Title: Pumps and dispensers
IPC: B05B1/34
Filed: 1970-12-08
Abstract: 1315866 Spray producers AFA CORP OF FLORIDA 8 Dec 1970 [7 Aug 1970] 57165/70 Heading B2F [Also in Division Fl] In a liquid dispensing apparatus wherein a pump 5 draws liquid from a container through a tube 13 and one-way valve 24 and delivers liquid through a duct 26, a one-way outlet valve 35 and an orifice 31 in a nozzle 30, the position of the nozzle 30 is adjustable between a position in which the one-way outlet valve 35 works normally to deliver liquid through orifice 31 and a position in which the one-way outlet valve 35 is held permanently closed to prevent operation of the pump and leakage from the container during transportation. The one-way outlet valve 35 comprises an externally ribbed sleeve which is closed at one end 37 and at the other end has a valve face 46 engageable with a valve seat 47 formed on the pump body 1. During normal operation of the dispensing apparatus the valve face 46 abuts the valve seat 47 during the suction stroke of the pump and during the discharge stroke of the pump the valve sleeve moves axially until a shoulder 43 thereon abuts a shoulder 51 on a surrounding sleeve 27. Liquid is thus permitted to flow from the duct 26 through a space between the valve face 46 and the valve seat 47 and through ducts 43, 42, 39, 38 to the orifice 31. When the dispensing apparatus is not in use a cap 29 is screwed further onto the pump body 1 and thus moves the nozzle 30 and valve sleeve 35 right to hold the valve face 46 in engagement with the valve seat 47. To prevent discharge of liquid from the pump. Tangential ducts 39 are formed in the end face 37 of the valve element and lead into a swirl chamber 38 adjacent the orifice 31. If the nozzle 30 is positioned so that during pump discharge the end face 40 of the valve element 35 abuts the nozzle the liquid passes through the ducts 39 and swirl chamber 38 to leave the orifice 31 as a spray but if the nozzle is adjusted so that a space exists between the end face 40 and the nozzle the liquid leaves the orifice as a jet. An air intake is provided into the container through ducts (21, 22) in a cap 14 and a flange 12 of the inlet valve 24. A conical rubber seal 18 permits the air to enter the container but prevents liquid leaving the container through the air intake ducts.

Title: Improvements in or relating to compacting machines
Inventor: MARSHALL ALEC FRANK
IPC: B22F3/03
Filed: 1968-12-13
Abstract: 1,242,259. Moulding powders. BIRMING- HAM SMALL ARMS CO. Ltd. 2 Jan., 1970 [13 Dec., 1968], No. 59300/68. Heading B5A. A machine for the production of compacts of metal or other powder having two or more sections of different thickness in the line of pressure includes an upper punch 7 fixed to a ram of the machine, an axially movable die 1 defining the outer periphery of the compact, a fixed lower punch 3 and a vertically movable punch 2 disposed within the die, the punch 2 being movable from an upper pre-compacting position to a lower final position, and being supported by a piston 8 within a stationary cylinder 9 and slidable about the punch 3. An axially adjustable core rod 4 is provided. The piston 8 is held in its uppermost position by pressure fluid in the chamber 11 and the face 12 of the cylinder defines the lowermost position of the piston forced down during compaction. The movement of the piston 8 and punch 2 may be assisted by fluid pressure applied to the upper face of a shoulder 13 by means of a piston 18 in a cylinder 17 and forced down by a plunger 21 connected to the ram 20. A resilient buffer 22 is located between the parts 21 and 23. The area of piston 18 is less than that of the shoulder 13 and initially the piston 8 moves slower than the ram 20; as the powder is compressed between the punches 2 and 7 both move at the same speed and the buffer 22 expands. Alternatively, the fluid pressure on the piston 8 is applied from a separate source controlled by a valve operated by the ram movement. In a further embodiment initial movement of the punch 2 causes the piston 8 to move downwardly exposing a shoulder thereof to high pressure fluid; alternatively high pressure fluid may be applied to the said shoulder without the initial downward movement by the punch.

Abstract: 1316770 Exposure control systems POLAROID CORP 31 Dec 1970 [2 Jan 1970] 62028/70 Heading G2A In a camera for use with the type of cassette disclosed in Specification 1314609, having a temperature-responsive impedance 62 mounted on it for co-operation with an exposure control system in the camera, the system includes means for detecting the presence or the absence of the said impedance, and, if it is absent, introducing a compensating impedance into the control circuit. As shown, the impedance 62 has terminal portions 61, 63 which co-operate with contacts 58, 60 mounted on a spring member 64 secured to the camera body. Two leaf switch members 130, 134 are provided, and member 130 is permanently connected to contact 60 by means of a line 140. When an impedance member 62 is present on the cassette, then as the cassette is inserted into the camera the member 62 engages and pushes the flexible end of switch 134 into the position shown in broken lines in Fig.3, so that contact between members 130 and 134 is broken and the impedance 62 is in circuit. If the impedance is not present members 130 and 134 remain in contact, so that a compensating impedance mounted between member 134 and contact 58 (see Fig. 4) is brought into the circuit. In this way a correct exposure may still be obtained. Instead of the mechanical arrangement of Figs. 3 and 4, the sensing of the presence or absence of the impedance 62, and the introduction of the compensating impedance, may be effected by electrical circuitry forming part of the control circuit itself Fig. 5, (not shown).
