Title: Improvements in moulding presses for finely divided substances
IPC: B30B15/30
Filed: 1936-02-20
Abstract: 475,487. Moulding-presses for pulverulent &c. substances. PORTER, G. S. Feb. 20, 1936, No. 5124. [Class 87 (ii)] Moulding-presses for finely-divided substances such as high-explosive known as tetryl, comprise a mould b having a relatively deep bore and a plunger e, both of which are positively reciprocated by means providing relative synchronous movement during moulding, whereby they are always in continuous movement in one direction during the period of actual pressure and so as to cause a continuous movement of discharge of the material from the mould during pressing. The mould b is reciprocated in a fixed casing a<1> by rods b<3> and eccentrics b<5> on a main shaft c. The casing a<1> is slotted for trunnions b<2>. The plunger e is carried on a head e<1> working in a sleeve e<20> on a fixed bracket and is actuated by a cam e4 on the shaft c. The bottom of the mould cavity is formed by a mandril d<1> having an enlarged portion d<2> and a head d<3> supported by levers pivoted to the frame and counterbalanced by weights so as to take up any overload of pressure. The mould has a central bore with a flared top. A core-rod f may be provided and the plunger may be formed with a bore e<5> for its reception. The core-rod is reciprocated by levers f<1>, f<2> and a spring- loaded rod f<3> actuated by a cam f<6> on the shaft c. The arrangement is such that the mould begins to ascend before the plunger begins to descend and reaches a feeding position. As the plunger moves down and exerts pressure, the mould descends and continues to descend while the plunger completes compression and rises, the article being finally exposed for removal. The plunger, being cam-operated, is lifted clear of the mould and held at rest by a balance weight on a lever pivoted to the top end of the head e<1> and fulcrumed to a link pivoted on the frame. The article is removed, when the mould is lowered, by a reciprocating brush h on a spring-loaded rod h<1>, pivoted at h<2> and actuated by a trip finger h<7> on one of the eccentrics b<5>. Lubricant may be supplied to a bore g<1> in the mandril d<1>, there being felt pads and passages arranged at the top of the mandril and a gland g<4> and packing at the bottom. Drain channels g<9> may be provided. The material is fed from a hopper j provided with baffles to a port leading to a casing j<4> wherein is reciprocated a feed-slide k having an adjustable measuring cavity k<1>, Fig. 10, adapted to register with a port j<5> leading to a shoot l. A funnel 11 is suspended from the sleeve e<20> at the end of the shoot. The feedslide is reciprocated from a cam m having notches for vibrating or jarring the slide. In order to adjust the size of the cavity k<1>, one of its sides is constituted by an angular slidable member n<12> having a guide block n5 engaged by a screw-thread on a rod n<3> which connects the slide with jaws n<1> and an operating lever m<4>. By rotating the rod n<3>, as by a bar in a hole n<11>, the position of the member n<12> can be adjusted.

Title: Control circuit
Inventor: WERNSING EGON
IPC: G05B19/23
Filed: 1967-02-03
Abstract: 1,166,916. Programmed control of position. STARKSTROM-ANLAGENBAU KARL-MARXSTADT VEB. Feb. 3, 1967, No. 5246/67. Heading G3N. An arrangement for the control of a tool alternatively by reference or chain dimension signals comprises a programme input unit 1, a first forward and backward counter 2, a control system for moving the tool 10, an incremental measuring system 9 for feeding pulses to the first counter and to a second forward and backward counter 3, a first gate circuit 4 connected to the second counter and controlled by the programme unit 1 so that when it is opened it feeds the count of the second counter 3 into a third counter 5, a control member for blocking the system and opening a second gate circuit when there is a count in a third counter 5, and a pulse emitter 8 for feeding pulses into first and third counters to count them in reverse when the second gate 7 is open. Signals representative of the distance to be moved are fed from the programme input 1 into a counter 2 hence system 10 moves the tool and a distance measuring system 9 pulses the counter 2 back to zero whereupon movement of the tool is stopped. The system 9 also counts a like number of pulses into counter 3. If unit 1 feeds a further signal into the counter 2 the tool is moved to a second position according to the number of additional pulses, but if the signal is related to the initial position of the tool then unit 1 opens a gate 4 and allows the count in counter 3 to be fed to the counter 5 while the count in 3 is retained. Counter 5 then causes a member 6 to emit a signal to the system 10 which prevents movement of the tool. Member 6 also emits a signal to the gate circuit 7 allowing pulses emitted by a pulse emitter 8 to pass through the gate 7 to counters 2, 5. When counter 5 is counted backwards to zero, a member 6 no longer emits signals so that the gate 7 is again blocked and the system 10 is then released permitting the tool to move until the system 9 has counted the counter 2 back to zero and counter 3 forwards by a corresponding amount. If the second position is closer to the initial position than the first position then counter 2 will have to be counted negatively by the pulse emitter 8 which will cause the system 10 to move the tool in the reverse direction.
