Abstract: 597,197. Lathe centres. BOLD,H. Aug. 13, 1945, No. 20708. [Class 83 (iii)] In a lathe centre, either male or bell-shaped, having hard metal inserts, strips of cemented tungsten or like carbide are brazed into tapered slots and recesses are cut between the strips to accommodate a lubricant such as grease. As applied to a male centre, the strips 5 are inserted into rectangular or undercut slots, which taper from rear to front, brazed to the body 1 and the bearing surface is then ground to the correct form. Between each strip a recess 6 is cut extending either the full length of the strips or shorter and deeper, and formed so as not to impair the security of the strips. The head 9 of a screw 8 and a washer 7 clamped by a collar 4 on a screwed shank 3 protect the ends of the strips and, in the case of the full length recesses, also retain the grease. The bell centre construction is similar.

Abstract: 1,102,186. Microphone circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 May, 1965 [20 May, 1964], No. 20738/65. Heading H4J. Signals from a microphone or group of microphones M2 and from a microphone or group of microphones M1 are applied to an amplifier 1 and 2 respectively in opposite phase, the outputs of which are divided between two paths, one path of each pair being connected to a potentiometer 5. The slidable tap of potentiometer 5 derives a difference signal which is fed to RC filter 6, 7, amplifier 8, RC filter 9, 10 and resistor 11. Potentiometer 5 is adjusted so that, as regards incident sound in the main direction of the microphone combination, no signal is passed on. Any signal passing resistor 11 is combind with a signal from amplifier 2, and which passes an adustable resistor 12, amplifier 14 and resistor 26. The resultant difference signal is fed to a low-pass LC filter 23, 24, having a cut-off frequency of 1500 c/s., the lower frequencies being passed via resistor 25 to output terminals 30, 31. Signal-to-noise ratio of the difference signal is improved by an amplifier 8, and two RC filters 6, 7 and 9, 10 provide a flat characteristic. The directional characteristic may also be adjusted by a resistor 12. The output of an amplifier 14 is divided between two paths, one containing resistor 26, and the other containing an adjustable resistor 15. The signal passing resistor 15 is combined with the amplified signal portion passing the resistor 17 in the output of amplifier 1, and the resultant sum signal is amplified at 19 and fed to a highpass filter 20, 21 of cut-off frequency 1500 c/s., the higher frequencies passing to the output terminals 30, 31. Microphone combinations.-In one arrangement one microphone M2 (Fig. la, not shown), has on each side a microphone M1. Alternatively, two microphones M2 are in the centre of a straight (Fig. lb, not shown) or curved (Fig. 1c, not shown) line including eight microphones M1. In other arrangements, four microphones M1 are at the corners of a square with a microphone M2 at the centre (Fig. 2a, not shown). Alternatively, nine microphones M2 are centrally arranged with respect to four groups, each such group consisting of six diametrically arranged microphones M1 (Fig. 2b, not shown). In a further arrangement having an annular characteristic, a central microphone M2 is arranged between two pairs of microphones Ml (Fig. 3b, not shown). The outer two microphones M1 face in the opposite direction to the inner two microphones M1. The microphones may be of the cardioid type.

IPC: G21C3/14
Filed: 1961-06-09
Abstract: 1,017,401. Fuel elements. ENGLISH ELECTRIC CO. Ltd. June 8, 1962 [June 9, 1961], No. 20889/61. Heading G6C. Two fuel elements are located one above the other, in predetermined relative angular orientation about a common axis, by means of a locating member fixed to one end of each fuel element and comprising at least one sloping guide surface and at least one thrust surface, the guide surfaces of the two elements cooperating to guide the elements towards the desired relative angular orientation and the thrust surfaces co-operating to maintain this orientation when the upper element is supported on the lower. Referring to Figs. 1 and 2, locating members 10, 11 screwed into the corresponding end portions of fuel elements 12, 13 each have three helical guide surfaces 18 joined by flat thrust surfaces 19, the member 10 also having a conical protrusion or cone 29 and the member 11 a corresponding conical depression or cup 28. The fuel element 12 is lowered on to the fuel element 13 in a vertical fuel channel of a nuclear reactor until the surfaces 18 of the member 10 engage those of member 11, this occurring before the cone 29 engages the cup 28, and is caused by its own weight on further lowering to turn with respect to the element 13 until the cone 29 is fully home in the cup 28. At this stage there is a slight clearance between the thrust surfaces 19 of the two locating members but this is taken up if coolant flowing past the helical cooling fins of the element 12 exerts a torque on the element, the guide surfaces 18 then being out of contact with each other. In either case the weight of the element 12 is taken by the cup 28 and the cone 29. The relative angular orientation of the fuel elements is determined so as to give the best heat transfer characteristics between the fuel elements and the coolant and the least loss of pressure in the coolant, preferably also to minimize vibration or movement of the elements caused by the coolant flow. In order to adjust the orientation of the locating members with respect to the fuel elements, shims 16, 17 may be inserted between them.

Abstract: 1,075,834. Potato-harvestens. AMAZONEN-WERKE H. DREYER. May 18, 1965 [May 26, 1964], No. 20914/65. Heading A1F. [Also in Division B2] A sorting device for a potato digging machine comprises a sieve frame 2 having two sieves 18, 22 mounted therein to define screening gaps, at least one of the screens being movable relative to the other to vary the gaps, and a frame 6 in which the sieve frame is resiliently-mounted by springs 3 and torsion blocks 5 for vibration by at least one connecting rod 8 and crankshaft 9, the position of which may be moved relative to the frame to adjust the inclination of the sieves. The upper sieve 18 is composed of parallel bars rigidly connected to the sieve frame 2. The lower sieve 22 is composed of parallel bars which are displaceable in the sieve frame by screwthreaded spindles and crank-handles 23; by operating the handles, the gaps formed by the bars of the two sieves can be adjusted. The crankshaft 9 of the vibrating mechanism is driven by the machine through sprockets 13, 11 and a chain 12 and its angular position may be adjusted by turning a rack 14 by means of a pinion 15 and handle 16. In operation, potatoes freed of most of the earth are fed from a sifting drum 25 on to the vibratory sieves in the sieve frame 2. The large potatoes slide down on to one side of a conveyer belt 26 for delivery to sacks or storage means. Small potatoes drop through the gaps between the bars on to a collecting sieve 27 which is formed of inclined bars 28 extending transversely to the bars of the sieves 18, 22; at the lower end of the bars 28 is mounted a receiving trough (29), Fig. 2 (not shown), which feeds the small potatoes to the other side (31) of a partition (30) on the conveyer belt (26). Potato tubers jammed between the bars of the sieves 18, 22 may be released by altering the position of the crankshaft 9 to cause vertical reciprocation of the connecting rod 8.

Filed: 1968-05-03
Abstract: 1,199,211. Refrigerating. SOC. ALSACIENNE DE CONSTRUCTIONS ATOM-- IQUES DE TELECOMMUNICATIONS ET D'ELECTRONIQUE. 3 May, 1968 [5 May, 1967], No. 21122/68. Heading F4H. In a refrigeration and/or gas liquefaction system of the type in which gas. is transferred back and forth between chambers of variable volume via a regenerator, the chambers are defined by eccentric members mounted for rotation in cylinders. As shown in Fig. 1, motors 3, 4 are mounted eccentrically within respective cylinders 1, 2 and co-operate with spring-biased blades to divide each cylinder into two chambers 1a, 1 and 2a, 2b. The rotors are driven about a common axis 15 and are 90 degrees out of phase. The chambers 1a and 2a are connected by a conduit system including a cooler 12a, a regenerator 7 and a load 11 while chambers 1b and 2b are connected via cooler 12b, regenerator 8 and load 11, so that two separate refrigeration cycles are performed with a phase difference of 180 degrees. In operation, considering the upper of the two cycles, gas is first compressed by simultaneous reduction of the volumes of chambers 1a 2a, then transferred from chamber 2a to chamber 1 by reducing the volume of 2a while increasing that of 1a by the same amount. The gas is then expanded by increasing both volumes simultaneously and is finally transferred from 1a to 2a, giving up its cold to load 11, by decreasing the volume of 1a while increasing that of 2a by the same amount. In a first modification (Figs. 3 and 5, not shown) the rotors are 180 degrees out of phase and serve merely to transfer the gas between the chambers, compression and expansion of the gas being effected by alternately connecting each circuit to a high pressure and a low pressure gas source at appropriate points in the cycle using a rotary distributor valve coaxial with the rotors. Coolers 12a and 12b are omitted. Such a system may include a plurality of low temperature stages as shown in Fig. 8 wherein 61 is the distributor valve, 52, 53, 54 are cylinders of equal volume and cylinder 51 has a volume equal to the sum of the volumes of the other cylinders. The rotors in cylinders 52-54 are all in phase and are 180 degrees out-of-phase with the rotor of cylinder 51. Two parallel multi-stage cycles having regenerators 55a, 56a, 57a and 55b, 56b, 57b, respectively, are thus provided and serve to cool loads 58, 59, 60 at progressively decreasing temperatures. A further distributer valve providing for the supply of high pressure gas from the coldest stage to a Joule-Thompson liquefaction stage and for the return of low pressure vapour from the latter may be included. The liquefied gas may be removed from the system or used for refrigeration. The spring-biased blades and the gas connections may be incorporated in the rotor (Fig. 6, not shown) which may be triangular, elliptical or lobed (Figs. 7a-7c, not shown). In the embodiment of Fig. 1 above, the rotors may be in phase and the blades angularly offset.
