Title: Apparatus for indicating the flight of a captive ball
IPC: A63B69/00
Filed: 1934-03-09
Abstract: 434,536. Golf-practising appliances. STRUCKMAN, E., 97, Copse Hill, Wimbledon, London. March 9, 1934, No. 7541. [Class 132 (ii)] [See also Group XXXVIII] A device adapted to measure the extent and direction of the probable flight of a captive golf ball is connected to electrical indicating means for giving a visual indication on a screen of the probable flight of the ball when struck. The invention is described as applied to a golf-practising appliance 4, Fig. 2, of the kind described in Specification 313,196, [Class 132 (ii)], wherein the extent of flight of a captive ball is measured by the angle of rotation of a drum 18, Fig. 1, around which the tethering cord is wound, while the direction of flight is indicated by a pointer 6. According to the invention, the measuring device is connected to an electrical indicating device comprising a number of lamps 10 situated behind a screen 1 carrying a representation of one " hole " of a golf course. The connections between the indicator and the measuring device are such that lamps are illuminated in succession to indicate the probable flight of the ball over the course represented on the screen, the lamp which remains alight at the end of an operation indicating the position at which the ball comes to rest. The lamp which is illuminated at any moment is selected, as to its vertical column, by the movement of the pointer 6 over contacts 5 and, as to its horizontal row, by the movement of contacts 17 on the drum 18 relative to a contact 19. For this purpose, lamps in each column are connected by leads 11 to a mercury switch 12 that is connected to one side of the supply and is mounted on a tipping platform 14 associated with a relay 8 selected for energization by the pointer 6. Lamps in each row are connected by common leads 16 to the contacts 17, contact 19 being connected to the other side of the supply. In order to retard the apparent movement of the ball over the screen, the contact 19 is mounted on a rotor 20 driven by a spring motor through an angle proportional to the rotation of the drum but at a lower speed, the spring of the motor being wound at each operation to an extent proportional to the movement of the drum. The contact is connected to the rotor through a ratchet device which enables the contact to be restored to normal position upon the return of the drum. A main switch 21 is closed immediately upon the rotation of the drum from normal position.

Filed: 1935-03-12
Abstract: 451,870. Reciprocating machines. GOLDSCHMIDT, R., 84, Hillfield Court, Hampstead, London. March 12, 1935, No. 7729. [Class 35] [See also Group XIV] An electrical impact motor for vibrating the head of a razor is housed in a casing 1 which, together with a battery 16, is contained in the handle of the razor. The coils 11, 12 of the motor are wound on a core 2 which carries projections 6, 7 and is mounted on pivots at 3. Normally a fixed contact 10 on the casing and a spring-pressed contact 9 are in contact and remain so during slow vibrations of the armature. When a current passes the ends 2<a> of the core are magnetized and are attracted towards the sides of the casing 1 ; a blow is struck on a hard projection 4, the shock of which causes a momentary gap between the contacts, the circuit is broken, the core flies back under the influence of the elasticity of the parts, contact is made again and so continuous small vibrations are set up. Alternatively vibrations are obtained by providing slack at the pivot 3. In a modified arrangement of the contacts both are yieldingly mounted. Specification 450,687 is referred to.

A liquid delivery recorder, used to record data relating to the delivery of a fuel such as oil from a road tanker, comprises a liquid delivery meter and a time stamp means which stamps the times that dispensing starts and finishes on a customer's ticket. As described, the vehicle driver inserts a ticket and copy with interleaved carbon in a slot 4, rotates a handle 19 causing a pin 23 to pierce the ticket so that it cannot be removed without further damage, and also closes a switch 30 so that a solenoid 18 is energized to press a gallonage counter 29 downwardly so that the initial reading of the liquid meter is recorded on the ticket at A. When dispensing commences a flow switch 7 is closed so that solenoid 11 is energized to stamp the initial time on the ticket at B. A solenoid 12 then operates to shift the stamping wheels 15, 16 together with their associated solenoids &c. in a position in which the time and gallonage are recorded in response to a further rotation of the handle 19 when delivery is complete. The pin 23 can only be raised after the latter stamping has been completed. In a modification (Fig. 3 not shown) the solenoid 11 moves the slot 4 and the locking mechanism and pin 23 horizontally, while the stamping wheels remain stationary.

Abstract: 730,186. Fluid-actuated valves. DUNLOP RUBBER CO., Ltd., TREVASKIS, H. W., and DUNLOP RIM & WHEEL CO., Ltd. March 10, 1953 [April 1, 1952], No. 8231/52. Class 135. [Also in Group XXXIII] The control and valve mechanisms used in a feel simulator for aircraft powered controls (see Group XXXIII) are shown in Fig. 2 wherein the chamber 21 is connected by port 19 to the aircraft pitot head. The diaphragm 21 communicates the force acting on it to lever 29 through the pointed end 28 of a rod 24 fast with the diaphragm. Lever 29 abuts two rollers 30, 31 slidable laterally in a slot in their carriage 32, which rollers 30, 31 slidable laterally in a slot in their carriage 32, which rollers transmit force from lever 29 to the end 38b of a lever 38 pivoted at end 38a. By rotating the knob 35, carriage 32 moves parallel to the levers, and varies the mechanical advantage between them. In the valve mechanism 4, the inlet from a source of fluid-pressure 5 is controlled by ball 44 mounted in a slider 50, an extension of which (see Fig. 3, not shown) abuts the exhaust valve seat 48 slidable in a channel between the exhaust chamber 41 and the inlet chamber 42. Slider 50 is biased by spring 46 to close the inlet, the bias being adjustable by screw 52. When lever 38 is rocked, it depresses plunger 54 and thus the exhaust valve 53, its seat 48 and slider 50, opening the inlet valve. Fluid pressure in the chamber will increase until it is sufficient to raise exhaust valve 53 against the force of lever 38, enabling the inlet valve to close. When pressure from the pitot head is reduced, the exhaust valve is unseated and liquid flows to the reservoir, reducing the pressure until the exhaust valve closes again. A permanent spring- bias acts on lever 38. The channel 7 connects the pressure chamber with a ram and cylinder mechanism providing the feel.
