Title: Improvements in or relating to devices for separating adjacent articles
IPC: B65B23/14
Filed: 1961-01-12
Abstract: 912,449. Endless conveyers. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. Jan. 12, 1961 [Dec. 2, 1960], No. 1283/61. Class 78 (1). [Also in Group XVII] In apparatus for separating biscuits into individual groups, the biscuits are fed by a conveyer belt 2 across a fixed plate 3 and on to a vertically displaceable table 4. A member 11 for separating the biscuits is pivoted at 10 on a vertically slidable member 9 and is normally maintained vertical by pins 14 which engage a leaf-spring 13. A support 8 in which the member 9 slides is carried by a horizontally-slidable member 7. When the table 4 is completely filled with biscuits, a presser 18 descends on the biscuits on the plate 3 and holds them fast. Simultaneously a stop-member 5 is withdrawn beyond the end 4a of the table 4 and the separating member 11, when the member 9 descends, is able to move between two biscuits, Fig. 2. As the separating member 11 approaches its lowest position, a cam follower 15 on the upper part of the member 11 engages a cam track 16 provided on the support 8 and the member 11 pivots slightly before engaging an abutment 17 on the member 9. The horizontal slide 7 together with the member 11 then moves in the feed direction "A" and all the biscuits of the separated group are pushed on to the table 4 which then descends, Fig. 3, to a position from which the biscuits are fed for further processing. The stop 5 then moves left to the position shown in Fig. 3, the member 11 and the presser 18 are raised and biscuits are again moved by the belt 2 on to the table 4 which has meanwhile returned to it upper position. The stop 5 is pushed to the position shown in Fig. 1 and a new cycle begins with the lowering of the presser 18.

IPC: A63F9/14
Filed: 1916-01-27
Abstract: 101,647. Clorius, O. T., and Clorius, A. V. Jan. 27, 1916. Race games, mechanical.-In an appliance for playing a race game, model horses a, Figs. 1 and 4, are drawn along tracks by means of strings c each actuated by a separate handle 6 in such a manner that, if the speed of the handle exceeds a pre-determined limit, the driving-mechanism is temporarily disconnected from the horse. Each string c passes round pulleys f, k and carries at one end a weight l, the other end being attached to a drum g driven by the actuating-handle 6 through a shaft m. The drum g, Fig. 2, is loose on a shaft n, but is retained in driving engagement therewith by means of a pin p<1> secured to the shaft, a conical pin r on the drum, and the end pressure of a loose pulley s influenced by a spring 7. The pulley s is rotated continuously by means of a motor. If the speed of the handle 6 exceeds a predetermined limit, the drum y, together with the pulley s, is pressed towards the right, owing to the conical shape of the pin r, and an internal screw-thread in the boss of the pulley s engages a screw-thread on the shaft n. The pulleys s is then drawn farther to the right, and the drum g is disconnected from the driving-shaft. The horse a then stops or is moved backward by the counterweight l, until the driving-mechanism is again coupled up by reducing the speed of the handle 6. The string c is connected to the horse by means of a pulley e, so that the horse is rotated to face in the direction of its movement. The handles 6 are simultaneously connected or disconnected with the shafts n by means of clutches o controlled by a common cam shaft p.

Abstract: 1,020,594. Large capacity evaporators. CHICAGO BRIDGE & IRON CO. Jan. 11, 1963 [April 11, 1962], No. 1312/63. Heading BIB. A large evaporator 10, e.g. of a capacity of 50,000-2,000,000 gallons, for crystallizing solutions by adiabatic evaporation under reduced pressure, comprises a hemispherical top portion 11 welded to a bottom conical portion 12, the top portion being provided with a vapour outlet, and the bottom portion being provided with a feed inlet 13 just below the surface of the liquid which is maintained at the point of maximum cross-section. The feed inlet is preferably aligned to deliver the feed in a non-radial direction. Bottom portion 12 is also provided with a slurry outlet 18, a drain outlet, and a recirculation system for the solution in the evaporator, comprising outlet 14, pump 15, heat exchanger 15, and pipe 17. Solution entering evaporator 10 via inlet 13 undergoes flash evaporation and becomes cooled. Any crystals that are formed fall to the bottom of the evaporator and are removed as a slurry from outlet 18. The cooled mother liquor is withdrawn via outlet 14 and is recirculated to mix with the inlet feed, being heated in heat exchanger 16 during the recirculation. The vapour formed in evaporator 10 passes via the entrainment separator 19 into the heat exchanger 22 where it heats the mother liquor being recirculated in a second evaporator 20 maintained at a pressure below the pressure in evaporator 10 by the action of steam jet ejector 30. The construction and operation of evaporator 20 are similar to that of evaporator 10. An internal baffle 120, Fig. 4 (not shown), may be provided inside the bottom section 112 of the evaporator to divide it into crystallization zone 115 and thickening zone 119 the latter having an exposed surface area of 5-50% of the total exposed surface area. In operation, the crystal slurry formed in zone 115 is withdrawn from outlet 117 and is passed via line 118 into zone 119. Thickening of the slurry occurs in zone 119, the thickened slurry being removed via outlet 123 and the clarified mother liquor being removed via overflow 122. Also described is an evaporator wherein the internal baffle is provided with an aperture at its lowest point so that clarification of the mother liquor is achieved without external recirculation of the crystal slurry. These evaporators can be used in multiple effect for separating mixtures of sodium borate and sodium sulphate by fractional crystallization (see Division C1).

Filed: 1971-01-12
Abstract: 1339919 Separating particles from gases BAYER AG 12 Jan 1971 [4 Feb 1970] 4388/71 Heading B1R Particles, e.g. metal oxides, are separated from hot gas streams in which the oxide is suspended by passage downward through pipe 1 into conical section 9. Cold gas supplied through pipe 4 passes through porous-walled tube 5 into the hot stream, thereby cooling it. The gas stream is further cooled by contact with cold aqueous liquid which enters by tangential pipe 7 and passes downwards as a rotating film over the surface of conical section 9. The liquid/solids/gas mixture then passes to pipe 11 where it meets a spray of liquid introduced downwardly by non-radially positioned nozzles 12. All the oxides in the gas stream are removed in suspension in the wash liquid leaving the apparatus, some of the suspension being returned to pipe 7 and nozzles 12. The apparatus is of particular application to the TiO 2 -containing stream from a reactor in which TiCl 4  is reacted with an oxygen-containing gas.

Title: Improvements in and connected with protective relays for train lighting and like installations
IPC: H02J7/22
Filed: 1941-02-07
Abstract: 547,008. Charging batteries; electromagnetic switches. STONE & CO., Ltd., J., and NIXON, L. R. Feb. 7, 1941, No. 1674. [Class 38 (iv)] [Also in Group XXXVII] In a train lighting or like system using a self regulating variable speed generator and a battery an overcharge relay reduces the dynamooutput at a given voltage and an over-voltage relay further reduces or stops the output. Preferably the two are side-by-side in a common casing and the latter, when operating, operates the former mechanically and is itself held or latched in the operated condition, both being thereby held in operation until manually reset, as by a mechanically acting push-button projecting from the case. The arrangement may operate a visual indicator 18. Each relay comprises a contact arm 2a carried by a member 3a carrying an armature co-operating with a permanent magnet 8 to hold the contacts closed notwithstanding vibration. The pivot 4 carries also a clapper armature 5a co-operating with the core C<SP>1</SP> of an electromagnet to actuate the member 3a through a spring 10 and overcome the permanent magnet to open the contacts. The clapper of the overvoltage relay is attached to a member 14 pivoted on the same axis and having a projection 15 overlapping the contact carrying elements of the overcharge relay to cause the desired operation thereof. When operated the overvoltage relay may be held by permanent magnetism of its core C<SP>1</SP> or by a mechanical latch. Two push buttons engage parts of the member 14 in opposite sides of the axis whereby it may be operated and reset manually. One push-button may be arranged to release the latch when resetting. The Specification describes relay arrangements (1) to open respectively two field circuits of three-brush dynamos of two kinds and (2) respectively to insert resistance in and to open the field circuit of a Rosenburg generator. The overcharge relay may have its calibration altered when the load circuit is switched on by the removal of a resistance in series with its winding or by connecting up an additional solenoid winding.

Title: Sheet feeding apparatus
IPC: B65H3/08
Filed: 1956-01-18
Abstract: 785,414. Feeding metal sheets. AETNASTANDARD ENGINEERING CO. Jan. 18, 1956 [April 20, 1955], No. 1695/56. Class 100(1) Metal sheets S are separated from a pile P in a support 4 by an oscillating sucker 25<SP>1</SP> until they contact rotating magnetic rolls 7, 9, whereupon suction ceases, and the sheets are fed upwardly by the rolls between guides 14, 15 to pairs of feed-off rolls 10, 11 and 12, 13 for movement to a tinning, galvanizing or other machine. As shown in Fig. 3, there are three piles P, and three pairs of suckers carried by arms 16-21 secured on a single pivot shaft 5, the arms all being attached together by a tierod 22 connected to and oscillated by the rod 29 of a piston in a fixed cylinder 27. The working fluid is allowed to enter the cylinder on either side of the piston under the control of a four-way valve V operable against the action of a return spring by a solenoid M which is energized when a sheet S completes an electric circuit through one of the contactors 87, 89, or 91 on the shaft 8 of the roll 9. Suction to each sucker 25<SP>1</SP> is established through a hose 44, a header pipe 45, hose 48, and pipes 50, 49 connected to a fixed cylinder 51. A piston 52 in this cylinder is secured to a rod 53 having a pin-and-slot connection With a vertical arm 55 keyed on the shaft 5, whereby the piston is moved to the right by the oscillation of the sucker arms 16-21 to produce suction at the suckers 25<SP>1</SP>. An adjustable member 62 on. an extension 55<SP>1</SP> of the arm 55 opens a relief valve 59 to release the sheets S only when the sheets make contact with the magnetic rolls 7, 9. A pin on the arm 55 is adapted to close a reverse limit switch 65 after a sheet is released, but this has no effect on the circuit until a sheet S leaves the rolls 7, 9. The same pin on the arm 55 is also adapted to open a forward limit switch 67 to de-energize the solenoid M and allow the valve V to be returned by the spring to the position shown in Fig. 2. Each sucker 25<SP>1</SP> is formed on a head 25 carried by a tube 24 slidable, against the action of a spring 26, in a bracket 23 secured to the operating arm, such as 16. The spring 26 allows the arm 16 to continue to move after a sheet has been engaged by the sucker, allows time, on the reverse movement of the arm, for suction to build up in the sucker, and compensates for the depletion of sheets in the pile P. The electric circuit described and shown in the Specification includes two transformers to supply current at reduced voltages, and a series of relays and switches, and ensures that (a) the suction separator arms 16-21 will remain retracted until the sheets have left the magnetic rolls 7, 9; (b) even though the main switch and starting button have both been depressed, the apparatus will not function unless there is a supply of low voltage current to energize a starting relay; and (c) prevents rapid vibration of the separator arms in the event of a sheet slipping:from contact with the contactor rings on the magnetic rolls 8, 9.

Abstract: 523,985. Two-part couplings combined with switches. ELECTROLUX, Ltd. Jan. 18. 1939, No. 1783. Convention date, Jan. 18, 1938. [Class 38 (i)] [Also in group XXXVII] A switch housing for mounting on an electrical apparatus carries contact plugs 16 for connection to a supply lead, and has contacts 53 arranged in sockets 54 into which can be inserted blades 15a attached to leads 15 connected to the apparatus. One of the plugs is connected directly to one contact 53 and the other plug 16 and the corresponding contact 53 are connected to a pair of fixed switch contacts 21 arranged side by side and adapted to be connected together by a roller 22 moved by the switch-operating mechanism. This comprises a push-button 36 carrying a pusher rod 47 rocking on pivot 45 and kept central by the spring 43 that restores the push-button. The rod 47 acts on one or the other of inclined surfaces 49, 51 on a rocker 28 to which the roller 22 is connected by a snap action mechanism consisting of a pin 27, slot 26 and spring 29. The roller 22 moves on insulating guides 23.

Title: Signal switching arrangement
IPC: H04B1/74
Filed: 1973-01-15
Abstract: 1384971 Signal switching circuits; RF and IF band circuits NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and NIPPON ELECTRIC CO Ltd 15 Jan 1973 [14 Jan 1972] 1921/73 Headings H3W H3Q and H3P In a signal switching arrangement for selectively connecting one of first and second input terminals A, B, Fig. 1b, to a signal output terminal C comprising a plurality of electromagnetic relays RL1-RL4 having a common operating circuit for their operating coils BL1-RL4 and whose contacts r11-r14 connect the first and second input terminals to the output terminal in first and second states of the relays, each operating coil is connected in series with a corresponding first variable impedance RV1-RV4 and in parallel with a corresponding second variable impedance RV5-RV8 so that the response time of each relay to a change in current in the operating circuit may be adjusted so that during switching the signal output terminal is always connected to at least one signal input terminal. The signal switching arrangement may be used for the radio frequency band circuit and/or intermediate frequency band circuit of a microwave communication system. The response times of the relays RL1-RL4 to energization are controlled by adjusting the variable resistors RV1-RV4 and the response of the relays to release are controlled by resistors RV5-RV8. The relays may be single pole double throw break-beforemake type connected as in Fig. 1b. Assuming the input signal at A is connected via contacts rl1 and rl2 to C, by suitable adjustment of these resistors when the switch S is closed the contacts rl4 and rl3 are first closed to connect the input signal at B also to C as the contacts rl2 and rll are opened to disconnect the signal path between A and C. The same principle is applied for setting the response time of the relays for the disconnection of the power supply as is perfomed in order to restore the state of the signal after switchover. Signal overlap switching can be obtained by adjusting the variable resistors. However increased signal level at the output C then occurs when the two input signals A, B of identical phase occur simultaneously at the output C during the switching operation. In order to avoid this a mercury relay of the bridge, i.e. make-before-break type, is used as e.g. relay RL1 and the response time of the relays to the energization are suitably controlled (Fig. 7, not shown), so as to provide in an equivalent circuit (Fig. 8, not shown), in which level variation of the signal applied to the load (R 0 ) is avoided. The operation of the mercury relay moveable contact in relation to two fixed contacts is disclosed (Figs. 9a-9c, not shown).
