Title: Improvements in electric pulse modulation systems of communication
IPC: H04J3/04
Filed: 1944-06-02
Abstract: 592,412. Multiplex wireless signalling; pulse modulation. STANDARD TELE. PHONES & CABLES, Ltd. June 2, 1944, No. 10680. Convention date, Feb. 6,1943. [Class 40 (v)] A receiving arrangement for selecting a particular one of a plurality of signal modulated electric pulse trains, the repetition frequencies of which trains differ slightly from one another. Comprises means for blocking the receiver against the undesired pulses and means for blocking the receiver also against the desired pulses for those periods during which the desired and undesired pulses overlap. Figs. 1 and 2 show an arrangement in which 10 is a source of pulses a, Fig. 2 (I), and 12 is a source of pulses b, Fig. 2 (II), the two-pulse frequencies being slightly different. The pulses a and bare transmitted on a common channel 14 which may be wired or a common carrier wave, and received by receivers 16, 16<1> which both receive both trains of pulses. Considering 16, the input will be as in Fig. 2 (III) showing at intervals varying degrees of overlapping of the a and b pulses. A blocking unit 20 producing pulses as in Fig. 2 (IV) blocks the first receiver 18 except during the a pulses, thus giving an output as in Fig. 2 (V) in which the b pulses are removed except where they overlap the a pulses to produce peaks. The peaks are taken off in a clipper 28 and inverted in a shaper 30 to be applied to a second receiver 26 to eliminate those parts of the a pulses which are overlapped, thus giving an output as in Fig. 2 (VI). The pulses are differentiated at 32 and demodulated at 36, and finally passed through a low-frequency rejection circuit 38 to remove the low beat note due to the periodic absence of pulses and clipped pulses in the waveform, Fig. 2 (VI). The output will be free from interference by b pulses. The receiver 16<1> operates in a similar way to eliminate the effect of a pulses. Any number of channels may be similarly treated. In a modification, Fig. 3 (not shown), the interfering pulses are eliminated at the carrier frequency stage. In this case, the second blocking pulse is made wide enough to cover the complete series of consecutive overlapped pulses and eliminate them to leave wider gaps in the resulting pulse train. The invention may be used to eliminate a jamming pulse which is not exactly synchronized with the desired pulse signal.

Title: Positive cross feed stop assembly attachment for turning lathes
IPC: B23Q16/04
Filed: 1943-07-05
Abstract: 569,883. Turning. JACOBS, J. H. July 5, 1943, No. 10868. Convention date, May 13, 1942. [Class 83 (iii)] In a lathe having a slide 10 fed by a handoperated screw 18, a number of discs 24 are capable of being secured to the screw individually at different angular positions so that a dog 37 on any selected one of the discs may be brought into contact with a stationary stop 33 in order to limit the feed positively. The end disc 24<1> is keyed at 27 to an extension 21 of the screw so that its dog 37 will provide a zero setting for the screw when brought into contact with the stop 35 having a hooked end 36, this setting corresponding with the zero graduation of a dial attached to the handle end of the screw. Spacing washers 25 between the adjustable discs 24 are also keyed to the screw to allow any disc to be adjusted without influencing the others when the clamping nut 29 is released. One stop 33 is provided for each of the discs 24 and has a square end 34, the stops being pivoted on a fixed pin 32 so that their ends 34, 36 are normally maintained by gravity clear of the dogs 37. To set any stop in position to engage its appropriate dog 37 and thus stop the feed at a point predetermined by the adjustment of the disc 24, the stop is tilted about its pivot 32 by a rod 38 having a handle 38b co-operating with a notched plate 39 at the front of the lathe and a hooked end 38a for engagement with the required dog at the rear of the lathe. The hooked end 36 of the end stop 35 provides for engagement with its dog 37 when the screw 18 is rotated in either direction, and the apparatus may be built into a lathe or may form an attachment to an existing lathe.

Title: Process for refining crude chromium alloys
IPC: C21C7/00
Filed: 1923-04-24
Abstract: 223,617. Borchers, W., and Stimson, R. W. April 24, 1923. Alloys; roasting.-Alloys containing iron and one or more of the metals chromium, molybdenum, and uranium in any proportions, with or without other metals, are refined by means of an agent consisting of a highly oxidized artificial solid solution containing one or more of the above metals. The agent, which is basic and has a melting point below 1600‹ C., may be made by roasting under freely oxidizing conditions an intimate mixture containing minerals or compounds of one or more of the metals and one or more basic oxides such as lime or magnesia. The basic oxide is used in such proportion as not only to form chromates &c., but also to give the product a basic character, and preferably also in sufficient excess to ensure that acid oxides formed during the refining operation will be retained in the slag without requiring the presence of further flux. The materials to be roasted are dried and coarsely crushed, and are preferably bound by means of a solution of an alkali or alkaline earth carbonate or hydrate. Burnt lime may be slaked with a solution of the binding-agent to a thin paste into which powdered chromite may be kneaded, the pasty mass being dried, coarsely crushed, and roasted. The refining-agent may be used by being fed on to the surface of the molten crude alloy, fluxes being added towards the end of the reaction if required. Any further metal or metals required in the alloy may be added before, during, or after the refining-operation.

Title: Methods of making moulded light weight heat-insulating products
IPC: C04B28/18
Filed: 1933-04-13
Abstract: Light weight, heat insulating bodies are made by finely pulverizing and mixing siliceous and calcareous materials, adding water in a proportion exceeding 100 per cent of the solid ingredients to form a slurry, (the pulverization and mixing having been effected to such a degree that no sedimentation occurs in the slurry), moulding, hardening (preferably by steam) and drying. The slurry may be thickened before moulding by allowing it to stand, by stirring or by heating e.g. by exposure to steam to form a thixotropic stiff gel. Calcareous materials include hydraulic, quick or slaked lime, and natural, Portland or Roman cement. Siliceous materials include sand, clay, diatomaceous earth, shale, marl, moler, granite, sea mud, slag, artificial or natural pozzuolanas including calcined shales, cinders and the like.  If such siliceous materials have a naturally porous structure e.g. diatomaceous earth, they must be pulverized until this structure is destroyed.

A region of P-type is formed in an N-type semi-conductor body by bombarding with a beam of electrons with energies in the range 30 to 200 KeV to a total dosage of between 10<SP>16</SP> and 10<SP>22</SP> electrons/cm.<SP>2</SP>. An intermittent beam may be used to avoid excessive rise in temperature of the bombarded material and resultant destruction of the Frenkel acceptor defects produced in the process. N-type silicon wafers 20 are treated in the apparatus shown in the following manner. A wafer is ejected from magazine 34 by a finger 39 operated by motordriven bevel gears 38 via cam 38, and moved forward into the electron beam 14 on endless conveyer belt 31. Motor 32 then stops for a predetermined period while the wafer is bombarded. The operation is then repeated to discharge the treated PN junction wafer into bin 40 and bring forward another wafer into the beam. To form PNP wafers suitable for transistors each wafer when in the beam is flipped over after a predetermined time and subjected to further bombardment before being discharged into the bin. The electron gun includes an assembly consisting of anode 3, control cylinder 2 and cathode 1, an adjustable diaphragm 11, beam deflector coils 9, 17, electromagnetic lens 16, and an optical system for observing the bombarded surface. Beam power is controlled by adjusting the potential of the control cylinder. Converted regions of various configurations may be produced by movement of the beam during bombardment.
