Patent GB-1028731-A (GB)
Title: Improvements in or relating to the preparation of liquid shortening
IPC: A23D9/02
Filed: 1963-08-02
Abstract: The invention comprises a process for preparing a liquid shortening wherein an oil, which is a blend of a liquid vegetable oil with a semi-solid shortening fat, is heated, e.g. to 140 DEG  to 160 DEG F., to complete the melting of the fat and then cooled to cause crystallization, the oil being de-aerated prior to cyrstallization. Preferably de-aeration takes place during the heating step by subjecting the oil to vacuum with agitation after which the oil is rapidly cooled to below 60 DEG  F.  After cooling the oil may be warmed to about 80 DEG  F. at a rate of 1 DEG  F. per minute. Cottonseed, peanut and soybean oil are used as vegetable oils and the shortening fats specified include lard, modified lard and mixtures thereof with lard and partially modified lard or hydrogenated cottonseed oil.  Emulsifiers may be added in amounts of 1 to 6% by weight of the liquid shortening, e.g. vegetable and animal monoglycerides, tallow or lard monoglycerides, glyceryl lactostearin or lactopalmitin, and propylene glycol monostearate; and the ratio of the vegetable oil to semi-solid fat is approximately 1:1.

Filed: 1965-07-23
Abstract: 1,082,266. Endless conveyers. GENERAL ELECTRIC CO. Ltd. July 15, 1966 [July 23, 1965], No. 31650/65. Heading B8A. Articles continuously fed from an endless belt 1 are accumulated on a belt 2 by holding the latter belt stationary and moving supporting pulleys 6, 7 from right to left. An article adjacent the end of belt 1 is thus transferred to belt 2 by the " unrolling " of belt 2. The pulleys 6, 7 are mounted in a carriage 8 which carries an article sensing switch 11. Further pulleys 12, 13 for the other ends of the belts are carried in a carriage 14. A motor M1 provides the continuous drive for the belt 1 and a motor M2 which drives a pulley 5À1 is controlled by the sensing switch 11. As each article reaches the switch 11 the pulley 5À1 is rotated anticlockwise and the " unrolling " action of the belt 2 results. The carriage 14 moves correspondingly to the carriage 8 but in the opposite direction. The period of operation of the motor M2 is so chosen that the articles accumulating on the belt 2 are spaced and do not damage each other. When the required number of articles has been accumulated they may be discharged by braking the drive to the belt 1, releasing a pulley 17 previously holding the belt 2 stationary, and driving the pulley 17 by a motor M3. This discharge sequence may be initiated by an article counting mechanism C. The belts are tensionsed by weight and hydraulic means, respectively. Support for belts 1, 2.-As shown, pulleys 19, 20 are provided but in Figs. 2, 3 (not shown) the belts are further supported by a pair of endless roller chains (21) the rollers (22) of which run on guide tracks (23). Pulleys (24) extend between the chains to support the belts 1, 2. The arrangement is particularly suitable for dealing with bricks prior to firing i.e. when they are in a soft state.

The heat-exchanger 9 tends to maintain constant over a range of load variation the temperatures of the air at entry to the turbines 5, 8 or turbine stages, and so compensates for differences in heating in the two heater groups that occur when the load varies, because of the different load-temperature characteristics of radiation-heated and convection-heated heaters.
Patent GB-1237013-A (GB)
Title: Braking force regulators
Inventor: KORM ARMIN
IPC: B60T8/18
Filed: 1968-07-03
Abstract: 1,237,013. Brake-force regulators; loaddependent brake regulators. BARKAS-WERKE VEB. 3 July, 1968, No. 31786/68. Heading F2F.  A braking force regulator (preferably dependent on load) for a vehicle's fluid brake system, comprises a piston 2 slidable in a casing 1 and having pressure faces 15, 16 of different surface areas operative in opposite directions, and a passage 11 connecting the faces. The smaller face 15 may communicate with a fluid inlet chamber 8 fed from a reservoir, while the larger face communicates with a fluid outlet chamber 12 connected to brake operating means. A valve plate 10 urged by a spring towards the smaller face 15 is contacted by the piston 2 to restrict fluid flow through the regulator when the piston has been displaced a predetermined amount by pressure at the outlet reaching a given value. As shown, the piston 2 is in its rest position, where it is held against a stop 13 by the resultant force of a compression spring 3 and a tension spring 5, the tension spring acting on a yoke 4 which forms the right-hand abutment for spring 3. In this position the smaller face 15 is spaced from the end of the bore in the casing 1 which communicates with the fluid inlet chamber 8. When the brake pedal is applied, fluid under pressure enters chamber 8, flows through peripheral apertures 9 of the spring-loaded valve plate 10, enters the bore, flows along axial passage 11 in the piston 2 to the outlet chamber 12, and passes from there to the brake(s). As the outlet pressure builds up the piston 2 is forced to the left until the smaller face 15 makes contact with the valve plate 10, whereupon the fluid flow is restricted or completely cut off. If the brake is released or eased, the pressure of the fluid in axial passage 11 pushes the valve plate 10 away from the end face 15 to release the excess fluid between the piston 2 and the brakes. As the fluid pressure diminishes, the piston returns to its rest position. The outer end of the spring 5 is attached to an anchor point movable automatically in an adjustment range 6 in dependence on the load on the vehicle. If the regulator is provided in the brake lines for the rear wheels, for example, the anchor point may be on a lever connected to the centre of the back axle stabilizer. A light load causes the spring 5 to be more highly stressed than a heavy load, so that the flow of fluid is cut off at a lower pressure.

IPC: H02P9/00
Filed: 1919-12-18
Abstract: 153,270. Maschinenfabrik Oerlikon. Oct. 30, 1919, [Convention date]. Drawings to Specification. Dynamos and motors combined for transmitting power.-In a power transmission set comprising turbine-driven generators and polyphase induction motors, the torque is regulated, during the period of starting, by varying the speed of the turbines and also varying the resistances and connexions of the motor. Both variations are effected jointly by a common control element of the kind described in Specification 152,896. The invention is designed for propelling vehicles and ships. One method of procedure is : first, to run the turbine up to half speed before putting on the electrical load; secondly, to put on the electrical load gradually, keeping the turbine at constant speed until the vehicle-speed has reached half its full value; thirdly, to run the turbine, and with it the vehicle up to full speed. During the second stage, the motors are changed from cascade to parallel or their pole-numbers are varied. The Specification is accompanied by diagrams of power-speed curves corresponding to the invention.
