Patent GB-481380-A (GB)
Title: Improvements in or relating to the production of machine-set type-composition
IPC: B41B25/00
Filed: 1936-11-25
Abstract: 481,380. Type-making machines. WIGG, W., and MONOTYPE CORPORATION, Ltd. Nov. 25, 1936, No. 32260. [Class 100 (iii)] Strip-perforating machines; justifying type; keyboards.-In order to produce small size and close-set composition in machines of the kind described in Specification 17199/08, [Class 100], the record-strip is prepared without signals for the casting of separate justifying-spaces, and a signal representing the justification-fraction is associated with that representing the first character of each word. The justificationfraction thus serves as an interword space, and replaces, the separate justifying-spaces normally used. The justifying - space key, which normally actuates the transfer-punch S and also one or more additional punches I, is arranged to operate, when desired, the transfer-punch only. For this purpose, the space - key has three adjustable lugs, which are adapted to actuate three key - bars of the permutation system. For ordinary composition, two of these lugs are in operative position, and for small or close-set composition, these are turned out of action, and the third lug is adjusted so as to be in position to actuate a key-bar which controls the transfer-punch only. The bar A of the punch carries a pivoted latch A<5> having a lug A<6>, which normally engages under a bail J, by which the units-counting mechanism and the paperfeed are operated. For close-set composition, the latch is moved clear of the bail, so that, when the space-key is depressed, the counting- mechanism and the paper-feed are not actuated. Depression of the next character-key therefore forms a character-signal alongside the transfer-signal. Specification 8633 /99, [Class 100], also is referred to.

Title: Process for the manufacture of ethylene diamine hydrochloride
IPC: C07C209/08
Filed: 1953-11-25
Abstract: Ethylene diamine hydrochloride is produced by the reaction of ethylene chloride with an excess of ammonia at a raised temperature under pressure in a continuous process wherein there are caused to pass continuously through a reaction tower under pressure an aqueous solution of ammonia in an upward direction, and ethylene chloride in a downward direction, and the reaction liquid is continuously withdrawn from the upper part of the tower.  The ammonia may be introduced into the reaction tower in the form of gaseous ammonia, water being added separately, or as an aqueous solution of ammonia. The preferred temperature is 50-200 DEG  C.  Preferably the ethylene chloride is introduced in finely subdivided form and filling bodies or like means are provided in the tower to prevent the ethylene chloride descending too rapidly.  The reaction liquid is freed from ammonia by releasing the pressure and boiling, and the ammonia is returned to the reaction tower under pressure.  A detailed example is given.

Title: Improvements in artificial legs
IPC: A61F2/60
Filed: 1922-12-01
Abstract: 203,591. Danin, L., (Danin, L.). Dec. 1, 1922. Limbs, artificial. -The braking device of an artificial leg is brought into action by pressure upon the toe or heel and consists of a band a connected to the lower 'portion of the leg at a point b and to the upper portion at f and passing over rollers c, d<1>, d, g, g' and g<2>. The brakes h, k are normally pressed by springs against the band a but are released bv tension on cords m, n attached to the toe and heel at p, o. When the foot is raised from the ground, springs in the foot cause tightening of the cords m, n thereby releasing the brakes and allowing the leg to be bent. Pressure on the toe or heel slackens one of the cords m, n as shown in Fig. 2 and allows the corresponding brake to act upon the band a, thus preventing further bending of the leg. The leg may however be straightened when the brakes are in action. The guide rollers are situated at points corresponding to the points of origin and attachment of the muscle system in the normal leg.

Title: Semiconductor circuit arrangement
IPC: H01L45/02
Filed: 1969-07-01
Abstract: 1,274,310. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 1 July, 1969 [15 July, 1968], No. 33047/69. Heading H1K. A space charge wave is amplified in a device consisting of a body of many-valley semiconductor material provided with a pair of electrodes between which the ratio of current density to ionized impurity concentration varies with distance in such a way that under applied voltages above a threshold level a high uniform field region is formed the length of which is variable by changing the applied voltage. The field in this region is such that the carriers exhibit negative differential mobility so that space charge perturbations introduced into it by a signal source are amplified. The variation in J/N which is preferably step-like is achieved by changes in cross-section or effective crosssection of the current path, e.g. by using contacts smaller in area than the body cross-section, and/or by doping. In the embodiments the arrangement is such that J/N falls suddenly at a point spaced from the cathode and there the uniform field region starts. In one device the input signal is applied between the cathode and a point on the side of the body in the high field region and the output taken between the anode and a point spaced #/2 therefrom. In another device both the anode and cathode, mounted on end faces of the body, are split into segments connected in parallel and parallel wired input and output electrodes disposed between the segments in recesses #/2 deep. In a further device with planar end faces the input and output electrodes are disposed between parallel pairs of strip cathodes and anodes respectively, or centrally of annular electrodes. In this case the wave front is curved and the geometry such that the output and anode electrodes are #/2 apart. In a modification of this, with input and output fed via centre-tapped transformers, the input is applied and output derived from pairs of electrodes mounted side by side to give an inclined wave front which again results in the output electrodes being #/2 apart.

Abstract: 870,748. Hydro-pneumatic suspension units. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL PRAHA. Sept. 30, 1959 [Sept. 30, 1958], No. 33183/59. Classes 108(2) and 108(3). A self-levelling hydro-pneumatic suspension unit of the type with a main piston, cylinder and resilient gas chamber is characterized by having height regulating means comprising a regulating member with a piston, 12, which pumps liquid from a storage container to the working cylinder when struck by a transverse extension of the main piston rod, 3, to increase the height and a regulating groove or series of holes which allow flow of liquid back into the storage container to reduce the height. In the described embodiment a working cylinder 1 is closed by a storage container 2 through which passes a hollow piston rod 3 with a piston 6 at one end containing valves for shock absorbing and with an enlarged upper end forming, with a closing member 8, a chamber 7 in which is a resilient container 9 for air or other gas acting as a spring. The regulating member comprises a piston 12 held in its upper position in a bore in the storage container 2 by a spring 13. The bore has a hole 15 to the storage container for the entry of liquid and a non-return valve 16 for oil to enter the working cylinder 1. In operation as the suspension responds to vehicle movements if the vehicle height is too low the transverse extension of the piston rod 3 will contact the top of the piston 12 and push it down closing off the hole 15 and pumping oil into the working cylinder 1 so raising the vehicle. When the vehicle is too high a regulating groove 19 (or series of holes) at the lower end of the piston rod 3 will enter the storage container allowing oil flow thereto from the working cylinder so reducing the height. A resilient mounting 11 may be used to attach the unit at its upper end to a vehicle. A spiral spring may be added within the working cylinder to prevent the piston 6 from sinking to its bottom position as a result of oil leakage when the vehicle is out of service. Specification 849,342 is referred to.

Abstract: 800,810. Vehicle power take-off mechanisms. BROWN TRACTORS (ENGINEERING), Ltd., D. Feb. 17, 1956 [Nov. 17, 1954], No. 33242/54. Class 79(2) [Also in Groups XXIV and XXXIV] In a vehicle power take-off device in which drive is transmitted from the vehicle engine through an input shaft d, an axiallyengageable friction clutch and a coaxial second shaft f to a splined output shaft (not shown) independently of the main transmission clutch, disengagement of the clutch causes automatic application of a friction brake to the second shaft, axial movement of a rotatable part o of the brake bringing the shaft f to rest. As shown a sleeve a mounted in bearings b in a casing c is driven by the shaft d from the engine (not shown). The sleeve a is connected to the shaft f by the clutch comprising an annular toothed member a<SP>1</SP>, plates a<SP>3</SP>, e having teeth meshing with the member a<SP>1</SP> and a member e<SP>2</SP> respectively, the member e<SP>2</SP> having a splined connection f to the shaft f and a nut n urging the member e<SP>2</SP> against a shoulder m on the shaft f. Slidable on the shaft f is a pressure plate g connected to the member e<SP>2</SP> by rods h<SP>1</SP> and springs h whereby the clutch is engaged. The clutch is disengaged by movement of a yoke i connected by pins i<SP>1</SP> to a collar j mounted by a bearing j<SP>1</SP> on a sleeve extension g<SP>1</SP> of the pressure plate g, movement of the yoke i causing axial movement of the plate g to permit disconnection between the plates a<SP>3</SP>, e. Such movement causes compression of the springs h which axially moves the member e<SP>2</SP> and shaft f whereby the rotatable brake part o formed as a flat disc on the shaft f engages a disc p of sintered bronze carried by a cover plate g on the casing c to brake the shaft f on clutch disengagement. The shaft f is connected by spur gearing k to the splined output shaft. The discs o, p may be modified by (1) causing the disc o to bear directly on the cover plate, (2) by replacement by a conical type axially engageable brake. The clutch may be of the conical type.
