Title: Process for the Perorganylation of Lead and Antimony Salts
Inventor: MULLER RICHARD
IPC: C07F9/90
Filed: 1967-06-06
Abstract: 1,196,621. Organo lead, and antimony compounds. INSTITUT FUR SILIKON-UND FLUORKARBON CHEMIE. 6 June, 1967, No. 26078/67. Heading C2J. Organo lead and antimony compounds in which all the valencies of the metals are attached to organic radicals are prepared by directly reacting an organo tri-fluoro silane under anhydrous conditions with a Pb or Sb salt or partially organylated Pb or Sb salt, in the absence of an organo fluoro silicic acid or salt thereof, an alkali metal or ammonium fluoride and an acid forming an organo fluoro silicic acid. Reaction is usually effected at elevated temperature and may be in the presence of an organic solvent, e.g. glacial acetic acid or ether. In Examples (1) (C 6 H 5 ) 3  PbF reacted with C 6 H 5 SiF 3  yields (C 6 H 5 ) 4 Pb; (2) (C 6 H 5 ) 2  SbF reacted similarly yields (C 6 H 5 ) 3  Sb which is reacted with Cl 2  to form (C 6 H 5 ) 3  SbCl 2 ; (3) (C 6 H 5 ) 2 SbF reacted with Cl 3 C.SiF 3  yields (C 6 H 5 ) 2 Sb.CCl 3 ; (4) SbF 3  and Cl 3 C.S.F 3  yield (Cl 3 C) 3 Sb; a large excess of SbF 3  with the Cl 3 C.SiF 3  or its precursor Cl 3 C.SiF 3  results in a similar product with some of the chlorine replaced by fluorine; (5) lead tetra-acetate and C 6 H 5 SiF 3  yield tetra stenyl lead. Specification 1,134,933 is referred to.

Abstract: 821,090. Electrically heated printing screens. DRY SCREEN PROCESS Inc. Aug. 19, 1957 [Aug. 20, 1956], No. 26092/57. Class 39(3) [Also in Group XVI] In a screen printing device using thermoplastic printing composition the screen is made of stainless steel cloth and heated electrically so as to maintain the printing composition at a high enough temperature for printing. The cloth is woven e.g. from 0.0019 wire, and is stretched across an aluminium angle bar frame 18 to form the screen 13. The sides of the screen are stitched to strips 19, Fig. 9, of light canvas or duck which is crimped into galvanized angle strips 20 for drawing the screen taut upon the frame 18 by adjustment of bolts 21. At the ends the screen is soldered to crimped galvanized angle strips 22, Fig. 8, which are bolted to aluminium bus-bars 23. The bus-bars deliver a controlled low voltage, variable high amperage heating current to the screen from a power source connected thereto through cables 24 and straps 25. A rubber grommet 26 located around the bottom inside edge of the frame 18 insulates the screen from this frame. Since the expansion of aluminium when heated is slightly greater than that of stainless steel cloth the tautness of the screen is slightly increased as it is heated. The frame 18 is supported by dielectric mounting tabs 17.

Title: Adjusting device for servo brakes, in particular for motor vehicles
IPC: F16D65/56
Filed: 1954-09-09
Abstract: 753,554. Internal shoe - drum brakes. PORSCHE, F. Sept. 9, 1954 [Nov. 28, 1953], No. 26123/54. Class 103 (1). In a servo brake, the floating brake shoes are supported indirectly through an adjustable abutment by means of two separate arms of different length which can swing round a common point of rotation. In the embodiment illustrated, the primary shoe 5 and the secondary shoe 6 are expanded against the action of return springs 7 by an expanding device 2 secured to the brake carrier plate 1. The shoes 5 and 6 are supported by means of arms 9, 10 and an adjustment device 11, having an adjusting nut 12 and adjusting screws 13, 131. The latter screws are provided with semispherical heads 15, 15<SP>1</SP> having two parallel flat surfaces to prevent rotation and are situated in complementary holes 17, 171 in the arms 9 and 10 respectively. Arm 9 is provided with forked extensions 21, 22 which serve as anchors for the lower return springs 7, and the arms 9 and 10 pivot on a pin 18 fixed to the brake carrier plate and are bent over towards the axis of the adjustment device 11 and are provided with curved application surfaces 20, 20<SP>1</SP> with which slide blocks 8, attached to the brake shoes 5, 6 are in contact. The arm 9 is shorter than the arm 10 so as to ensure that the force transmitted from the primary shoe 5 to the secondary shoe 6 is approximately half the force developed in the primary shoe 5 to ensure uniform wear of the brake linings 3 and 4. During braking action, servo action of the brake is obtained as the arms 9, 10, including the adjustment device 11, swing radially round the pin 18 corresponding to the direction of rotation. R. When braking ceases, the shoes are moved to their release position by return springs 7 and are straightened up through the arms 9 and 10 by a centralising spring 26. Adjustment of the brake shoes is achieved manually by turning the adjusting nut 12. A further embodiment is described in which automatic adjustment for brake lining wear is provided in the form of a ratchet and pawl mechanism.

Title: Processes for reforming hydrocarbons
Inventor: MACCORMAC MICHAEL
IPC: C10K3/00
Filed: 1961-07-19
Abstract: Gaseous or volatile hydrocarbons are reformed by partial combustion to carbon monoxide and hydrogen in a process which comprises mixing the hydrocarbon in the vapour phase with steam and oxygen to produce a first mixture which contains sufficient free oxygen to propagate flame and sufficient steam to ensure that combustion takes place without the production of significant amounts of free carbon or tar, and initiating and maintaining continuously the combustion of the first mixture by means of a pilot flame maintained by a small quantity of a second mixture containing an excess of combustible material but sufficiently aerated to give a stable stationary flame, whereby the hydrocarbon in the first mixture is reformed.  The second mixture may be prepared by adding further oxygen to a portion of the first mixture.  In Fig. 1, the first mixture is fed to the combustion zone 11 via flame trap 15, which is surrounded by pilot burners 16. Fig. 3 shows an alternative construction, the <PICT:0969528/C4-C5/1> <PICT:0969528/C4-C5/2> first mixture entering via flame trap 34 having a subsidiary pilot burner 37 in its centre, some of the first mixture being mixed with air from 41 to an annular pilot flame 42-43.

Title: Capacitor storage circuits using field-effect transistors
IPC: H03G1/02
Filed: 1969-05-23
Abstract: 1,260,336. Analogue voltage storage circuits; remote control of receivers. RCA CORPORATION. 23 May, 1969 [31 May, 1968], No. 26396/69. Headings H3Q and H3T. The conductivity of an insulated gate of a field effect transistor 10 (Fig. 1) is controlled by connecting the gate through a switch 30 to a source of variable potential 12 and to a capacitor 14 which may be charged according to a control potential via further switching means (e.g. 20- 26). Fig. 2 shows a remote control arrangement for a television receiver in which the voltage across a storage capacitor 124 controls the gain of the audio circuit of the receiver and in which similar capacitor circuits may provide remote control of colour and tint. Charging and discharging of the capacitance is controlled by a supersonic link the amount of charge or discharge being dependent upon the time a control button is pressed and thus the time a corresponding frequency is emitted. The remote control receiver comprises a microphone 182, a pre-amplifier 184 and a further amplifier 186. The output of this is supplied via transformer 190 to secondary circuits 230, 236 tuned respectively to negative charge and positive charge control frequency signals. The signal breaks down a corresponding gas diode 130, 132 and this allows a charge or discharge current to flow to the storage capacitor 124 via 206 or 208 from a supply 160 or 200 comprising a rectifier and silicon stabilizing diodes. The voltage across the storage capacitor controls the conductivity of a field effect-transistor 114 and thus the gain or other variable. The remote control circuit may be switched off by a further transmitted frequency selected by a circuit 262, 264 and amplified at 256 to operate a relay contact 252 in the supply circuit 150 for stages of the control circuit. Local control is effected by a potentiometer 152 coupled to a switch 154, 156 such that any movement of the potentiometer closes the switch to operate a relay 138, contact 134 of which shorts the storage capacitor 124 so that the desired level is achieved with no charge in the capacitor.

[Classes 80 (ii) and 80 (iii).] A shaft 2, Fig. 1, is driven alternately by two one-way mounted pinions 16 which engage two toothed segments 12 which are rocked about a driving-shaft 1 by variable-throw cranks 15 in opposite phase. Crank blocks 11 are guided to slide radially on the faces of loose gears 5 driven constantly from pinions 4 fast on the shaft 1. A recess in each block 11 is engaged by a pin 15 protruding from a block 14 which slides, as the gear 5 rotates, in a slot 13 in each segment 12. Each crank block 11 is connected to a central plunger 23 by a bell crank 53 pivoted at 58 to the gear 5. The plungers 23 are operated together towards and from one another to vary the amplitude of oscillation of the alternately-acting segments 12 and thereby to vary the speed of the one-way driven shaft 2. The plungers 23 are for this purpose connected to two racks 56 which engage on opposite sides a pinion 54 which is turned by a control handle 55. The Specification as open to inspection under Sect. 91 comprises also an arrangement with a single variable-throw crank 15, Fig. 1 (Cancelled), and segment 12. A gear train 19, 21 is arranged to give on the back stroke of the segment 12 an additional equal impulse to the shaft 2. The crank block 11 is slid inwards and outwards in a guide 10 upon the gear 5 by the effort of the engine. The block 11 is formed on its rear face with a scroll engaging a scroll on the face of a gear 8 fast on a shaft 7 on which the hollow gear 5 turns being driven from a pinion 4 fast on the shaft 1. The shaft 7 carries a cone 28 and a gear 32, the latter meshing with a gear 33 loose on the shaft 1 and larger than the gear 4.
