Patent GB-163261-A (GB)
Abstract: 163,261. Marks, E. C. R., (National Equipment Co.). Nov. 4, 1919. Disc mills; feeding granular and like materials. -Means for delivering cocoa nibs or the like to a pair of hoppers comprises a measuring hopper positioned above and between the hoppers and adapted to be oscillated so as to supply measured charges alternately to the hoppers. The invention is shown applied to a reducing and refining apparatus of the kind described in Specification 161,210 and consisting of a reducer B, refiner C, and liquor conducting and treating device D for delivering the liquor from the reducer to the refiner. The cocoa nibs &c. are fed through apertures 17 in the stationary grinding-discs 14, 15 from a pair of hoppers 18 supplied from an oscillating measuring-hopper 19. The hopper 19 is carried by pivoted arms 20 and is oscillated over a curved shield 22 by a rod 26 connected to the pin 28 of a crank 29. The crank 29 is oscillated by a link 31 connected to a bell-crank lever 34, 35 actuated by a link 36 connected to an eccentric pin on the face of a wheel 39 driven by a wheel 40 on the shaft 10 of the rotary grinding-disc 13. The shield 22 bridges the gap between the hoppers 18 and is provided at the ends with upstanding walls 23. The outlet portion of the hopper 19 lies between the walls 23 and has apertures 24, provided with adjustable gates 25, for the passage of the material. The agitating-rods 41 have pin-and-slot connections with cranks 42, 47, the crank 42 being mounted on the pivot-pin 30 of the crank 29 and the crank 47 on a shaft 46 carrying a crank connected by a rod 44 to the pin 28 of the crank 29.

Abstract: 145,434. Gastambide, J., and Gastambide, R. March 19,1917, [Convention date]. Planes, construction of; steering and balancing. -To enable the planes of an aeroplane to be varied in area, camber, and angle of incidence, they are made in two or more superposed parts having cylindrical surfaces of contact so that one part may be slid relatively to the other in the direction of flight. Fig. 5 shows a plane formed of two parts A, B extending right across the machine through slotted guides in the fuselage. The surfaces .in contact are arcs of a transverse cylinder having its axis at 0, to which axis all the necessary bracing may pass so that it may not be disturbed by movements of the parts A, B. In cases where the axis O is inconveniently distant, sliding connexions may be provided in the stays. The planes may be moved in their guides by means of toothed sectors or other means. Figs. 6, 7 and 8 show other forms of compound planes, the form shown in Fig. 7 having five parts.

Abstract: 476,605. Railway light signals. SHIPP, D. G., MACGREGOR, R. M., and WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. June 13, 1936, No. 16552. [Class 105] The spectacle of a light signal in changing from the caution aspect to the clear aspect is moved further in the same direction, the operating mechanism comprising two motor elements of the induction vane type ; the motor elements may be energized separately to move the spectacle to the caution and clear positions or may be energized together so that the spectacle moves to the caution or to the clear position according as the two torques act in opposition or in agreement. The operating means shown in the Figure comprises a core 4 with a part of the pole face shaded by a short-circuiting band 11 and a composite core 5, 8 of which the limb 8 is energized by a "local" winding 9. The core 4 gives a clockwise torque and the composite core 5, 8 gives a torque clockwise or anticlockwise according to the instantaneous relative polarity of the " control winding 7 on the limb 5. With the torques in opposition the spectacle moves to the caution position. With the torques in agreement the spectacle moves to the clear position. The induction vane 3 of the spectacle may be arranged so that it only enters the gap of the composite core 5, 8 on the occurrence of a movement by the energization of the core 4 and thus the local winding 9 need only be energized after a certain degree of movement. The motor elements may each be of the type with part-shaded poles and energized separately to give the two movements. The vane spindle has a cam 12 and a crank 13 to operate the levers 14, 15 of indication contact devices,

Abstract: 502,552. Coin - freed article delivery apparatus. BRUS, G. J., and NAAMLOOZE VENNOOTSCHAP LANDRE & GLINDERMAN'S WERKTUIG-EN GEREEDSCHAPHANDEL. June 16, 1937, No. 16715. Void. Convention date, June 16, 1936. [Class 27] Articles stored in piles.-Cartons of ice-cream 10 are stored in a number of side-by-side, columns in a thermally insulated compartment cooled by refrigerant in a container 3. The lowermost carton of each column rests in a cup 14 carried by a delivery drawer 12, the succeeding carton being supported, when the drawer is pulled out, by a spring-actuated stirrup 19 bearing against the rear of the cup 14. A flap 15 rises behind the drawer when open to prevent entry of warm. A single coin mechanism located in a chamber at normal temperature outside the article compartment - controls all the drawers, operation of more than one drawer at time being prevented by a row of blocking elements 16 between which abutments on the drawers pass when pulledout. When the last carton has been removed from a column, a follower weight 31, by means of a connecting chain 32, throws over a lever 34 which actuates a detent to lock the drawer of that column. Articles cut from the mass.-In a modification, a bar of ice-cream rests in each delivery cup 14, and a knife element on the cup cuts a portion off the lower end of the bar on opening the drawer, a stirrup as above supporting the remainder of the bar whilst the drawer is open. Coin action, with stationary coin forming abutment.-The wedge-shaped end of the end blocking element 16<1> engages between a pair of levers 24 pivoted at 25 and drawn together by a spring 26. The upper ends of the levers receive the inserted coin between them. Their lower ends have interengaging fingers 27, 28 to ensure equal movement. Initial opening of a drawer in the absence of a coin causes the blocking element 16<1> to pass between the levers 24 until the levers enter slots at either side of the blocking element near its end and lock it. Further opening movement of the drawer is then prevented. If, however, a coin is present between the levers, they are unable to drop into the slots in the blocking element and the drawer can be opened fully. The blocking element widens beyond its slots so as to force the levers apart at the end of the opening movement to release the coin. The coin mechanism is located in a chamber outside the cooled article compartment. A heat conducting. rod, however, connects the two compartments and its end within the coin mechanism chamber is located near the coin mechanism to prevent condensation of moisture thereon.

Abstract: 644,535. Gravity switches. WARREN, E. M. June 23, 1948, No. 16915. Convention date, June 30, 1947. [Class 38(v)] A safety switch for interposition in the ignition circuit of a vehicle comprises a housing containing a movable steel ball adapted to close or open a switch and cut off the ignition should the vehicle tilt beyond a predetermined angle. Fig. 2 shows a plan of one embodiment wherein the housing 10 is V-shaped and flared from one end 14 so as to form two channels at right angles along which the ball 18 may roll. At the outer ends of the channels, switches 20 are mounted, each comprising a headed plunger 24 carrying a contact 23 and pressed outwardly out of engagement with an inner contact plunger 29 by a spring 28. Said switches are connected between the magneto and earth. When the switch is mounted horizontally on a vehicle, the ball normally rests at the junction of the channels as shown but abnormal tilting of the vehicle laterally or rearwardly causes the ball to engage one of the plungers 24 thereby closing its respective switch 20. For battery ignition circuits the switches may be constructed as in Fig. 5. In this case they are normally closed and each comprises a resilient strip 43 carrying a contact 42 engaging a contact 45 mounted on an insulated terminal 46. The ball on engagement with strip 43 bends it outwardly and opens the switch. The Specification as open to inspection under Sect. 91 describes another embodiment wherein the housing comprises a tube with a single switch mounted at one end. In this case the switch is actuated only by tilting of the vehicle in one direction, i.e. along the length of the housing. This subject-matter does not appear in the Specification as accepted.
