Title: Improvements in biscuit and like sandwich making machines
IPC: A21C15/02
Filed: 1957-04-29
Abstract: 808,720. Biscuit sandwich-making machines. OAKES CORPORATION, E. T. April 29,1957 [May 18, 1956], No. 13576/57. Class 78 (1). [Also in Group VI] Cakes, biscuits or the like are fed from a magazine alternately on to upper and lower conveyers those on the lower conveyer receiving filling from a device after which one from the upper conveyer is superimposed on each. Magazine A has a series of troughs 10 forming hoppers for receiving horizontal stacks of cakes C either from an operator or direct from an oven conveyer. The bottoms of the troughs are formed by a continuously driven conveyer belt 11. A plate 12 mounted on a frame F forms the back of a feed slot 13 and engages the end of the stack of biscuits as they pass over a plate 39 and beneath a guide plate 40. A reciprocating bar 16 guided by ribs 41 which engage grooves 42, 42a in plate 12 is driven by a crank 17 and connecting rod 18 and moves up and down in slot 13 alternately pushing a row of cakes up to a conveyer belt 14 and down to a conveyer belt 15. The cakes are guided on to conveyer 14 by a plate 19 secured to guide 40. The cakes moving downwardly are received in a shoot 45 consisting of a plate 46 with partition strips 47 secured to plate 39 and resilient strips 48 to guide the cakes into engagement with the strips 47. The cakes are pushed through shoot 45 and on to conveyer 15 by fingers 20a carried on plates 20 secured to the links of chains 21 which fingers pass between strips 47 and 48. Chains 21 are mounted on sprockets 56, 57 fixed on shafts 58, 59. The cakes are thus placed correctly spaced on conveyer 15 which carries them under a depositor 22. Conveyer 14 is supported on a fixed bar 43 at the receiving end and a roller 60 at its other end, the top flight being supported by a plate 44 and the lower flight passing round a driven roller 61 and a series of guide rollers. The cakes are deposited in rows from conveyer 14 to a shoot 27 carried on a cross-bar extending between the sides of frame F where they are aligned with the cakes on conveyer 15 by guide plates similar to strips 47, 48. Elements 25 have fingers 29 which extend between guide plates 63 and are spaced to correspond with the spacing of the cakes on conveyer 15 so that the cakes from conveyer 14 are deposited on the topped cakes on conveyer 15. Elements 25 are carried on a conveyer 26 consisting of a pair of chains 66 passing over spaced sprockets 68 supported on shafts 70, 71. The sandwiches are pressed together by a roller 75 mounted on an adjustable lever 76. Specification 700,962, [Group VI], is referred to.

Patent GB-1581561-A (GB)
Title: Magnetic printing process
IPC: D06P5/00
Filed: 1977-03-31
Abstract: For the magnetic printing or transfer of characters, a latent magnetic image is firstly produced on a ferromagnetic material which is printed onto an electrically conducting support. The magnetic image is then decorated with a ferromagnetic toner. The toner contains a ferromagnetic component, selectively at least one dyestuff or at least one chemical treatment agent and a resin which contains the ferromagnetic component and the selected component in a virtually completely encapsulated manner. The magnetic image is developed by means of the said toner. The image is then transferred to a substrate, it being possible for the transfer to take place by means of a mechanical, electrical or magnetic process. The character can be transferred either directly or via an intermediate substrate. The device for carrying out the printing operation described contains above all a magnetic printing element (1) which produces a ferromagnetic material which is mounted on an electrically conducting support. The ferromagnetic material preferably contains needle-shaped CrO2. The device also contains means (13) for supplying the toner with the ferromagnetic material, means (20) for transferring the developed image to a substrate, and means (21) for removing the ferromagnetic components from the image on the substrate, and means (24) for the permanent fixing of the equipment on the printed substrate. An important application of the process relates to multi-colour printing on textiles. The new process has ecological advantages compared to conventional methods. <IMAGE>

Title: Improvements in the production of solidified carbondioxide
IPC: C01B32/55
Filed: 1931-05-08
Abstract: Solidified carbon dioxide is produced by burning petroleum products, cleaning, purifying and cooling the combustion products, dissolving the carbon dioxide in a solution, separating the carbon dioxide from the solution, liquefying it and then allowing it to expand to produce snow.  A suitable apparatus for carrying out the process comprises a furnace 1 in which the petroleum product, pretreated by an ozonizer 3, is burnt, and from which the product of combustion is drawn by an impeller 5 to pass through scrubbers 6 and a purifier 9 wherein it is treated with a liquid such as sodium bicarbonate solution which is circulated through a cooler 16.  The gas is then drawn through a cooler 19 and passes to an absorbing tower 24 wherein it is treated with liquid which absorbs carbon dioxide such as potassium carbonate solution.  The liquid from the base of the tower is transferred by a pump 28 to tanks 29, 31 and thence through the coils of a heater 33 to a sprayer 35 by which it is <PICT:0378490/III/1> discharged over steam-heated coils 36.  The evolved carbon dioxide passes through a cooler 40 to a gas holder 42.  The hot liquid from the coils is pumped back through coils in the tank 29 and a cooler 49 to the absorbing tower 24.  Gas is pumped from the gas holder 42, through a cooler 59 and scrubbers 61, to compressors 62 and thence through a cooler 64 to a container 66 for the liquefied carbon dioxide which passes thence through coils 68 to a spraying chamber 72 wherein pressure is released so that solid carbon dioxide is produced.  The gas evolved in the release chamber is returned to the gas holder.

Title: Improvements in or relating to repeater circuits for phase modulated electric pulses
IPC: H04J3/00
Filed: 1948-05-21
Abstract: 655,852. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. May 21, 1948, No. 13790. Convention date, July 2, 1947. [Class 40 (v)] A repeater for a train of phase modulated pulses comprises means for storing energy in an energy storage device proportional to the modulation of each pulse to provide a stepped wave which is used for the modulation of a train of output pulses. The invention enables signals from a branch station to be inserted in correct phase corresponding to a spare channel in a multiplex pulse train which is being relayed by the repeater station. Fig. 3 shows a repeater station at which incoming time modulated pulses from a branch station are applied to receiver 17 which supplies a corresponding train of width modulated pulses 18. The pulses 18 are applied to render valve 19 conducting so that during each pulse condenser 21 is charged from a constant current source 20. A differentiating circuit 27 is arranged to supply a positive pulse to the grid of valve 26 representing the leading edge of each of the pulses 18. Valve 26 is thus rendered conducting to discharge condenser 21 at the instant of the leading edge of each pulse. The output from condenser 21 is in the form of rectangular pulses 22, the amplitudes of which correspond to the time modulation of the original input pulses. Pulses 22 are applied to pulse time position modulator 23 to modulate pulses generated in the correct phase for interspersing with other trains of time modulated pulses arriving over line 24. The multiplex pulse train is then applied to radio transmitter 25.

Title: Improvements in and relating to cathode ray signal portraying apparatus
IPC: H04N3/34
Filed: 1947-05-23
Abstract: 645,002. Cathode - ray oscillographs. BRITISH THOMSON-HOUSTON CO., Ltd. May 23, 1947, No. 13877. Convention date, Dec. 20, 1943. [Class 37] A circular trace is produced by coupling the horizontal and vertical deflecting means of a cathode-ray oscillograph to the primary and secondary windings of a transformer, both these windings being tuned to the supply frequency. Equal sinusoidal voltages 90 degrees out of phase are obtained from a generator 15 supplying an amplifier 16, the output circuit of which includes the primary winding of a transformer 20. The primary and secondary windings of the transformer 20 are tuned to resonance at the frequency of the impressed voltage by variable condensers 24, 25. A variable resistor 26 enables the current in the secondary winding to be adjusted. The primary and secondary windings of the transformer 20 are coupled to tuned circuits 27, 28 through link couplings including a low-impedance four-conductor transmission line 29 and windings 34, 35, 36, 37 having relatively few turns, so that there is a step-down of voltage from the primary and secondary windings to the link couplings and a step-up of voltage from the couplings to the inductances 30, 31 of the tuned circuits 27, 28 which are connected to the horizontal and vertical deflecting plates 13, 14, 11, 12 of the oscillograph 10. Since the distributed capacities of the conductors of the transmission line 39 are connected across a low impedance circuit, this capacity has a negligible effect on the phase of the voltages across the tuned circuits. The diameter of the circular trace may be varied by means of a voltage dividing resistor 39 by means of which the voltage on the screen grid of the amplifier valve 16 is adjusted.

Patent GB-446137-A (GB)
Title: Improvements in fractional distillation
IPC: B01D3/14
Filed: 1935-05-13
Abstract: <PICT:0446137/III/1> Oils are fractionally distilled by passing them through a heating zone into a fractionating tower at a point between fractionating trays, the vapours being separated into fractions which are removed from the top and sides of the column, while reflux collecting at the bottom of the column is removed separately, and the process is characterized in that a fraction of higher boiling point than the side stream fractions is collected medially in the column, mixed with the crude and recycled through the heating zone.  Crude oil is pumped by a pump 32 through heat-exchangers 30, 65, 90, 102 and line 107 to heating coils 11, 12 and thence through a line 13 into a fractionating tower 14 in which vaporization is assisted by steam heated in a coil 16.  Light fractions withdrawn from the top of the tower are cooled and separated from gases and water in a receiver 22.  A supply of reflux controlled by a thermostat 37 is obtained by withdrawing fractions through lines 27, 28 cooling these in heat-exchangers 30, 33 and returning them through a line 35.  Side streams are withdrawn through lines 38, 39 to a stripping tower 41 supplied with steam through a line 19 the vapours formed being returned through a line 42.  The unvaporized fractions are withdrawn through a line 53 and passed through a second heating coil 57, 58 into a further column 59 from which vapours and side streams are similarly withdrawn for condensation &c., through lines 64, 86, while unvaporized residues are led off through a line 99.  The fractionation in this tower is improved by leading off side streams through lines 116, 117 and passing these through lines 120, 122 into the first fractionating tower 14 on to the lower-most trays 15<1> or directly into the bottom of the tower so that they mix with the unvaporized fractions and with them are fed to the coils 55, 56.  In a modification only a single heating coil and fractionating tower is employed and the fraction taken off at the middle of the tower is mixed with the crude oil in a container before being recycled through the heating coil.
