Title: Process for the extraction of proteins from vegetable protein meals
Filed: 1941-10-27
Abstract: Saturated protein solutions are prepared from vegetable protein meals by introducing a quantity of said meal continuously or in successive fractional batches into such a quantity of an aqueous acid, alkali or salt solution, capable of dissolving vegetable proteins, as will give with the said quantity of meal a substantially saturated protein solution, and separating the deproteinised meal from the solution, the rates at which the meal is introduced into and the deproteinised meal separated from the solution being such that the ratio of the weight of meal present in the solution to the weight of solution at any one time is sufficiently small, for example, 1 : 50 to 1 : 60, to enable the particles to move freely in the solution during their lexiviation. In an example, 50 tons coconut meal is treated with 25-30 tons of a 6 per cent aqueous salt solution, the meal being added in 0.5 ton portions and the deproteinised meal being removed before addition of the next fraction of meal by passing the suspension of meal from the extraction zone to a separation zone, suitably comprising a centrifugal filter or vibrating screen, and recycling the filtrate back to the extraction zone to remove any protein flocculates.  The clear saturated filtrate ultimately obtained may be treated to isolate the dissolved protein by addition of the salt used in preparing the above-mentioned aqueous salt solution.

Title: Improvements in or relating to window washing devices for mechanically propelled vehicles
IPC: B60S1/50
Filed: 1955-05-16
Abstract: 775,329. Air pumps on motor vehicles. BOSCH GES., R. May 16, 1955 [July 3, 1954], No. 14008/55. Class 79(3). [Also in Groups XXIII, XXV and XXVIII] Relates to an air pump for operating a window washing device on a motor vehicle (see Group XXIII). The window washing device comprises a container 1, Fig. 1, for washing liquid and a diaphragm air pump 3 to pressurise the liquid in the container to urge the liquid along a supply line 6 past a control valve 7, the pump being operable by the suction in the inlet manifold 5 of the vehicle internal combustion engine. The air pump 3 is mounted on the mouth of the container and is connected by a pipe 4 with the intake manifold 5 of the vehicle engine. Referring to Fig. 3, the air pump 3 comprises upper and lower chambers 24, 25 separated by a diaphragm 22, urged to the position shown by a spring 26. The chamber 25 is formed in the base 31 of the pump which base has a bore 28 communicating with the outside atmosphere and controlled by an inlet valve 27, and a bore 30 communicating with the interior of the container 1 and controlled by an outlet valve 29. Another bore 38 in the base 31 connects with the supply pipe 6 and by a pipe 39 to a point near the bottom of the container 1. Positioned between the base 31 and the mouth of the container is a gasket 32 having a depending tube 37. The tube 37 prevents the filling of the container beyond the level 40, Fig. 3, so that some air is always trapped in the top of the container. In operation when the vehicle throttle is only slightly open and there is maximum engine suction, the diaphragm 22 is raised against the spring 26 so that air is drawn through the bore 28 and valve 27 into the chamber 25. When the throttle opening is increased suction is reduced and the spring urges the diaphragm to the position shown in Fig. 3, to expel the air from the chamber 25 through the outlet valve 29 and bore 30 into the container. When the pressure in the container reaches a predetermined value the back pressure on the diaphragm opposes its motion and balances the differential effect of the maximum suction in the manifold 5 and the spring 26, so that the pumping action ceases.

Title: Control system for a machine tool
IPC: B23Q15/00
Filed: 1971-06-12
Abstract: 1362971 Automatic electric control of grinding machines LANDIS TOOL CO 12 June 1971 [12 June 1970] 14412/71 Heading G3N A control system for moving a machine tool element through a cycle of operations by means of a pulse motor which is supplied with a selected one pulse train from a plurality of pulse trains of different repetition ratio and means are provided to supply only a predetermined number of pulses so that the element is moved a predetermined distance at a speed selected by the repetition rate of the applied pulse train during an operation within the cycle. The effective sequence of control is provided by the sequence control counter 45 which provides enabling signals to the pulse repetition rate selector switches 55 so that the required feed speed is obtained. It also enables the respective end switches 56 relating to the particular operation being carried out so that the end point of the tool in relation to the workpiece is set. Additionally it enables dwell switches 57 whereby the element is held stationary for a pre-set period after completing an operation. The switches 55, 56, 57 are set by the operator before machining commences and the setting is preferably signalled as binary coded decimal. On completion of an operation which is indicated when the number of pulses sent as counted by counter 70 is equal to the pre-set count in end point selector 62, there will be an output from comparator 72 which will advance the sequence counter 45 to the next step. When the element dwells the comparator 76 compares the output of oscillator 65 with the output of dwell selector 74 and an advance pulse is obtained when these inputs are equal. In the embodiment described the machine tool element is a grinding wheel which is moved rapidly by an hydraulic valve and is fed by an electro-hydraulic pulse motor. The system uses binary coded decimal signals throughout and has means to display the actual diameter of the workpiece at any instant. Five feed speeds are selected for sidewall grinding, fast approach, No. 1 feed, No. 2 feed and fine feed and the 400 KHz crystal oscillator output is divided to 40KHz and 4KHz before being applied to a rate multiplier to give the output pulse trains having repetition ratio to give the five pre-set speeds above. A motor current transducer detects the rise in grinding wheel drive motor current when the wheel touches the work and causes the transition to the No.1 feed speed. A measuring caliper is provided whose output controls the transition to the fine feed speed operation. The remaining transitions are controlled by the settings of the end point switches. The pulse motor is mechanically coupled to a pulse generator and the generated pulses compared with the input pulses to the motor so that if the motor lags a difference count results which can be used to retract the grinding wheel and stop the machine.

Title: Refuelling of nuclear reactors
IPC: G21C19/20
Filed: 1972-03-29
Abstract: 1373677 Fuelling reactors UNITED KING- DOM ATOMIC ENERGY AUTHORITY 28 March 1973 [29 March 1972] 14912/72 Heading G6C A reactor has a core constructed and arranged so that fuel may be added to the core whilst the reactor is on-load without the need for discharging irradiated fuel from the core. As shown, the reactor 10 is of the high-temperature, gas-cooled type having a core 11 contained within a steel-lined pressure vessel 12 of prestressed concrete. Standpipes 13 afford access to the top face of the core 11 by means of refuelling machines 14a, 14b, for on-load and offload refuelling, respectively. The core 11 is formed of columns of interchangeable units comprising prismatic graphite blocks 15, 16, the blocks 15 containing nuclear fuel in the form of fission product-retaining coated particles while the blocks 16 are devoid of nuclear fuel and are disposed around the fuel-containing blocks 15 to serve as neutron reflectors. Vertical channels 17, 18 extend vertically through the blocks 15, 16 to provide channels for the reactor coolant (helium), the channels 18 being of larger diameter than the channels 17 and accommodating control rods 19 operated by drive mechanisms 20. The coolant is circulated down through the reactor core 11 and up through heat exchangers 23 housed within the wall of the pressure vessel by means of circulators 22. Each block 15 (Fig. 3) is penetrated by a plurality of coolant channels 17 and a single control channel 18, the fuel being contained in the form of cylindrical compacts 29 within holes 30, each compact 29 comprising spherical fuel particles coated with layers of pyrocarbon and SiC in a graphite matrix. The blocks 16 are of similar form but without the fuel (Fig. 4, not shown). The upper face of the core 11 is initially bounded by a double layer of reflector blocks 16 and progressively, in an on-load operation, the lower of the two upper blocks 16 of each column is replaced by a fuel-containing block 15. After a further period of operation, the reactor is shutdown for off-load refuelling, after which the core columns are as they were at start-up. By means of this scheme, the shut-down frequency for refuelling can be half that for an entirely off-load refuelling scheme, only new fuel and unfuelled reflector blocks are handled on-load thus eliminating many of the hazards and difficulties of normal on-load refuelling, and new fuel is always concentrated near the top of the core where, with the downward coolant flow, the coolant temperature is lowest and where partially inserted control rods can be employed to suppress local power peaks.
