IPC: F24F11/00
Filed: 1962-05-29
Abstract: 958,627. Valves. WOODS OF COLCHESTER Ltd. March 6, 1963 [May 29, 1962], No. 20645/62. Heading F2V. [Also in Division F4] A ventilating fan comprises a fan and driving motor mounted within a short duct and pivoted louvres which close the duct when the fan is not in operation and are opened by the action of a solenoid which is switched simultaneously with the motor. As shown in Figs. 1 and 2 connected louvres 48 are opened against a spring 52 by an arm 44 pivoted at 45 and having a roller 46 bearing on a plate 47 of one of the louvres 48. The arm 44 is rocked by a segmental pinion 42 which is connected through a spring 38 with an arm 35 rocked about a pivot 36 by the core 32 of a solenoid 31. The spring 38 serves to allow the solenoid core 32 to move normally if the louvres become jammed. In a modification, Figs. 3 and 4 (not shown), the two arms are pivoted about a common axis and directly connected by a spring so that they normally move in the manner of a bell crank. The solenoid in either case is mounted with its axis horizontal and may be connected in series with the fan motor, or if the latter is of a capacitor run three lead reversing type the solenoid winding may be divided into two equal parts connected across the two motor windings. Alternatively the solenoid may replace the condenser. According to the Provisional Specification the louvres may be gravity biased towards their closed position, they may be provided at the inner or the outer end of the duct, may be mounted in a casing removable from a part -holding the solenoid assembly and may be made by injection moulding of plastics material. The removable casing may also be of plastics material and may be held in place by a spring catch. The louvres may be actuated by a bellcrank lever, one arm of which is a leaf spring acted on by the solenoid core without being attached to it.

Abstract: 690,571. Driving sound reproducing machines. THORENS SOC. ANON., H Aug. 21, 1950 [Sept. 5, 1949], No. 20658/50. Class 40 (ii) [Also in Group XXIV] The speed of a gramophone turntable 1 is changed by moving an arm L to one of three positions where a lug 21 on the arm engages in a notch 18, 19 or 20. Movement of the arm rotates a plate S about a sleeve 7 to bring one of three members O<SP>1</SP>, O<SP>2</SP> or O<SP>3</SP> into driving engagement with the intermediate friction wheel R that drives. the turntable. The member O<SP>1</SP> is driven directly by the motor shaft 5 and the members O<SP>2</SP>, O<SP>3</SP> are driven from the member O<SP>1</SP> by a belt C. The diameters of the parts of the members O which drive the wheel R and which are driven by the belt C are arranged to give the required driving speeds. The wheel R is carried by a lever 24 which is longitudinally displaceable by a pin 25 and slot 26 and pivotally mounted about the pin 25. A spring 23 holds the wheel R in contact with the turntable and the driving members O. The angle between the radii passing through the points of contact of the wheel R with the turntable and a driving member O remains constant for each driving member. A spring Fig. 4 (not shown) holds the lug 21 in one of the notches. The motor is secured to the frame resiliently. In a modified apparatus Figs. 6 to 8 (not shown), each of the three driving members O are driven by a belt from the motor shaft. In a further modification the motor shaft is coaxial with one of the driving members and the motor is mounted on and moves with the plate S. The tension of the belt C may be adjusted by making the mounting of one or more of the driving members movable (see Fig. 9, not shown). The driving, member may be moved to a position in which the turntable is not driven.

Filed: 1965-05-17
Abstract: 1,060,055. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 17, 1965 [June 25, 1964; June 26, 1964], No. 20844/65. Addition to 1,055,840. Heading H1C. The active medium of a laser is common to. a plurality of optical cavities angularly displaced from each other, an electro-optical light shutter being included in each cavity so that an effective output may be obtained along a single selected light path. As shown in Fig. 1, the active medium 9 may be a spherical solid such as ruby, the medium serving as a lens which directs light between plane mirrors 6a, 6b, 6c and corresponding focal points in a spherical mirror 7. All the light paths 5a, 5b, 5c so defined include.a light shutter comprising a polarizer 20 and a nitrobenzine Kerr cell 15 having electrodes 16, 17, the paths 5b, 5c including, in addition, respective compensators 25, 26 which introduce different degrees of fixed phase delay. As the Kerr cell itself causes a phase delay of polarized light which is related to the potential applied to electrodes 16, 17, all but a selected one of the paths are " Q-spoilt " by appropriate selection of the Kerr cell potential. Either the mirror 7 or the mirrors 6a-6c may be partially light transmitting, and where the various light paths are located in a single plane the active medium need not be fully spherical. In a modification, Fig. 3 (not shown), the mirror 7 is formed as a coating 7<SP>1</SP> on a part-spherical end surface of an active medium in the form of a cylinder with domed ends. In an alternative arrangement plane reflecting surfaces are formed by facets on the active medium, a Kerr cell being common to all the light paths in Fig. 5 (not shown), while each light path has a respective Kerr cell 17a, 17b in Fig. 4 (not shown). The latter Figure includes a thyratron 31 and associated resistancecapacitance circuit 29, 37, 38 which enables two light paths 5a, 5b to be alternately operable in response to signals applied to a control terminal 33. Polarizers need not be used in the embodiments if the active medium emits polarized light. Two light pumping sources 10, 10<SP>1</SP>, Fig. 1, are described, but as an alternative a helical light tube may be used.

Title: Improvements in or relating to the removal of free moisture from substances by centrifugal means
IPC: B04B15/12
Filed: 1923-08-21
Abstract: 217,469. Elmore, G. H., (Comley, R. C.). Aug. 21, 1923. Strainer separators; discharging. - Free moisture is eliminated from substances by treating them in a centrifugal drier and causing the treated material, after leaving the rotor, to travel a sufficient distance through the air to dissipate the remaining moisture. The centrifugal drier is of an ordinary type in wihich the wet material is fed from the spout 14 to the space between two conical rotors 5, 8 the outer one 8 of which is perforated for the passage of water. A trough 15 receives the water which passes through the rotor 8 and supports the outer casing 17. The enclosing wall 16 of cement, metal or wood rises from the foundation 1 at least to the level at which the treated material leaves the rotors 5, 8. By reason of its high velocity the escaping material travels outwards from the rotors in a. nearly horizontal sheet, and the particles then drop until they reach the face of the wall 16 at an acute angle and slide down its surface. The dry material is collected in an annular bed 18 which is rotated by means of conical gears 22 the teeth of which engage teeth on a track plate 19 secured beneath the bed 18. A curved deflector 25 is carried by a bracket 26 on the casing and by the outer wall 16. This deflector reaches across the rotating bed 18 and guides the dry material to an opening in the wall 16. In a modification, the rotors are provided with annular extension sections 30, 31, Fig. 4, with their lower edges turned outwards and slightly upwards so that the escaping material is thrown upwards to obtain a longer travel before reaching the wall. The rotors may be placed with their bases uppermost and the air may be treated to keep it dry.

Title: Improvements relating to Calculating apparatus
Inventor: DELI GEORGE CHARLES
IPC: G06F7/491
Filed: 1966-05-12
Abstract: 1,169,931. Digiter serial adder. MULLARD Ltd. 12 May, 1967 [12 May, 1966], No. 21154/66. Heading G4A. A calculating apparatus operating in serial manner includes a plurality of bi-stable elements arranged to receive data via a plurality of gating arrangements and to receive data directly, the elements being controlled by means operating them sequentially and individually and feeding back the output of each element through the gating arrangement to affect the information presented to the next following operative bi-stable element. Data held in a magnetic core store 20 is fed via an amplifier 21 and OR gate 22 to a flip-flop 24 which in turn feeds AND gates 29-32 which also receive inputs from a carry flipflop 35. Two AND gates 31, 32 are enabled by a line 34 when a positive operation is to be carried out, and the other two by line 33 when a negative operation is to be carried out. The gates then feed a set of Q flip-flops via lines JK, the other of two numbers to be added being entered directly via the set and reset lines S.R. The Q flip-flops are enabled consecutively by clock pulses on lines CP0-CP4 and the outputs feed sets of AND gates 60-69 also enabled by the said clock pulses, which then feed further AND gates connected to the carry flip-flop. For an addition each bit of the A number is combined with the appropriate carry bit B in AND gates 31, 32, acting as an exclusive OR gate. If one only of the bits is " 1 " a signal is applied to the J, K inputs of the flip-flop enabled by the appropriate clock pulse to change the state of the flip-flop. If both bits are " 0 " or " 1 " the Q flip-flop remains unchanged. The number stored in the Q flip-flops is thus the result and may be read out via lines 80-84. The carry bit is set via AND and gates 73, 75 for addition. A carry occurs if any two or all three of A, B, Q are " 1." If all three are " 1 " or A and Q are " 1 " the B flip-flop is set via the J line. If B and A or Q are " 1 " no signal appears on either the J or K line and the B flip-flop remains set on 1." For no carry to occur all A, B, Q are " 0 " or one only is " 1.' If A and Q are zero and B = 0 or 1 the flip-flop is reset via the K line. If A or Q are " 1 " and B=0 the flip-flop remains at " 0." Thus the arrangement shown correctly adds two binary members in serial fashion. For subtraction gates 29, 30, 72, 74 are enabled. Feeding the OR gate 22 is a correction circuit 23 serving to render the adder suitable to add binary coded decimals or sterling, a plurality of AND gates serving to enable appropriate lines of a decoding matrix to cause the appropriate correction factors to the four-bit number, the fifth bit serving to indicate the carry bit.
