Abstract: 692,691. Resilient mountings. MB MANUFACTURING CO., Inc. Aug. 8, 1947 [May 1, 1946], No. 22118/47. Class 108 (iii). In a vibration isolator unit comprising two members providing co-operating spaced load - carrying surfaces having a common axis, in combination with resilient means spacing the surfaces, radially straight lines along the average direction of the resilient means between the load-carrying surfaces taken at three or more points around the axis of the unit, each form with the axis an angle of 53.6 to 55.6 degrees, the stiffness of the resilient means in two directions at right angles to any such radial line and at right angles to each other being equal, whereby the unit is non-directional in character. In one embodiment, Fig. 3, the unit comprises a plurality of rubber elements 16 of substantially rectangular crosssection and preferably bonded between the faces of inner and outer concentrically-arranged members 10 and 14. The members 10 and 14 are provided with parallel inclined portions 12 and 15 respectively which form cone angles of 70.8 degrees on the longitudinal axis of the unit. In another arrangement, Fig. 4, the unit comprises a rubber element 26 having tubular portions 27 and 28 bonded to inner and outer tubular members 22 and 24 respectively, and having an annular portion or three or more uniformly-spaced elements 30 formed integral with the portions 27 and 28 such that the axes a of the sections of the portion or portions 30 form a cone angle of substantially 109.2 degrees on the central longitudinal axis of the unit. The portion 30 may be formed with a portion 31, overlapping a flange 25 on the tubular member 24 to act as a buffer against excess movements of the rubber towards an end member 32. The unit is secured to supported and supporting members by means of a bolt 34 and a bushing 36. The diameter of the opening in the member 32 for the bush 36 and that of an opening in a closure member 33 at the opposite end of the unit are each less than the diameter, of the flange 25. In a further embodiment Fig. 5, a rubber ring 54 of circular section, is engaged between corresponding conical surfaces 44 and 48 of a sleeve 40 and a spindle member 42 respectively. A second rubber ring 56 engages between a shoulder 43 on the sleeve 40 and a washer 52 on the spindle member 42. The rubber ring 54 which is preferably not bonded to the surfaces 44, 48 is pre-loaded during assembly of the unit and in operation of the latter under increased loading, the ring is deformed sufficiently until it bears on a curved surface 49 of the member 42. Thereafter, a higher load is required to produce succeeding movements of deflection in the ring 54. The Specification includes formulµ by which the cone angle required for non-directional characteristics of a unit, may be calculated from the stiffness values in three mutually perpendicular directions.

Abstract: 1,072,577. Fuel cells. UNION CARBIDE CORPORATION. May 29, 1964 [June 7, 1963], No. 22219/64. Heading H1B. A fuel cell electrode comprises .a porous conductive body having a first porous zone A, of a plurality of layers 11, 12, 13, which is electrochemically active and permeable to liquid electrolyte, and which extends inwardly from one surface of the body, each of said layers being more electrolyte-repellent and less electrochemically active than the next outer layer adjacent thereto, and an adjacent second porous zone B, which is a layer 14 entirely repellent to liquid electrolyte and gas-permeable and extends inwardly from another surface of the body. The electrolyte-repellent zone B is powdered graphite or an inactive metal powder, and this layer 14 has a metal mesh 15 as support or current collector. Activated carbon is used in layers 11, 12, 13, the particles increasing in size towards layer 14, and the layers increasing their content of thermoplastic binder similarly. The active zone A may be a mixture of powdered graphite and alumina, with an appropriate catalyst in the case of hydrogen electrodes, while zone B may be a sintered metal plaque. The electrode is alternatively treated with a wetproofing agent, which is removed selectively, leaving less in zone A and more in zone B by several methods such as vacuum distillation or leaching, to leave zone A active but with a gradient of electrolyte repellency increasing towards zone B, which is electrolyte-repellent. Zone A is pretreated with sodium carboxymethylcellulose to prevent adherence of the wetproofing agent thereto, and pre-cleaned by a vacuum heat treatment.

Title: New derivatives of heparin and processes for their preparation
IPC: C08B37/10
Filed: 1961-06-20
Abstract: Heparinamide or N-alkyl heparinamide as the free sulphonic acid or an alkali or quaternary ammonium salt (claimed per se) is produced by amiding a C1- 6 alkyl ester of heparin or a mixed anhydride produced by the interaction of a long-chain alkyl or aralkyl C9-27 quaternary ammonium salt of heparin and a C1- 6 alkyl chlorocarbonate. Heparinamide may be produced by reacting an alkali metal salt of the ester with ammonia in the presence of water and purified by intermediate formation of the "Hyamine 1622" salt.  N-alkyl heparinamide may be similarly produced using a primary alkylamine in the presence of formamide or water.  The amine may be methyl-, ethyl-, propyl-, isobutyl-, or tertbutyl-amine.  Amidation may be effected at -30 to 25 DEG C.  It may be 60-95% complete.  N-methyl heparinamide may alternatively be produced by treating the "Hyamine 1622" salt of heparinamide with diazomethane in methyl chloride solution.  In a further alternative, it may be produced by reacting the "Hyamine 1622" salt of heparin with ethyl chlorocarbonate in tetrahydrofuran containing a small amount of water and reacting the intermediate product with methylamine. Specifications 904,112, 973,894 and 973,895 are referred to.

Title: Control arrangement for facsimile apparatus
IPC: B41L47/42
Filed: 1950-09-18
Abstract: 693,577. Copying telegraphy ; local copying by scanning. EASTMAN KODAK CO. Sept. 18, 1950 [Sept. 17, 1949], No. 22828/50. Class 40 (iii). In facsimile apparatus in which scanning means is driven by a first motor, the matter to be transmitted or the medium on which the recording is effected is fed past the scanning means by second motor which is not energized until a short time after the first motor has been started into operation. The arrangement shown includes a scanning drum 10 with multiple helical slots 16, 16 and a reproducer having a drum 11 with multiple helical ribs 41 associated with separate printer bars 31, 38, 39, 40, the apparatus being generally similar to that described in Specifications 693,576 and 693,578. The outputs of the four photo-electric cells 25 ... 28 of the transmitter are applied to amplifiers 29, 32, 33, 34 connected to the respective printing bars. On operation of the starting switch 45 a condenser 46 is charged and makes the right-hand section of a double-triode 50 conducting so that a relay 51 is operated, closing contacts 43 which connect the scanning motor 13 to the supply mains 42. At contacts 52, a condenser 53 is connected to the bus-bar 48 and is charged after a short interval to an extent sufficient to make conducting the lefthand section of the double-triode 50. Relay 56 is operated and at contacts 44 connects the feeding motor 81 to the supply 42. At contact 57 a charging circuit, alternative to that provided by switch 45, is closed to maintain the condenser 46 in the charged condition. During picture transmission the signals from the amplifier 29 are fed via condenser 61 to the right-hand section of a rectifier valve 63 so that the right-hand section of a double triode 67 is held non-conductive. If signals fail, valve 67 conducts and energizes relay 68, opening the circuit of the condenser 46 which discharges and renders the right-hand triode of the double triode 60 non-conducting so that relay 51 releases and opens the circuit of the motor 13. Relay 56 is released almost immediately and opens the circuit of the feeding motor 81. The respective left-hand sections of the rectifier 63 and double triode 67 are similarly controlled by the output of the amplifier 32, and a further double triode and rectifier, indicated by the block 72, may be controlled by the outputs of the amplifiers 33, 34.

Title: Electro-pneumatic control means
Inventor: WORSWICK BERNARD AUGUSTINE
IPC: F15B21/08
Filed: 1956-07-24
Abstract: 842,978. Automatic control systems. BAILEY METERS & CONTROLS Ltd. July 24, 1957 [July 24, 1956], No. 22844/56. Class 38 (4). In a system in which a member movable in dependence on a variable electrical quantity varies the incidence of radiant energy on a radiation-sensitive device controlling a fluidpressure regulator, negative feed-back is also applied directly from the regulator in a manner tending to restore the incidence of radiation. In Fig. 1 a pointer 1 of an electrical moving coil instrument responsive to change in a variable to be controlled carries a vane 3 which, when pointer 1 and a tubular arm 4 are parallel, extends downwardly into a slot 5 in arm 4 so that a photo-transistor 11 is partly masked from light from a lamp 7 located on the axis 2 about which pointer 1 and arm 4 may move. In this condition an electromagnetic relay 13 controlled by the photo-transistor is not operated and fluid pressure is applied through a valve 18 to an element 23 controlling the variable and to an adjustable negative feed-back device 26 acting on arm 4. If the variable deviates so that pointer 1 moves clockwise the photo-cell is unmasked, the relay 13 operates, and valve 18 shuts off the air supply and exhausts the pneumatic system to atmosphere, causing element 23 to correct the variable and device 26 to apply negative feed-back. In a modification, Fig. 2 (not shown), integral and derivative control terms are introduced into the pneumatic system. To avoid overheating of the photo-transistor a further transistor may be arranged to form a bi-stable circuit for operating relay 13. Specifications 425,507 and 802,598 are referred to.

Title: Improvements in perforating machines
IPC: B26F1/24
Filed: 1946-07-31
Abstract: 615,178. Perforating machines. ABBEY, A. (Handels-Och Fabriksbolaget Hjalmar Andren). July 31, 1946, No. 22858. [Class 31(ii)] In a machine for perforating stencils for patterning fabrics having a vertically reciprocating slide carrying a punching needle 17 and a presser-foot set against the stencil 3 and displaceable to advance the stencil, the presserfoot is adapted to be raised from the stencil by the needle slide. As shown in Fig. 1, the presser-foot 9 is vertically guided by pins 10 in a member 8 slidable laterally on pins 7 on a bracket 6 carried by a handwheel 5 mounted on the arm 1 of the machine. A lever 16 pivoted at 15 to the member 8 engages a pin 13a on the foot 9 and also engages the lower end of the needle bar 4 so that when the latter is depressed, the lever is actuated, raising foot 9 against the downward pressure of springs 11 on the pins 10. The upward stroke of the needle first allows the spring 11 to lower the foot on to the stencil and then a cone 18 on the bar 4 engaging a wedge 19 on the slide 8 moves the slide and the foot 9 to feed the stencil 3. A crank lever 20 coacting with a slide pin 21 restores the slide 8 at the end of the next downward movement of the spindle by engagement of the lower arm of the crank lever with the lever 16. Adjustment of the length of the feed may be effected by replacement of the wedge 19 or by radial adjustment of the bracket 6 on the handwheel 5, which may be rotated on the machine arm 1 to cause the needle to follow the pattern on the stencil.
