Title: Reversible driving system
Inventor: BANCROFT NORMAN ROY
IPC: B66C13/23
Filed: 1960-11-17
Abstract: 989,170. Winch drives. PYE Ltd. Nov. 17, 1961 [Nov. 17, 1960], No. 39505/60. Heading B8B. [Also in Division H2] A reversible driving system for a crane or winch comprises a differential gear 3 having two input shafts driven from an A.C. motor 1, through an electromagnetic induction coupling 2, and reversing gears 4, 5 which provide an output speed half that of the motor 1. The speed and direction of rotation of the output shaft 6 is controlled by varying the speed of the shaft driven by the coupling 2 between zero and full motor value, this being effected by a speed control circuit 7, which varies the current through the excitation coil of the coupling 2, Fig. 2 (not shown) and which is controlled by a tachometer generator 8 driven from the coupling shaft. When the shaft 6 is used to drive the winding drum of a crane, hoisting or lowering corresponds to operation of the coupling 2 over the top or bottom half of its speed range. An electromagnetic brake 9 is fitted to the shaft of coupling 2 but is inoperative during hoisting and lowering of a loaded hook. When the shaft 6 is accelerated by the lowering of a light hook or upon rapid acceleration when lowering other loads, the acceleration of the coupling shaft causes the current through its coil to fall and so energize the coil of the brake 9, Fig. 2 (not shown). The brake 9 is thus applied until the coupling speed is restored to its set value, the braking torque being determined by the variation in coupling current. The coupling 2 may be similar to that of Specification 871,437, and the brake control circuit similar to that of Specification 948,467.

[Also in Division H1] A sealed magnetic contact unit 1 is closed when a condenser 3 is discharged through a control winding Yh on closure of a switch 5 in the control circuit, provided a winding X is already in the operative state. The winding X is a short-circuited winding which is energized by transformer action when the winding Yh is energized. If only one winding is energized the flux passes round the ring core 2 and not through the contact unit. The contact unit may be maintained closed by the continuous excitation of winding Yh as shown, or by a separate holding winding. A plurality of relays operated in the above manner may be employed in a coupling matrix (Fig. 2, not shown). In Fig. 3 (not shown), the contact unit comprises a magnetic reed contact 9 secured to the base of a C-shaped core 7 and movable between the polepieces of the core which also act as fixed contacts. The contacts are again enclosed in a sealed container and the winding Yh, which is energized by discharge of a capacitor 11 as before, surrounds the container whilst the winding X surrounds the core. A plurality of relays of this type may be used in a coupling matrix (Fig. 4, not shown).

Title: Frozen aerated dessert with a wrapper and stick and method of manufacture
IPC: A23G9/20
Filed: 1957-12-30
Abstract: 845,968. Frozen confections, chocolate preparations. ESKIMO PIE CORPORATION. Dec. 30, 1957 [Jan. 16, 1957], No. 40271/57. Classes 28(1) and 129. A frozen edible material, made mainly from water and containing at least 5% by volume of non-toxic substantially insoluble gas, is made into a bar, wrapped and pierced through the wrapper and a handle is inserted into the piercing to pin the wrapper to the bar. An ice-cream bar 10 is formed by extruding the ice-cream and cutting it into bars which are then coated with chocolate, e.g. as described in Specification 738,185. Alternatively the bar may be moulded and the chocolate may be omitted or replaced by e.g. caramel. As shown, the wrapping 14, e.g. foil or foil laminate, and preferably a rectangular sheet of foil laminate lined with paper, is wrapped round the bar with an overlap along one side. The tapered end of a blade 20 is thrust through the centre of end 16 and forms a recess 26 in which a stick 24 is inserted. The wrapping and piercing preferably take place immediately after the chocolate coating has been applied. The temperature of the bar should not be so low as to make it brittle and is usually between 10 ‹F. above zero and 20 ‹F. below zero when the blade is inserted. Preferably 70% to 90% by volume of the liquid mix is air in ice cream and ice milk, 25 % to 40 % is air in sherbet and the like with little or no butterfat, the extreme range being 5% to 120%. The temperature of blade 20 must be much higher e.g. 90‹F. or lower than that of the icecream so that the latter does not adhere to it. In Example 1, 85 % by volume of air is whipped into a liquid mix of 11 % by weight of non-fat milk solids, 12% butterfat, 15% sugars, 0À5% stabilizing materials, e.g. vegetable gum and gelatine, 0À5 % flavouring materials and 61 % water as the mixture is cooled to 20 ‹F. It is then extruded, cut into bars and the ambient temperature lowered to 45 ‹F. below zero after which the bars are enrobed with chocolate at about 100 ‹F. (e.g. 22% chocolate liqour, 55% other vegetable oils, 18 % sugar, 4 % milk powder made up to 100% with salt, emulsifying and flavouring materials). The coated bar is wrapped in a sheet of paper laminated to aluminium foil and is pierced at one end by a blade heated to about 85 ‹F. and a stick is inserted in the opening. Two further examples are given using the same method but different mixes, that of Example 2 including banana puree. Reference has been directed by the Comptroller to Specification 701,927.

Title: Process for contacting a hydrocarbon liquid with a gas comprising hydrogen
Inventor: JOHANSON EDWIN S
IPC: B01J8/22
Filed: 1960-11-23
Abstract: Hydrocarbon liquids, especially petroleum distillates containing at least 0.5% by weight of sulphur, are treated with a gas comprising hydrogen, e.g. to effect desulphurization, and are passed upwardly therewith through an expanded bed of solid particles maintained in random motion within a continuous liquid phase, liquid and gas being withdrawn therefrom free from the solid particles.  As shown, gas and feedstock are passed by 1 to heater 3 and thence to reactor 5 which contains an "ebullated" mass of a hydrogenation catalyst, e.g. nickel molybdate, or (preferably) cobalt molybdate on alumina, the rate of flow being such that the bed is expanded to 10-50% more than its settled volume.  In general, the particle size of the bed is 0.01-0.25 inch and the catalyst has a bulk density of 25-50 lb./ft.3. The reaction conditions are 550-850 DEG  F., 500-3000 p.s.i.g., a liquid hourly space velocity of 2-40 vols./vol. of expanded bed and a liquid flow rate of 10-70 gallons/min. per sq. foot of bed area.  The reaction mixture passes through screen 9 which retains particles of catalyst and then enters separator 12; liquid leaves by 14 <PICT:0966915/C4-C5/1> and vapour, from which hydrogen may be recovered for reuse, by 13.  Part of the liquid may be recycled with the feed by line 16. When the feed is a distillate of boiling range 400-900 DEG  F., the hydrogen is used at a pressure of 500-1500 p.s.i.g. and in amounts of at least 700 S.C.F./bbl. oil.  For distillates at least 20% of which boil above 650 DEG  F., the pressure used is 1000-1200 p.s.i.g. and the liquid hourly space velocity 2-20 vols./vol. For heavy oils boiling above 650 DEG  F. not less than 6 vols. of treated oil are recycled per vol. of fresh oil charged and before recycling, the treated oil is stripped of hydrocarbons boiling below 650 DEG  F., hydrogen being used in an amount of 125-200 S.C.F./bbl.

Abstract: 1,129,348. Suction lifting devices. VACULIFT MASCHINENBAU G.m.b.H. 5 Sept., 1967 [4 Nov., 1966], No. 40433/67. Heading B8H. A suction lifting device has a piston 17, 18 which is raised into an annular chamber 16 and is sealed to the chamber by a rolling diaphragm 19 clamped to the chamber by rings 20, 21 and to the top of the piston by rings 22, 23. In operation the device is placed on the article to be lifted and raised by a ring 35 attached by chains 33, which pass round pulleys 32 on the piston rod 27, to arms 34 on top of the cylinder. Thus the vacuum produced is twice as powerful as it would be with the lift applied directly to the piston rod. As air enters the inside of the cylinder due to leaks round the seal 12 the piston continues to rise until it abuts and opens a valve 37 which sounds a warning whistle. The device has an automatic valve in the base of the piston rod which ensures that suction develops only on alternate lifts so that loads are automatically released on being set down. The piston rod has a lost motion connection with the piston so that lifting and lowering causes rotation of a horizontal steel pin by means of off-set teeth on a pair of sleeves. The pin supports a valve 43 which is alternately opened and closed on alternate lifts when the pin falls alternately into deep and shallow slots in the lower sleeve.
