Title: Improvements in washing-boilers
IPC: D06F1/08
Filed: 1920-04-26
Abstract: 162,911. Ahlgrimm, (nÚe Gunkel), H., and Hochstrate, P. April 26, 1920. Washing-boilers.-The top of the boiler i is closed by a deep hood p, forming a steam chamber, which is separated from the boiler by a partition m having a central hole through which circulating tube l protrudes. An externallyoperated plate h, which has an extension piece n for the insertion of tube l, can be lowered, as in Fig. 2, to close the hole in partition m so as to divert the normal circulation over the clothes, to the upper side of partition m and thence to discharge spout a. The discharge spout mav be of the swivel type, the end when vertical being higher than the edge of the hole in plate m, thus preventing discharge of liquid. Steam vents b may discharge to atmosphere or to a condenser fixed above the hood p, so arranged that the condensed water drains back to the boiler.

Title: Addressing data stores
IPC: G06F17/30
Filed: 1964-03-19
Abstract: 1,030,253. Addressing memories; code conversions. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 19, 1964 [April 12, 1963], No. 11582/64. Headings G4A and G4C. In a data storage apparatus, a set of keys is mapped on to a smaller set of addresses by means for performing an algebraic transformation on each of said keys to provide a respective address, whereby keys separated by a Hamming distance of less than a predetermined amount are provided with different addresses. Referring to Fig. 1, a key K=(k0, k1, k2 ... k29) shifted into register 12 is converted into an address A=(a0, a1 . . . a4). Each element ki, ai is represented as six bits in parallel (and is an element of a Galois field-see Table I of the Specification). If the key K and address A are represented as polynomials K(X) and A(X) (the elements ki and ai being the coefficients of the terms thereof) the conversion may be represented where G(X) is a suitable (e.g. Bose-Chaudhuri) generator polynomial and Q(X) a quotient. The elements ki of the key K are shifted in turn into a chain of flip-flop sets 20-1 to 20-5, each set comprising six flip-flops. An element shifted out of set 20-5 goes to each of multiplier units 40-1 to 40-5, each of which comprises singlebit modulo-2 adders (i.e. exclusive-or gates) so connected that the output of the multiplier unit equals the input multiplied by one digit (coefficient) of the generator polynomial G(X). Each of the six bits of the output of each multiplier unit 40-1 to 40-5 is added modulo-2 to the corresponding bit of the next element ki approaching a corresponding flip-flop set 20-1 to 20-5, at a corresponding set of six modulo-2 adder units 32-1 or &c., the result of the addition entering the flip-flop set 20-1 or &c. When the last element k0 is shifted out of register 12, a counter and delay unit 15-2, after a short delay, enables a random-access memory 16 to respond to the contents of the fllip-flop sets 20-1 to 20-5, these being the required address. The multiplier units 40-1 to 40-5 are different from each other and have internal structures simulating the multiplicand, but as a modification each may be the same, comprising AND-gates and modulo-2 adder units and being supplied with the multiplicand over a set of six wires from a storage register. The key to address conversion may equivalently be represented by a suitable matrix [tij], thus: the matrix elements tij (each being six bits in parallel) being passed in turn to a single multiplier via a set of six delay line stores (one per bit position) and a six-bit register. The multiplier is also supplied with the key elements kj in turn from a shift register. When a given key element kj is presented it is multiplied by the appropriate five tij in turn, the answers being sent to five six-bit accumulators respectively. At the end, each accumulator is thus left storing one of the address elements ai (Figs. 8, 9, not shown).

Abstract: 719,700. Optical apparatus. KODAK, Ltd. Aug. 18, 1952 [May 18, 1951], No. 11668/51. Class 97(1) [Also in Group XL(b)] To determine the position of the focal plane of a lens light from an extended source is passed through a test object composed of opaque and transparent portions located approximately at the said plane, passes through the lens and is reflected back therethrough by an axially aligned prismatic member, to form an image of the target, the lens and target being relatively adjusted until the amount of light passing back through the target is a maximum in which position the target is in the focal plane. As shown light from a source 1 passes a lens 3 and illuminates the target 4 whence it passes to the lens 5 under test and is reflected back by a tetrahedral prismatic reflector 6. Light passing back through the target is reflected by a semi transparent mirror 2 for visual observation or measurement by photocell 7. The target 4 may be oscillated axially of the lens 5 the resulting varying current being fed through suitable phase selecting circuits to give an indication of the distance between the mean position of the target and the focal plane of the lens. The method may be used to test the location of an objective in a photographic camera.

Abstract: 456,119. Fluid-pressure servomotorcontrol systems. SULZER FRERES SOC. ANON., Winterthur, Switzerland. April 27, 1936, No. 11903. Convention date, May 6, 1935. [Class 135] In a power unit of the kind comprising a supercharged internal-combustion engine from which power is transmitted through electrical or hydraulic transmission apparatus, means are provided whereby, when the supply of supercharging air falls below a predetermined value, the supply of fuel to the engine and the torque transmitted are both correspondingly reduced, to prevent damage to the engine. The Figure shows an engine having cylinders 5 supplied with air under pressure by a compressor 1, and coupled to an electric generator B for transmitting the power, the fuel pump F being controlled by a member 10, which is acted on by a controlling-device E subjected to the supercharging pressure, and is connected through a lost-motion device 11 to a governor G, in turn connected by a rod 12 to a device H controlling the excitation current of the generator. The superchanging pressure acts through a pipe 7 on a diaphragm 6 controlling the valve 8, of a servomotor piston 9 connected to a bell-crank 21 acting on the control member 10. The rod 12 is connected by a lever 25 to the valve 13 of a servomotor piston 14 adjusting a rheostat 30 in the excitation circuit of the generator. A sleeve valve 31 surrounding the valve 13 may also be adjusted manually through an arm 32. For altitude regulation, an aneroid device may be connected to the diaphragm 6, or to a sleeve valve around the valve 8. Two springs may be arranged to come into action successively upon the diaphragm 6. In other modifications, the control E may be arranged between the governor G and the control H so as to adjust the effective length of the link 12, or the pivot of the lever 25 ; or the controls E and H may be combined in one device. In the case of a hydraulic transmission, the rod 12 controls the torque transmitted by a hydraulic coupling. In a multicylinder engine having several superchargers a control E and fuel pump F are provided for each supercharger, and each fuel-pump control is connected through a lost-motion device to the engine governor.

Filed: 1932-04-27
Abstract: 405,273. Variable - speed gearing; free-wheel clutches. LANSING, R. P., 11, Grove Terrace, Montclair, New Jersey, U.S.A. April 27, 1932, No. 12067. Convention date, April 28, 1931. [Class 80 (ii).] In a variable-speed gear, the direct drive and one geared drive may be transmitted either positively or through a screw-and-nut operated freewheel friction clutch as desired. The driving shaft 19, Fig. 1, carries rigidly a gear 38, while a gear 93 rotatable on the driven shaft 31 is driven at a reduced speed from the gear 37 on the driving-shaft through a gear 39, countershaft 32, and a gear 41. The free-wheel clutch 64 may be connected, between the driven shaft and either of the gears 38, 93 to give a direct and a reduced drive respectively. The clutch 64, see also Fig. 2, comprises annular plates splined alternately to a barrel 66 and to the nut 63, the screw 74 being keyed to a sleeve 77 splined to the shaft 31, a ball bearing 85 being interposed between the flange 83 on the sleeve 77 and a shoulder in the barrel 66 to take up the thrust of the screw. The movement of the nut is limited by a flange 80 on the screw and a shoulder 80a on the barrel, and at the other end by a lock-nut 75. The movement of the presser-plate 72 is limited by an annular stop 73 on the splined barrel 66, so that in the position shown the plates are just touching. On sliding the barrel 66 to the left, internal teeth 69 thereon engage the driving gear 38, and the slight friction between the clutch plates rotates the screw so that it moves to the left and establishes a driving connection by cumulative action, the torque-transmitting capacity of the clutch being, however, limited according to the pressure exerted by the springs 70 when the nut 63 comes against the stop 75. Further movement of the barrel to the left causes external teeth 77a on the sleeve 77 to engage internal teeth 100 on the driving gear 38, to give a solid drive. On sliding the barrel 66 to the right, internal teeth 88 thereon engage teeth 89 on a rigid extension 90 of the gear-wheel 93, giving a freewheel reduced drive. Further movement of the barrel to the right causes teeth 77b on the sleeve 77 to engage teeth 95 in the extension 90 to give a positive drive. A solid, further reduced drive and a reverse drive may be obtained respectively through gears 42, 43 on the countershaft 32 engaging directly or through an idler 54 respectively a gear 53 splined to the shaft 31. All the changes in drive may be effected by a single lever 115, which may be moved to engage a yoke 118 placed in a groove in the barrel 66, or to engage a collar on the shift-rod 30 of the gear.
