Abstract: 1386610 Vinyl chloride polymer/vinyl or allyl monomer foams EXXON RESEARCH & ENG CO 25 Sept 1972 [21 Oct 1971] 48957/71 Heading C3C A rigid or semirigid self-skinned cellular plastic structure which has a modulus of elasticity of at least 700 Kg/cm.<SP>2</SP>, is heat recoverable (defined in terms of a specified test) and is thermoelastic (i.e. rigid at up to 75‹ C. and elastomeric at higher temperatures) is made by heating a plastisol or pregelified dryblend of a polymer of vinylchloride, polymerizable polyallyl or polyvinyl monomer (the polyallyl monomer being a non-volatile monomer containing ester, amide, epoxy or other groups known to have a solvating and plasticizing action on the vinyl chloride polymer), and a peroxide catalyst, the heating being carried out at 10- 30‹ C. per minute at least up to the temperature at which expansion starts and the reacting mass being free to expand without restraint in at least one direction, the product being a graft polymer. In the plastisol form the vinyl or allyl monomer serves as the plasticizer. The cellular material may also contain another polymer, e.g. a styrene-butadiene-acrylonitrile or -methylacrylate resin, an acrylonitrile-butadiene acrylate resin, an ethylene/vinyl acetate copolymer or a chlorinated polyethylene. The monomer may be divinyl benzene or an allyl acrylate, maleate, fumarate, phthalate or cyanate. In the examples the cellular materials also contained dicumyl peroxide as catalyst, calcium carbonate or glass fibres as fillers, a polyadipate as plasticizer and diboric lead phosphite as stabilizer. As a test of heat recoverability the cellular material was heated, cooled under pressure to form a denser product and then re-heated to form an expanded foam.

Abstract: 1,222,666. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 17 Oct., 1968 [21 Oct., 1967], No. 49182/68. Heading H4F. Specification describes a system for a P.A.L. system colour television, for generating a chrominance sub-carrier signal f oa  in dependence on the phase and frequency of the line and frame frequency signals fH and fF respectively of an incoming television signal F.B.A.S. according to the formula where n is an integer. Thus a sub-carrier signal f oa  is generated by a voltage controlled oscillator 3 and appears at output 2. Said signal is also fed to mixer 6, where ¢fF (or 25 c/s when fF = 50 c/s) is subtracted therefrom. The resultant frequency (f oa -¢f F ) is divided by (n-) is divider 8 and the resultant pulse signal Ha<SP>1</SP> at line frequency is applied to one input of a phase discriminator 9. The line frequency signal H a  in the incoming television signal F.B.A.S a  is separated out in 10 and is applied to the second input of 9. The resultant voltage UR representing the phase angle difference # between the two frequencies is applied to variable reactance element 5 to vary the frequency of oscillator 3 until 9 becomes zero and the output at 2, viz, f oa , has the desired phase and frequency relationship of the formula above. The invention may be incorporated into a standards converter, Fig. 2, wherein an incoming television signal F a .B.A.S a  is converted to a signal F b .B.A.S b .

Abstract: 1518050 Arrangement of burners in coke oven flues DR C OTTO & CO GmbH 26 Nov 1976 [18 Dec 1975] 49352/76 Heading F4B In a Coppee type coke oven battery in which the coking chambers decrease in width from the coke KS side to the pusher side MS, the height at which rich gas burners 21 discharge into the heating flues increases towards the pusher side, MS, so as to give uniform heating over the coking chamber. The flues with rich gas burners discharging at different heights above the base may alternate with flues 10 having rich gas outlets at the base. In twin flues, one leg may have a high burner and the other leg have a base burner. Since the pusher side flues should receive less gas than the coke side flues, the extra height of the pusher side burners corrects for the shorter flame produced by less gas.

Filed: 1974-11-21
Abstract: 1477537 Cardiac pacer CARDIAC PACEMAKERS Inc 21 Nov 1974 50475/74 Heading A5R [Also in Division H3] In a cardiac pacer circuit comprising a steady current source 10, Fig. 1, provided with a lithium-iodide cell 16, a free-running multivibrator 12 having two stable states, and a voltage doubler circuit 14, the voltage waveform at an output junction 64 is as shown in Fig. 2 owing to the charging of a capacitor 52 by the steady current applied to the capacitor and resistors 54, 56, transistors 58, 60, and 62 being non-conducting during the charging of the capacitor, and discharging of the capacitor through a low-impedance path provided by a diode 74, a resistor 76 and the fully conducting transistor 62. The output voltage of the multivabrator 12, appearing at a junction 68 is fairly constant during the discharging of the capacitor 52 since the full voltage across the capacitor 49 is applied at the junction 68 owing to the low collector-emitter impedance offered by the fully conducting transistor 58. When the transistor 58 is switched-off, the voltage at 68 drops close to zero and during the time the voltage is at that level, a capacitor 90 is fully charged up to the voltage of the cell 16 by a steady current flowing through a resistor 100, a diode 116 across electrodes connected to the load 118, and a resistor 106 since transistors 92, 94 are in a non-conducting state. At the moment the capacitor 90 starts discharging through the load, the low-impedance collectoremitter path of the conducting transistor 92, the low-impedance cell 16 and the capacitor 22, and the low-impedance collectoremitter path of the transistor 94, the voltage across the load is approximately equal to the sum of the voltages of the capacitor and of the cell 16. The lithium-iodide cell is hermetically sealed and is implantable along with the circuit. The steady-current source 10 including transistors 24, 28 with matched characteristics, and trimmed resistors 30, 32, is designed to provide a decrease of six beats per minute in output pulse rate when the voltage across the load 112 drops to about 3.5 volts, thereby indicating the condition of the battery. The sum of the resistors 30, 32 is such that the multi-vibrator produces 72 pulses per minute, and it oscillates at 120 pulses per minute when the resistor 30 is shorted.

In a method and apparatus, Figs. 1 and 2, for the continuous manufacture of covered waffles, waffle sandwiches or biscuits, hereinafter referred to as sandwich biscuits, base sheets 13 for the sandwich biscuits are conveyed, close together in single file, on a conveyer of a coating machine 7, and are coated with a desired coating composition by a device 14. The coated base sheets are then transferred on to parallel conveyer belts 12, which travel faster than the conveyer of the coating machine, so that the coated base sheets are spaced apart, and are brought, one-by-one, under a cover-applying device 11, from which a baked cover sheet 1 is deposited on to each coated base. sheet as it is halted, momentarily, by camactuated lugs or stops 15, which are then retracted to allow the completed sandwich biscuit to be conveyed away from the device 11. The cover sheets 1 are conveyed, from an oven or ovens 2 to the coverapplying device 11, one-by-one in single file along a path which is at right angles to the conveyer of the coating machine 7. Along this path are disposed a shoot 3, a chain, conveyer 5 travelling between guide rails 4, an ejecting, device 9, two photoelectric sensers 8 and a vertical stack of spare cover sheets in a magazine 10. The sensers 8 detect any gap which may occur in the file of cover sheets. The sensers 8 also detect any damaged or otherwise unsuitable cover sheet in said file and actuate the device 9, which removes this cover sheet from the file and leaves a gap. The sensers 8 also respondingly activate gripping chains 17 located above the stack of cover sheets in the magazine 10, so that a cover sheet is transferred, from the top of the stack on to the chain conveyer 5, to fill the gap. The chain conveyer 5 and the two sensers 8 are controlled by a senser 16, preferably a photo-electric senser, which, on sensing the approach of a coated base sheet 13 towards the coverapplying device 11, starts movement of the chain conveyer 5, energizes the sensers 8 and activates the device 11.
