Title: Improvements relating to the stacking of biscuits
Inventor: HARDING GEORGE EDWIN
IPC: A21C15/00
Filed: 1962-10-18
Abstract: 1,042,884. Sheet stacking apparatus. BAKER PERKINS Ltd. Oct. 14, 1963 [Oct. 18, 1962], No. 39491/62. Heading B6H. [Also in Division B8] An apparatus for forming a horizontal stack of sheets 21, each supported against the next at an angle to the vertical, comprises a horizontal conveyer 1 having a pair of endless parallel spaced wires or ropes 15 and a receiving endless belt conveyer 8 having its horizontal run lying between the ropes 15 and just below them. The ropes 15 are driven around pulleys 3, 4, 5, 6 by a pulley 2 and the upper runs are supported by further pulleys 16. The belt 8 is driven around pulleys 10, 11, 12, 13 by pulley 9. The conveyer system 8 is displaced to the right of the rope system 15 as seen in Fig. 1. Sheets 23 of basically circular form, delivered in spaced relation to the parallel ropes 15 are centralized thereon by guides 24, and are conveyed to a manually created stack of sheets 21 on the platform 20 of a packing machine 22. As the leading edge of the sheet 23 engages the last sheet in the stack, it slides up the inclined surface until its trailing edge dips below the surface of the ropes 15 and engages the belt 8 which then takes the weight. Air coolers 29 may be provided above or below the line of sheets. According to the relative velocities of the conveyers 1 and 8 or due to stoppages &c., the stack of sheets 21 may either increase in length to operate a switch 30, which causes a diversion of the sheet feed, or decrease in length to operate a switch 31 which stops the conveyer 8. The conveyer 8 may be replaced by a stationary receiving surface, whereupon batches of sheets are stacked and subsequently removed. The two wires or ropes 15 may be replaced by a belt with a pair of supporting ridges or by two discs or by a pair of vibrating rods.
Patent GB-1045210-A (GB)
Title: Dimerization of propylene
IPC: C07C2/18
Filed: 1964-09-30
Abstract: The dimerization of propylene is effected in an aqueous reaction medium containing an acidic catalyst and in the presence of a propylene solvent miscible with the aqueous reaction mixture and a solvent for propylene dimers immiscible with the aqueous reaction mixture. Preferred propylene solvent is isopropanol, the presence of which minimises its production; others are ethanol, propanol, butanols, ethylene glycol, acetone and methyl ethyl ketone. Preferred dimer solvent is higher propylene polymers produced in the process, their presence also minimising their production; others are isopropyl ether, n-propyl ether, hexanol, kerosene, tetralin and decalin.  The catalyst may be sulphuric, phosphoric, benzene sulphonic or toluene sulphonic acid or a cation exchange resin.  Reaction is effected at 100-350 DEG  C. and 500-5000 p.s.i.  The reaction effluent is separated into two layers; the lower aqueous layer is recycled and the upper layer distilled to recover dimer and dimer solvent which is recycled.

Patent GB-400582-A (GB)
Abstract: 400,582. Seat-operated taximeters. DEHN, F. B., 103, Kingsway, London.- (Checker Cab Manufacturing Corporation; Kalamazoo, Michigan, U.S.A.) March 15, 1932, No. 7703. [Class 106 (iii).] A taximeter is put into operative condition through seat-operated electromagnetic mechanism. The shaft 10 of a taximeter controlling the condition of the registering mechanism has fixed to it a disc 12 and the flag 11. A pawl 38 pivoted at 40 on the pawl 41 normally engages a notch 39 in the disc to keep the shaft in the inoperative position. On a passenger taking his seat on the cushion 2 the contacts 7 are made to energize the electromagnet 8 to cause the plunger 13 to rotate a lever 15 secured to a shaft 16. The shaft 16 carries a cam which engages a lever 25 to rotate it about its pivot 26 and thus pull down the link 27 to rotate the bell-crank lever 28 pivoted at 29, the arm 50 of which partially raises the pawl 41 pivoted at 42 to cause the disc 12 to rotate through one-eighth of a revolution in a clockwise direction under the action of a spring 36 connected at one end 37 to the disc 12 and at the other to a pin 35 on a cam member 32 loosely mounted on the shaft 10 and with a notch 44 which engages the pawl 41. The pin 35 extends through a slot 31 in the disc 12 which also has a slot 30 with which engages a pin 34 on the cam member to limit the initial rotation of the disc 12. As the disc 12 rotates with the pawl 38 still engaging the notch 39, the pawl 41 is raised out of engagement with the notch 44 by toggle action to allow the cam follower 46 on the spring-controlled lever 47 pivoted at 48 to engage an additional cam surface 33 on the member 32 and force the member 32 and disc 12 one-quarter turn to set the fare-registering parts of the meter into operative position. The disc 12 is retained in the operative position by a lever 53, normally held away from the disc by a pin 54 on it engaging with the bell crank 28, spring pulled into engagement with the notch 39, a lever 56 engaging with a notch 57 in the disc to prevent backward movement. Backward movement of the disc is prevented in the inoperative position by the lever 56 engaging a notch 57<1>. On a passenger vacating his seat the switches 6, acting in the opposite manner to the switches 7, are closed to energize the electromagnet 9 to force out the spring returned plunger 59 to rotate the bellcrank lever 23 to allow the lever 15, shaft 16, lever 25, link 27, and bell crank 28 to return to their normal positions under the action of the spring 64. At the same time the switch 20 is broken to de-energize the electromagnet 9. The bell-crank lever 28 in returning to normal engages the pin 54 to move the lever 53 out of engagement with the notch 39. This allows manual operation of the plug 11 to complete the rotation of the shaft 10 and restore the mechanism to normal.

Patent GB-1098265-A (GB)
Title: Method and apparatus for chromatographic analysis
IPC: C07C7/148
Filed: 1965-09-28
Abstract: Fluid mixtures are chromatographically analysed by conveying a sample of the fluid in a first carrier gas stream to a chromatographic separation zone containing an adsorbent, e.g. a molecular sieve or alumina, which completely adsorbs both the sample and the carrier gas, terminating the admission of sample and gas to the zone before the adsorbent is fully loaded, then eluting the sample from the zone using a second carrier gas which is less readily adsorbed than the first, and measuring the effluent with a chromatographic detector. The process is particularly applicable to the detection of total N in hydrocarbon streams; thus liquid samples of hydrocarbon feed from stream 1 are injected into stream 3 of CO2 by valve 9, oxidized over CuO in furnace 12 and then accumulated in a column of a molecular sieve material 20 after passage through Cu furnace 16 where oxides of N produced from the N-compounds in the previous stage are reduced to N2.  After say 20 samples valves 13 and 15 are switched and H2 carrier gas is used to elute the accumulated samples from the column for detection at 24.  The CuO is regenerated by oxygen from line 36. The system may also be used for the detection of trace S in the hydrocarbon stream.  The various valves of the system are automatically controlled by sequence controller 31.  Other specified carrier gases include steam instead of the CO2, and He and A instead of the H2.  In a variant, instead of a single column 20, two columns in series are used, in the first of which the sample is adsorbed, and in the second of which the components are separated.

Abstract: 1,023,487. Electric selective signalling. GENERAL PRECISION Inc. Oct. 12, 1964 [Nov. 15, 1963], No. 41504/64. Heading G4H. In a position digitizer, a capacitively-sensed member comprises two conductive segments insulated from each other, an A.C. generator being electrically coupled to the segments for providing a varying electrostatic field surrounding the segments, the field having a fixed zero potential level at a line between said segments. In a first embodiment (Figs. 2, 4, not shown), A.C. signals in anti-phase are applied to two mutually-insulated patterns from opposite ends of the centre-earthed secondary of a transformer. The patterns alone form four binary tracks sensed capacitively by respective sensing elements. The phase-significant signal from each of these latter elements passes through an emitter follower to be combined in an AND gate with the signal from one end of the transformer secondary (as a reference phase), the 1 gate output being rectified, filtered (to leave just the envelope) and squared up (in a Schmitt trigger). Figures 5-7 (not shown) show an embodiment using two discs, one bearing the binary tracks and the other the sensing elements, there being lead and lag sensing elements for each binary order except the lowest, for V-scan operation. Figs. 8 and 9 (not shown) show an embodiment having a single track for two binary orders, the sensing elements being such that the ANDing with a reference phase can be dispensed with, one segment of the least significant track spanning two sensing plates of the corresponding sensing element. By placing the earth connection to the transformer secondary non-centrally, a signal of one phase in a sensing element may be made of smaller amplitude than one of the other phase and by having the Schmitt trigger threshold between the two amplitudes, the AND gate, rectifier and filter of the first embodiment are dispensed with (Figs. 10, 11, not shown).
