Abstract: 562,204. Valves. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd., and SMITH, C. H. Dec. 14, 1942, Nos. 17755/42 and 6004/43. [Class 135] A butterfly valve is actuated through gearing arranged so that the flow through the valve increases uniformly with the angular movement of the hand wheel or the like over the whole range of opening movement of the valve member. The Figure shows the invention applied to a valve device actuated alternatively by a hand wheel 6 or by a remotely controlled power device 30. The circular valve member 3 is mounted on a spindle 3<1> carrying an arm 12 connected by a link 13 with a pivot or arm on a gear-wheel 8. The wheel 8 meshes with a smaller wheel 7 loosely mounted on the shaft 3' and rigidly secured to a hand wheel 6. The valve is held in its adjusted position by a friction grip comprising a flange 17 on the hollow boss of the wheel and pressed, by a spring 24, against a plate 29 secured to the casing. When it is desired to make the power device 30 operative, a knob 20 is pressed to the right to release the tension of the spring 24 and to move a blade 19 to couple the flange 17 with a member 19a mounted on a lay shaft 9b. A chain 33 maintained under tension by a spring- loaded lever 37 passes round a toothed wheel 35 on the lay shaft and a toothed wheel 32 loosely mounted on a spindle 31. This spindle is attached to a diaphragm in the casing 30 and is held against rotation by a bracket 39 fixed to the spindle engaging a rib on the casing. The knob 20 and a plate 26 secured to the wheel 8 are provided with pointers co-operating with fixed scales. In a modification, actuated solely by hand, the gear-wheels are arranged at the opposed side of the casing to that on which the arms and link are situated. In place of the connection described above, chain or cam gear may be utilized.

Title: Improved control means for compression refrigerating apparatus
IPC: F25B49/02
Filed: 1929-06-11
Abstract: 313,881. Chabal, P. June 18, 1928, [Convention date]. Operating clutches and friction wheels.-The friction clutch 3, 4 between the shaft 1 of an internal-combustion engine and the compressor shaft 2 of a refrigerating machine is controlled through a pivoted lever 11 by a spring-urged locking rod 19 and a centrifugal declutching device 18 driven by an electric motor 23 controlled by a thermostat 31 disposed in the refrigerator. In the locked declutched position shown, the disc 4 of the clutch is held out of contact with the disc 3 by the pins 12 on the boss 14 of the lever pressing against a ball-bearing 13 which abuts against a flange 9 formed on the sleeve 5 which slides upon a polygonal extension of the compressor shaft. To start the machine, the pressure of the pins is relaxed by the disconnection of the handle 34 of the rod 19 from its stop 35 through a cord 41 and a pivoted lever 40 by a projection 39 on a hand-operated rod 38, the stop 45 for the handle of which is released through the cord 44 and the pivoted lever 43 by the projection 42 on the rod. The release of the pressure of the pins results in the disc 4 of the clutch being pressed by the spring 7 into contact with the disc 3 and the starting of the compressor. When the thermostat 31 in the refrigerator reaches a predetermined low temperature the circuit through the electromagnet 30 is broken and the completion of the circuit through the electric motor 23 effected by the spring 32 making the point of interruption 27, 28. The rotation of the declutching device 18 forces the end 15 of the lever 11 to the left and breaks the contact between the discs 3, 4 of the clutch. Upon a rise of temperature in the refrigerator, the circuit through the motor is broken and the clutch disc 4 is again forced into contact with the disc 3 by the spring 7 to re-start the compressor. Dashpots 20, 48 are provided to ensure smooth working of the mechanism. In a modification, a disc friction gear is substituted for the friction clutch. More than one compressor may be driven from a single shaft by the use of a corresponding number of de-clutching devices.

Title: Arithmetic apparatus
IPC: G06F7/535
Filed: 1970-04-15
Abstract: 1,246,592. Arithmetic circuits. INTERNATIONAL BUSINESS MACHINES CORP. 15 April, 1970 [25 April, 19691, No. 17934/70. Heading G4A. Arithmetic apparatus with parallel input obtains digits of the reciprocal of an input number by combining the input digits and products of them obtained by logic gating means, or (claimed separately) obtains digits of a quotient each as a sum of products of a dividend digit with a factor, factors being obtained recursively as sums of products from the divisor digits and factors. In a first embodiment, the reciprocal of a first parallel binary number (which may be a divisor) is obtained based on expressing each binary order of the reciprocal in terms of the difference of two sums of digits and products of digits of the input number. Combinatorial logic using AND gates produces the products (since the product of two or more bits is their AND). Two trees of carry-save adders and half-adders receive the digits and products of digits for the two sums respectively (in all orders), the tree outputs being subtracted by complemented addition to provide the reciprocal. The reciprocal can be multiplied in a parallel binary multiplier by a dividend to obtain a quotient. The quotient is then justified to take account of initial left-justification of dividend and divisor. In a second embodiment, a serial-parallel network of adder and multiplier units obtains factors of the form: from inputs - D n  where D n  is a typical binary digit of a parallel divisor and P 0  = 1. A second serial-parallel network of adder and multiplier units combines these factors P n  with the binary digits N n  of a parallel dividend to obtain quotient digits q n  according to: The adder units may be implemented as trees of carry-save adders.

Abstract: 391,643. Driving machines; workholders. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE, 8, Rue des Vieux- Grenadiers, Geneva, Switzerland. June 30, 1932, No. 18560. Convention date, May 6. [Class 83 (iii).] In a device for adjusting the table of a machine tool such as a boring or milling machine, of the kind in which a rough adjustment is made by a double-acting fluid pressure piston and the final adjustment by a manually operated mechanical device, the piston is locked in position as soon as the fluid pressure is cut off therefrom and the mechanical device then operates relatively to the fixed piston. The stationary cylinder 8 contains a double-acting piston 19 whose rod 18 is screwed at 20 to engage an internally-threaded worm wheel 21 rotatable in, but fixed axially relatively to, a bracket 22 on the work-table 41. A distributing valve 3 has connections 1, 2 to a pump and exhaust respectively, connections 6, 7 to opposite ends of the cylinder 8, and a connection 5 to pistons 10, 11 which act on spring collets 13, 14 for locking the piston-rod 18. Movement of the valve 3 by a hand-lever 40 from the mean position shown in Fig. 1 admits fluid to one end or the other of the cylinder 8, thereby moving the table 41 to approximately the required position, whereupon restoration of the valve to the mean position locks the pistonrod 18 and allows the final adjustment to be made by manual rotation of the worm 24. A bolt 27, Fig. 2, is actuated by a hand-lever 26 and nut 25 to clamp the table 41 to the bed 42. A second arm on the lever 26 is connected to a slide valve in the casing of the valve 3 whereby, when the table is clamped, the fluid is byepassed freely from the supply 1 to the exhaust 2 and the cylinder 8 cannot be actuated. Hydraulic or pneumatic pressure may be used.
