Title: Apparatus and method of fermenting beer
IPC: C12C11/00
Filed: 1956-12-21
Abstract: <PICT:0801658/III/1> <PICT:0801658/III/2> For removing foam from fermenting beer, a fermenting tank has an inclined roof, a baffle having its top edge below the roof and which divides the tank into a beer chamber and a foam chamber, and an inclined ramp, e.g. a screen, extending angularly downward from the top of the baffle into the beer chamber.  A tank 1 is partitioned by a baffle 17 to form a fermenting chamber 2 and a foam chamber 3.  A second baffle 231 is fitted parallel to the baffle 17 such that its top edge 25 is approximately 111 below the low point 15 of the roof 14; a screen 26 is mounted on the tops of the two baffles.  In operation, chamber 2 is filled with beer up to the level of the top edge 25 of the second baffle.  As foam forms on the beer and as the volume of the beer increases during fermentation, the space between the beer and the roof 14 decreases and the slope of the roof presses the foam towards the inclined screen 26 and up the inclined surface to the top edge 19 of the baffle 17; beer carried with the foam drains back into the chamber 2 through the screen.  The foam condensed in the chamber 3 is removed through an outlet 20.

Title: Operating Device for an Artificial Limb
IPC: A61F2/72
Filed: 1967-08-29
Abstract: 1,192,982. Operating device for an artificial limb. NETHERLANDS ORGANISATION FOR APPLIED SCIENTIFIC RESEARCH ON BEHALF OF PUBLIC HEALTH. 29 Aug., 1967 [30 Aug., 1966], No. 39469/67. Heading A5R. [Also in Division H3] An operating device for an artificial limb includes a body pick-up electrode capable of picking-up signals from a muscle, means for deriving controlling signals from the picked-up signals, and a fluid valve arranged to be operated by a source of power in response to a controlling signal to permit a discrete quantity of fluid to operate the limb. As shown, the device comprises a part I adapted to be connected by electrodes 1, 2 to a flexor muscle on the body and a pant II adapted to be similarly connected to an extensor muscle, the two parts picking up electrical signals from the muscles and modifying the signals so that they control valves 10, 16 which cause the fluid pressure above a piston 13 connected to the artificial limb to be either increased or decreased. An electrical pulse provided by the part I causes the valve 10 to open so .that a discrete quantity of fluid passes from the pressure vessel 12 to the space above the piston and an electrical pulse provided by the part II causes the valve 16 to open to atmosphere so that a discrete quantity of fluid escapes from the space above the piston. Each part I or II (see also Figure 3, not shown) comprises body electrodes 1, 2 coupled to a differential amplifier 3 so that interence is minimized and so that pulsed signals (Fig. 2A, not shown) of varying amplitude are obtained, optionally a rectifier 4 or differentiating circuit (19), a low pass filter (20), a chopping circuit 5 with an adjustable threshold so that a part only (Fig. 2B, not shown) of the pulses are retained, a differentiating circuit 6 which sharpens the pulses (Figure 2C, not shown), optionally a divider circuit 7 which reduces the number of pulses transmitted (Figure 2D, not shown), a shaping circuit 8 which provides the pulses with a constant width. (Figure 2E, not shown), and a power amplifier circuit 9 which is connected to a solenoid (96) actuating the valve 10 or 16.

Title: Improvements in voltage regulators
IPC: G05F1/573
Filed: 1959-11-24
Abstract: 941,516. Automatic voltage control systems. GENERAL PRECISION Inc. Nov. 24, 1959 [Nov. 24, 1958], No. 39845/59. Heading G3R. [Also in Division H3] A voltage regulator of the series transistor type has an auxiliary transistor which so biases the series transistor as to prevent the emitter current of its series transistor exceeding a safe value. The transistor 3 is in series between a source 1 and a load 2. A portion of the load voltage is tapped off a potential divider 9 and compared with a reference source 8 in the base/ emitter circuit of a transistor 7. The base current of the series transistor 3 is provided by an auxiliary source 13 through a resistor 11 and the collector of a normally saturated n-p-n transistor 12. The collector current of transistor 7 also flows through resistor 11 so that as the load voltage falls and the collector current of 7 decreases so the base current of 3 increases to tend to correct the load voltage. With increasing load current, the load voltage drops until transistor 7 is cut off. With increasing collector current transistor 12 ceases to be saturated and passes a constant current determined by emitter resistor 13 and base bias 15. The transistor 3 is thus controlled also to pass a constant current. In a modification, Fig. 3 (not shown) the emitters of transistors 3 and 12 are linked by a resistor so as to obtain an output characteristic in which the load current falls with reduction in load resistance. In a second modification Fig. 5 (not shown) the bases of transistors 3 and 12 are also connected to form an emitter-coupled bi-stable circuit.

A wet-press for a papermaking machine and comprising upper and lower press rolls between which a wet web of paper is carried by an endless loop is modified to facilitate changing of the felt. The lower press roll is mounted on and parallel to a cantilever frame, the upper press roll is mounted on a separate support and can be moved away from the lower roll, and several loop-supporting rollers are also mounted on the cantilever frame, but so that they can be moved between an extended position, where they engage the loop, and a retracted position. As shown, the press comprises rolls 15 and 20 and felt loop 25. Two press beams (one shown) 10 and two cantilever beams 11 form a frame, the outer end of which can be normally supported on removable blocks 13. The roll 15 is mounted on this frame, but roll 20 is mounted on two lever arms (one shown) 21, pivotally mounted on posts (one shown) 23, so that it can be lifted away from the roll 15. Four loopsupporting rollers 26, 30, 38 and 39 are mounted on arms 27, 31, &c., pivotally supported between the beams 10 by pins 28, 33 &c. Gear wheels 29, 32 &c., are also mounted on these pins and the two at each end mesh with one another and one of them with a third gear wheel 33 on shaft 36, provided with means (not shown) for manual rotation. A fifth loop-supporting roller 40 is mounted in fixed bearing 41, and a sixth 45 on swing arms 46 to tension the felt. To change the felt, rolls 20 and 45 are swung away from the felt, the blocks 13 are removed, and shafts 36 are turned to swing rollers 26, 30, 38 and 39 inwards towards roll 15 (Fig. 3, not shown). The felt loop can then be removed, a new one installed and the rollers then moved back in reverse order.

Abstract: 1356821 Shaping container ends CROWN CORK & SEAL CO Inc 26 Aug 1971 [22 Oct 1970] 40151/71 Heading B3Q The open end 10 of a container 12 is deformed whilst pressurized fluid is applied to the interior of the container. Apparatus for deforming the open end 10 of the container 12 having side walls and a closed end 16 comprises a fluid source 25 under pressure, a die 14, means 24 for applying said fluid to the interior of a container, a platform 18 opposite the die for supporting the container, which platform includes a supporting surface 26 and a positioning surface 28, and means 20 for moving the die relative to the platform in order to engage the open end of the container. The open end of the container is received between opposing die surfaces 32, 34 by downward movement of movable slide 20. The fluid under pressure enters the interior of the container for purposes of stabilizing and aligning. The supporting surface 26 is provided with a spring 54, and application of pressure by the fluid causes depression of the surface 26 to allow the frusto-conical portion 30 of the container to engage the positioning surface 28 of the platform 18. Pressurized fluid continues to be applied to the container interior to prevent collapse while the open end 10 is deformed by a portion (37), Fig. 1c (not shown) of the outer die surface. The surface 32 of element 38 is held in place on the slide by a threaded cap 40 while a bolt 44 maintains contact between die element 42 and slide 20 and also provides the passageway 24 for the pressurized fluid. Seals 46 are provided to ensure that the fluid pressure is maintained. The upward motion of a piston 48 of the platform is limited by a ring 50 via ears 70, 72 which contact each other prior to the application of fluid. A yoke may be provided to prevent the container from falling off the supporting surface 26, and further embodiments relate to a flanging die (140), Fig. 2 (not shown) and a deburring die (142), Fig. 3 (not shown). The inner die surface (146) of the flanging die is curved downwardly so as to produce a suitable flange on the container, and the outer die surface (232) of the deburring die is completely cylindrical, mating with the inner die surface so as to completely remove burrs on the container ends. All these embodiments may be utilized in a system, Fig. 4 (not shown), whereby the containers are pre-sized, necked-in in two stages so as to reduce the chances of fracture, and finally sized.
