Title: Systems for supplying liquid at substantially constant pressure
IPC: E03B5/02
Filed: 1962-10-11
Abstract: 948,597. Control of two A.C. motors. FMC CORPORATION. Oct. 11, 1962 [Oct. 20, 1961], No. 38617/62. Heading H2J. [Also in Division F1] Electric motors 12, 13 each drive a pump, one pump operating continuously and the other pump being brought into operation only when the demand is high. When a switch 32 is in the position shown, the pump driven by motor 13 acts as the main pump, while the pump driven by motor 12 acts as the standby pump, these roles being reversed when the switch is in the other position. Switches 30, 31 for the motors 12, 13 respectively have a left-hand position for manual operation and a right-hand position for automatic operation. With switches 30, 31 in the automatic position, switch 32 in the position shown and main switches 29 closed, motor 13 is started by means of solenoid 36 which closes contacts 46. If the flow demand exceeds the capacity of the pump driven by motor 13, the discharge pressure drops sufficiently to close a pressure-controlled switch 26, thereby energizing a solenoid 41 which in turn closes normally open contacts 39, 40. Contact 40 brings the motor 12 into operation through solenoid 33 which closes contacts 45. Contact 39 maintains the solenoid 41 energized independently of switch 26 and any subsequent opening of the switch 26 due to pressure fluctuation therefore does not stop the motor 12. The motor 12 remains in operation until the flow demand drops to the point at which a switch 28, controlled by the volumetric discharge of the pumps, opens to de-energize the solenoid 41. If the discharge pressure becomes abnormally low, indicating trouble, a pressure-controlled switch 27 opens to stop both motors. Additional pumps, each driven by an electric motor, may be provided, their motors being started and stopped sequentially with the motor 12. If a motor is overloaded, heaters 34 or 37, which are in series with it, open the respective normally-closed contacts 34 or 35 to stop the motor and prevent burnout.

Title: Spillage chute for travelling grate machine
IPC: F27B21/06
Filed: 1966-08-30
Abstract: 1,093,070. Conveyers; shoots. METALLGESELLSCHAFT A. G. Aug. 30, 1966 [Aug. 31, 1965], No. 38727/66. Headings B8A and B8S. At the discharge end of a travelling grate machine, a spillage shoot 20 and idler sprockets 5 are able to move longitudinally of the machine independently of a main frame 2. The arrangement ensures that, despite thermal expansion of a long line of abutting pallets 7, the sprockets 5 will always be in position to properly engage each pallet as it is pushed off the end of a trackway 3. Bearings 9 for the shaft 6 of the sprockets 5 are suspended by hangers 11 from a frame structure 12, the hangers being movable horizontally along rails of the structure 12. The pallets 7 discharge into a structure 8 as they are carried around by the sprockets 5 before engaging lower rails 4. A counterweight 17 operating via sheaves 14, 16, 16a and a cable 15, biases the sprockets towards the left. For receiving spillage, e.g. pellets, as the pallets move into the emptying position, a shoot 20 has runners (21) which rest on rollers (22) carried by the frame of the machine, Figs. 3-5 (not shown). The sprocket shaft (6) passes through the shoot structure with only a working clearance and longitudinal movement of the shaft imparts corresponding movement to the shoot 20 which maintains its position relative to the positions where spillage occurs. The shoot includes plates 26 which deflect the pellets for discharge through side openings (28) on to curved plates (29) and into external shoots (32).

Abstract: 1394349 Moulding hollow articles KRAUSSMAFFEI AG 16 Aug 1973 [26 Aug 1972] 38784/73 Heading B5A Hollow articles such as battery containers 1 are made in a mould comprising a plurality of core parts 4-9 arranged side by side, each core part comprising a core neck 4b-9b and a freely projecting core 4a-9a, the core necks being provided with plane parallel contact surfaces 17 so that they can rest against each other at least in their central region, and a pressing device (e.g. wedge pieces 15, 16) acting on the two outer core necks being provided for pressing the contact surfaces together. As shown in Fig. 1 the core necks are fixed by screws 18 to a mounting plate 10 which is screwed to an intermediate plate 12. The wedge piece 16 is guided in the plate 12 by means of a groove 33 and a pin 34. The intermediate plate 12 is connected to a cover-plate 11 by means of screws 19 which are spaced therefrom by a gap 25. The parts shown in Fig. 1 may be clamped between the mould support plates of an injection moulding machine. After the injection process the cover-plate 11 is lifted, thereby raising the wedge piece 15 and releasing the pressure on the core necks. After moving a short distance (corresponding to gap 25) the plate 12 and a stripping plate 13 are entrained, and the container 1 withdrawn from the lower mould part 3. The stripping plate 13 is now moved downwards to remove the container 1 from the cores 4a-9a. In a modification (Fig. 4, not shown) the core part (31) is suspended on projections (26) instead of being fixed to a plate.

In an advancing mine roof support a pair of hydraulic or non-hydraulic props 1, 2 are connected by horizontal pivots to the ends of a rocker beam 3 centrally pivoted about a vertical axis on a hydraulic shifting cylinder 15 whose piston rod 16 is universally pivoted at 18 to a conveyer, the angular movement of the beam 3 relative to the cylinder 15 being limited by resiliently-mounted stops. During advance the props are released alternately, the beam 3 being swung about the front prop to advance the rear prop each time the conveyer is moved. The rod 16 is normally at right angles to the conveyer. If the advancing movements result in a deviation from this angle, energy is stored in the resilient mounting of the stops, said energy being released at the next advance to restore the right-angles relationship. The props thus automatically follow the movements of the conveyer. The resilient mounting for the stops may be provided by springs, but as shown the stops comprise lugs 37, Fig. 3, engaging apertures in a cage 38 on the beam 3, the lugs being resiliently connected to a tube 28 through a compressed rubber sleeve 35. The tube 28 is pivoted on the cylinder 15 by a transverse pin 27. Compressed rubber sleeves, Figs. 1, 5, 6 (not shown) are also used to form resilient pivotal connections between the end of the beam 3 and the props 1, 2.

Filed: 1966-09-09
Abstract: 1,154,473. Digital transmission systems. GENERAL ELECTRIC CO. 9 Sept.. 1966 [4 Feb., 1966], No. 40472/66. Heading H4P. The invention provides a frequency shift receiver in which is derived in a first embodiment a pulse train of steadily changing pulse width, and in a second embodiment a pulse train having one of two phases. The binary data is derived from the pulse trains. The first embodiment is as shown in Fig. 1, the f.s.k. signal being fed in at 2, and the reference frequency being the centre frequency of the f.s.k. signal. The input to filter 8 during each cycle of the deviation frequency is a pulse train of steadily changing pulse width, The filter provides a sawtooth output which has a slope dependent on the bit sense and which feeds the phase splitter. Bi-stable 13 develops the binary data in polar form. In the second embodiment, Fig. 3, the input at 22 comprises frequency multiplex f.s.k. data. By suitable choice of the reference generator frequency and of the pass-bands of the filters pulses belonging to one channel only, and at the deviation frequency, appear at the waveshaper outputs. The phase shifter gives a shift of about 90 degrees so that the output of shaper 28 leads or lags that of 34, depending on the bit sense. The binary data appears at 23.
