Filed: 1924-07-28
Abstract: 235,034. Woosnam, A., (Barry-Wehmiller Machinery Co.). July 28, 1924. Bottles, washing.-In a bottle-washing plant comprising a continuously-driven soaking machine and an intermittently-driven washing machine arranged in series, lever mechanism actuated by the driving shaft of the washing machine is provided; for opening the bottle holders of the soaking machine as they pass the intake shoot of the washing machine. The bottoms of the bottle cages 2 on the soaking chains 1 consist of sliding racks 4 movable in guides 2<a>, cross-rods 4<a> supporting the bottles when the racks are in the lefthand position, Fig. 2. As the holders pass the intake shoot 3 of the washing machine, a striker arm 13 which has been retracted into the position shown dotted, Fig. 2, against the action of a counterweight 11<d> by a cam 9 on the driving shaft 8 of the washing machine acting through levers 10, 12 and 11 is suddenly released to strike the head 4b of the rack 4 thus sharply moving it to the right-hand position and releasing the bottles, which slide down the shoot 3 into the carrier 6<a> of the washing machine. Geneva stop mechanism 8<a>, 8b, 5a actuates the washing machine intermittently and this driving mechanism is co-ordinated with the drive of the soaking chains so that a row of carriers 6a is in position to receive each row of bottles as they are released. The washing machine may be of the kind shown in Specification 102,866 in which the bottles are subjected to sprays 14, and may deliver the bottles by a shoot 7 to swilling and uprighting machines.

Title: Radar fire control system
Inventor: SHANK ROBERT J
IPC: F41G9/00
Filed: 1956-06-12
Abstract: 843,770. Thermionic distributers. HUGHES AIRCRAFT CO. June 12, 1956, No. 18193/56. Class 40(3). [Also in Groups XXI, XXXIII and XL(c)] In a radar system (see Group XL(c)) a plurality of different signals are applied sequentially to a C.R.T. display through respective cathodefollower gates 129, 131 ; 132, 133 ; 134, 135, Fig. 4a, controlled. by timedisplaced recurrent gate pulses 1, 2, 3, 4, Fig. 7. Each signal comprises an A.C. voltage applied in push-pull to the grids of a cathode-follower pair, the appropriate gating pulse being applied in parallel to the grids via a centre tap on a signal coupling coil, e.g. 159 or 162, or via the junction of two resistors 163, 164 connected between the grids. The circuit Fig. 3 producing the gate pulses comprises a ring circuit of four free-running multivibrators 43-46, Fig. 3. Operation of the circuit is initiated by energizing a relay 93 to close contacts 111, 112 and 94, 92 and in this condition the anode of the A section of each multivibrator is coupled (1) to the grid circuit of the A section of the succeeding multivibrator, (2) through a load resistance 76 to a positive voltage supply +B and (3) to a respective gate output terminal 117, 118, 119, and 114 which are also connected through diode clamps 96, 107, 108, 109 to a voltage stabilizer 99. The cathodes of the multivibrators are directly connected to a negative 250v. supply, the anodes of the B sections are connected to earth, and sync pulses 706, Fig. 7, produced by differentiating a 133<SP>1</SP>/ 3  c/s square wave 703 from a control multivibrator 42 are applied to the grids of the B sections of multivibrators 43-46 such that each gate pulse is initiated and terminated respectively by successive negative pulses of the sync waveform 706. In order to prevent operation of the ring counter in the wrong direction, a feedback loop is provided between the anode of the B section of multivibrator 44 and the grid of the B section of multivibrator 46 through a capacitor 115 and in order to prevent false triggering of the counter by signals in other channels of the system, a resistor 116 is coupled between anode 75 and gate 1 terminal 117. When the control relay coil 95 is de-energized the anodes of the B sections of multivibrators 43-45 are disconnected from earth and the corresponding A sections are continuously conductive thereby producing negative D.C. voltages at the gate terminals 117, 118, 119; the anode of the A section of multivibrator 46 is disconnected from its output terminal 114 so that a positive D.C. voltage appears thereat and the B section is continuously conductive. Each signal controlled by a gate pulse comprises an A.C. voltage applied in push-pull to the grids of a pair of cathodefollowers, e.g. 129, 131; 132, 133; 134, 135, Fig. 4a, the appropriate gating pulse being applied in parallel to the grids via a centre tap on a signal coupling coil, e.g. 159 or 162, or via the junction of two resistors 163, 164 connected between the grids.
