Title: Improvements in or relating to the conversion of straight chain paraffin hydrocarbons into isoparaffin hydrocarbons of high anti-knock value
IPC: C07C5/27
Filed: 1940-06-08
Abstract: 547,457. Isomerizing hydrocarbons. TEXACO DEVELOPMENT CORPORATION. June 8, 1940, Nos. 10049 and 10050. Convention dates, June 30, 1939, and June 30, 1940. Drawings to Specification. [Class 2 (iii)] Straight chain paraffin hydrocarbons of gasoline boiling point range are isomerized into isoparaffin hydrocarbons by subjecting such hydrocarbons substantially free from olefin and aromatic hydrocarbons to a treatment with an isomerization catalyst under isomerizing conditions characterized in that an amount of isobutane which is substantially in excess of the paraffin hydrocarbons undergoing conversion is added to the reaction mixture. It is stated that as a result of the addition of isobutane the catalyst does not become involved in secondary side reactions. Catalysts mentioned include the preferred aluminium halides in the presence of hydrogen halide promoters together with other halide catalysts such as the halides of zinc, iron, zirconium, tin, barium, columbium, tantalum and boron. The catalyst may be used in lump or granular form or in the case of aluminium bromide at temperatures above 208‹F., in liquid form, or supported on carriers such as synthetic and natural clays, silicon gel, pumice, brick, coke, activated alumina and activated carbon. The process may be carried out by the batch method or as a continuous process, and either in the liquid or gaseous phase. Mixtures of isobutane and normal butane may be recycled to suppress the deterioration of the catalyst. Examples are given of suitable reaction conditions. Specifications 515,531 and 535,398, [Group III], are referred to.

Title: Improvements in or relating to apparatus for use in joining together lengths of photographic or cinematograph film
IPC: G03D15/04
Filed: 1922-04-08
Abstract: 178,128. Pollak, J. E., (Correxm³vek Filmipari Gepgyar C. Lazzlo). April 8, 1922. Affixing by adhesives.-Two ends of kinematograph film to be joined are held in clamps, one of which is fixed and the other movable; after the ends of the film have been trimmed and scraped the movable clamp is moved in guiding devices which bring the two ends together in appropriate relation. The fixed clamp comprises a spring jaw 3 pivoted to a fixed jaw 8 and adapted to be locked down thereon by a catch operated by a handle 10. The jaw 8 is provided with pins 13 to enter the openings at the side of the film and projects beyond the jaw 3 so as to form a backing on which the end of the film rests for scraping and fixing. The jaws 14, 15 of the movable clamp are similar to those of the fixed clamp, but the upper jaw projects instead of the lower and between them is arranged a sliding plate 16. The jaw 15 is connected by spring 29, 30 to a block 20 carried on a sliding rod 22, and is also provided with trunnions 27 working in U-shaped bearings 28 on the block 20. When the ends of the film have been trimmed and the left hand end has been scraped and coated with adhesive the movable clamp is moved to the left, when a piece 33 attached to the plate 16 strikes against a stop 34, thus arresting the plate 16 and exposing the end of the film. A pin on the jaw 15 then rides over a cam, raising the clamp against the action of the springs 29, 30 and then releasing it so that the end of the jaw 14 with the film is brought down on to the film on the jaw 8. The cutting and scraping devices may consist of blades 36, Fig. 2, and a scraper 37 on a transverselymoving carriage 35 attached to links 40, 41 provided with slots 43, 45, or the cutter blades may be mounted on a rocking arm 49, Fig. 5, which also carries guides 52, 53 on which slides a block 55 carrying a scraper 59. The scraper 59 ronsists of a spring steel blade, of such length as to be bent when in action and to straighten suddenly after passing the edge 61 of the frame of the machine, thus driving away the scrapings. A lamp-housing 47 covered with a glass plate 46 to assist in examining the film for defects is also provided.

Title: Improvements in or relating to variable electric resistances and potentiometers
Inventor: BARNES HAROLD ERNEST
IPC: H01C10/40
Filed: 1952-04-23
Abstract: 722,284. Variable resistors. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 23, 1953 [April 23, 1952], No. 10170/52. Class 37. In a variable resistor of the type in which a sliding contact 17 is moved relatively to an elongated resistance element 8 by rotation of a helically grooved operating rod 6 of insulating material, the contact comprises a resilient roughly V-shaped member 17 (see Fig. 4) having one end 19 bent over to form a contacting surface with the resistance element, the other end 21 being narrower and having at its end a semi-circular section 22 cut at an angle to the operating rod axis to ensure accurate following of the groove. The portion 21 just fits within a U-shaped metal member 5 extending along the operating rod and acting as a guide to the contact member. A broader horizontal section 20 bears on the edges of the guide to provide a good contact between the frame and the sliding contact. If the operating rod' is turned excessively the contact rides out of the groove and remains stationary. The ends of the resistor are surrounded by metal clamps 10, 11 and the ends of the former fit into recesses in the ends of the case which may be of metal or of moulded material.

IPC: G01G23/365
Filed: 1968-03-02
Abstract: 1276831 Servosystems RESPONSE Ltd 2 June 1969 [2 March 1968] 10263/68 Heading G1N In a null-seeking servosystem e.g. for use in a weighing machine, a virtual balance is obtained with the servomotor M oscillating about the true balance point. As shown, a first voltage is derived across a potentiometer VR1, whose slider S1 is maintained at a constant voltage and is driven by an input signal, e.g. representative of a weight being measured, and a second voltage is derived across a potentiometer VR2, the resultant error signal being applied to a transistor VT1, a single sided output, high gain amplifier and the servomotor M which adjusts the slider S2 towards balancing the voltages. The servomotor may also drive an indicator. High resolution of the comparison circuit is obtained by using high resolution potentiometers e.g. plastic film and slide wire potentiometers. Although the servomotor oscillator about the true balance point, the slider S2 of the potentiometer VR2 merely trembles but is sufficient to unbalance the system and maintain the motor in oscillation. A potentiometer VR3 is used to set the balance point of the voltages and the null point of the servomotor.

Title: New or improved means for controlling electrical amplifying circuits employing thermionic valves and the like
IPC: H03H7/24
Filed: 1930-04-01
Abstract: 352,021. Reproducing music. PEARSON, L. H., 54, Long Row, Nottingham. April 1, 1930, No. 10306. [Class 40 (iv).] Relates to means for varying the voltage fed from a number of gramophone pick-ups to an amplifying valve so that one transmission can be " faded " into another, whilst the effective impedance across the valve input is maintained constant. As shown in Fig. 1, the total impedance across the contact points 4 remains uniform as the points are moved downwards, first to change the input from the pick-up PU, to the amplifier A from a maximum to zero, and then to bring in the pick-up PU2 from minimum to maximum strength. The intermediate resistance-link 3 may be suitably loaded to simulate the shunt effect of the pick-ups across the upper and lower resistances 1, 2. In Fig. 2, the two pick-ups have a common lead 5, the balancing resistance 8 being inserted as shown. In any position of the contact 10, the total impedance across the primary winding of the transformer T remains constant, because the part of the resistance 8 in circuit increases as the resistances 6, 7 are progressively cut out. The voltage input from the pick-up PU, decreases as the contact 10 is moved downwards. In Fig. 3 the control and balancing resistances 18, 18a are embodied in a rotary switch 14 operated through bevel-gearing 19 . . 22. If the contact 15 is moved to the left of the zero point 0, the input voltage from the pick-up PU2 increases, whilst movement to the right gradually brings the pick-up PU1 into circuit. In a modified switching arrangement the contact studs are arranged in four equal segments ot a circle and are cross-connected by a rotary slider-arm. Specification 298,275, [Class 40 (iv), Telephones &c.], is referred to.

Title: Improvements in or relating to disk harrows
IPC: A01B21/08
Filed: 1950-04-26
Abstract: 716,482. Disc-harrows. FERGUSON, Inc., H. April 26, 1950 [April 26, 1949], No. 10339/50. Class 6 (1) A disc-harrow comprises a frame 10 upon which a pair of disc-gangs 11 are pivoted intermediately of their ends so as to be angled in a horizontal plane, means for angling the gangs simultaneously being connected to the inner gangends, and each gang being also capable of limited vertical movement by means of a rod 41 pivoted to the frame 10 at one end and having a sliding connection 42 with the gang at the other, the arrangement of pivots being such that a spring 44 encircling the rod urges the gangs downwardly in all positions of angular adjustment with a force which increases progressively with the angling. The frame is provided with a triangulated bracket structure 63, 66, for attachment to power-operated tractor draught-links and carries further brackets 25 at its ends supporting vertical spindles 20 mounted at their lower ends 19 in bearings 18 on the shafts 12 carrying the discs 13. The bearings 18 and the inner-end bearings 17 are secured by brackets 16 to a bracing beam 14 on each gang. Each inner-end bearing 17 is further connected by a link 49 to an arm 50 depending from a tube 51 rotatable by the motion of a threaded trunnion 57 along a crank 55, the trunnion being carried by an arm 54 welded to the sleeve 51, so that rotation of the crank angles the gangs simultaneously. The connection 18, 19 is loose enough to permit pivotal movement of the gang thereabout in a vertical plane, this being resisted by a spring 44 encircling a rod 41 and abutting between an adjustable collar 47 on the rod and a bracket 42 on the beam 14. The rod is carried by a member 40 loosely pivoted on a bolt 38 carried by the frame 10, the adjacent portion of the beam 14 being loosely attached by links 32, 34 to a further bolt 31 vertically above the bearing 18 but spaced from the bolt 38. This spacing of the pivots 31, 38 causes the distance 38-42 to decrease with increasing angling of the gangs thus increasing the downward force of the spring 44 and counteracting the increased soil resistance. Specification 470,069 is referred to.
