Abstract: 1356325 Rolling mills P V POULSEN 27  Aug 1971 [8 Sept 1970] 40425/71 Heading B3M [Also in Division H1] In an electric coil consisting of a continuous flat strip-shaped conductor wound on a bobbin together with one or more layers of insulating material, the conductor is provided with thicker sections, as between 10 and 11, such that terminals can be formed therefrom. In the embodiment described the conductor is fed through rollers 3 with a variable gap which can be varied and selected quickly and accurately within a range of 0 to 1 mm. Variation of the gap results in locally thickened portions in the conductor. The insulation is fed from a separate storage coil or alternatively the insulating layer may be attached to the conductor. When a terminal is required the gap is increased, the strip is slit along the thicker portion thus produced and the slit portion is bent free of the strip and the gap is then reduced as required. A hammer of a special tool may be used to facilitate bending the slit portion to form the terminal. The winding machines to effect the invention are described.

Abstract: 1,099,796. Photo-electric control of photographic printing. ILFORD Ltd. Sept. 26, 1966 [Sept. 27, 1965], No.40950/65. Heading G1A. In a timer for a photographic printer of the type in which current from a photo-cell or other constant current source is integrated by a capacitor and the voltage thereacross fires an electronic relay, an initial potential is applied to the relay from a source of voltage k times the firing voltage of the relay by a potential divider comprising a fixed resistor and a variable resistor having a maximum value less than 1/(k-1) times the value of the fixed resistance. k lies between 1À0 and 2À0 and preferably between 1À05 and 1À30. With this arrangement, linear variations of the resistor to take account of film speed or subject matter cause corresponding logarithmic variations of the exposure interval. In the stand-by condition, relay A/3 is energized through R 5  and R 7  and the trigger of a cold cathode tube V 2 , Fig. 5, is connected to the junction of resistors R 1  and R 2  over a/1 and its potential is determined by the setting of the variable part of R 1  i. e. R 1B  and R 1c . Exposure is initiated by opening S1. A/3 drops out to energize the exposure lamp L through a/3 and break a/1. The capacitor Cl is charged by the current through the photo-cell V 1  until the potential across it fires the tube V 2 . A/3 then pulls in to extinguish the lamp L and return the timer to its stand-by condition. In modifications, the capacitor may be in parallel with R 2 , Fig. 2, (not shown) or in series with R 1  and R 2 , Fig. 3, (not shown). Exposure may be terminated by a shutter instead of extinguishing the lamp.

IPC: A61K9/113
Filed: 1963-10-25
Abstract: Injectable compositions containing antigenic material comprise a multiple oil/water emulsion in which the continuous phase is aqueous and the primary disperse phase is an oil phase in which an aqueous phase containing antigenic material is dispersed.  Oils may be therapeutically acceptable mineral oils, or vegetable oils such as arachis oil.  The emulsions are prepared by subjecting a mixture of a water-in-oil emulsion having antigenic material in the aqueous phase, an aqueous medium, and an oil-in-water emulsifying agent, to emulsifying conditions; e.g. ultra-sonic vibrations, or treatment in a homogeniser.  The stability of the emulsions may be improved by incorporation of agar in the aqueous component.  Examples are given for the preparation of vaccines for poliomyelitis, pertussis, tetanus, influenza, Newcastle disease, and a multiple vaccine for pertussis, tetanus, diphtheria, poliomyeltitis and measles.

Title: Floor treating machines

Filed: 1972-09-12
Abstract: 1376008 Floor cleaning machines R G DIXON & CO Ltd 7 Sept 1973 [12 Sept 1972] 42345/72 Heading A4F [Also in Divisions B7 and H2] A floor treating machine comprises a pair of independently movable manually operable control members 25 each operably connected to an individual electrical component 18 forming part of one of the two independent speed controls of a pair of driving wheels 14, and synchronized movement of the control members 25 adjusts the wheel speeds equally whereas differential movement provides a steering effect. In the illustrated embodiment each component 18 is a potentiometer controlling the speed of a motor 15 driving a wheel 14, each potentiometer 18 being adjustable by rotation of a pinion 23 Fig. 1 (not shown), by a gear sector (23a) carried by a control member 25. A transverse member 22 connects the members 25 to a handle 19, which when fitted about a pivot 21 without horizontal swivelling varies the two motor speeds identically, but which when swivelled horizontally adjusts the potentiometers 18, and thereby the motor speeds, differentially to produce a steering effect. On release of the handle 19 it is returned by springs 24 to an off position in which the motors are braked electro-magnetically, and from which pulling of the handle 19 actuates motor reversing switches, the motors then running at a constant speed controlled by fixed resistors 35. The potentiometers 18 control the motor currents directly, but in a modification potentiometers 18a, Fig. 4, having rectilinearly movable sliders 42 control the motor currents via amplifying circuits. Each slider 42 controls reversing switches FR, of which either the contacts F or the contacts R are engaged for forward or reverse movement when the slider engages a respective half of the potentiometer. Thus in either forward or reverse running a signal from a slider 42 is applied to a motor armature 44 via an amplifier 47, whilst a constant voltage is applied to the motor field winding 43. The motor speed is maintained constant for any setting of the slider 42 by applying to amplifiers 47, 48 a signal from an amplifier 55 responsive to variation in the back EMF generated in the armature 44, the amplifier 47 being effective to increase the motor current when the motor speed is low, and the amplifier 48 applying dynamic braking when the motor speed is too high.
