Title: Improvements in or relating to the manufacture of biscuits
IPC: A21D8/04
Filed: 1922-09-23
Abstract: 208,257. Barnett, H. T. Sept. 23, 1922. Biscuits.-In biscuit-making, the flour (i.e. cereal flour, powdered starch or meal) is cooked in a dry powdered condition and is then moulded by pressure into biscuit form with or without an agglomerant such as sugar, grease, flour or starch paste. The flour may be cooked in shallow trays in a gas oven, and flavouring, nourishing or medicinal substances may be added, preferably to the cooked flour, before moulding. The cooking may be effected, by a steam-coil in a bin, at 212‹ F. which temperature does not modify the colour or produce a flavour in the flour to spoil the delicate flavourings subsequently added. Coffee flavouring. absorbed by placing the biscuits in the fumes from coffee-roasting, vanilla or other volatile flavouring, or scents, such as attar of roses, may be used. An agglutinant, such as flour paste, may be brushed or sprayed on to the biscuits to retain the flavouring and to prevent chipping. Potassium bicarbonate or a small quantity of malt extract may be added to the cooked flour before moulding. Diastatic substances may be added before cooking, the temperature being raised gradually so that the diastase acts on the flour before the heat kills it. A small proportion of greasy substance, such as tasteless petroleum oil, facilitates absorption and retention of the flavouring. Reference has been directed by the Comptroller tu Specification 2307/75.

Title: Process for dyeing textile materials of highly polymeric linear aromatic polyesters
Filed: 1958-08-11
Abstract: Textile materials of linear aromatic polyesters are dyed with dispersed acetate, azoic or vat dyestuffs in the presence of a mixture of o- or p-hydroxy-diphenyl, a partially or completely hydrogenated aromatic hydrocarbon and an alkyl-aryl sulphonate. The mixture is preferably added to the dyebath in the form of an aqueous emulsion, the stability of which may be increased by the addition of a low molecular weight aliphatic ketone, such as acetone, diethyl ketone or methyl ethyl ketone, and/or a low molecular weight aliphatic carboxylic acid dialkylamide such as dimethyl- or diethyl-formamide or dimethyl-acetamide.  Mixtures of polyester fibres with natural fibres such as wool may also be dyed.

Title: Improvements in apparatus for attenuating and/or feeding a multi-filament strand
IPC: B65H51/06
Filed: 1956-08-23
Abstract: 832,522. Feeding &c. glass &c. fibre strands. OWENS-CORNING FIBERGLAS CORPORATION. Aug. 23, 1956 [Aug. 29, 1955], No. 25829/56. Class 120(2) Apparatus for attenuating and feeding a continuous multifilament strand comprises a rotary, generally cylindrical pulling wheel having a plurality of circumferentially spaced, periphery-forming elements, the outer surfaces of which form an interrupted cylindrical peripheral surface relative to the axis of said wheel for strand contact and adhesion, means for guiding said strand into approximately tangential contact with the peripheral surface of the wheel, means for rotating the wheel at high speed and a rotary strandremoval structure provided between the periphery-forming elements and rotatable simultaneously with the wheel and comprising a plurality of circumferentially spaced members movable radially outward through the spaces between adjacent ones of the elements on the wheel for progressively separating the strand from the cylindrical surfaces of the elements and from the pulling wheel. As shown (Figs. 6 and 7) the apparatus comprises an attenuating wheel 22 and an oppositely directed spider 32, the former having a series of circumferentially spaced lugs 27 and the latter having a plurality of circumferentially spaced, radially extending, fingers 37. The wheel 22 and the spider 32 are mounted for rotation with their axes 24 and 32 slightly eccentric. A multifilament glass fibre strand 13 is led into engagement with a cone-shaped edge 30 of the wheel 22 and, as the wheel and spider rotate clockwise, follows the end of a finger 37 until, after approximately a quarter turn, the strand is in full contact with the lugs 27. It remains so in contact for another half turn and thereafter the fingers 37 gradually protrude further and further between the lugs 27 and finally lift the strand off the lugs so that centrifugal force projects it away from the wheel. A further embodiment (Fig. 12) comprises a wheel 40 having lugs 44, between which balanced rockers 46 are mounted, and air from a jet 48 is arranged to tilt each rocker successively so lifting the strand away from the lugs. In a still further embodiment (Fig. 14), an attenuating wheel comprises a disc 50 having lugs 54 (similar to the lugs 27). A number of fingers 52 are pivotally connected at their inner ends to a hub 54 which is rotatably mounted on a stationary eccentric stub shaft 66 on the end of a stationary shaft 63, the disc 50 being rotatably supported by the shaft 63 and being driven by a belt 64. Because of the eccentricity of the axes of the hub 58 and the disc 50, the fingers 57 act in a similar manner to the fingers 37 to remove a strand 68.

Title: Improvements in article counting apparatus
IPC: G06M7/06
Filed: 1958-08-12
Abstract: 844,726. Counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 12, 1958 [Aug. 14, 1957], No. 25837/58. Class 106 (1). Article - counting apparatus comprises a differential mechanism with two input shafts, escapement means normally preventing movement of one of said shafts and article-sensing means adapted on the absence of an article to cause said escapement means to permit limited rotation of said one shaft, the output shaft of the differential being thereby temporarily brought to rest. As described, for counting tabulating cards, the cards 12, Fig. 1, are retained on a carrier-wheel 11 by equidistant clips 14. A gear 18 moving with the wheel 11 meshes with a gear 19 fixed to a shaft 20 which drives through reduction gearing 24, 26 a gear 27 which constitutes one input to a differential mechanism 28 and is fixed to a hollow input shaft 29 which surrounds an output shaft 31. A second input to the differential mechanism 28 is via a gear 37 driven by a pinion 38 fast on a shaft 39 normally stationary but which may be driven through a belt 41 by the shaft 20, the shaft 39 being provided with an escapement wheel 45 controlled by a latch 46 biased to engage the escapement wheel to prevent it from rotating unless the latch 46 is released.. The. latch 46 is fixed to a shaft 47 to which is also attached a finger 49 adapted to engage the cards 12 and so arranged that only when a card 12 is absent will the finger 49 pivot to disengage the latch 46, allowing escapement of one tooth of the wheel 45. A second finger 50 also fixed to the shaft 47 is then brought into position for engagement by an extension 16 of the clips 14 and allows escapement of one further tooth of the wheel 45 before re-engaging the latch 46. The differential mechanism 28 is so arranged that if the inputs from the gears 27, 37 are equal there is no output, but if there is an input from one side only, the output equals the input. A cam 57, Fig. 1, fixed to the output shaft, rocks an arm 58 once each revolution to indicate that a predetermined number of cards 12 has been counted. The operation is such that when a clip 14 holds a card 12, the tip of the finger 49 is engaged to hold the escapement wheel 45, preventing rotation of the shaft 39, and the output 31 of the differential mechanism 28 rotates to rotate the cam 57 by an amount representing one card 12 when a card 12 is missing, however, the finger 49 is urged clockwise by a spring 48, Fig. 3, to allow the escapement of one tooth, a second tooth being allowed to escape by rocking of the second finger 50. The gear 37 is therefore driven and reduces the output of the differential mechanism to zero for the missing card. In a modification (Fig. 7, not shown), the second finger 50 is replaced by a finger cooperating with a cam fixed to the shaft 20.

Title: Control of selectivity in radio receivers
IPC: H03G5/26
Filed: 1935-09-18
Abstract: 462,832. Valve circuits for wireless reception. MURPHY RADIO, Ltd., and MOXON, L. A. Sept. 18, 1935, No. 25913. [Class 40 (v)] The signal amplitude of a radio receiver is maintained constant from a certain point of the receiver onward, the selectivity being controlled from that or a subsequent point in dependence on the strength of undesired signals at the point from which the control voltage is derived. Fig. 1 shows a superheterodyne receiver in which the coupling between the frequency changer V1 and I.F. amplifier V2 comprises a network 5, 6 and valves V5, V6 arranged as described in Specification 442,685, the coupling being variable by varying the control grid bias of the valves. The coupling between V2 and the detector stage V3 comprises a second network 7, 8, V7, V8, exactly similar to that referred to above. Coupled to the anode circuit of V2 is an interference selecting network 10, 11, 12, V10, circuits 10 and 11 being tuned respectively 9 kc. above and below the intermediate frequency; when interference is present with the signal there appear across the load resistance 12 of the diodes V10 voltages of 9 kc. frequency arising from the beating of the interfering station with the wanted carrier. This frequency is amplified by V9 and passed to a filter 13 which is so designed that its characteristic, together with circuits 10 and 11, provides no response over the side band range of the wanted signal and a sharply attenuated peak response to frequencies 9 kc. on each side the wanted frequency. The output from the filter is rectified at V11 from the load resistance 14 of which control voltages are applied over conductor 15 to vary the grid bias of valves V7, V8 thereby varying the selectivity in accordance with ratio of interference to signal strength. To provide adequate control range, a further control voltage is taken from part of resistance 14 over conductor 16 to vary the coupling between V1 and V2 by the network 5, 6, V5, V6. The double-diode triode V3 has in its anode circuit a filter 4 to remove heterodyne whistle ; A.V.C. potentials for valves V1, V2 are applied over conductors 9 and 23. In the alternative system of deriving the control voltage shown in Fig. 3, the interference selector circuit is taken from V2 in parallel with the signal path and comprises circuits 17, 18 tuned to the I.F. but overcoupled to have resonant peaks 9 kc. each side that frequency. After rectification in V12, the harmonic thus produced is amplified in V13, the output being passed through an 18-cycle filter 19, 20. The double frequency output is rectified by V11 and applied to vary the couplings as described in Fig. 1. In a further modification of Fig. 3, the output from the circuits 17, 18 is applied to two pentodes V14, V15, Fig. 4, the anode circuits of which are coupled to circuits 19, 20, 21, 22, the circuits of each pair being timed one 9 kc. above, the other 9 kc. below the I.F. After rectification, the output is applied as in Fig. 1. Specifications 448,716, 450,081, and 451,227 also are referred to.

Abstract: 1,272,436. Bulk effect device pulse circuits. WESTERN ELECTRIC CO. Inc. 22 May, 1969 [27 May, 1968], No. 26242/69. Heading H3T. In a pulse circuit having two bulk effect semiconductor devices 10, 11 each biased to a voltage greater than the domain sustaining voltage but less than the oscillation sustaining voltage, bipolar pulses 20 are applied to a connection 21 between the devices so that each positive pulse of a suitable level causes the nucleation of a domain in one of the devices 11 and each negative pulse of a suitable level causes the nucleation of a domain in the other of the devices 10 to generate output pulses. The circuit may be used as a bipolar pulse regenerator. A positive pulse from 20 causes a domain to be nucleated in device 11 from its cathode 18 so that the current flowing through both devices 10, 11 is reduced giving a rise in output voltage V H  across a resistor 24 during the transit time of a domain ring device 11. Similarly a negative pulse causes device 10 to nucleate a domain from its cathode 19 to give a lower output V L . The D.C. supplies 12, 13 may be replaced by controlled sources so as to permit AND gating operation to be performed on the bipolar input. The length of the two devices 10, 11 can be different so as to give different width positive and negative output pulses. The devices may be of gold doped Ge, CdS, GaAs, InP, CdTe or ZnSe.
