[Class 97 (i).] An apertured shutter plate is reciprocated by a crank disc linked to it, and the link carries one or more feed claws ; the apparatus may be capable of use both as a camera and projector, and may comprise a removable slide behind the gate aperture, a film-controlled bolt for preventing operation of the shutter, and a film-steadying arm. As shown, an apertured shutter k is provided with a flange k<1> connected by a link l<2> to a pin l on a flywheel l<1> forming a crank disc, and the link carries a feed tooth r. The shutter reciprocates in a folded guide j, and the film passes from the holder f down the back of the guide to a holder f<1>. Spring fingers j<2> and a supporting surface, not shown, hold the film to the guide. The film is steadied between feed movements by a spring arm s normally bearing against it, and flexed during feed movements by a pin s<3> on the crank disc l<1>. The bent end t<1> of a bolt t is pulled against the back of the film by a spring, and, when the film runs out, passes through a slot in the guide to enter a slot in the shutter and prevent its movement. The apparatus comprises an objective e, a condenser v, and a removable draw tube u<1> carrying an electric lamp u, reflector u<2>, and finger grip surface u<4> ; connection between the lamp and a battery &c. is made by means of a plug u<5>. A slide w carried by grooves w<1> prevents reflection to the film by the condenser when the apparatus is used as a camera.

Title: Aromatization of powdered coffee products
IPC: A23F5/48
Filed: 1962-03-22
Abstract: Powdered coffee products, e.g. extracts, are aromatized by admixture with low-boiling coffee volatiles and an oily carrier therefor. Roasted coffee is stripped with hot gas or vapour, e.g. steam, and at least one high-boiling fraction is partially condensed from the resultant vapours, before a last, low-boiling fraction, is condensed e.g. at 0 to 15 DEG C., which is from 4 to 40%, preferably 5 to 20%, by weight, of the total condensate, which itself is 3 to 50% preferably 5 to 20%, of the original roasted coffee weight.  A mixture of this last condensate and the oily carrier, e.g. coffee oil, may be added as such to the coffee product or may be separated into an aqueous phase and an oily phase of which only the oil is added; alternatively the condensate and carrier may be added separately.  Preferred additions are 0.1 to 5% condensate, and 0.2 to 1% coffee oil, by weight of the coffee product.  The liquid or liquids are sprayed against the inside of a falling annular curtain of the powdered product in an oxygen-free enclosed space, a device for the purpose being described and the aromatized product is immediately hermetically sealed in packages under an oxygen-free atmosphere.

Title: Improvements in or relating to automatic regulating means for mercury vapour rectifiers
IPC: H02M7/15
Filed: 1949-04-26
Abstract: 676,366. Automatic control systems; rectifying. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. June 16, 1950 [April 26, 1949], No. 11089/49. Classes 38 (ii) and 38 (iv). In a system for automatically controlling a variable, a reversible electric motor, the direction and speed of which is dependent on the sense and extent of departure of the variable from a desired value, operates a phase shifter controlling the output voltage of a grid-controlled mercury vapour rectifier, and manual means control the motor by overriding or displacing automatic control. A D.C. motor 10 driving a boiler house compressor 11 is supplied from an A.C. source 12 through a transformer 13 and a grid-controlled mercury vapour rectifier 14. A regulator 15 responsive to boiler pressure, which depends on the output of compressor 11, operates the slider 24 of a potentiometer 20 across a D.C. source 19 to control the sense and magnitude of the voltage applied to the armature of a D.C. servomotor 17 adjusting a phase shifter 16 in the grid circuit of rectifier 14 in the appropriate sense to maintain boiler pressure constant. To overcome friction and inertia effects so that slider 24 is brought to a central position when pressure deviations are corrected, latches 30, 31 attached to regulator 15 operate switches 28, 29 associated with tappings on potentiometer 20 to produce a reversal of the voltage applied to servomotor 17 when slider 24 passes its central position. When a changeover switch 23 is moved to the appropriate position automatic control is rendered ineffective and pressure may be controlled manually by pushbuttons 25, 26 which are then effective to operate servomotor 17 in either direction. Use of a reversible A.C. servomotor controlled by a saturable reactor is referred to.

IPC: B60G11/14
Filed: 1920-04-28
Abstract: 143,497. Astra Soc. de Constructions Aeronautiques. May 20, 1919, [Convention date]. Side-car attachments; tricycles.-A braking- device is applied to vertical shafts such as those carrying the trailing or independent wheels of cycles, tricycles, trailers, &c. in order to prevent excessive angular swing of the wheel should it leave the ground on striking an obstacle. and the consequent strain involved on retouching the ground in wrenching the wheel back into line with the leading or steering wheel. The shaft a carrying the forks of the trailing wheel is mounted to slide and rotate in a bearing-lug b on a bracket c secured to the box or body d. Secured to the lug b by means of screws is a casing e containing one or more disks f which are free to slide relatively to the shaft a, but are constrained to rotate with it by the engagement of a projection g in a key-way h cut in the shaft. One or more other disks i are slidingly secured to the casing e by screws k engaging recesses j in the disks, and are forced into frictional contact with the disks f by a spring l the pressure of which is adjusted by a screwed cap m. Should the trailer wheel leave the ground after contact with an obstacle, its tendency to swing about the shaft a, out of the true line of travel of the leading wheel, is restricted by the braking effect of the friction between the disks i, f.
