Filed: 1928-04-14
Abstract: 304,853. Butler, W. H. April 14, 1928. Clamping and guiding flasks.-Flasks comprise inner boxes a, of metal, aligned by means of frames b in which they are clamped. The frames may be of metal or wood with metal corner pieces o and one on each pair carries pins d while the other carries corresponding guides e which are adjusted by and fixed by screws k, h, Fig. 3. The inner boxes are secured in the frames b during moulding by screws c having engaging ends n, Fig. 2, loosely mounted therein to reduce friction. When the mould halves have been assembled the screws c are released and the frames b removed for use with other boxes a. More than two moulds may be superposed should the depth of the casting require it.

Abstract: 1,048,175. Feeding webs. PLAMAG PLAUENER DRUCKMASCHINENWERK VEB. July 9, 1965, No. 29238/65. Heading B6B. The tension control mechanism for the drive or brake of a web-roll includes a dancer roller 2 suspended in a loop of the web 1, Fig. 2 (not shown), said roller being journalled in slide pieces 5 and 6 attached respectively to endless chains 9 and 10. The tensioning bias of the roller 2 is achieved with a motor (17) driven induction coupling 16 with a selectably induced torque output, the output of the coupling being connected to the sprockets 11 and 13 of the chains 9 and 10. A potentiometer 22 or a detecting element such as a photo-electrically or electromechanically working induction transmitter is geared to the shaft 15 of the sprockets 11 and 13, and provides a control signal for the drive or brake mechanism. The motor driven induction coupling can also be applied to the pivot axis of a pair of levers supporting a dancer roller, to give the dancer roller the necessary tensioning bias.

Abstract: 687,607. Clip brackets. KLEIN, A. Nov. 30, 1950, No. 29408/50. Class 52(v) [Also in Group XXXVI] A clip bracket for supporting cables comprises a U-shaped retaining clip 1 with hooks to engage a support 2 and two spaced trough-shaped members 3, 4 fitting within the arms of the clip and encircling the cable, the member 3 having a wedgeshaped extension 5 which engages with a pivotally mounted plate 6 on the base of the U-shaped clip to clamp the cable in position. The troughs may have corresponding projections and recesses 9 to hold them together and may have bent-over portions 10 or strips attached to the top of the troughs to prevent the troughs dropping through the clip. To save space the width of the troughs does not exceed the diameter of the cable so the internal width of the clip corresponds to the diameter of the cable. A clamping screw or toggle mechanism may replace the wedge 5 and pivoted plate 6.

Abstract: 1321851 Data processing; process control TEXAS INSTRUMENTS Inc 18 June 1970 [22 July 1969] 29614/70 Heading G4A A data processor has a communication register respective bit positions of which control external devices, the processor being arranged to address individual bits of the communication register in order to control the external devices. A so called "bit processor" is added to a conventional computer operating, e.g. on a 16 bit word basis. The system operates in two modes, viz mode I which is conventional, and mode II in which single bit processing is performed both in the communication register and the system memory. The "bit processor" includes an arithmetic unit, a read only memory containing microinstructions, and several registers. Operation in mode I is, as stated, conventional under the control of a programme counter. Instructions are fetched in response to the programme counter and placed in an instruction register. A portion of the instruction specifies a memory address from which an operand is fetched and loaded in an accumulator. In mode II, in response to the incrementing of an event counter, the contents of a base register are added to those of the counter to specify a system memory address. The relevant instruction is fetched and placed in the instruction register. A part of the instruction is added to the contents of a communication address register to specify a single bit in the communication register. A softwave flag register is also provided to address the system memory by bit, the flag register contents being added to a part of the instruction register contents. The Specification describes the system and instruction format in some detail. Reference is made to U.S Specification 3,487,370, 3,400,371, and 3,248,701.

Abstract: 419,334. Switches held set and freed mechanically. WAYGOOD-OTIS, Ltd., 54, Fetter Lane, London. Oct. 26, 1933, No. 29701. Convention date, Feb. 10. [Class 38 (v).] Centrifugal actuation; retarding devices.- The control mechanism for the driving motor 70 includes switches 65, 66, Fig. 14, of which the latter inserts or cuts out a resistance 67 from the circuit including the field 68 and thus causes the escalator to run at the desired one of two speeds, and the former controls the energization of a magnet 71 which forms part of means by which contacts 72 controlled by a governor 73 are caused to separate and stop the escalator when it attains a speed which is a predetermined percentage in excess of the desired normal speed. In order that the contacts 72 may separate at a lower speed when the magnet 71 is energized than when it de-energized, a sleeve 75 of magnetic material, Fig. 11, is provided which rests on nuts 80 threaded on a rod 77 controlled by the displacement of governor collar 74, and is pivoted to a lever 78, Fig. 10. When the magnet 71 is energized the sleeve 75 is raised into engagement with a similar sleeve 76 which is secured adjustably to the rod 77, and less upward movement of the end of the lever 78 is required to effect the separation of the contacts 72 through a trip lever 116, and an arm and a spring. The governor controls also contacts 81 through a rod 119 and lever in such a manner that these contacts are separated when the escalator is stationary, engage when the escalator attains a speed suitably below the slowest normal operating speed, and remain engaged while the escalator operates at all speeds greater than the speed at which the contacts engage. These contacts break a circuit of the control system, and thereby cause an application of the brakes when the driving chain breaks. Each handrail 52 is provided with a switch which is actuated to stop the escalator by a trip mounted on the tightener wheel carriage 58 when further slack cannot be taken up by this device. Each handrail 52 is maintained taut by a weight 53 connected by a cable to the tightener wheel 54 through the intermediary of a rod 113, Fig. 9, which is prevented from moving towards the right by the engagement of a ball 110 with a tapering slot 111. Rotation of the step axles 25 with the chain wheels is prevented by arms 36, 37, Fig. 4, urged together by a spring. Side lugs 38, 39 on the arms engage the adjacent link of the chain 23. The toothed ends of the combplates 45, 46 are readily detachable without using tools, and adjustable vertically, this adjustment preferably being obtained by rotating each combplate about its base. Specification 420,490 is referred to.
