Title: Improvements in or relating to mechanism for controlling the movement of the indicator needle of a dial gauge
IPC: G01B3/22
Filed: 1942-09-14
Abstract: 561,168. Dial gauges. WOODALL, F. J. Sept. 14, 1942, No. 12932. [Classes 106 (ii) and 106 (iv)] The needle of a dial gauge is controlled by means of a pivoted abutment member or cam associated with the needle and a pin element carried by the displaceable element of the gauge, the needle and pin element having springs which act to press the pin element against a contact face of the abutment member. As shown in Fig. 1, the casing 1, which is adapted for attachment to the swinging arm of a stand, has a depending part 9 housing a sleeve 8 formed with cheeks 11, Figs. 3 and 4, through which pass bearing pins 12 engaging bosses in the end flanges 14 of a semicircular cam-shaft 15. Mounted on one of the bosses is an indicating needle 7 to which is attached one end of a control spring 18. The needle 7 is formed with an arcuate slot 22 in which is a set screw to limit the movement. The plunger 26, Figs. 4 and 7, which is to engage the workpiece is formed at its upper end with a bracket 25 which carries an adjustable bush 24 with a pin 23 engaging the cam 15. The upward movement of the plunger acts against a tension spring 30 that is stronger than the spring 18. In the upward movement the pin 23 will free the cam 15 which will follow under the action of the loading spring 18. In a downward movement of the plunger, the pin 23 will cause the cam 15 to rotate in the opposite direction. In a modified form, Fig. 10, the indicating needle is mounted on a spigot pin 34 and carries a pin 36 (not shown) for co-operation with the edge 37 of a lever arm 38 connected to the cam-shaft 15. The lower end of the engaging pin 23 may be formed with a blade edge instead of a point.

Title: Target apparatus
IPC: F41J5/04
Filed: 1964-03-31
Abstract: 1,066,491. Targets. L. C. KNIGHT. March 31, 1964 [March 27, 1963; Jan. 30, 1964], No. 13189/64. Heading F3X. Target apparatus includes a target movable from an operative to an inoperative position, target moving means for moving the target in response to received electrical signals, manually operable target control means for initiating the signal and relaying means for relaying the signal from the target control means to the target moving means. As described a plurality of targets are movable by electric motors in response to electrical signals transmitted by cable from a relay unit which is provided with means to receive and process radio signal pulses from a command console having manually operable push-button control action producing appropriate radio signal pulses. The targets are provided with hit detection means so that an electrical impulse is transmitted to a bi-stable memory multi-switch in the relay unit and at the same time operates the target moving means to move the target from its operative to inoperative position. The relay unit has a master scanning unit which scans the memory multiswitch and generates appropriate radio signal pulses corresponding to the memory multiswitch indication of hit detection input pulses, the radio signal pulses being transmitted to and received by the command console wherein a slave scanner is synchronized with the master scanner and reproduces the hit detection input pulses for operation of hit recording means, e.g. counters. The target moving means may have a plurality of electrically operated detonators operable by the command console through the two-way radio link to simulate retaliatory fire. A switch operates to prevent the detonator blast registering as a hit. A " hold " signal may be transmitted by the command console which prevents the targets from falling due to a hit and thus permits rapid fire at the targets. The command console may be replaced by a portable control unit with a one-way radio link with the individual target receivers; however, registration of hits is not possible with this arrangement. A night shoot control apparatus may be provided so that a white lamp lights at the same time as detonation and a red lamp lights on registration of a hit. The targets are preferably of thick waterproof plywood backed by light canvas or calico and faced with canvas reinforced rubber on which is applied etching paint to form a desired pattern. The shot damage of the targets may be repaired by the application of special adhesive and sawdust.

Title: Improvements relating to fuel supply arrangements in internal combustion engine
IPC: F02M69/52
Filed: 1958-04-30
Abstract: 834,970. Fuel supply arrangements. GENERAL MOTORS CORPORATION. April 30, 1958 [May 9, 1957], No. 13726/58. Classes 7(3) and 7(6) An engine is supplied with fuel under normal operating conditions by an injector pump whose output varies with engine speed and which is connected to the output side of a transfer pump a movable valve member of a fuel metering valve controls the rate of fuel supply to the engine in accordance with the signal produced by air flow through a venturi in the engine air induction system and the valve member is moved under certain operating conditions from a position in which all the fuel that is supplied to the engine is delivered by the injector pump to a position in which fuel delivered by the transfer pump by-passes the injector pump and is supplied direct to the engine. As shown fuel outlet passages 64 are formed in the casing 34 and either communicate with a fuel manifold or as shown with the individual cylinder supply conduits 30. A set of radial passages 110 in the movable valve member 90 are adapted to register with annular port 84 but under normal operating conditions valve member 90 is maintained in the upper portion of the sleeve 38 whereby the radial passages 110 are out of registry with the annular sleeve port 84. Further the lower end 112 of the valve member coacts with the radial passages 66 to determine the quantity of fuel which is by-passed to the counterbore 68 and hence back to the reservoir 50. As air flow through the venturi 16 increases the lower end 112 of the valve member 90 increasingly reduces the quantity of fuel by-passed and hence increases the quantity of fuel delivered to the individual cylinder conduits 30. When the output of the main fuel supply pump 48 is very low as is the case when the engine is cranked preliminary to starting or under very low engine speed operation particularly when the engine is cold, the pressure within the sleeve 38 is very low. In this case the cranking vacuum acting on the diaphragm 26 is adapted to move the slidable valve member 90 downwardly to seat on stud 92 fully closing radial ports 66 and moving the radial passages 110 into registry with the annular port 84 Fuel from the make up pump 80 is then supplied to the interior of the sleeve 38 and thereby delivered to the outlet passage 64 and cylinder supply conduits 30. The force exerted on the top of the plunger 90 by the modulated vacuum signal imposed on the control diaphragm 26 varies with ambient temperature. Thus the plunger is not necessarily pushed down to seat on stud 92 to bring the passages 110 fully into register with the port 84. This permits the correct amount of fuel to enter the engine for starting at all temperatures. Fuel can thus be supplied from the transfer pump 80 when the injector pump 48 is being driven at speeds inadequate to supply the necessary quantity of fuel. The choke valve 20 is adapted to be controlled in response to engine temperature induction air flow and load.
