Abstract: 892,418. Automatic speed-control systems. FERRANTI Ltd. July 13, 1959 [July 14, 1958], No. 22435/58. Class 38 (4). The work-table 10 of a machine tool is driven to the right at a steady velocity in response to a control signal applied over line 32 to a device 31 which compares the control signal with one provided by tachometer generator 34 and affords an error signal over line 35. When clutch 16 is engaged, the table is driven by actuator 11, a valve 15 being energized by the error signal so that piston 13 is moved at the required speed. At the same time, clutch 27 is disengaged, actuator 12 is idle, and the error signal is disconnected from valve 26, the piston 24 being in its extreme left-hand position. When piston 13 closes switch 23, a switch 45 is operated whereby wiper 46 engages each of its contacts in turn. This transfers the error signal to valve 26 to drive piston 24 at the required speed, the clutch 27 being engaged by the time the piston 24 has reached full speed. Piston 13 is then de-coupled from the table and the error signal is disconnected from valve 15 which is afterwards connected to source 50 for returning the piston 13 to its left-hand position wherein switch 22 closes to disconnect the valve from the source. Actuator 12 remains operative until piston 24 closes switch 30, whereupon stepping switch 55 changes the actuators in use, the actuators continuing to be brought into action alternately so that the table is driven steadily to the right at a speed determined by the control signal. In another arrangement, tachometer generators are coupled to the actuators to produce a velocity-error signal, indicating the relative speed of the pistons, which is used to prevent further stepping movement of the wiper associated with the off-going actuator until the signal is zero, whereby the on-coming actuator . is not clutched to the table until the speed of its piston equals that of the off-going actuator. In addition, the velocity-error signal is used to accelerate the movement of the on-coming piston, Fig. 3 (not shown). In this embodiment, means are provided for automatically reversing the table when the error signal from the device 31 changes sign. If the actuator 12 is driving the table to the right with piston 13 in its lefthand position, the piston 24 is automatically reversed when the error signal changes sign. At the same time, the piston 13 is transferred to its right-hand position and the functions of the switches 22, 29 and 23, 30 are changed over. Where the control signal represents the required position or acceleration of the table rather than its velocity, the tachometer 34 is replaced by a device responsive to the quantity controlled. Each clutch comprises a dovetail slot in the table within which there is a member of complementary shape coupled to the actuator and movable towards the open face of the slot for engagement therewith, Fig. 2 (not shown).

Abstract: 1330427 Coils ALLMANNA SVENSKA ELEKTRISKA AB 19 April 1971 [24 Feb 1970] 22555/71 Headings HIP and HIT A conductor 1 is threaded through a shrinkable insulating tube 5 several times to form a coil, then the tube is shrunk tightly over the coil. First the tube is threaded over a circular frame 2, through a gap formed by removable section 3, then clamped between jaws 6, 7. The end of the insulated conductor 1 is attached to the frame at P and the frame rotated by rubber rollers 4 to coil the required number of turns on the frame, which is of L-shaped cross-section with additional supports 8 attached by screws. Next the frame portion 3 and the guide supports 8 are removed and the tube slid out through the gap and the coil taken off the frame. Soft rubber, or insulation which is liquid when heated (37) may be inserted in the tube to fill air pockets and the tube shrunk progressively along its length by hot air emerging from a ring 33, so that the surplus insulation material 37 is pushed in front of the shrinking zone. If the tube is corrugated 35a it may get longer as it shrinks and cover all the coil. Alternatively several shorter tubes may be used, overlapping or separated from each other, or the tube may be radially stretched elastically and released when the coil is inside. The coil may be wound first then threaded through the tube. Silicon rubber is suitable for the tube, and the coil may be used for high currents or high voltages in, e.g. transformers and rotar windings.

Abstract: 1,182,324. Semi-conductor device matrices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 May, 1967 [19 May, 1966], No. 22690/67. Heading H1K. [Also in Division G4] A transistor T is situated at each crossing point of a predetermined pattern in a matrix comprising pluralities of input and output conductors V, H, respectively. The emitter region E is connected to the corresponding output conductor H while the base region B is connected to the input conductor V. All the collector regions of the transistors are connected in common, and may comprise the bulk of the plate in which the matrix is formed. The embodiment shows an N-type silicon plate having diffused therein P-type and N-type base and emitter regions B, E, each input conductor V also comprising diffused P-type and N-type regions P, N, isolated from the N-type bulk by a reverse biased junction. The P-type and N-type regions comprising the input conductor V are connected together by a conducting layer AB. The output conductors H, and branch conductors AE and AB connecting the conductors to each transistor, consist of aluminium vapour deposited on to a silicon oxide coating over the semi-conductor surface. A photo-resist technique is used to define the diffusion and contact apertures in the oxide coating. The N-type regions E, N are of higher conductivity than the P-type regions B, P. Transistors may be formed at each crossing point on the matrix, but the emitter regions of those not lying in the predetermined pattern are not connected to the relevant conductor, e.g. by leaving the oxide layer unbroken over these regions. If required, the base regions may be connected to the conductors H, which may lie directly over contact apertures on the base regions. In this case the emitter regions will be connected to the conductors V.

Filed: 1934-08-07
Abstract: Lubricating-oils are obtained by (1) extracting lubricating stock with sulphur dioxide alone or mixed with an organic solvent for constituents other than wax and separating the treated stock; and (2) dewaxing in presence of a mixture of sulphur dioxide and such an organic solvent.  The dewaxing may precede the extraction, or the stock may first be partially dewaxed, then extracted, and finally dewaxed thoroughly.  Solvents specified are benzol, toluene, xylene, petroleum naphtha or fractions thereof, e.g. a sulphur dioxide extract of straight run or cracked naphtha, ether, isopropyl ether, methylene chloride, ethylene dichloride. Usually, the proportion of sulphur dioxide to solvent and to stock is lower in the dewaxing than in the extracting operation.  In an example, a wax slop from crude petroleum is agitated with an equal volume of a mixture composed of 85 litres of liquid sulphur dioxide and 15 litres of benzol, the mixture settled, and the extract removed.  The treated oil is then mixed with 3 vol. of a mixture of 80 litres of benzol with 20 litres of liquid sulphur dioxide chilled, and filter-pressed at 5 DEG  C.
