Title: Improvements in or relating to a method of and apparatus for facilitating slaughter and for bleeding slaughter animals
Inventor: MURPHY LAURENCE WEBSTER
IPC: A22B5/04
Filed: 1956-08-02
Abstract: 809,342. Slaughtering animals. HORMEL & CO., G. A. Aug. 2, 1956, No. 23933/56. Class 5(1). [Also in Group XXX] Apparatus for use in the slaughtering of pigs and other slaughter animals comprises a horizontal endless slat conveyer (see Group XXX) which receives the animals from a conveyer X issuing from a chamber in which the animals have been immobilised by anaesthetic, the slats 13 being provided with a depressed grid portion composed of rods 24a welded to the slats at one side of the conveyer to receive the head and forelegs of the animals so that the animals may be slaughtered by sticking them at C to sever the carotid artery and jugular vein, the blood passing through the depressed grid portions into a receiving trough T during travel of the conveyer. The conveyer is of a length such that drainage of blood is complete before reaching the delivery end of the slat conveyer, where the animals are delivered to a soaking and scalding tub Y. A shoot S disposed between the conveyer X and the slat conveyer provides a slide surface enabling each animal to be turned manually into correct position for sticking as it is transferred to the slat conveyer. Immediately after sticking, the animals come into contact with a hold-down conveyer belt 14 supported on end pulleys 15, 16 carried by an overhead frame, one of the pulleys being driven so that the belt moves in synchronism with the slat conveyer. Roller assemblies 17 are mounted on the overhead frame each comprising a roller 1 7b carried between the ends of a pair of pivoted links 17a which are spring-urged to press the roller downwardly against the lower run of the belt 14 so that the belt is pressed against the animals to prevent their moving about on the slat conveyer as a result of reflex actions occurring following sticking. It is said that as a result of the lower position of the head in relation to the body of each animal, all the blood is drained through the cut C before the animals reach the end of the slat conveyer. Blood is pumped away from the trough T through a hose 32. A splash plate 33 is positioned in front of the trough.

Title: Improvements relating to internal combustion engine fuel pumps
IPC: F02M37/04
Filed: 1959-07-13
Abstract: 867,801. Reciprocating pumps. DAIMLERBENZ A.G. July 13, 1959 [July 15, 1958], No. 23983/59. Class 102(1). A fuel pump comprises an annular piston 7, which also acts as an accumulator piston, loaded by a spring 11. A push-rod 8 extends through the piston and carries an abutment 9, the rod being actuated externally in one direction by suitable means such as a cam or lever and loaded by a spring 10 to urge the abutment 9 towards the piston 7. Under normal conditions liquid is delivered by the upward movement of the push rod 8 which allows the spring 11 to actuate the piston 7 and the return stroke is produced by the spring 10 through the abutment 9. When the delivery pressure increases above a predetermined value the pressure in the pumping chamber prevents the piston 7 performing a complete stroke and this piston then acts as an accumulator piston. When the pressure of liquid forces the piston 7 downward until the spring 11 is fully compressed the piston opens on relief port 14.

Title: Improvements in and relating to Variable Capacity Rotary Positive-Displacement Hydraulic Pumps
Inventor: VANDERSTEGEN-DRAKE STAMFORD RO
IPC: F04C14/22
Filed: 1966-05-27
Abstract: 1,188,526. Rotary positive-displacement pumps. PLENTY & SON Ltd. May 17, 1967 [May 27, 1966], No.23983/66. Heading F1F, A variable-capacity positive displacement pump has a hollow block 30 carrying a tubular rotor 28 with flat surfaces 26 engaged by vanes 24 that are slidable transversely in a portion 22 of a driving shaft 8, the eccentricity of the rotor relative to the shaft being adjustable to alter the capacity by horizontal displacement of the block 30, which is supported by a cylindrical projection 32 and either a piston 34 or a piston 59. The position of the block is regulated either by a hand-wheel 56 coupled to the piston 34 through a rod 54 and an external actuator (not shown) or by a screw 74 and block 70 abutting a compression spring 68, which engages with the piston 59. The piston 34 has a groove (52, Fig. 3, not shown), therein and a cavity 50 associated therewith is connected to an outlet port 6 by way of passages 48 so that said piston damps movements of the block 30 due to transient forces acting thereon. Cavities 58, 62 associated with the piston 59 are connected to the port 6 and an inlet port 4, respectively, so that for my particular setting of the screw 74 the output pressure of the pump is automatically kept substantially constant. Excessive pressure at the port 6 is prevented by a spring-loaded by-pass valve 78. The shaft 8 is driven by a motor 20.

Patent GB-503223-A (GB)
Title: Improvements in and relating to the control of feed water supply to steam generators and boilers
IPC: F22D5/18
Filed: 1937-09-03
Abstract: 503,223. Boiler feed-water regulating devices. ARMSTRONG, C. H., BROWN, N. H., and COPES REGULATORS, Ltd. Sept. 3, 1937, No. 24135. [Class 135] The feed-water supply to a boiler is controlled by a valve capable of a dual regulating movement to vary the area of the flow opening in transverse directions, one of these movements being effected in accordance with the load on the boiler, either automatically or manually in conjunction with a load indicator, whilst the other is effected by another variable operating condition such as the water level. As shown the valve comprises a tubular ported member 4 of the type described in Specification 303,238, [Class 135], which may be both rotated and displaced axially to control port openings 8 in a fixed sleeve 7. The rotary movement of the valve is effected through an arm 28 secured to the spindle 10 and carrying a counterweight 29 which is connected by means of a suitable linkage to a device responsive to the water level in the boiler, for example, an expansion tube thermostat of the kind described in Specification 297,306, [Class 123 (ii)]. The axial movement of the valve member is effected by rotation of a screwed bush 14 which acts on the spindle 10 through thrust bearings 18, 22 and which is rotated by an electric motor 24 through gearing 25, 15. The motor 24 is controlled by a load responsive device such as a flow meter or a U-tube arranged in the steam line. Alternatively the motor 24 may be omitted and the gearwheel 15 replaced by a hand wheel for manual operation in conjunction with a load indicator. A spring connection 21 is arranged between the thrust bearing 22 and the spindle, and the pressure of the feed-water supply in the inlet 2 is allowed to act upon the top of the valve 4 through grooves 9 in the top of the sleeve 7, so that increases of the supply pressure tend to compress the spring 21 and so provide an additional adjustment of the valve 4 according to this pressure. An indicating device is carried by a collar 16 on the spindle 10 which is preferably in the form of a replica of the actual valve opening. In a modified arrangement the axial movement of the valve is effected directly by a fluid-pressure servomotor under the control of a pilot valve which is acted upon by a diaphragm subjected to a steam-flow differential pressure.

Abstract: 207,873. Chamberlain & Hookham, Ltd., and James, S. Sept. 6, 1922. Counters affording several rates of actuation.- Relates to maximum-demand electricity meters registering over determined intervals excess quantities above an agreed demand or below a specified power-factor, and in which are used a pair of principal elements, for example, a clock and a meter, and a mechanism controlled by both elements, one element moving the mechanism in one direction and the other resetting it at the end of an interval. Pinions a, b are driven by an ordinary meter normally registering on the counter g, the pinion b engaging or disengaging with a rack c at predetermined intervals when the clock or motor i energizes the electromagnet j. The rack carries a contact d which when the agreed demand is reached engages a readily adjustable contact m positioned by a slider n moving over a scale o. The electromagnet e is then energized and the meter registers on the excess counter h. In practice rotary elements are employed for the rack and readily adjustable elements m, n. Mechanical means may a.lternatively be providecl for changing over from the ordinary to the excess counters. On a powerfactor basis one of the principal elements may be an energy meter and the other a wattless-component or ampere-hour meter, each with its own counter, the same intermediate mechanism being utilized to switch in the wattless-component counter when the power-factor has been lowered sufficiently. The energy meter may alternatively be provided with two counters, or with a single counter registering complex units the wattlesscomponent meter then being connected through differential mechanism when the electromagnet e is energized.
