Patent GB-1434969-A (GB)
Title: Moulding apparatus
IPC: B22C9/06
Filed: 1973-12-07
Abstract: 1434969 Pressure casting apparatus ETABS A VOISIN 7 Dec 1973 [15 Dec 1972] 56753/73 Heading B3F A low pressure casting apparatus comprises a mould having a base plate 6, a tank 8 for holding molten metal, the said tank being attached to the base plate 6, and a plurality of tubes 18 providing communication between the interior of the tank and the mould cavity. The mould may comprise a plurality of parts 2, 3 and 4 and may be provided with sand cores 5 having vents 30. The tank 8 is provided with a cover 7 which is fastened to the base plate 6 at particular points only so that a gap 6a in which a cooling fluid may be circulated is left between the two. Heating elements (12) may be provided in the cover 7 and walls of the tank. Molten metal may be introduced into the tank 8 through a funnel 22 which can be closed by a sliding valve 23. Ejector rods 15 for the casting pass through the tank 8 and are surrounded by a housing 19 to prevent contact between them and the metal within the tank. The casting operation may be controlled by means of a level sensor 27 which closes the valve 23 when the level of metal in the tank reaches the required height and initiates a supply of air under pressure to the interior of the tank to force the metal up the tubes 18 into the mould. After solidification of the metal in the mould, the molten metal in the tubes 18 may be drawn back into the tank 8 by connecting the interior of the latter to a vacuum source. The tank 8 is refilled after each casting operation since nearly all the metal contained therein is used up in each such operation. In an embodiment the mould defines a plurality of separate cavities, Fig. 5 (not shown).
Patent GB-572903-A (GB)
Abstract: 572,903. Seismic recording. SHELL DEVELOPMENT CO. Aug. 10, 1943, No. 12902. Convention date, Aug. 31, 1942. [Class 106 (iv)] A seismograph system comprises in circuit a detector adapted to generate electrical impulses, an amplifier and a recorder, a variable resistance shunting the circuit between the detector and the amplifier, time-responsive means for changing the value of the resistance during the recording of said impulses, and adjustable control means for varying the rate of change of said resistance. In seismic exploration, the first shock from the detonation is very much greater than the waves reflected from the lower strata, and the invention is concerned with varying the sensitivity of the recording so that the less intense waves can be recorded easily and the correct deduction made. In Fig. 1, impulses from the detector 1 pass to an amplifier 30 and a recorder 40, the conductors 2, 3 being shunted by a resistance 5 partly immersed in a conducting liquid such as mercury. The level of the mercury is controlled by the depth to which a buoyant cylinder 12 is immersed. At the first shock, an amplifier circuit 19 also shunted across the conductors 2, 3 energizes a magnet 18 to withdraw a detent 16 from the cylinder 12 which rises to lower the level of the mercury and to increase the shunt resistance 5, whereby the system is rendered more sensitive to subsequent waves. The rate at which the sensitivity is increased can be retarded by control slides 14 impeding the flow of the mercury. While the waves have considerable amplitude, an amplifier 35 and rectifier 36, shunted between the amplifier 30 and recorder 40, energize a further magnet 22 to impose a brake 20 on the cylinder, the brake releasing as the strength of the current falls. In Fig. 3, the brake 20 is replaced by an air valve 51. A number of detectors can be arranged in circuit with shunt resistances in a common bath to form a multi-channel system (Fig. 4, not shown).

Filed: 1971-12-10
Abstract: 1379587 Air motor speed control BOWLES FLUIDICS CORP 10 Dec 1971 [17 Dec 1970] 57593/71 Heading G3P An air motor 10 supplied by valve 11 is maintained at constant speed regardless of load by adjusting valve 11 using a signal 15 from a bridge circuit 13 including a restrictor 23 in series with the motor and a parallel branch fitted with series restrictors 19, 21 of which the latter is permanently choked. The pressures at 20, 24 downstream of restrictors 19, 23 are compared in fluidic amplifier 25 from which signal 15 is obtained. The bridge circuit thus adjusts the valve 11 to maintain the pressures at 20, 24 equal, the pressure at 24 varying according to the load on the motor but, due to restrictor 21 being choked, the volume of air delivered to the motor remaining constant. In a modification, amplifier 25 is replaced by a bellows operated leak-off valve controlling the supply valve optionally through one or more fluidic amplifiers. Variation of the set speed is obtained by adjusting restrictor 23.

Abstract: 1,255,618. Fastener driving tool. FASTENER CORP. 20 Dec., 1968, No. 60629/68. Heading B4C. [Also in Division B8] A nail driving tool 24 includes a reciprocating driver 26 for the nails which reciprocates within a drive track 28 which extends from the end of a pneumatic cylinder assembly 30. A carrier (see Division B8) which carries a row of nails is advanced into the drive track 28 from a rearwardly extending magazine 32 by a feed member which has a lug 44A engageable with openings 20 in a web of the carrier and the carrier after the nails have been removed by the driver 26 passes into a guide 41 which has an opening 28b into the drive track. The guide 41 includes a U- shaped portion having a pair of convergent spaced apart side walls 41a and 41b which fold upper and lower segments 14 which carry the nails downwardly towards alignment with the web 10a of the carrier; this folding action is stated to weaken the carrier against lateral bending and more readily permits twisting of the protruding end portions of the carrier to facilitate tearing of the carrier. The lug 44a is carried by a piston 44 mounted in the cylinder 42a which is moved by pressurized fluid in one direction returned by a spring 50 or vice versa. Return movement of the carrier is prevented by a back-up lug 51 which engages the nails in succession. Return movement of the lug 44a depresses the web of the carrier transversely to permit the lug to pass from one opening 20 to the next.
