Abstract: 1306599 A device for dispensing articles, or substances, for example to a packaging machine BRITISH VISQUEEN Ltd 15 July 1971 [12 Aug 1970] 38868/70 Heading B8C A device for collecting and delivering successive loads of articles, or substances, comprises a pair of vertical coaxial tubular members 1, 2 one mounted partially within the other with means for providing repetitive up-and-down movement of one relative to the other, the outer member 1 having spaced around a perimeter of its inner surface a plurality of flaps 3 which are hinged at 4 to said surface, and which extend through corresponding slots 7 in the inner member 2. The slots engage, with their chamfered, lower edges 9, when the tubular members 1, 2 are respectively at their lowermost and uppermost limits of said relative movement, the free ends of the hanging flaps, and the flaps at a position closer to their hinged ends to hold them at a predetermined angle to the vertical and form a barrier across the interior of the tubular member 2. In the latter position the flaps, preferably horizontal, may be slightly spaced, touch each other, or overlap in which latter case the levels of the lower edges 9 of the slots 7 are staggered. The flaps 3 may be surfaced with rubber or similar material. As shown, the inner tube 2 is reciprocable within the outer, stationary, tube; however, the converse arrangement may be adopted. The drive for the relative movement between the tubes 1, 2 could be pneumatic, hydraulic, electrical, or mechanical, and the components of the device may be made of aluminium, stainless steel or plastics material such as nylon. The upper side of each slot may be covered interiorly by a thin plate to protect the hinges 4 from contact with the commodity handled, the hinges being carried by removable plates. The device may be used in the wellknown form, fill, and seal packaging method for fragile, bruisable &c. articles, the outer stationary tube 2 being used as a former around which the flexible packing material is formed into a tube. The device may also be used as a sack filling head and for delivering articles, or substances, into other kinds of containers. It may also be incorporated into a weighing machine, providing a container for collecting a pre-weighted batch of goods and delivering them, for example, to a packaging container. The device may be used in conveying systems for moving successive loads of articles or substances.

Title: Thermally-responsive electrical switching arrangements
IPC: G01K1/02
Filed: 1970-09-03
Abstract: 1310030 Switching systems for AC loads OTTER CONTROLS Ltd 7 Sept 1971 [3 Sept 1970] 42243/70 Heading H2H A thermally responsive switching arrangement comprises an electronic switch 1 for switching the current through a load 2 and a triggering circuit for the switch, the triggering circuit including a variable inductance with which is associated a thermo-mechanical transducer for varying the inductance in dependence on the temperature so that-the triggering of the switch depends on the value of the variable inductance. The electronic switch is preferably a triac but an S.C.R., a thyratron or a power transistor may be used and the thermomechanical transducer may be a bimetal strip, a Bourdon tube or a pneumatic phial which varies the inductance, for example by varying the relative positions of a coil and a core or by varying the relative positions of portions of a core. In the embodiment shown in Fig. 2, a capacitor 8 and a resistor 9 have a small time constant compared with the duration of a half cycle of the A.C. supply and when the capacitor voltage exceeds the breakdown voltage of a silicon bidirectional switch 7, the capacitor discharges through the primary of a transformer 3 to supply a trigger pulse to switch on the triac provided the temperature is such that the thermo-mechanical transducer has set the mutual inductance of the transformer at a value which enables sufficient gate current to pass to the triac. Thus the temperature determines whether the triac is switched on or off in each half cycle of the supply. In the embodiment shown in Fig. 4, a diac 11 supplies a number of pulses to the transformer 3 during each half cycle of the supply. These pulses are superimposed on a ramp voltage generated by a capacitor 12 and switch on the triac at an instant in each half cycle which depends on the temperature, since the variation of the mutual inductance of the transformer with temperature causes a variation of the amplitude of the pulses. Thus in this embodiment the power supplied to the load, which may be a fan or a heater, is varied in dependence on the temperature. The ramp voltage may be made temperature dependent by using a thermistor for the resistor 13. The switching of the triac may be arranged to take place at the zero cross overs of the A.C. supply.

Filed: 1969-02-27
Abstract: 1314672 Tractor power lift mechanism NATIONAL RESEARCH DEVELOPMENT CORP 26 May 1970 [27 Feb 1969] 10474/69 Heading A1P A three point lift mechanism is arranged so that both upper and lower links AB and CD respectively respond only to that component of force acting on the implement which is parallel to the tractor wheelbase. Rods 3, 5 set in springs 2, 6 respectively respond to tension or compression in the above mentioned links. Spring loaded lever 4 receives movement from rods 3 and 5 (from the latter via a Bowden Cable) and acts on control rod 8, the ratio a/b being the ratio of the ratio of springs 2 and 6 respectively. Control rod 8 acts on balance lever 9 which actuates the power lift cranks 23 via tie rod 11 and hydraulic valve 12. Variation of draft force causes the lift linkage to be raised or lowered so the working depth of the implement will be altered to keep the draft force substantially constant. In further embodiments both upper and lower links may be connected to their respective rods via vertical levers, or vertical flexible cantilever plates or electrical pressure transducers can be used as the draft force sensing means. The power lift may also be raised or lowered by means of an electric motor controlled by a switch replacing control valve 12. Upper link AB may be so arranged that the forward extension of its axis intersects that of the lower link CD at a point in front of the tractor rear axle to improve draft control on pitching.

Abstract: 1338611 Photo-electric fault detection BRITISH AIRCRAFT CORP Ltd 19 April 1971 [16 Feb 19701 7315/70 Heading G1A. [Also in Division G2] Faults in a moving sheet of glass 11 are detected by scanning a focused laser beam 14 back and forth across the sheet and detecting light scattered from the faults either visually or photoelectrically. In the photo-electric embodiment, the laser 13, focusing lens 15 and two photo-cell pairs 21/22 and 23/24 are scanned together. Detectors 22 and 24 are provided with lenses and hence pick up light scattered from smaller defects, whereas detectors 21 and 23, which may be photomultipliers, respond to scattered light and interference fringes resulting from larger defects. Two arrays 19, 20 of stationary photo-cells define between them a passage for unscattered light, and hence also respond to any scattered light. For visual observation, Fig. 1, (not shown), the sheet of glass is passed between a pair of screens (2, 3) each having a slit (4, 5) through which the scanning beam passes. Light scattered from defects produces patterns on these screens, different types of defect producing different types of pattern.

Abstract: 1353674 Spot-type disc brakes; fluid or spring actuation; fluid release KELSEY-HAYES CO 14 July 1971 [21 July 1970] 42908/73 Divided out of 1353673 Heading F2E A spot-type disc brake assembly comprises a housing 19 having a bore 22 accommodating a fluid-operated piston 18 which applies a pad 15 to a rotor 12, biasing means (as shown, Belleville springs 46) connected with the piston so as to exert an actuating force on it when required, and release means such as an auxiliary piston 51 for relieving the piston 18 of the force exerted by the biasing means. Preferably, automatic adjustment means is incorporated as described below. As shown, the housing 19 is a sliding caliper, and a second main piston 17, Fig. 1, with the associated apparatus, is provided. The Belleville springs 46 act between a washer 37, Fig. 2, non-rotatably mounted at the inner end of bore 22, and a sleeve 24 having a screw-thread connection with an adjusting member 29, having a head 31 adjacent the piston head; a torsional spring 36 encircles the head 31 and is fixed at one end to piston 18 to act as a one-way clutch. Sleeve 24 is prevented from rotating by the washer 37 (see Fig. 2). A clearance is provided between head 31 and piston 18 to permit normal actuation and release of the piston. During normal running, an engine-driven pump 58 delivers fluid to the left of auxiliary piston 51 which through screw connection 52, 53, draws sleeve 24 and hence member 29 to the right, compressing springs 46. Brake pads 15, 16, now have light rubbing contact with disc 12. For fluid-pressure brake application, chamber 23 is pressurized, whereby piston 18 applies pad 15 and pad 16 is applied by reaction; on pressure release, the brake is released by recovery of a seal 66 surrounding piston 18. After excessive pad wear, fluid-pressure operation of the brake causes such movement of piston 18 leftwards that collar 33 (located across piston 18) tends to pull adjusting member 29 to the left through the agency of a thrust bearing 35 and the head 31. In consequence, member 29 is partly unscrewed from sleeve 24, such rotation being permitted by the one-way spring clutch 36. For parking brake actuation it is sufficient to switch off the vehicle engine, whereupon pressure is lost at 58, 57 and space 56, permitting springs 46 to move sleeve 24, member 29, piston 18 and hence pad 15, to the left and, by reaction, pad 16 to the right.

Title: Enzymatic conversion of proteins using immobilized dictyostelium dipeptidylaminopeptidase
IPC: C12N9/50
Filed: 1994-12-15
Abstract: The present invention concerns a novel process for using a recently discovered dipeptidylaminopeptidase isolated from the cellular slime mold, Dictyostelium discoideum (dDAP). The claimed process involves immobilizing dDAP onto a support surface so that even numbered, N-terminal dipeptides can be efficiently removed from precursor proteins or polypeptides to yield desired processed proteins or polypeptides. The invention provides a means for reusing dDAP in multiple conversion reaction runs, as the enzyme does not become a part of the substrate/product solution. The claimed process is particularly useful for converting a precursor human proinsulin analog (Met-Arg-Human Proinsulin having Lys at position 28 and Pro at position 29 of the corresponding insulin B-chain; MR-KPB-hPI) to a processed insulin analog (Human Proinsulin having Lys at position 28 and Pro at position 29 of the corresponding insulin B-chain, KPB-hPI).
