Abstract: 980,679. Selective signalling systems. VENNER Ltd. March 23, 1961 [April 29, 1960, No. 15221/60. Heading G4H. In a typewriter programming unit, operation of one of keys K 1 -K n  causes a selector to select and store e.g. on a magnetic tape or drum, a wax cylinder or disc or a punched card or tape, a signal corresponding to the key operated, and the selector may be made responsive to signals thus stored to operate the appropriate ones of a plurality of solenoids 26 so as to type out the stored information. In the embodiment described the signals are groups of pulses, operation of a key K opens gate 12, and clock pulses from oscillator 13 are supplied to a counter 3 and to a recording head 17. Counter 3 marks its output leads 2 in succession until the lead connected to the operated key is marked, whereupon gate 12 is closed, and after a delay introduced by unit 32 relay 30 is operated to energize the corresponding solenoid 26 to obtain a check on the signals recorded. To reproduce recorded information, switches S 1 a-S 1 d are moved to position P, and each group of pulses from pickup head 18 is supplied to counter 3. The first pulse of a group opens gate 12 over S 1 d, allowing clock pulses to reach auxiliary counter 36 over S 1 c. At the end of a pulse group counter 3 marks the appropriate lead by relay 30 is not operated until counter 36 is filled (after a time corresponding to the maximum number of pulses in a group), and the appropriate, solenoid 26 is energized.

Title: Sand molding machines
IPC: B22C15/20
Filed: 1942-10-30
Abstract: 565,861. Moulding-machines. DEHN, F. B. (Beardsley & Piper Co.). Oct. 30, 1942, No. 15299. [Class 83 (i)] [Also in Groups XXIX and XXX] A moulding-machine, of the type in which a sand projector A is carried on an arm C which is movably mounted on a pivoted jib B, is provided with an operator's support K and manually operable control means l for the arm- and jib-shifting means, all mounted on the arm C near its free end. Sand is fed by a belt M driven by a motor m to a belt m<3> and the projector A, driven by a motor a<2>. Power for moving the arm and jib are supplied by oil delivered by a constant-pressure pump 69 driven by a motor 68. A control lever L is universally pivoted in a box k<1> so that it can move a rod 144, Fig. 5, axially or oscillate it, the axial movement being transmitted by linkwork in the arm and jib to operate a pilot valve G and the oscillation, by a pinion, rack and linkwork, to operate a valve H, both valves being carried by the jib B. When the pilot valve G is oscillated from its normal mid-position shown in Fig. 23, it allows the fluid in one or other of the chambers 106, Fig. 17, of a valve F to be gradually discharged by pipe 88 or 89, passage 118, Fig. 23, and pipes 115, 81 leading to the sump 66, thereby allowing a small constant oil supply through passages 100, 107, 113, 108, Fig. 17, to produce a relatively higher pressure in the other chamber 106 and thus move the plunger f from its normal midposition and admit pressure oil from the pipe 82 to pipes 84, 85 and cylinders E, E<1>, thereby moving racks e3, e4 to turn the pinion e<2> and the jib, which is connected thereto, in one direction or the other. When the valve H, Fig. 5, is moved from its normal mid-position, it supplies oil to one end or the other of a cylinder a<5>, thereby moving a rack a' to turn a pinion 65 and the arm C which is connected thereto. A valve I, Fig. 1, can also be moved from its normal mid-position by an electric motor 130 controlled by switches 135 whereby oil is supplied to or exhausted from the bottom of a cylinder 54, the piston of which is connected by links 60 to a link D, whereby it can be turned about horizontal pivots 49 to raise or lower the jib, which is kept horizontal by parallel links D, 51, and the projector. The plunger f, Fig. 17, is shaped to open the exhaust passages slowly and the movements are also cushioned by arranging small byepass valves 84a and J, Fig. 5, between the supply and exhaust pipes. When the lever L or switches 135 or both are released the corresponding valves automatically return to their midpositions and movement of the arm and jib is stopped.
