Title: Improvements relating to manifolding and copying apparatus
IPC: B41L3/14
Filed: 1945-02-26
Abstract: 597,519. Book-keeping devices. ZSOLNAI, T. Feb. 26, 1945, No. 4808. [Class 16] A manifolding or copying apparatus such as described in Specification 571,620 is modified in that the clamp for the record cards, instead of being fixed to the rack is adjustable independently of the rack and can be fixed in a number of different positions and is provided with a stop for locating the card relatively to the summary sheet and to the slips or envelopes in the magazine. As shown, the baseboard, the magazine, the rack and the mechanism for operating the magazine and rack are as described in the above-mentioned Specification. A clamping bar 101 hinged at 102 to the rack 3 and locked to the rack at its other end, holds the summary sheet 117 and carbon sheets, projections 104 on the rack passing through holes in the sheets and into recesses in the bar 101. The edges of the bar 101 are dovetailed to engage a slot in the underside of a block 105 which carries a plate 106 having a horizontal slot to receive a record card 118, the slot having a stop 112 for the card at one end. The record card is clamped by pins 107 projecting through holes in the upper part of the plate 106 and carried by springs 108 attached to a bracket 109. Levers 111 carried by the bracket 109, when depressed on to the springs 108 between the bracket 109 and the stops 110, raise the outer portions of the springs and the clamping pins 107. An extension 114 of the block 105 houses a spring-pressed ball adapted to engage in one of a series of holes 116 in a stationary plate 113 attached to the casing. Thus while the summary sheet 117 under the clamping bar 101 is moved up by the operation of the handle 10 at each entry, the successive record cards 118 are located by the stop 112 in the plate 106 in the same position so long as the block 105 is not moved, i.e.. until it is desired to make entries on another line of the record cards, e.g., the next weekly entry. In an alternative arrangement the spring-pressed ball device is replaced by a rocking bar mounted on the plate 106 and spring-urged so that a screw which it carries engages one of the holes 116. By withdrawing the screw, the record card can be located independently of the holes 116.

Title: Method and apparatus for supplying power to a load
IPC: H02P25/04
Filed: 1972-02-02
Abstract: 1415656 Control systems for consuming apparatus; such as AC motors GEC-ELLIOTT AUTOMATION Ltd 2 Feb 1973 [2 Feb 1972] 4842/72 Headings H2H and H2J A system for supplying power to a load 1 from an A.C. source 2, 3 comprises a triac T1 which is controlled so as to provide at least two power pulses in each half cycle of the A.C. supply thereby suppressing certain of the harmonics which appear in the voltage applied to the load. A firing control circuit 4 produces a gating pulse which is applied to the gate of the triac T1 to render it conductive to produce of current pulse in the load 1 which may be a capacitor start split-phase induction motor. At the same . time a capacitor C1 charges by way of the triac T1 and a resistor R1. A further pulse from the circuit 4 renders a second triac T2 conductive whereupon the capacitor Cl commutates the triac T1 to its non-conductive state to end the current pulse in the load 1. The point X now rises to a voltage determined by a clamp circuit comprising a diode bridge and a capacitor C2 which enables the capacitor C1 to recharge to a polarity opposite to its original charge. Later in the half cycle a second pulse is applied to the gate of triac T1 to render it conductive and initiate a second current pulse in the load 1 and at the same time the capacitor C1 commutates triac T2 off. The second pulse in the load may terminate at the end of the half cycle of the A.C. supply or it may be terminated by forced commutation. As shown in Fig. 3, if the two load current pulses are of equal width and sym-  metrically disposed in the half cycle the third harmonic associated with the pulses cancel. If more than two current pulses are formed in a half cycle other harmonics than the third are suppressed. The amplitude of the fundamental component of the load voltage may be varied by control of the pulse width.

Filed: 1961-02-10
Abstract: 1,017,282. Disc brakes. H. S. BRADLEY, and K. BRADLEY. Feb. 5, 1962 [Feb. 10, 1961; May 3, 1961], Nos. 4973/61 and 16971/61. Heading F2E. A disc brake has each pad 14 freely slidable, towards and away from the disc (not shown), in a hole 13 in a housing 11, whereby lateral forces due to the engagement of the pad with the rotating disc will be transmitted directly from the pads to the housing, and lever mechanism 18, 20 is provided for moving the pads towards and away from the disc. As shown, a pair of pads 14 extend through aligned bores 13 in housing 11 which is formed with cooling fins 43. A pair of sheet metal hook members are secured in recesses 16 in the outer side of each pad 14 and engage pins 23 provided on levers 18. The latter are pivotally connected at 19 to two links 20 disposed in a horizontal groove 21 of the housing and are provided at one end with part spherical bosses 24 which each engage with a depression 25 in the centre of a pressure disc 17 disposed over the outer side of each pad 14. The levers are formed at the other ends with steel balls 27 which engage the sides of a rotary wedge 30 mounted about an axle 29 and having a series of V-shaped teeth 33 about part of its periphery. A lever 28 mounted about the axle 29 and provided with a pivoted pawl 34 engaging teeth 33 when turned in one direction causes the wedge to rotate and move the ends 26 of the levers 18 apart to apply the brake. A spring 41, the legs of which are inserted in holes 42 maintains the balls 27 in engagement with the wedge 30 and effects withdrawal of the pads. A second pawl 35 is carried by a plate 36 rotatable mounted about axle 29 and engages the teeth 33 of the wedge. Normally, the pawl 35 and plate 36 will move with the wedge 30 but if the movement of the latter is greater than the limit of movement of the lug 37 in the slot 38 (Fig. 3, not shown), of the housing the pawl 35 will ride over the teeth 33 so that on the return movement when the lug 37 reaches the other end of its slot 38 movement of the plate and the wedge is arrested. The lever 28 can move beyond this point if it has not reached the end of its stroke and its pawl 34 will ride over the teeth 33. The lever 28 can be actuated by rods, cables or hydraulically.

Filed: 1962-02-13
Abstract: 929,480. Laminating glass sheets. LIBBEY-OWENS-FORD GLASS CO. Feb. 13, 1962, No. 5423/62. Class 140. [Also in Group XXIII] To invert a glass sheet travelling on a conveyer in a substantially horizontal position, the leading edge of the sheet is intercepted and raised upwardly about the trailing edge as the trailing edge moves onwardly and in the raised position, the leading edge is engaged and the sheet lowered in inverted position as the trailing edge continues to move forwardly. As shown, pairs of sheets A, B on endless conveyer belts 20 supported on slats 19 are passed under a spray booth 11, where they are sprayed with a parting material, under the inverting mechanism 12, 13, where the first sheet A is inverted to lie on top of the second sheet B, and thence to an aligning station 14 which aligns the sheets ready for passing to a bending mould. At the edgelifting station 12, a pair of adjustable flexible straps 34 with lateral fingers 35 are mounted on legs 32 extending downwardly from brackets 29 mounted adjustably on a cross-member 25 between uprights 24, the lower part of legs 32 acting as stops for the straps 34. The straps 34 are adjusted so that the fingers 35 lie below the belts 20 and are engaged by the leading edge of sheet A which pivots upwardly to the vertical position. As the straps 34 are freed from the sheet A, they swing down against stop legs 32, clearing sheet B and remaining in position to raise the next sheet A. In the raised position of sheet A, at station 13, the leading edge is engaged by sets of rollers 53 on a pair of shafts 52 mounted on downwardly bent portions 51 of arms 48 pivotally and adjustably mounted on a pintle 46 and with counterweights 54. Pintle 46 is mounted adjustably by arms 43 on a cross-member 39 between uprights 17. The arms 48 are maintained horizontal by engagement of counterweight 54 with stop-members 57 and, as the arms pivot downwardly with sheet A, movement is limited by a cross-member 50 engaging a stop 56 so that the sheet A slides off the rollers and falls the short distance on to sheet B, cushioned by the air between. At the aligning station 14, rollers 64 to engage sheet A are mounted on lever 62 pivoted at 63 and held by springs 68 against a stop member 70. Sheet A is held thereby until aligned with sheet B, when their combined force overcomes the springs 68 and lever 62 pivots out of the way of the aligned sheets.

Title: Improvements in asphalt emulsions for the treatment of coal and method of preparing the same
IPC: C10L9/10
Filed: 1948-02-24
Abstract: In the production of an asphaltic coal coating substance (see Group XII), a colloidal emulsion is formed by running through a colloid mill a quantity of previously blown asphalt and an equal quantity of a solution consisting of water, "Vinsol" (Registered Trade Mark) bentonite clay, "tall oil" and caustic soda. "Vinsol" is a resin obtained by extraction of pine wood chips with a coal-tar hydrocarbon, whilst "tall oil" is a resinous, fatty by-product of the manufacture of paper pulp from resin bearing woods by the "sulphate" process.  The selected asphalt is heated and blown for about 8 hours, its penetration being thereby reduced from 80-100 to 26-30, and its melting point rising from 140-180 DEG  F. to 210-260 DEG  F.  It is then heated to about 300 DEG  F. and run, with an equal quantity of an aqueous solution consisting of 95 per cent water, 3.0 per cent "Vinsol," 1.4 per cent bentonite clay, 0.10 per cent "tall oil" and 0.46 per cent caustic soda into a colloid mill.  The resulting colloidal suspension is run to storage.

Abstract: 972,416. Feeding sheets. J. BOBST & FILS S.A. Feb. 11, 1963 [Feb. 12, 1962], No. 5573/63. Heading B6B. In a cutting, creasing &c. platen press wherein a lower part 2 is reciprocated vertically towards and away from a fixed part 1, and sheets are fed between the parts from a sheet-seizing position 3<SP>1</SP> to a working position 3<SP>11</SP> by gripper bars 3 on a pair of endless chains 4, the bars are registered at each position by a pair of stops 6<SP>1</SP>, 6<SP>11</SP> which can be oscillated about their own pivots, can be raised and lowered bodily, and can be reciprocated bodily in the direction of movement of the chains, these movements being performed in synchronism with the movements of the platen part 2. The arrangement is such that the stops 6<SP>1</SP> or 611 are raised into the path of the appropriate bar 3, moved towards the bar, stopped, then moved in the same direction as the bar so that when the bar engages the stops they are both decelerating, until the sheet and bar are brought into registered position. As described, each stop 6<SP>11</SP> is oscillatable about a pivot 46, Fig. 4, on a bar 12, by a link 40 and a member 41 pivoted at 43 also on the bar 12: in the register position shown, the pivots of the link 40 and the pivot 43 are in a straight line, and the stop 6<SP>11</SP> is therefore rigid. The bar 12 is reciprocated horizontally in a frame 10 by means of a camoperated rod 16, and linkages 17, 18, and the stop 6<SP>11</SP> is oscillated by a cam-operated link 26. Further, the frame 10 itself is reciprocated vertically by cam-operated links 21, 22 in a fixed framework 11. The top 10<SP>1</SP> of the frame 10 has members 48, 49 pivoted thereto to act as chain guides, and the chains 4 and gripper bar 3 are raised by these parts when the frame 10 is raised. The movement of the bar 12 to the left is limited by a screw-stop 13. A pair of stops 6<SP>1</SP> register a gripper bar at position 3<SP>1</SP>, and these are operated by mechanism similar to that for the stops 6<SP>11</SP>.

Title: Improvements in and relating to gas-fired circulatory water heaters
IPC: F24D19/10
Filed: 1966-02-09
Abstract: 1,141,006. Hot water boilers; central heating systems. JUNKERS & CO. G.m.b.H. 9 Feb., 1966 [9 Feb., 1965 (2)], No. 5579/66. Headings F4A and F4U. The flow and return lines 13, 15 respectively of a circulating water heater 10 fired by a gas burner 11, are interconnected by a cross connection line 32 leading into a Venturi intake device 30 in the return line 15. The Venturi intake device 30 is bridged by short circuit pipe 34 containing a three way valve 351 controlled by a thermostat 36 downstream in the return line 15. A further cross connection line 40 connects the short circuit line 34 at the three way valve 351 with the flow line 13. In operation, when a room thermostat (not shown) calls for heat to start circulating pump 12 and light the burner 11, the water from pump 12 flows in parallel both through section 151 of return line 15 and through section 341 of short circuit line 34. The water flow through Venturi intake device 30 includes a flow of heated water from flow line 13 along cross connection line 32 past non-return valve 33 whereby the temperature of the water flowing to the heater 10 is increased to avoid condensation of combustion products from the burner 11 thereon. The water flow through pipe section 341 is diverted through the further cross connection line 40 to the flow line 13, downstream of the take off point of the first cross connection line 32, whereby an excessive temperature difference across the radiators 14 may be avoided throughout the start up period. When the water temperature at the inlet to the heater 10, as measured by thermostat 36, has achieved a sufficient value to avoid condensation of the combustion products, valve 351 is actuated to close the further cross connection line 40 and open line 34, whereby due to the great pressure drop in Venturi intake device 30, practically all the flow from circulating pump 12 passes through the short circuit line 34 and the flow from the flow line 13 through the first cross connection line 32 ceases. High and low pressure tappings 38, 39 are taken from section 151 of return pipe 15 and pipe 32 respectively, to either side of a diaphragm 19 in a pressure box 18, and used to operate a gate valve 24 in the gas supply line 25 in the event of water deficiency.
