Title: Improvements in and relating to the dressing of bearded needles for knitting machines
IPC: B21G1/12
Filed: 1954-12-20
Abstract: 764,841. Knitting. VERWALTUNGSGES DER WERKZEUGMASCHINENFABRIK OERLIKON. Dec. 20, 1954 [March 30, 1954], No. 36774/54. Class 74 (2). [Also in Group XX] In a machine in which a needle beard can be dressed in two mutually perpendicular planes, an illuminated image of the beard 6a of the needle 6 is superimposed on the enlarged silhouette of the needle, cast on a screen 4 bearing a drawing of a correctly-shaped needle, by episcopic projection, as by mirrors 8 which reflect part of the silhouette-forming beam on to the beard, or by a separate illuminator, the plane containing needle stem and beard being perperpendicular to the screen. A suitably proportioned rectangular colour filter on the condenser lens 2 and a rectangular slit in a diaphragm 7 ensure that the silhouette-forming part of the beam shall be coloured whilst the light falling on the mirrors remains white. The needle is held in a chuck comprising a generally cylindrical body 30 pedally rotatable about its axis through 90 degrees as required through a pulley 37 and cord 38, and a jaw 32 bearing a pivoted clamping piece 33. The jaw 32 is housed in a bifurcation at one end of an axially slidable rod 31, being connected thereto by a lost motion device comprising a pin 44 sliding in an inclined slot 43 in the jaw. As the jaw reaches its forward, clamping position, it abuts against a pin 35 positioned slightly above the centre line, so that it is rocked, and thus the movement of the clamping piece down on to or away from the needle stem is without sliding on it. The dressing device comprises jaws 12, 13, opened and closed by the rotation of segments 16, 17 containing arcuate grooves 19, 30 in which move pins 12b, 13b on the jaws. When segment 16 is turned, it carries segment 17 with it, so that both jaws are moved, but turning of segment 17 moves jaw. 12 only. The segments rotate in a guide piece 15 rotatably mounted in a carriage 14 slidable on two bars 11 parallel to the needle axis and fixed to a vertically slidable plate: the degrees of freedom necessary for the manipulation of the jaws are thus provided.

Title: Diagnostic compositions
IPC: C12Q1/54
Filed: 1960-10-27
Abstract: A diagnostic composition for the detection of glucose comprising glucose oxidase, uroferriporphyrin of formula <FORM:0891275/III/1> and a colour forming substance oxidizable by H2O2 (formed by the oxidation of glucose).  The colour forming substances specified are 2,7-diaminofluorene, O-tolidine and leucoindophenols. Complex-forming compounds containing amine donors groups, e.g. 2-amino benzothiazole nicotinic acid or pyridine, may also be incorporated in the composition.  Additives as protective agents and wetting agents (e.g. Algin) and an inert dye to impart a uniform background colour may also be added, as well as a buffer system to maintain a pH range between 3 and 7 and preferably at 5,4.  The test device may be a tablet or a powder but it is preferred to employ the reagent composition on bibulous carriers such as strips of filter paper.  In Example 1, the impregnating solution is prepared from aqueous algin, citrate buffer, gelatin, a dye, 2:7-diamino fluorene dihydrochloride, glucose oxidase and the uroferriporphyrin.  Half of the filter strip is impregnated with the diagnostic composition, the other half having a water impervious barrier of ethyl cellulose. Examples 2, 3 and 4 differ only in the choice of colour forming substance and/or the addition of 2-aminobenzothiazole. Specifications 575,612, 784,548, 886,778 and U.S.A. Specification 2,848,308 are referred to.

Title: Grab for lifting sacks, bales and like articles
IPC: B66C1/59

Abstract: 870,839. Sack grabs. FOGDEN, T. Jan. 22, 1960 [Nov. 18, 1958], No. 37104/58. Class 78(4). As a sack grab is lowered into engagement with a sack a pad 7 abuts the sack and through a rod 6 lifts a cross-bar 8 out of engagement with plates 5 thus allowing jaws 4 to descend and grip the sack. The grab is attached to a tractor by an arm 15 of a loader, as described in Specification 863,270. As the grab is raised a cam 12 rotated about a pivot 14 by the arm 15 and a member 13 turns the cross-bar 8 in the direction of arrow F against a spring 10 until it drops behind plates 5. When the jaws 4 are relieved of weight, the spring 10 turns the cross-bar 8 which forces apart the plates 5 and opens the jaws 4.

Title: Time fuses

Filed: 1971-08-11
Abstract: 1500687 Electric time fuzes DYNAMIT NOBEL AG 11 Aug 1971 37789/71 Heading F3A A time fuze which is adjustable over a wide time range comprises a component which has an anode and a cathode and in which an electrochemical process takes place when it is in a complete electric circuit loop and eventually the voltage between the anode and the cathode changes radically, a switch operable by the change in voltage, and an igniter operable by the switch. As shown the fuze comprises three circuits: (a) a programming circuit in which an electrochemical cell 11 is connected through resistance R 2  with voltage source U; (b) a timing circuit in which the electrochemical cell is connected through resistance R 1  and electronic or electromagnetic switch Th with the voltage source U; and (c) a firing circuit in which the fuze igniter Z is connected through switch Th with the voltage source. Circuit (a) is first completed to charge the device, conductive material being deposited on the anode of cell 1. By adjustment of switches S 1 , S 2 , circuit (b) is completed and the polarity of cell 1 reversed, so that conductive material is eroded from the anode. When the eroding process ceases, there is a voltage surge which operates the switch Th and fires the igniter Z by means of energy stores in condenser C 1 . The ratio R 1  : R 2  determines the ratio between the delay time and the charging time. To compensate for the effect of temperature variations on the cell 1, resistances R 1  and R 2  may have positive temperature coefficients; alternatively a voltage divider and a resistance having a negative temperature coefficient may be used, Fig. 2 (not shown). An independent voltage source may replace the condenser C 1 , and a rechargeable battery may replace the electrochemical cell 1.

Abstract: 927,495. Radomes. GENERAL ELECTRIC CO. Ltd., and S. CORNBLEET. Oct. 17, 1961 [Nov. 4, 1960], No. 38077/60. Class 40 (7). [Also in Group XXIII] A radome is manufactured by a process which includes a first step of forming in a liquid a suspension of scales of a dielectric material, there being mutual repulsion between the scales so as to maintain neighbouring scales substantially parallel to one another, a second step in which the scales are caused or allowed to congregate one upon the other to form a composite layer, again with adjacent scales parallel, and a third step of drying the layer so formed. The dielectric material is vitreous quartz or more preferably glass composed of silica, boric oxide and alumina. The liquid is water or a dilute solution of acid or alkali. The suspension is placed in a hollow conical mould and the particles aligned under the influence of the inherent electric double layer existing between the flakes and the liquid. The mould is then rapidly rotated to cause a layer of the material to be formed on the outer wall of the mould. The free liquid is drawn off as the deposition of the layer proceeds and is replaced by more of the suspension. When a sufficient layer has been formed it is dried at 80‹ C. for 1 hour or at a higher temperature under pressure. As an alternative to mould rotation, the scales may be allowed to separate under gravity and the radome is then shaped before drying. A laminated radome is disclosed comprising inner and outer layers of aligned glass scales and a centre layer of loosely bound glass scales. The invention is applied to guided missiles.
