Abstract: 1,224,512. Gyroscopic apparatus. TOKYO KEIKI SIEZOSHO KK. Oct. 7, 1968 [Oct. 7, 1967], No.47413/68. Heading G1C. In a gyroscopic instrument in which the gyro spin axis is to be maintained at a predetermined attitude, e.g. a gyrocompass or gyrovertical, an arrangement is provided for generating an electric signal corressponding to the integral of the angle of tilt of the spin axis to the desired attitude, this signal being used to correct the attitude in addition to a normal servosystem using accelerometers for example, to correct for mass-unbalance errors and in the use of gyrocompass for latitude error, the integral signal being derived by use of a sealed container containing a fluid therein and leaving a bubble, the movement of the bubble under the tilting action of the spin axis producing the desired electrical signals. Fig. 6 shows a gyrocompass having a rotor spin axis As B 2  and an accelerometer unit U 2  for detecting tilt of the spin axis about a horizontal axis at right angles thereto. The accelerometer output is phase-discriminated in an A/C bridge circuit 215 amplified by an amplifier 216 and fed to a torquer 219 by way of a mixer circuit 218. In prior arrangements correction for latitude error has been provided by use of an integrator circuit for the accelerometer output and connected to the mixer circuit 218. In the present invention a unit U 3  is provided responsive to tilt about the same axis as the unit U 2  and the unit U 3  is a sealed container giving an electrical output in accordance with the integral of the sensed tilt as refered to above. The output of the unit U 3  is fed through circuits 215<SP>1</SP>, 216<SP>1</SP> to the mixer circuit 218. In the case of the gyrovertical, two accelerometers are used to detect tilt about two orthogonal horizontal axes, and correspondingly two integral signal producing units, these latter two being combined into a single sealed container with a bubble and a flat upper surface and two sets of sensing electrodes in alignment with the two horizontal axes. If desired the bubble may be replaced by a ball of magnetic material whose position is detected electromagnetically.

Abstract: 1397818 Sintering iron-base-alloys ALLMANNA SVENSKA ELEKTRISKA AB 17 Oct 1972 [18 Oct 1971] 47778/72 Heading C7D Iron-base alloy powders are isostatically hot pressed in two stages, one stage at a temperature such that at least 25% of the alloy is α-phase, the other at a temperature such that the alloy is substantially completely in the γ-phase. It is preferred to effect the α-phase heating first, but if the reverse order is adopted an intermediate cooling stage to below the α-phase temperature is incorporated. Typical temperatures are 700- 950 C for the α-phase and 950-1225 C for the γ-phase heating. It is stated that such a process avoids the need for subsequent forging or rolling to obtain desired degree of compaction. Preferred apparatus is similar to that disclosed in Specification 1299043, and includes apparatus for an initial isostatic cold-pressing operation.

Abstract: 1,203,509. Thermal switches. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 10 Oct., 1968 [16 Oct., 1967 (3); 6 Feb., 1968 (2); 7 Feb., 1968; 12 Feb., 1968], No. 48037/68. Heading H1N. The response temperature of thermally responsive bi-metal actuated switches is controlled by varying the current in a solenoid 78, Fig. 6, so that the magnetic flux influences the movement of the contacts 68, 72. In the arrangement shown the moving contact 68 on a spring blade 67 is thermally actuated by a bimetal strip 63 through slotted insulator 64. The normally fixed contact 72 is mounted on a spring blade 71 carrying a magnetic plate 73 influenced by the solenoid 78 from a coaxial polepiece 76. A resilient member 79 of rubber or PVC is arranged between the polepiece 76 and the plate 73. In other examples the solenoid may be mounted on the bi-metal element or fixed contact and may influence either the fixed or movable contact, either of which may be of magnetic material or carry a plate of magnetic material. In a further modification a magnetic bi-metal contact strip 132, Fig. 13, may be mounted in a hermetically sealed capsule of non-magnetic material and surrounded by a solenoid 134. Terminal plates 137, 138 may be hermetically sealed to a bobbin 131 and the inside space may be evacuated or gas-filled.

Filed: 1972-10-18
Abstract: 1374715 Pile driving B LUDVIGSON 18 Oct 1972 [18 Oct 1971] 48084/72 Heading EIH In order to regulate the impact force transmitted from a drop hammer 1 to a pile 3, Fig. 3, a resilient adjustably deformable pile cap is located between the hammer and pile and comprises a piston 5, impacted by the hammer, acting on a volume of compressed gas, the pressure of which is adjusted by a piston 7 positioned by transfer of liquid between spaces 10 and 12. The transfer of liquid is controlled by a valve 13 and non-return valves 14. The drop height and the gas pressure are selected to maximise the driving efficiency. In a modification, Fig. 4, the valves are replaced by a reversible pump 23, and the piston 5 is depressed (by a pump 19 supplying liquid to a space 21 prior to hammer impact), by an amount equal to the calculated distance the pile 3 will be driven by one impact. The piston 5 cooperates with a ring 17 which separates from piston 5 on initial impact and is biassed by a spring 22 to allow the piston 5 at the end of the impact to return to its original position and thus provide a lifting force sufficient to raise the hammer 1 to its original position. In another arrangement, Fig. 5, the piston has a plurality of lateral ports 27 controlled by a valve ring 26. The piston is biassed by pumping fluid from chamber 12 to chamber 21. Upon impact of the hammer 1, the ports 27 will be opened and the gas in the piston can escape to chamber 21. The plate 28 will, on initial downward movement of the piston, seal against the bottom thereof and a temporarily increased force will be transmitted to the pile. The piston may be initially biassed by pumping in liquid from an external reservoir surrounding the cap, Figs. 6, 7 (not shown) and during the latter part of the impact, when the piston is rising relative to the remainder of the cap, liquid will return to the reservoir via non-return valves.

To open the door 3 an operating knob 9 is operated to release locking devices 10/15 and 11/17 associated with a rod 8 which extends through the rail 7, after which the door 3 is pivoted about a vertical axis into an intermediate position the vertical axis being constituted by the pivotable engagement of the supporting arm 18 with a bracket 16 fixed to the vehicle body 1 and in its final pivoting position the arm 18 is held by a stop 25 on an associated control rod 24. The door may then be opened by sliding it rearwardly, the rail 7 moving through the guide 19 during this sliding movement. The control rod 24 is connected to the bracket 16 and the guide 19 so as to be pivotable about pivotal axes which are not coincident with the pivotal attachment points of the supporting arm 18. A draw spring 26 prevents the door from swinging back from its final pivoted position, and the pivoting movement is aided by engagement of a guide bar 29 secured to the vehicle body 1 and a guide arm 30 with a roller at its end secured to the door 3. As indicated in Figure 3 a motor drive can be provided for opening and closing the door-an electric motor 31 with gearing 32 is fixed to the guide 19 and engages via a gear wheel 33 with a toothed rack 34 on the lower edge of the guide rail 7. The door 3 has a window and a cover 13 which covers the guide rail 7 and constitutes an arm rest, may have recesses for window lifting devices. Stops may be provided which engage with corresponding counter stops or pins forming the swivel axes of the supporting arm 18 and guide 19, and the guide rail 7 may carry a pawl which engages with a notch on the guide 19 when the door 3 is open.

Abstract: 1,199,479. Linear motors. ELECTRICITY COUNCIL. 22 Oct., 1968 [23 Oct., 1967], No. 48114/67. Heading H2A. [Also in Division E2] A linear motor for operating a door comprises an alongated armature 12 on which is wound a coil 13 energized with D.C. through brushes mounted on a surrounding field assembly 20. As shown, the field assembly has four poles 21 . . . 24 with three energizing coils 25 and the armature has three brushes 15 . . . 17 contacting bored portions of the winding and connected so as to energize the intermediate portions of coil 13 in opposite senses, which portions then co-operate with the appropriately energized poles to produce motion in one direction or the other. Reversal of motion is obtained by reversing either the field current or armature current. The armature may be circular and supported on rollers or generally rectangular and slidable on P.T.F.E. a block (Fig. 5, not shown). The circular armature may rotate as it slides to ensure even brush wear on the coil. Either the armature or the field assembly may be coupled to the door and in the latter case connection to the motor may be effected by sliding contacts engaging conductor rails, by trailing leads or by flexible leads extending through a pivoted arm. The motor may be stopped by limit switches at each end of the stroke and further limit switches may be provided for increasing the field current and reducing the armature current near each end of the stroke so as to slow down the motor. A reversing switch may be operated by a rubberfaced strip on the leading edge of the door if the door meets an obstruction.

Abstract: 1,273,908. Siloxane block copolymer. DOW CORNING CORP. 13 Oct., 1970 [1 Dec., 1969], No. 48564/70. Heading C3T. A room temperature vuloanizable (RTV) composition stable in the absence of moisture and curable upon exposure to moisture comprises an organisoloxane block copolymer which comprises: (A) 16-84 mol per cent of diorganosiloxane units wherein the units are bonded through Si-O-Si bonds forming a block having 6-350 units/block, the polydiorganosiloxane being at least 80 mol per cent dimethylsiloxane units and any remaining units being phenylmethyl- or monomethyl-siloxane units; (B) 11 to 77 mol per cent organosiloxane units R x SiO( 4-x)/2  where x = 1-1À3, R is aryl, C 1 _ 3  alkyl, or vinyl, at least 50% R being aryl, the units comprising a block of at least 3 units which are mono- or diorganosiloxane units; and (C) from 2-27 mol per cent terminating acetoxysiloxane units R<SP>1</SP>Si(OCOCH 3 ) y O 3(-y)/2  where y = 1À8-2, R<SP>1</SP> is a C 1 _ 5  alkyl, phenyl or vinyl radical. The hydroxylated block copolymer can be prepared by coupling and cohydrolysing the hydroxyl terminated polydiorganosiloxane (A) with a trifunctional organosilane in the proper proportions. Thus in a specific example a mixture of C 6 H 5 SiCl 3 , C 6 H 5 CH 3 SiCl 2  in toluene is added to a mixture of hydroxyl-terminated polydimethylsiloxane, toluene, HCl and H 2 O with stirring and then azeotroped to remove residual HCl and H 2 O. In an alternative method the hydroxylated block copolymer is made by coupling the hydroxyl terminated polydiorganosiloxane (A) with an aromatic containing organosiloxane resin (B) having hydroxyl groups, by reaction with a trifunctional silane under anhydrous conditions. The coupling can take place in the presence of amine catalysts such as pyridine, alphapicoline and n-butylamine. The resulting block copolymer produced by either method is then reacted with the monoorganotriacetoxysilane (C) to yield the RTV composition. Reactive diluents such as acetoxy silicon compounds particularly R<SP>1</SP>Si(OCOCH 2 ) 3 , or non-reactive diluents such as organic solvents can be added to the composition to control the extrusion rate. The compositions can be used as release coatings and adhesives. Substrates which can be bonded by the compositions include glass, ceramics, metals such as Al, steel and Cu, wood, paper, thermoplastics, cellulose aectate-butyrate and leather.
