanders. FAIREY AVIATION CO., Ltd., and HACKETT, H. M. Aug. 21, 1945, No. 21356. [Class 83 (iv)] A tool for expanding the ends of tubes comprises rollers g whose axes are laterally inclined to the tool shank a and which are arranged in a cage so that one end can move radially outwards, the radial movement being limited by a sleeve surrounding one end of the rollers, but slidable axially against spring action to de-restrict this outward movement. The cage is formed in two halves c, d and carried between bearings b, e ; the former being journalled in a flange j of the shank and the latter in a nut f screwed to the forward end. The rollers have a slight taper at their forward ends h and their rear ends are covered by an extension sleeve p carried on a sleeve k, which is urged forward by a spring m interposed between it and a collar n fast on shank a. A roller bearing may be interposed between the sleeve and the spring, and coolant may be admitted through an adaptor q to a duct s and passages t extending therefrom into contact with the rollers. The abutting ends of the cage c, d may be joined by pins in one part engaging in blind holes axially arranged in the other part. In operation the rollers screw themselves into the tube which is rotated and eventually the end of the tube abuts the extension sleeve p moving it against the action of spring m to allow the rollers to enter the tube to their full extent. The rotation of the tube is then reversed to remove the tool.

Patent GB-1514002-A (GB)
Title: Speed control circuit
IPC: B60K31/10
Filed: 1976-05-24
Abstract: 1514002 Automatic control of speed DANA CORP 24 May 1976 [22 May 1975] 21387/76 Heading G3R A vehicle speed-control system comprises a first comparator comparing actual and desired road speed signals and controlling a vehicle throttle accordingly, the desired speed signal being formed by a converter from the contents of a counter  counting pulses. The system also includes a second comparator which compares the actual and desired speeds and disables the pulse source when the result is zero, and means to reset the counter and start the pulse source when a command is received from a driver actuated switch. As shown, the switch 35 is opened by the driver when the actual vehicle road speed is at a value to be maintained. This resets counter 22 and sets latch 38 to start the pulse source (oscillator 21). The actual road speed is measured by sensor 26, providing a frequency proportional to speed, that is converted at 27 to a speed dependent voltage. Speed comparator 46 compares this voltage with the converted contents of counter 22, which counts the oscillator pulses. When the result is zero, latch 38 is reset to stop the oscillator, and the count reached in 22 held as the desired speed value. The actual speed signal from 27 also passes via an anticipatory timing circuit 31 to a control comparator 24, where it is compared with the desired speed. Any difference is inverted at 52 and used to control the vehicle throttle value to regulate the road speed to the held desired value. The output of inverter amplifier 52 is fed back to be combined with the actual speed input of comparator 24 in order to vary the gain of amplifier 52 and compensate for non-linearity in the throttle characteristic. If a brake is applied, or the vehicle speed is lower than a pre-set value, amplifier 52 is disconnected from ground, and the automatic control disabled. Details of the system components are given in Figs. 2 and 3 (not shown).
