Title: A coupling for transmitting rotary motion and imparting lateral displacement to a driven member
IPC: B25D11/06
Filed: 1924-08-12
Abstract: 242,706. Hage, R. A. Aug. 12, 1924. Percussive tools. - Comprises link-work mechanism for conveying rotation to a member and simultaneously imparting thereto a bodily displacement so that its centre of gravity traces a closed path, and is applicable to hammer-disc mechanism of the kind described in Specifications 164,752 and 207,272. [both in Class 83 (iv), Metals, Working]. The device may be embodied in an electrically driven percussive rock drill, in which case the lateral reciprocating motion of an intermediate part may be utilized to operate twist mechanism and a pump for removing debris. In this device a hammer disc 34 is driven from a rotary shaft 1 through as intermediate shaft 27 mounted in a bearing plate 28 which is vertically slidable in a guide partition 29. A combined rotary and vertical reciprocatory motion is imparted to the shaft 27 from the shaft 1, and a disc 39 on the shaft 27, acting through pins 35, 36, 37 (Fig. 9) engaging kidney shaped slots 46, 47, 48 in the hammer disc 34, imparts to this member a rotary motion combined with a bodily displacement such that its centre of gravity traces out the kidney-shaped path 32, the hammer being raised slowly and lowered relatively quickly. If desired, the pins 35, 36, 37 may be additionally supported by an idle disc 38 on a shaft 40 mounted in a second vertically slidable bearing plate 41. To impart rotary and lateral reciprocating motion to the shaft 27, the shaft 1 carries a driving plate 2 formed with curved slots 11, 12 in which blocks 9, 10 are adapted to reciprocate, the blocks being linked by bars 7, 8 to a common pivotal stud 5 on the driving plate and being also pivotally connected to eccentric sheaves 15, 16 mounted on fixed eccentric bearing discs 17, 18, adjustably secured to the casing 4. The eccentric constraint causes the blocks to reciprocate in their slots as they rotate with the driving plate 2. This motion is transmitted to the shaft 27 through a pair of bare 22, 23 pivotally connected at 13, 14 to the slide blocks 9, 10 respectively, and slidable in grooves at right angles formed across the face of a disc 26 on the shaft 27.

Abstract: 183,128. Marguerre, F., and Hausmann, M. July 12, 1921, [Convention date]. Hot-water storage apparatus; generating by direct contact of steam; caustic-soda and like boilers.-In a steam-generator subjected to varying demands, excess heat is taken when the demand is low to a storage vessel by means of a steam pipe or a water-circulating pipe, and the stored heat is used when the demand is high to heat the feed-water. The heat-storage vessel a, Fig. 1, is charged by excess steam led from the generator d by a pipe k. The vessel contains a pipe coil b through which the water from the economizer f may be passed before entering the generator. The steam pipe may also open into an ordinary heat-storage water container n, Fig 2, the two branches s, t of the pipe being fitted with non-return valves or the like, the branch s serving to introduce the steam into the container and the pipe t serving to withdraw it. The valves controlling the charging of the storers and the valves controlling the passage of water through the pipe coil may be operated by devices acted upon by the pressure or temperature of the boiler steam. Other types of storage vessels such as those containing salt solutions may be used in place of the water container n. The stored heat may be partly used for heating purposes instead of being returned to the generator.

Filed: 1936-07-10
Abstract: 459,031. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 10, 1936, No. 19193. Convention date, July 12, 1935. [Class 38 (iv)] Frequency.-A system for obtaining a constant frequency supply from a variable frequency source comprises a wound secondary induction motor, to the rotor of which a mechanical load is applied proportional to the secondary circuit voltage and to the secondary is applied an electrical load proportional to the secondary frequency, these loads controlling the motor speed such that the secondary frequency remains substantially constant. The motor 13 is connected to the variable frequency supply 10 and on its secondary side to the network 11 to be supplied at constant frequency. The motor shaft is geared to a hysteresis brake 15, the braking action of which is varied by a winding 18 supplied from the network 11 through a rectifier 17 so that the braking is dependent on secondary voltage. The secondary load dependent on frequency is formed by a condenser bridge 14. The arrangement is such that if, e.g. the frequency tends to rise, the load current drawn by 14 increases and the braking action by 15 reduces, thus causing the slip of the motor 13 to reduce and restore the frequency of the system 11 to normal. In a modification, a standard frequency source formed by a tuning fork generator is used. Any phase difference between the supply 11 and the standard causes adjustment of the grid potential of a rectifier valve which supplies the winding 18 of the brake 15. U.S.A. Specification 1,522,216 is referred to.

Title: Improved indicating device for weighing and computing scales
IPC: G01G23/32
Filed: 1937-07-13
Abstract: 481,482. Weighing-apparatus. ZEISS IKON AKT.-GES. July 13, 1937, No. 19421. Convention date, March 24. [Class 143] In an optical indicating device for a weighing and computing scale employing a movable transparent chart, the beam of light after passing through a lens manually adjustable across rows of numerals on the chart, is divided by a semi-transparent fixed reflector, the passing and reflected rays being led by further reflectors to projection apertures at different sides of the housing. As shown, a load placed on the scale pan 6 rotates a transparent disc 9 a proportional amount. The disc bears outer rings of weight graduations readable from opposite sides of the machine through apertures 25, 25<1>, and a series of inner rings of monetary values corresponding to various prices per unit weight. Images of the value graduations are projected by an optical system on to screens 20, 21 at opposite sides of the machine, the optical system being arranged to give normal reading of the values at both screens. For the screen 20 the system comprises a lamp 10, two condenser lenses 11, 12, mirrors 14, 17, projection lenses 15, 19, semi-permeable reflector 22 and mirror 23. For the screen 21, the rays proceed by the same path except that they are reflected at the semi-permeable reflector 22 on to a V-shaped mirror 24 and thence on to the screen 21. The V-shaped mirror reverses the image laterally so as to give normal reading on the screen. The lenses 12, 15 and mirrors 14, 17 may be adjusted vertically as a whole by means of an external knob which at the same time sets the price per unit-weight indication on graduated scales 26, 261.

Abstract: 442,827. Tensioning loom warps. GRIMM, O., 73, Hauptstrasse, Lengenfeld, Germany. July 8, 1935, No. 19506. [Class 142 (ii)] In weaving fabrics with densely - picked weft threads, the tension of the warps corresponding to each heald is changed rapidly at the beat-up while the last picked weft is held and is being pushed over or under the preceding weft. The tension of the warps is changed by back rests 6 .. 9 oscillated by cams 27 .. 30. The cams may be shaped to produce the slackening of the warp in stages. Examples are also given for weaving with two and three healds. In the latter case, the back rests are operated so that for each shed one set of warps is taut, another slackened, while the third is loose. The cams are operated by chain gearing from the crankshaft 33.

Title: Multi-processing system having means for dynamic redesignation of unit functions
IPC: G06F11/00
Filed: 1973-04-25
Abstract: 1402942 Data processing systems BURROUGHS CORP 25 April 1973 [12 May 1972] 19780/73 Heading G4A In a multi-processing system having a plurality of processing groups each with processor, memory and I/O control units, sensing of a malfunction in any unit causes a distress signal to be sent, via a redesignator unit for the corresponding processing group, to a reconfiguration control unit which re-specifies the functions of the various units. A plurality of processing groups A, B each of which includes a central processor 10, memory module 12, an I/O control unit 11, a remote terminal data communications processor 13, a disc file optimizer 14 which determines the sequence of data transfers to or from disc files, and a maintenance and diagnostic processor 15. Each group also has a control unit 22 which includes a redesignator unit receiving control signals from a designation memory 35, which may be readonly or read/write, contained in a reconfiguration control unit 20. The various units of a processing group are interconnected by a scan bus 18, and the processing groups may be coupled together into sub-systems by a scan bus configuration unit 23 which places constraints on the manner in which the groups can be interconnected, while units 22 control the actual reconfiguration operations. Each unit 22 passes on unit designations from control unit 20 to the units in its processing group and verifies that the assignments are correct and mutually consistent within the subsystem to which the processing group is assigned. The units 22 co-operate with each other to coordinate operation of two or more groups in a subsystem. In response to distress or failure signals from a processing group or to an input from manual console 19, the associated redesignator unit 22 causes the designation memory 35 to address its next control word location to specify a new system configuration in an attempt to restore at least partial system operation. The distress or failure signals to which units 22 respond may arise from recursive interrupt occurring in a processor unit, a predetermined number of successive unsuccessful half/load operations, power failure, inproper system configuration code assignments (implemented by unit 23), and unsuccessful linkage of properly assigned groups, e.g. left and right neighbours of adjacent units should be complementary.  Permissive configuration mode is one in which the various processing groups designated for a particular sub-system will only be connected into the sub-system if they are available, i.e. if their power is on and they have not been placed in a "local" mode. Removal and re-instatement of resources may be initiated by the operator. The MCP may assemble statistics on the operation of peripheral devices and request permission to run test routines on a particular device whose operation is suspect. Specification 1,402,943 is referred to.

Title: Improvements in or relating to method of dialysis and a dialyzing apparatus
IPC: B01D61/24
Filed: 1939-07-07
Abstract: 530,952. Dialysis apparatus. PFAUDLER CO. July 7, 1939, No. 19831. Convention date, July 13, 1938. [Class 1 (i)] Dialysis is effected by causing the liquids to flow on opposite sides of a membrane without creating any pressure thereon other than the necessary osmotic pressure. Preferably the liquids flow by gravity along the membrane in unsupported thin films. In one suitable apparatus, Fig. 4, a long length of membrane 34 is folded over a series of bottomless frames 31, and the liquids are supplied to alternate chambers by spray pipes 44 which direct them on to the surfaces of the membrane down which they flow. From the compartments 38 which are closed at the bottom the liquid escapes by apertures 39 in the sides of the frames to a trough 41 delivering to a vessel 43. The other compartments discharge directly into a trough 37 and vessel 42. Fig. 23 shows an alternative form in which the membranes 153 are inclined. The liquid is directed on to both upper and lower membranes of each chamber. In the case of the upper membrane the liquid is held by cohesion until it drops off at the apex into troughs 157. In another form of apparatus, Fig. 4, the membrane constitutes the periphery of one or more drums 168 which as they rotate dip into a supply of one liquid and so collect a film of it on the outside. The other liquid is applied to the interior through the hollow shaft 167 and similarly forms a film on the inside. Scoops 177 collect the liquid from inside the drums.

Title: Elevator system
IPC: B66B3/00
Filed: 1974-05-07
Abstract: 1473518 Protecting transistors from overload WESTINGHOUSE ELECTRIC CORP 7 May 1974 [8 May 1973] 20060/74 Heading H3T [Also in Divisions G3 and H2] In a lift system, hall indicator lamps are energized by driver circuits from a supply which limits current flow to a valve which is less than that which would otherwise initially flow when a lamp is switched on. The object is to protect transistors used in the driver circuits. The lamps are connected in a matrix comprising rows energized by logic driver circuits such as that shown at top right of Fig. 4A, and columns energized by broadly similar driver circuits (Figs. 4B, not shown). Power to the row drivers is supplied from circuit 78 which comprises transistors 260 ... 266, the current through which is limited by a Zener diode 274 in the emitter circuits of 260, 264. The normal (hot) lamp current is such that these transistors are saturated, but the higher current at switch-on, although limited, is sufficient to drive the transistors out of saturation; the resulting increase in voltage drop across output transistors 262, 266 causes a second Zener 276 to become non- conducting which turns off a further transistor 270 to produce a logic one on a terminal 318. This starts a monostable timing circuit 330; if this times out before the current drops to normal a short circuit fault is assumed and another transistor 268 is made non-conducting to turn off the power supply, by change over of a flip-flop 340. The faulty circuit is disconnected by a "driver inhibit" circuit 86. When the supply is turned off by 268, 270 again becomes conducting (by a voltage through Zener 276 and resistor 306) so that the flip-flop is reset and the supply restored, to energize the next row when the lift car moves. Fig. 4 relates to a 6 flow installation but a modification of the matrix to accommodate 128 flows is described (Fig. 5, not shown).
