Title: Improvements in and relating to hydraulic control valves
Filed: 1956-03-08
Abstract: 813,698. Fluid-pressure servomotor control systems. LEAR, Inc. March 8, 1956 [March 9, 1955], No. 7258/56. Class 135. The aluminium or magnesium casing 66<SP>1</SP> houses a pilot valve 10<SP>1</SP>, a relay valve 30<SP>1</SP> and a conically ended shaft 61<SP>1</SP> which is resiliently mounted in substantially frictionless bearings and together with the casing end cap 166 is provided with " O " rings to prevent leakage; the shaft 61<SP>1</SP> has arms 14<SP>1</SP>, 172, which are attached to the valve 10<SP>1</SP> and a rod 174 coupled to a mechanical or electrical force input source, such as a torque motor. One end of a flat coil spring 46<SP>1</SP>, which is connected to the arm 141 and disposed perpendicularly to the axis of the relay valve 30<SP>1</SP>, is attached to the latter by a rod 44<SP>1</SP>. Counter-clockwise movement imparted to the shaft 61<SP>1</SP> by the rod 174 causes leftward travel of the valve 10<SP>1</SP> and opens a port 100 to enable pressure fluid from an inlet 116 to traverse a duct 102 and act upon the outer end of relay valve land 38<SP>1</SP> and since the pressure fluid also acts upon the outer end of relay valve land 34<SP>1</SP>, which is half the area of land 38<SP>1</SP>, the valve 30<SP>1</SP> also moves to the left, which movement continues until the pilot valve returns to its initial position. Pressure fluid is directed from between relay valve lands 36<SP>1</SP>, 38<SP>1</SP> to a port 54<SP>1</SP> connected to one side of a mechanical member 56<SP>1</SP> whilst the other side thereof is connected via a port 52<SP>1</SP> and the space between relay valve lands 34<SP>1</SP>, 36<SP>1</SP> to an exhaust port 122 so that member 56<SP>1</SP> accelerates up to a constant speed corresponding to the degree of opening of ports 104, 106. Concomitantly the inner end of spring 46<SP>1</SP> is also moved leftwardly to exert a clockwise torque on the shaft 61<SP>1</SP> and when the moments on the latter are balanced, the pilot valve 10<SP>1</SP>, arms 14<SP>1</SP>, 172 and rod 174 are returned to their initial positions wherein the pilot valve enables a pressure of one half of the supply pressure to be exerted on the outer end of land 38<SP>1</SP>, which pressure produces a force balanced by that on the outer end of land 34<SP>1</SP>, and the relay valve is held stationary. A succeeding counter-clockwise force applied to shaft 61<SP>1</SP> will cause a repetition of the above operation and the relay valve will be moved further to the left. Clockwise rotation of the shaft 61<SP>1</SP> will result in member 56<SP>1</SP> decelerating to a constant speed dependent upon the degree of opening of ports 104, 106 until the relay valve has moved far enough to reverse the supply and pressure connections to the member 56<SP>1</SP>. The coil spring may be replaced by a torsion bar and the relay valve may have a differential area at both ends.

Title: Improvements in crimping tools
IPC: H01R43/042
Filed: 1954-03-12
Abstract: 750,047. Crimping tools. AIRCRAFTMARINE PRODUCTS, Inc. March 12, 1954 [March 13, 1953], No. 7275/54. Class 61 A crimping tool, for pressure forming an electrical connector about a conductor by closing a pair of die surfaces towards one another with the connector therebetween, is provided with a device which is resiliently urged in a direction from one die surface to the other and which, by cooperating with locating means, such as a depression, in the connector serves to position the connector during the crimping operation. In the construction shown, a slide 24 with die surfaces 26, 28 is mounted in a C-shaped head 22 and moves towards or away from fixed dies 30, 32, upon the manipulation of handles 34, 36. A series of holes 46a, 46b. 46c and a pin 44 permit the adjustment of die 26 with respect to the slide. Upon the head 22 are mounted a sliding bracket 48 and a pivoting bracket 58 provided respectively with means for locating the electrical oonnectors 62, 82 shown in Figs. 8 and 9. To crimp the connector 82 the bracket 48 is first moved upwardly against the action of a spring protected by a cover 74 and the bracket 58 swung aside to the position shown in Fig. 5. The connector 82 is then inserted between the dies and the bracket 58 re-  leased so that a blade part 54 thereof fits into an indentation 84 of the connector to locate the latter in the correct position. The handles 34, 36, which are fitted with a ratchet device 42 as disclosed in Specification 661,192 are then squeezed to grip the connector. One wire is then inserted in the connector with its bared end reaching the indentation and the handles squeezed further to effect the crimping operation. The other wire is crimped to the other end of the connector in a similar manner. For crimping wires to the connector shown in Fig. 8 the bracket 58 is rotated clockwise to a position where it supports the lifted bracket clear of the dies. An upstanding lip of the bracket 58 in this position then forms an abutment for the shoulder of the connector when the latter is placed in position. Figs. 17-25 (not shown) illustrate a latch having a pin engaging in a cam slot in the bracket 48 and serving to prevent the crimping operation when the connector of Fig. 9 is not properly located. In a modification (Figs. 10-16, not shown) a pair of locating devices, adapted to function in manner similar to that shown in Figs. 1, 5 and 6, are associated with jaws which pivot about axes on a link and which are pivotally connected to a pair of operating handles.

Title: Diode memory matrix
IPC: G06F3/08
Filed: 1965-02-22
Abstract: 1,087,277. Semi-conductor diode matrices. BROWN, BOVERI & CIE A.G. Feb. 22, 1965 [March 13, 1964; March 14, 1964], No. 7592/65. Heading H1K. [Also in Division G4] The diodes of a matrix are formed simultaneously on a common insulating support. In a typical arrangement the columns of the matrix are formed by etching a titanium layer vapour deposited over one face of a glass substrate. Rectifying diodes of the matrix are formed on the columns by anodic oxidation at diode sites followed by vapour deposition of platinum electrodes. Platinum tracks connecting these electrodes in rows may be deposited at the same time or a different metal used for this purpose deposited subsequently, the tracks being insulated where they intersect the columns by lacquer or by a thick oxide layer on the columns. Each platinum electrode may be connected into a row by a link, including a constricted section. Selected diodes may then be permanently disconnected by passing a high current through the associated links to evaporate these sections. Alternatively each link includes a photoresistive element e.g. of cadmium sulphide whereby the diodes can be selectively connected by illumination through a card punched with holes indicative of information to be stored. In a further arrangement the platinum electrodes are associated with individual contacts selected ones of which may be connected into a row by engagement with a brush bar through holes in a punched card. In all cases the matrix is provided with a protective coating except at points where electrical access is required.

Title: An electrically maintained pendulum driven by gravitational impulses from a weight
IPC: G04C3/02
Filed: 1951-04-05
Abstract: 723,968. Clocks. WOOLDRIDGE, J. L. April 4, 1952 [April 5, 1951], No. 7928/51. Class 139. A pendulum is kept in oscillation by the repeated application, once per swing, of a vertical force derived from the weight of a piece of metal which during the application of the force is carried by two conducting projections on the pendulum from a higher position to a lower position in which it is received by two projections on a lever controlled by an electromagnet, the circuit of which includes the two conducting projections and the weight. The pendulum A, Figs. 1 and 2 is suspended from a support 1 by two strips 2a to each of which a projection 2 is fixed as shown. The projections 2 are electrically connected to an electromagnet 7 the armature of which is connected by a linkage 6 to a lever 4 which passes between the strips 2a and carries vertical projections 9. A weighted conducting metal strip 5 normally rests on the projections 9. When the pendulum approaches the end of its swing to the left, Fig. 1, the projections 2 engage the strip 5 and lift it from the projections 9. The conducting strip 5 bridges the projections 2 to complete the circuit to the electromagnet 7 which is energized to rock its armature whereupon contacts 8 are closed to send impulses to indicating mechanism and to lower the lever 4 and its projections 9 through the linkage 6. When the pendulum swings to the right it is accelerated by the weighted strip 5 until the strip again rests on the projections 9 when the circuit to the electromagnet 7 is interrupted and the armature restores the lever 4 to its initial "high" position.

IPC: C07F9/70
Filed: 1927-03-23
Abstract: 295,744. Newbery, G., and May & Baker, Ltd. March 23, 1927. Organo-arsenic compounds. - Oxyac,etic acid derivatives of arylarsinic acids are prepared from o-amino-oxyarylarsinic acids by first protecting the amino group, e,g. by introduction of an aryl group such as acetyl or benzoyl. and then treating the acid with an a-halogen-acetic acid or readily-hydrolysable derivative thereof, such as the amide or an ester. By hydrolysis of the product, the protecting group is eliminated and the o-substituted residues condense to form the corresponding isoxazine compound. The, latter may also be prepared without isolation of the intermediate product. According to the examples (1) 3-acetylamino-4-hydroxyphenylarsinic acid is condensed with chloracetic acid or chloracetamide; hydrolysis of the resulting 3- acetylamino-4-phenoxy acetic acid- or -phenoxyacetamide-1-arsinio acid yields 3-hydroxy-1 : 4- benzisoxazine-6-arsinio acid; (2) 3: 5-diacetylamino-4-hydroxyphenylarsinic acid condenses with chloracetic acid to give the corresponding phenoxy body, which, by hydrolysis, forms 8- amino - 3 - hydroxy-1 : 4-benzisoxazine-6--arsinic acid; acetylation of the latter gives the 8-acetylamino compound, which is described in Specification 278,444. Specification 280,613 also is referred to.
Patent GB-1094718-A (GB)
Title: High alpha-alumina fused cast refractories
IPC: C04B35/107
Filed: 1965-02-24
Abstract: A fused cast refractory article consists essentially of alpha alumina in the form of densely-packed crystals being substantially free of beta-alumina and contains up to 1 1/2 % of an alkali metal oxide and less than 1% of silica.  The article may have a density of at least 3.5.  The alkali metal oxide is preferably lithium oxide.  The fusion is generally carried out in a water-cooled iron shell and is effected by arcing between carbon electrodes riding above the bath and the bath, or by the resistance heating of the bath when electrodes are injected into it.  When sodium oxide is used the product is sensitive to the furnacing conditions and the electrodes are placed above the bath to prevent the incorporation of dispersed carbon into the product.  However, if lithium oxide is used the product is less sensitive to furnacing conditions and the desired crystal structure is obtained regardless of these. The product is mainly used for glass tank lining blocks but can also be used in metallurgical applications.
