Title: Improvements in or relating to the vacuum distillation of hydrogen peroxide and other easily decomposable liquids
IPC: C01B15/03
Filed: 1935-08-21
Abstract: <FORM:0457291/III/1> In apparatus for distilling liquids such as hydrogen peroxide under reduced pressure and comprising feed tanks, an evaporator, and receivers, the feed tanks and receivers are connected to the same vacuum pipe line to maintain substantially the same degree of vacuum at every point in the apparatus.  The liquid flows from feed tanks b connected to the vacuum pipe line c through a vessel e which is also provided with a connection to the pipe line c. The level of the liquid will be maintained substantially at the level of the entrance of the vacuum connection of vessel e owing to the air lock formed in this vessel.  The liquid then flows through heated tubes g to the main evaporator tubes h.  The tubes g produce a heat pump circulating effect but if the main evaporator tubes are vertical they can be dispensed with.  Liquid and vapour are separated in vessel i, the liquid passing to receivers o, and the vapour passing through condenser l to receivers m.  All these receivers are connected to the vacuum pipe line c.  In a modification the liquid is passed through a succession of evaporator tubes and separator chambers.

Abstract: 1357266 Semi-conductor devices ASSOCIATED ELECTRICAL INDUSTRIES Ltd 7 May 1973 [19 May 1972] 23627/72 Heading H1K A semi-conductor device is made by bonding a first insulating layer to the surface of a semiconductor body via a further insulating layer of low dielectric strength and then making electrical connection via said further layer between the body and a conductive layer on the first layer or by a voltage punch through technique. In the described embodiment the body is a 100 Á thick wafer of 0À8 milli-ohm. cm. N-type gemanium, the further insulating layer is formed to a thickness of 0À1 Á by evaporation of silicon in air at reduced pressure, and the first insulating layer is deposited silicon oxide 0À4 Á thick. After etching a 2 Á diameter through the centre of the oxide layer by a preferential etchant successive layers of aluminium, titanium and gold are deposited and an electrode provided on the back face of the wafer.

Title: Improvements in and relating to electrical pulse delay and regeneration means
Inventor: CHISHOLM KENNETH DUNCAN FRASER
IPC: H03K5/135
Filed: 1958-07-23
Abstract: 923,493. Transistor pulse shaping circuits. ENGLISH ELECTRIC CO. Ltd. July 17, 1959 [July 23, 1958], No. 23696/58. Class 40 (6). Fig. 1 shows a circuit which responds to each of a sequence of input pulses to regenerate the pulse and improve its shape one digit period later and supplies two output pulse signals one being the inverse of the other. Distorted input pulses, Fig. 2(a), are applied to thei nputs of diodes D1 ... D7 which constitute an AND/OR gate the output from which is applied to the base of transistor T1. Clock pulses, Fig. 2 (b), are applied via diode D8 to the base of transistor T1 so that the transistor conducts provided that clock pulses are present and input pulses are also present simultaneously at either all of the inputs to diodes D1, D2, D3 or to both of the inputs of diodes D4, D5. When transistor T1 is pulsed into conduction the circuit C1, L rings to generate pulses, Fig. 2(c), having a duration equal to the clock pulse duration. The circuit C1, L is heavily damped and the resulting oscillations are applied together with a reset signal, Fig. 2(d), to the base of the emitter follower stage T2. When a ringing pulse occurs diode D9 conducts and prevents the base of transistor T2 rising to plus 7 volts by the reset signal so that when a wide pulse, Fig. 2(e), changes by 5 volts, the base of T2, Fig. 2(f), falls to minus 4 volts and remains there until the next reset pulse occurs. Thus transistor T2 is conductive for a period determined by the width of the wide pulse. The output from emitter follower T2 is amplified by transistor amplifier stage T3 to give two pulse output signals, Fig. 2(g), (h) the levels of which are clamped by the operation of diodes D11, D12. The outputs may be fed to the input circuits of a further similar stage.

Abstract: 693,545. Resilient mountings. BARRY CORPORATION. Oct. 15,1951, No. 23953/51. Class 108 (iii). A resilient mounting comprises a rigid shell 10 having an opening 20 through which extends a stud 19 supported by, and coaxial with, a main resilient member 17, and an enclosure member for the resilient member 17 having a resilient side wall 30 and impervious to air except for a relatively small aperture 36, damping of airflow through which prevents excessive oscillation of equipment secured to the stud 19. The stiffness of the spring 17 increases with load, due to bottoming of successive coils. This results in the natural frequency of the spring remaining constant for a load varying between 25 and 75 lbs. Specification 689,884 is referred to.

Title: Improvements in the manufacture and production of carbon monoxide and hydrogen from methane
IPC: C01B3/40
Filed: 1930-08-11
Abstract: Carbon monoxide or hydrogen are produced from methane or gases containing it, such as natural gas, illuminating gas or coke oven gas, by subjecting these gases at high temperatures, 600-1,000 DEG C. preferably 800-1,000 DEG  C., to the action of the higher oxides of the heavy metals, that is, metals having a specific gravity of 4,5 or more, which oxides are not reduced by hydrogen under the conditions of working; the pressure employed may be below, above or atmospheric.  Restoration of the higher oxide after reduction is effected by treatment with air, steam, or carbon dioxide, practically pure nitrogen, hydrogen and carbon monoxide being thereby produced. Suitable metallic oxides are those of chromium, titanium, tungsten and molybdenun.  To prevent gradual disintegration of the oxides, they are mixed with substances stable to the reaction e.g. magnesium or aluminium oxide. Examples are given of the treatment of methane by titanium dioxide and a mixture of magnesium and chromic oxides, restoration of the reduced oxides being effected by treatment with air and steam respectively.

Abstract: 337,811. Lanchester, F. W. Aug. 7, 1929. Magnetic instruments; gramophone pick-ups.- An electromagnetic pick-up has a holder for the needle, or armature carrying a needle, consisting of a sleeve of rubber or similar material, which may be open or closed at its upper end, and is so formed that the needle or armature is adapted to roll in an oscillatory manner within the holder in conformity with the vibrations impressed upon it. In Fig. 9, the needle 4 is supported by two rubber blocks 17, 18 and the reaction of the record on the tip of the needle. A force in the direction of the arrow at the tip of the needle causes a rolling motion. This effect is obtained in the pick-up by the needle being loosely held by the sleeve so that in operation it bears on two edges only; or the sleeve 14c may be almond shaped, Fig. 10, to accommodate the armature 5. The rubber sleeve, Figs. 7, 8, is held in position by the spool 6, Fig. 1, mounted between the four laminated pole pieces of a magnet 1. A bar 2 of insulating material carries terminals 8, and clamping washers 8a holding leads 7a, 7b to the coil 7 and 9a, 9b to the amplifier. The pick-up may be mounted as described in Specification 321,967. When the needle serves as an armature, it may be inserted in the rubber sleeve from above or below. The needle may otherwise be connected to the armature 5, Fig. 11, by a clamping nut 15 and screw 16, the armature having a V-shaped or cylindrical slot along its length to accommodate the needle 4. According to the second Provisional Specification, the needle when serving as an armature may be of soft iron and may have its point hardened by the electrodeposition of iron; or the needle may be in two parts, an outer cylinder of soft iron and a core of hardened steel capable of renewal by simple insertion.
