Title: Meat pre-tenderisation
Inventor: WARREN SIMON JAMES
IPC: A23L13/70
Filed: 1990-07-30
Abstract: A method of pre-tenderising meat comprises introducing a proteolytic enzyme into the vascular system of a substantially brain-dead animal whilst the animal's heart is still beating. The method may comprise stunning the animal (1) with a mechanical stunning pistol (6) to cause brain death, infusing a proteolytic enzyme such as papain bromelain or ficin into the animal using a burette (7) whilst the animal's heart is still beating and then bleeding the animal in order to stop the heart beating after a suitable time has elapsed for the enzyme to be distributed within the vascular system of the animal. The enzyme can be infused more easily when the animal is in a prone position, and the process is faster and more humane than prior art processes in which the enzyme was injected into the conscious animal.   <IMAGE>

Title: Cutting machines
Inventor: MCDONALD IAN WILLIAM
IPC: B26D1/553
Filed: 1990-08-13
Abstract: A machine for cutting soft or semi-soft materials, for example cheese, comprises a plurality of cutter wires, the distance between adjacent cutter wires being adjustable. The wires are preferably arranged on a frame which is of variable geometry so that on changing the shape of the frame, the distance between adjacent cutter wires is changed. Particularly preferred is the use of two overlapping sets of parallel wires 9, 22 past which a block 1 of cheese is pushed to form trapezoidally sectioned pieces. Raising or lowering of the common side member 6 of the two frames 5, 6 carrying the wires 9, 22 causes the distance between adjacent wires in the two sets to increase or decrease. To facilitate packaging of the resulting cut pieces, it is preferred to effect rotation of either or both of the pieces until their respective orientations are substantially identical, for example by rotating the pieces in opposite senses through angles of approximately 90 DEG . <IMAGE>

Title: Cutter bit assemblies
Inventor: STEINKUHL BERND
IPC: E21C27/44
Filed: 1990-10-24
Abstract: A cutter bit assembly for a mining or tunnelling machine has a shank (6) of the cutter (4) detachably fitted into a socket (3) of a holder (2). To secure the shank in position a piston (24) is displaced to cause pressure fluid to flow into a working chamber (20) and act on a piston (19) at one end of a rod-like securing element (17). The element (17) is forced against a surface (16) of the shank to urge the shank about a pivot (11, 12) and this in turn thrusts rear support surfaces (14, 15) of the cutter and the holder together. To release the cutter the pressure fluid is relieved and spring (22) displaces the securing element away from the shank. In this released condition, the cutter can be swivelled about the pivot (11, 12) and withdrawn from the socket. <IMAGE>

Title: Ultrasonic cleaning
Inventor: LITTLEFORD GORDON EDWIN
IPC: B08B3/12
Filed: 1990-10-29
Abstract: Hydrocarbon solvent materials having a relatively high flash point and susceptible to mist formation and regarded as poor for cavitation can be used for ultrasonic cleaning by immersing an object in the solvent 11 in a first tank 10, providing a volume of water 12 in intimate contact with a wall 14 of the first tank 10, and generating ultrasonic acoustic energy within or transmitted to said volume of water to create acoustic coupling at the liquid/solid interface. Preferably, a heat pump (24) is used to heat the solvent (11) and maintain it at a safe temperature, below the flash point. As shown, a transducer 20 transmits ultrasonic acoustic energy to the flow of water maintained by a weir 22 in good acoustic coupling at the wall interface 14 which has a 40 slope to shift air bubbles. A four-stage cleaning system could have a cleaning stage followed by two rinsing and a drying stage. <IMAGE>

Title: Circuit means for rotational angle setting determination
Inventor: ZIMMERMANN WERNER
IPC: H03M1/30
Filed: 1991-02-01
Abstract: Circuit means for determining the rotational angle setting of a rotating element, such as a shaft in an internal combustion engine, comprises a counter (26), and sensing means (not shown) which detects the rotational angle setting of the element and the output signals (x, y) of which are fed to an evaluating circuit (14), wherein the rotational angle setting resolution of the evaluating circuit is greater than that of the sensing means. A synchronising circuit (15) produces a synchronism between the output signals of the sensing means and the associated highly resolved rotational angle originating from the evaluating circuit. In order to make the highly resolved measurement value available in simple manner, it is proposed that setting of the counting speed of the counter (26) is effected through a comparator (24) co-operating with the output signal of the sensing means in such a manner that the counter counting state (i) changes at a first frequency (f1) when the comparator (24) is in one state and that a change is undertaken at a second frequency (f2) when the comparator assumes its other state. <IMAGE>

Filed: 1991-06-12
Abstract: The invention relates to a process for obtaining a gaseous nitrogen/hydrogen mixture for the synthesis of ammonia. According to the invention, there is carried out a catalytic conversion, in two phases (stages), of hydrocarbons in the presence of steam and an excess of compressed air, which provides a nitrogen/hydrogen mixture containing carbon monoxide, and a subsequent conversion, by steam, of carbon monoxide to carbon dioxide and hydrogen; the process comprises, successively, the separation of carbon dioxide, methanisation of carbon monoxide residues, separation of excess nitrogen from the nitrogen/hydrogen mixture at a pressure in the region of that of the starting mixture and, simultaneously, separation of hydrogen at a pressure whose value lies in the range between the pressure which is substantially equal to that of the starting nitrogen/hydrogen mixture and the pressure at which synthesis of ammonia, the final product, is carried out. The invention will find applications in the chemical and petrochemical industries.
Patent GB-913885-A (GB)
IPC: F21V19/02
Abstract: 913,885. Flash-light units. HEHL, A., HEHL, K., and HEHL, E., [trading as ARBURG FEINGERAETEFABRIK OHG. HEHL & SOHNE]. Nov. 9, 1960 [Aug. 23, 1960], No. 38478/60. Class 9 (2). A flash-light unit has a magazine 12, preferably injection moulded from a transparent thermoplastic material, which is attached to a easing 7 by the passage of rim 17<SP>1</SP> within a groove 18a and lugs 15, 15<SP>1</SP> in channels 18. When the magazine 12 is separate from the casing 7, flash-lamp bulbs 5 are held within the former by the resiliency of the material at the lower end of the magazine, the opening being preformed to a size such as to prevent free passage of the flash-lamps. On attaching the magazine to the casing, the lugs 15, 15<SP>1</SP> are forced apart by the channels 18 which diverge and groove- 14 assumes a rectangular shape rather than the tapered shape as shown at Fig. 5. The arrangement is such that when the magazine is pushed fully into position the flashlamps are free to fall under gravity, the lowest descending into an opening in rim 8a of a rotatable disc 8 housed within the casing 7 (see Fig. 9). On rotating the disc by means of handles 81, 8<SP>11</SP> which project through the rear wall of the casing the lamp is pushed vertically downwards by a feed channel 8<SP>111</SP> into socket 9, and a lamp already present is forced out of the socket 9 into a discharge opening 6 (not shown). Only one lamp at a time is fed to the socket since each lamp is initially held by abutment 8<SP>iv</SP> and on rotation of the disc 8, rim 8a prevents the movement of an adjacent lamp. The sockets of the lamps are of reduced cross-sectional area and are guided by a vertical groove 13 in the magazine 12 and a continuation groove 4 (not shown) in the casing.

Title: MRI method with increased z-axis slice resolution
Inventor: HENNIG JUERGEN
IPC: G01R33/54
Filed: 1992-11-11
Abstract: The excitation frequency in a slice-selective MRI scheme is incremented by a fraction (1/m) of the normal inter-slice frequency step  DELTA f between successive phase-encoding and signal-recovery sequences. It is thus possible to construct a slice image with its centre at m different points between conventional slice planes, by using a whole set of phase-encoded data derived from contiguous sub-slices displaced in varying degrees from the desired plane. Treatment of artefacts due to this displacement are discussed. <IMAGE>
