Title: Improvements in or relating to bonded articles such as abrasive wheels, and methods of making them
IPC: B24D18/00
Filed: 1931-12-28
Abstract: 394,667. Moulding grinding-wheels &c. CARBORUNDUM CO., Ltd., Trafford Park Road, Manchester.-(Carborundum Co.;: Niagara Falls, New York, U.S.A.) Dec. 28, 1931, No. 35836. [Class 87 (ii).] Relates to a process for securing uniformity in the structure of a bonded article such as a grinding-wheel. The mixture of grinding- material, bonding-material and water, is supplied to a mould, preferably a rotating mould, in small uniformly distributed portions, e.g. a volume not exceeding one cubic centimetre or fifteen times the average volume of the coarsest kind of grain in the mix. The division of the wet or damp mix into small portions may be effected by a shaking screen, the mesh of which does not exceed five times the average size of the grains. The uniformity of the grinding-wheel is further assured by making it under controlled humidity conditions in a chamber to which a spray is introduced by an injector. The control is effected by a wooden block which expands or contracts under varying humidity conditions and adjusts the injector valve accordingly. The mould is jolted, after charging, whilst subjected to a. light preliminary consolidating pressure, and the material is afterwards subjected to the heavier final compression. As shown, the mould 3, 4, 5 is carried on a turntable 10 positioned beneath a vibrating frame 7<1> carrying the screen 8 and, if desired, one or more additional screens 9. The screen 8 is larger in area than the mould to ensure uniformity of charging. The light preliminary pressure is applied by a single weight 43, Fig. 3, or by a number of nested smaller weights which accommodate themselves to surface irregularities, or an inflatable bag 27, Fig. 6, may be used for more perfect accommodation. The nested weights may be placed on a closed air cushion. The jolting may be effected pneumatically either in a vertical direction or in two horizontal directions at right-angles, or both vertical and horizontal jolting may be used. The mould 3 is placed on the shaking table 10 which has a central stem working in the pneumatic cylinder 13. The horizontal jolting is effected, in two directions at right - angles, by plungers 21 associated with cylinders 22 and guided by stops upstanding from the table 10. Spring buffers bear on the sides of the mould. Before the application of the final pressure, the ring 4 is removed from the mould and the material is strickled. A test for uniformity is described, comprising impregnating the wheel with the material known by the Registered Trade Mark " Bakelite," heating to harden the " Bakelite " and grinding and polishing the surface. Definite areas of the wheel are then examined by a reticulated microscope and estimates made of the spaces in each area occupied by grinding-particles, bonding-material and pores.

Abstract: 662,842. Automatic steering control systems. BENDIX AVIATION CORPORATION. Dec. 6, 1946 [Jan. 31, 1946], No. 36139/46. Class 38 (iv). In an automatic pilot of the type in which rudder, elevator and ailerons are moved by individual electric motors via electromagnetic clutches in response to the amplified resultant of an error signal and a reference signal, a manually-controlled signal is added to control the appropriate control surface. Rudder.-The rudder 10, Fig. 1, is driven through a magnetic clutch 45 by a two-phase servomotor 43 having the controlling winding 42 energized from an amplifier 40 according to the resultant of direction signals from an earth inductor compass 11, follow-up signals from a gear driven transmitter 48, and, in series with the follow-up transmitter, rate-of-turn signals from a transmitter 57 coupled to a rate-ofgyroscope 51, manual turn control signals from a potentiometer 110 across a centre tapped transformer 115, and manual trimming control signals from a potentiometer 138 across transformer 139. The signals from the compass are fed by way of a transmitter 29, the rotor 30 of which, during straight automatic flight, is locked by a solenoid brake 125 so as to transmit signals to the amplifier 33 for connection to the servo-amplifier 40. During a manually initiated turn under automatic control, switch 127 is opened to de-energize solenoid 125 and release servomotor 36 which turns rotor 30 to nullify compass signals which would otherwise attempt to correct the deviation. During fully manual flight, the master switch 129 is opened to deenergize both the brake 125 and the clutch 45. Elevators. The elevators 87, Fig. 2, are actuated through a magnetic clutch 98 by a servomotor 96 energized by an amplifier 92 according to the resultant of attitude signals from transmitter 88 coupled to one axis of an artificial horizon gyroscope 64, in series with follow-up signals from the gear-driven transmitter 101, manual control signals from potentiometer 112 and transformer 117, and manual trimming control signals from a potentiometer 153 across transformer 151. The manual control 112 is arranged so that movement of the slider in either direction from the mid-point raises the elevators to compensate for the nose of the aircraft dropping during a turn. The magnetic clutch 98 is energized by the master switch 129. Ailerons.-The ailerons 70 are similarly actuated through a magnetic clutch 82 by a servomotor 80 in accordance with the resultant of attitude signals from the artificial horizon transmitter 71, follow-up signals from transmitter 84, manual bank control 111 and a manual trimming control 148. The three manual controls 110, 111, and 112 may be ganged. Specifications 662,831, 662,832, 662,839, 662,843 and 662,860 are referred to.

Title: Process for producing antibiotic material
IPC: C07H19/06
Filed: 1972-08-02
Abstract: 1355734 Antibiotics aspiculamycin and ioyocamycin SANKYO CO Ltd 2 Aug 1972 [3 Aug 1971] 36175/72 Heading C2A In a process for producing antibiotic material by cultivating Streptomyces toyocaensis var. aspiculamyceticus strain no. 1040 in an aqueous nutrient medium, the novel antibiotic aspiculamycin having the formula and also the known antibiotic toyocamycin and an antifungal tetraene antibiotic are co-produced in the medium. The cultivation is performed under aerobic conditions at 25 to 35 C. and approximately neutral pH. The medium contains conventional assimilable carbon and nitrogen sources and inorganic salts, and maximum production of antibiotic material takes 40 to 120 hours. After cultivation, the culture is filtered, brought to acid to neutral pH and passed over a cation-exchange resin or treated with activated carbon, when the aspiculamycin is adsorbed, the toyocamycin may be adsorbed or not according to the nature of the resin, and the tetraene is not adsorbed. Aspiculamycin is then eluted with aqueous acid, alkali or inorganic salt in the case of the resin, or with acidified aqueous methanol or aqueous acetone in the case of the carbon. Toyocamycin adsorbed on the resin may be eluted at a lower pH. The eluates are de-ionized and concentrated, the aspiculamycin being finally isolated by precipitating with a miscible non-solvent (e.g. acetone) or by lyophilization. It may be converted into its acid-addition salts by conventional means. Aspiculamycin and its acid-addition salts have anthelmintic activity and weak antibacterial activity, and may be used in pharmaceutical compositions together with a pharmaceutical carrier or diluent.

Title: Improvements in or relating to windshield wiper assemblies
IPC: B60S1/38
Filed: 1954-12-16
Abstract: 790,775. Windscreen cleaners. PRODUCTIVE INVENTIONS, Inc. Dec. 16, 1954 [April 21, 1954], No. 36446/54. Class 138(1). A windshield wiper arm 1, Fig. 2, connectible to a drive shaft 5 and carrying a wiper blade assembly 2, is provided with a member 17 movable relative to the arm 1 to forcibly tilt the assembly 2 relative to the arm 1 about the longitudinal axis of the blade or about an axis parallel to that axis, during a predetermined portion of the travel of the blade. The drive shaft 5 is carried in a mounting 6, and the wiper arm 1, has an inner section 4 secured to the shaft and an outer channel section 7 pivoted at 8 to the section 4. A wiper arm pressure distributing structure, formed of a primary yoke 12 and secondary yokes 11, is connected to the wiper blade formed of a wiper element 9 and backing support 10. The primary yoke 12, Fig. 7, has secured thereto a channel connector 13, the sides 14 of which are apertured at 15 to receive projections 23 of the member 17 pivoted by a rivet 18 to a member 16 secured to the arm section 7. The rivet is disposed in downturned offsets 19, 21 of the members 16, 17, whilst portions 20, 22 thereof are provided with cam slots having normally aligned portions 24, 26, Fig. 6, and crossed portions 25, 27, respectively. Disposed in the slots is a cam follower 29 the head 28 of which abuts the lower surface of the member 17 whilst the shank is connected to one end of a spring rod 30, the other end of which is pivotally connected to a plate member 31, Fig. 2, adjustably secured to the mounting 6. With the cam follower in the position shown in Figs. 6 and 7, the member 17 is prevented from rotation since the follower is engaged in the slot portions 24, 26 so that the wiper blade will be positioned relative to the arm 7 as depicted in full lines in Figs. 4 and 5. As the arm oscillates to the position 34, Fig. 5, the follower will move out of the slot portions 24, 26 and enter the slot portions 25 of the member 16. Since, the follower then also engages in the slot portion 27 of the member 17 the latter pivots relative to the member 16 as the arm moves to the position 35 on the "wrapped-round" wing portion 33 of the windshield, and the angle between the longitudinal axis of the blade and arm is increased. Owing to the pivotting of the offset 21 relative to the offset 19 the blade 9, 10 and its superstructure is also tilted relative to the offset 19. The blade is thus maintained substantially normal to the windshield as shown at 38, Fig. 4. The members 16, 17, follower 29 and rivet 18, are enclosed in a shroud 32, Fig. 7.
