Filed: 1943-11-19
Abstract: 571,188. Moulding-machines. COLEMAN, C. W. Nov. 19, 1943, No. 19391. [Class 83 (i)] Patterns.-A moulding-machine having concentric plungers of which the larger G<1> is for jarring and the smaller G for drawing, is provided with a pattern plate D which forms the top of a box F and is perforated at S' so that air can be forced through said plate to assist in drawing the mould. Sand is supplied by a conveyer (not shown) to a box E having at an' intermediate point two flaps h<3>, Fig. 2, normally held in a horizontal position by springs Z. The box E is then swung about its pivot V to bring it into the position shown and by releasing air from the bottom of a cylinder R, a weight H is lowered onto the sand, pushing it into the bottom part of the box E and into the flask K, Fig. 1. Air pressure is then.admitted to the floating-anvil cylinder X to reciprocate the jarring plunger G\ columns A, B, pattern plate D, &c., and compact the sand. The weight is then raised by admitting air pressure to the bottom of the cylinder R and the box E is swung out of the way. Air pressure is then admitted to the box F and through the drawing plunger G into its cylinder which is the plunger G<1>. This causes the plunger G, plate G<2>, Fig. 2, and fingers G<3> to lift the flask K and mould from the pattern S. The flaps h<3> are held in either extreme position by the springs, but when the weight H is raised it engages lugs h<1>, Fig. 1, to bring the flaps into horizontal position again, ready for another charge of sand. Electric heaters T enable hot air to be blown through the holes S<1>. A duplex machine may be arranged in the same way.

Title: Improvements in cam-actuated electric contact breakers
IPC: F02P7/063
Filed: 1946-07-01
Abstract: 614,035. Cams. HITCHCOCK, S. I. July 1, 1946, No. 19667. [Class 80 (iii)] [Also in Group XXXVII] A contact-breaker with a variable contact gap, intended primarily for use in electric motors of the type described in Specifications 547,668 and 564,865, [both in Group XXXV], comprises an insulating base-plate 7 carrying the fixed contacts 6 which co-operate with moving contacts 5 on rocker arms 4, which are actuated by a longitudinally tapered cam 1 having four lobes 3. On turning the knob 8, a threaded spindle 18 moves in or out, so causing angular movement of a cranked fork 12 about the fixed pivot 13. The ends of the fork engage a collar 10 attached to the cam 1 so that the movement of the fork moves the cam along a squared shaft 2, so altering the effective lift of the cam on the heels of the rocker arms 4 and hence the contact gap. In a modification, Fig. 5, a cam with a recess 21 accommodating radiallymovable lobes 20 is fixed to the squared shaft, but the collar 10 is movable axially to force inclined parts 24 thereon into or out of the lobes 20 thus altering their radial position and hence the lift given to the rocker heels. In both cases the plate 7 may be turned relative to the shaft by a lateral movement of the knob 8, to alter the position of the contacts with respect to the cam.

Patent GB-1012049-A (GB)
Title: Semiconductive devices
IPC: H01L29/00
Filed: 1962-05-24
Abstract: 1,012,049. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. May 24, 1962 [May 26, 1961], No. 19960/62. Headings H1K and H1W. A semi-conductor diode used for shortcircuiting overload voltages in the reactancecoupled, paired transmission lines of a microwave system has a main body of high resistivity or intrinsic material on which are placed the two terminals. At least one of the terminals is capable of double injection, and consists of a low resistance electrode effectively in common with both or all the regions of an associated terminal zone comprising at least one N-type region and at least one P-type region, the region being of such thickness and so disposed that the application of a signal of either polarity between the electrode and the other terminal will cause the injection of change carriers from the zone into the main body of the diode. One or more of these diodes may be mounted in parallel between conductive posts extending from opposite sides of the transmission line. In the silicon diode shown in Fig. 1 each of the electrodes 22, 23 makes ohmic contact to both the P-type regions and N-type regions of their respective terminal zones. The impedance of the device is inversely proportional to the square of the number of change carriers present in the intrinsic body and decreases rapidly as the applied voltage is increased. Carrier withdrawal during polarity reversals is kept down by making the device so that the adjacent N-type and P-type region present small cross-sectional areas to the main body region. When the applied signal is small the diode behaves as a high quality capacitor of low value whose susceptance can be tuned out to minimize transmission losses. However when the applied signal is large the capacitance (and conductance) increases and the resulting relatively high susceptance reflects the signal back down the transmission line. A device may be made similar to that shown in Fig. 1 but in which the P- and N-type zones of each terminal region instead of being adjacent are present as dots or stripes separated by small areas of high resistivity material. One end of a further device is shown in Fig. 3. Here the terminal zone consists of an N-type layer 52 into which extend the heavily doped portions 53 of the adjacent P-type layer 51. A somewhat similar device is described with reference to Fig. 2 (not shown). In this case the terminal zone has contiguous plane layers of N-type and P+ material, the P+ layer being adjacent the electrode. The second electrodes of the embodiments of Figs. 2 and 3 may be identical to their respective first electrodes described or they may differ from these by the mere interchange of the conductivity type of the layers. In use carriers are injected from the P-type layer or N-type layer depending on the polarity of the signal applied to the terminal. The Specification contains a brief description of the manufacture of devices of the type shown in Fig. 1. It is stated that the diodes may also be made from germanium and A<SP>III</SP>B<SP>V</SP> compound semiconductors.

Abstract: 773,019. Fluid-actuated valves. SPECIALTIES DEVELOPMENT CORPORATION. July 11, 1955 [Aug. 11, 1954], No. 20012/55. Class 135. A fluid pressure operated valve, operated after a time delay from the start of building up the pressure, comprises a body having an inlet chamber 21, an outlet chamber 22 adjacent a horizontal cylinder 25 with a piston 34 for unseating a valve 31 controlling communication through a vertical partition between the chambers, a section 26 beneath the partition for securing the valve to a container 10 for e.g. carbon dioxide, and formed with a passage, part of which is shown at 36, leading from the inlet to a metering tube inserted into the container and a second passage 29 extending from the cylinder 25 to the container via the section 26. Carbon dioxide supplied to the inlet chamber passes at 36 through the metering tube into the container. After a certain time the pressure in the container acts via passage 29 and moves the piston 34 to the left to open the valve against the spring 32 so that carbon dioxide then passes through the outlet chamber. To pass the carbon dioxide to the outlet earlier a stem 54 may be screwed down to open a pilot valve 49 whereby inlet pressure acts on the piston via passage 30 and check valve 55 to open the valve 31. A filter is provided in the passages 30,36.

Abstract: 855,495. Casting-machines. GOLDHAMER, W. M. June 12, 1959, No. 20187/59. Class 83 (1). A die-casting machine has a separate metal cooling member 24, 25 secured to each die member 6, 7 at least one of said cooling members being movable into engagement with or away from the other cooling member during movement of the die member to which it is attached, a passageway 27a, between the engaged metal cooling members connected to a vacuum duct 28 or exhaust and the die cavity 16, and means for cooling the said cooling members to solidify metal in said passageway before the metal solidifies in the die cavity. The cooling members have chill blocks 46, 47, Figs. 5, 6, with corrugated surfaces which define the tortuous passageway 27a and coolant channels C. The member 25 includes an ejector plunger 57, Fig. 6, which is actuated by striking the machine frame as the dies open, to engage the solidified metal in the passageway and eject it and the attached casting. A baffle 52 and filter 54 prevent particles of metal entering the vacuum system. The cooling members are insulated from the dies by air pockets 41. Solenoid valve 31 in the vacuum system is actuated by a switch 34 on die closing to apply vacuum which is restricted by an orifice 30. A solenoid valve 35 is actuated by timer T to apply full vacuum. A passageway 39<1> opposite the passageway 27a is connected to pressure recording and indicating apparatus 29. The injection plunger 58 is longitudinally slotted and is capable of limited rotation about its longitudinal axis by a cylinder 80, Figs. 10, 11, controlled by a valve 82 actuated by the timer T. The arrangement is such that after die closing and with the plunger retracted and in the position shown in Fig. 10, the application of the partial vacuum to the die sucks up a charge of molten metal from the container 21 into the injection chamber. After a timed delay the cylinder 80 turns the injection plunger to the position shown in Fig. 11, whereat the slot 61 connects the metal feed pipe 20 to atmosphere to allow the metal in the pipe to return to the vessel 21, the solenoid valve 35 is actuated to apply full vacuum and then the cylinder 67 forces the injection plunger forward.
