Abstract: 913,665. Extracting bread &c. from tins. CHARLESFORD ENGINEERING CO. Ltd. Jan. 23, 1961 [Oct. 22, 1959], No. 35865/59. Class 28 (1). Tines 40, Fig. 3, on an oscillatory shaft 38 pick up filled bread, pie or tart baking tins A which have slidden to stop ends 25 of rods 24, and invert them to discharge their contents, e.g. pies B, Fig. 4, into wire baskets 54 on an oscillatory shaft 51 which discharges them to a conveyer 59. The conveyer 59 may deliver the pies B to arms 83, Fig. 9, of a stacker automatically pivoted apart by hydraulic mechanism 89 to drop the stacked pies on a tray 80 when the stacker is full. The machine shown in Fig. 2 (plan view) passes three filled pie tins abreast from an oven discharge conveyer (not shown), via a shaker conveyer 12 with side guides 17, to rods 24 partitioned by members 23, each batch of three tins being successively delivered to the stop ends 25 by rocking detents 28 on a sleeve 31, Fig. 3, actuated by a sleeve 32 through a spring 36 strong enough to yield and allow unrestricted tin feed only on overload. The shaft 38 carries guides 41 which receive the tin side flanges and retain the empty tins on the tines 40 during their return movement to a downwardly directed position where the tins are discharged by gravity aided by the thrust of arms 49 pivoted about a shaft 45 on. coaction with fixed stops 50 of cam slots 47 on arm extension 46.

Title: Telecommunication receivers
IPC: H03H2/00

Abstract: 943,423. Electric signal amplification systems. SOC. ANON. DE TELECOMMUNICATIONS. Oct. 19, 1960 [March 2, 1960], No. 35874/60. Heading H4R. In an amplifying arrangement requiring the amplifier to be matched to the signal source, the source and a matching resistance are connected to a first network, and the output terminal is taken from a second network, the two networks being interconnected by a plurality of amplifiers in such a manner, that signals from the source are present at the output terminal, but noise from the matching resistance is not. The general case is discussed mathematically. In one particular embodiment, Fig. 3, the first network 14 comprises quarterwave line 16 connected between the source 10 and the matching resistance R 2 , the ends of the line being connected by further quarter-wave lines 17, 18 to the amplifiers 3 1 , 3 2 , whose outputs are connected to input terminals of the network 15 which in this case comprises a further quarterwave line 23, the output signal being taken from terminals 12. It is seen that signals from the source 10 arriving at terminals 12 via the two amplifiers reinforce, whereas noise coming from the resistance R 2  via the two amplifiers cancels out at terminals 12. The impedance is made small at the upper ends of lines 17 and 18, so that at their lower ends they present substantially infinite impedance, and so do not upset the matching of the source 10 to the resistance R 2 . Transformers 20, 20<SP>1</SP> however cause the line to present a high impedance to the input circuits of the amplifiers which themselves have low impedance. This mismatch helps to reduce noise. In a second embodiment, Fig. 5, the source 27 of resistance R 0  is connected to the centre point of a half-wave line 28, 28<SP>1</SP> to the ends of which are connected two resistances 26 for matching purposes (these are shown as containing noise sources B 1 ). Amplifiers 3 1 , 3 2 , 3 3  having gain G, 2G, G respectively connect the tappings of the delay line 28, 28<SP>1</SP> to opposite ends of a quarter-wave line 29 as shown. It is proved mathematically that the current in load 30 consists wholly of signal with no noise from the resistors 26, 26<SP>1</SP> whilst the current in load 30<SP>1</SP> consists solely of noise with no signal.

The damper 13 has an electromagnetic servovalve 14 in a by-pass circuit. The signal from the displacement transducer 15 is fed to a function generator circuit 17 which provides an output signal corresponding to the desired value of the body acceleration for the given displacement. This output signal-and the signal from the acceleration transducer 16, e.g. an accelerometer, are compared in a circuit 18, and the resulting error signal together with the displacement transducer signal are supplied to a logic circuit 19 which controls the valve 14. The variable damping controls the vertical acceleration to cause the error signal from the circuit 18 to be minimized. The displacement and acceleration signals from all four dampers of the vehicle may be compared and the damping effects varied so as to control pitch and roll as well as vertical acceleration.

Abstract: 1,109,482. Hydrostatic transmission control. DOWTY HYDRAULIC UNITS Ltd. 9 Sept., 1965 [11 Sept., 1964], No. 37291/64. Heading F2D. A control system for a motor vehicle transmission wherein a variable speed engine 1 drives a variable ratio hydrostatic transmission 3, 6 comprises a single manual control 13 which normally controls both the engine speed and transmission ratio and pressure actuated means 38 . . . 42 which overrides the manual control to effect a change in the transmission ratio when the pressure liquid therein exceeds a predetermined pressure. As shown a variable displacement pump 3 is in closed circuit with a fixed displacement motor 6. A pump displacement control 33 is biased towards a zero displacement position by a spring 19 acting through a plunger 22 and levers 26, 32. A forward-reverse selector lever 28 loads a spring 31 which acts through levers 26, 32 to increase pump displacement in the forward or reverse direction when the bias of the spring 19 is removed. Initial depression of the pedal 13 increases engine speed without moving the pump displacement control 33 until the lost motion of a connection 16 is taken up. Thereafter further depression of the pedal 13 increases engine speed and acts through a bell-crank 17 to relieve the pressure of the spring 19 from the plunger 22 whereupon the spring 31 increases pump displacement and moves the plunger 22 left to follow the movement of the end 18 of the bell-crank 17. Excessive pressure in the high pressure line 4 or 5 acts through a line 30 to move right a plunger 42 which acts through the plunger 22 and levers 26, 32 to reduce pump displacement. In Fig. 2 (not shown) the plunger 42 acts through a lever 43 on the plunger 22. The pump may have a fixed displacement and the motor a variable displacement the control element of which is acted on by the control system. In this arrangement a by-pass valve is provided between the lines 4, 5 which valve is opened when the pedal 13 moves to the engine idle position. Both the pump and motor may have variable displacements. A single lever may replace the lever 28 and pedal 13.
