Title: Process for regenerating waste paper
IPC: D21C5/02
Filed: 1963-08-16
Abstract: Waste paper is regenerated by pulping it in an aqueous bath that has been softened by adding an alkali-metal silicate and also contains an oxygen-yielding substance and a detergent that is a primary or secondary alkylsulphonate having a hydrophobic hydrocarbon radical of 10 to 20 carbon atoms or an alkyarylsulphonate having 6 to 15 carbon atoms in the side chain, or a mixture of these.  The hardness of the water is then adjusted to at least 10 DEG  German hardness and the pigment particles removed by flotation.  A water-soluble salt of an organic carboxylic acid having 10 to 22 carbon atoms or an alpha-sulphonic acid derivative thereof may also be present as a hardness-sensitive surface-active agent.  The oxygen-yeilding substance may be sodium peroxide.  The hardness may be adjusted by adding a salt of calcium or magnesium. The paper may also be bleached and comminuted at the same time.

Abstract: 342,268. Aircraft wing structures. WALLIS, B. N., Weybridge Works, Byfleet Road, Weybridge, Surrey. Oct. 26, 1929, No. 32574. [Class 4.] Aircraft wings having a framework comprising longitudinal spars and transverse ribs have stringers connected to the ribs in the direction of the span so that their outer surface projects outside the ribs, the outer surfaces of the stringers being so located that a fair curve surrounding them in the direction of the chord gives the required wing section, and a flexible outer covering which when attached does not contact with the ribs but assumes the required contour. A wing, Fig. 1, comprises a built-up spar 1 of the type described in Specification 334,405, [Class 4, Aeronautics], transverse ribs 4 supported at the junctions of the spar bays, stringers 8, and an outer covering 14. The stringers 8 are arranged to conform with the wing shape for instance as shown in Fig. 1 and the spacing between them is adjusted to suit the aerodynamic loading at different points in the chord. When fabric covering is used light flexible battens may be arranged transversely or diagonally with respect to the stringers. Each rib 4, Fig. 2, comprises wire braced leading and trailing edge sections and upper and lower centre sections, each section being secured by plates 9 to the flanges of spar strengthening sleeves 2. The ribs comprise angle members 4a, 4b, Fig. 2, connected by pressed bracing pieces 4c. The stringers are of similar construction having flanges 8a, 8b and are secured to the ribs by angle-strips 10 riveted to the members 4a, 4b. The ribs need not be shaped to the profile, this being determined by the arrangement of the stringers. The tubular spars may be formed from helically wound strip metal.

Abstract: 1,003,194. Switching arrangements for heating resistors. SIMPLEX ELECTRIC CO. Ltd., and ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 12, 1962 [Sept. 12, 1961], No. 32609/61. Heading H2H. A hot plate 10a is heated during its starting period by a boost, resistor R1a with or without the aid of a running resistor R2a which, upon de-energization of the resistor R1a after a predetermined period, maintains the plate at its required temperature through intermittent operation of regulator contacts 11a controlling the current supply to both resistors. In operation of the circuit shown rotation of an operating member 19 closes normally-open contacts 11a, 18 to energize the resistors R1a, R2a and heating resistors R3a, R4a which control bimetal strips 12a, 14a for operating contacts 11a, 13a, opening of the latter deenergizing the resistor Rla. The member 19 includes cams 20, 22 for adjusting the position of the contacts 11a, 13a or the position or stressing of their bimetal strips, such adjustment varying the ratio of the on/off periods of the contacts 11a and the time for which contacts 13a remain closed, and hence the degree of boost during starting. If only resistor R1a is used during starting, the bimetal strip 14a is used to close normally-open contacts in series with the resistor R2a when contacts 13a are opened. The switch 18 may be omitted and only contacts 11a be adjustable, Provisional Specification drawing (not shown). Each bimetal strip may act as its own heating resistor and contacts 11a, 13a may be operated other than thermally, e.g. by a cam or other rotary device driven by a common shaft. Specification 818,371 is referred to.

Title: Synchronised mechanism for biscuit manufacturing machines and the like
IPC: A21C11/16
Filed: 1957-10-24
Abstract: 865,978. Biscuit-making machines. ATELIERS DE CONSTRUCTION GUILLAUME OOMS S.A. Oct. 24, 1957 [Nov. 3, 1956], No. 33179/57. Class 87(2). Biscuit-making machines with means for forming bare biscuits, means for applying a garniture thereto and a common conveyer are provided with synchronized mechanism wherein both the said means are interconnected so as to be forced to perform the same translational motion, control means common to both said means being provided for controlling the dispensing of the substance to be supplied as the garniture. Dough paste is discharged through outlets 2 in the bottom of a hopper 1 and forms biscuit shapes 5 on the surface of a conveyer belt 3, the hopper reciprocating, on rollers 9, parallel to the direction of travel of the belt. At a further position 4 in the direction of travel of the conveyer, edible decorative material is deposited on the biscuit shapes. A cam 17 on a driven shaft 18 rocks an arm 12 and, through linkage 10, 11, operates known mechanism to open and close the outlets 2. The decorative material or garniture is supplied through a pipe 43 to a chamber 37 and is discharged through bottom outlets 39, controlled by a slide 35 which is reciprocated so that holes 41 therein are alternately in and out of alignment with holes 42. The reciprocation is caused by a doubleacting piston 26 in a cylinder 27 which is supplied at alternate ends with compressed air as directed through pipes 28, 29 by a solenoidoperated valve 30. The solenoids are energised through switches 23, 24 which are actuated by detents 20, 22 on a disc 19, their relative positions being adjustable. Thus the time during which the passages 41, 42 are open, and thus the amount of material deposited, is controllable; also the two depositors are in synchronism, the operation of both being derived from the same shaft 18. Rigid connections 6, 7 cause the chamber 37 to reciprocate with the hopper 1.

Filed: 1962-08-29
Abstract: 1,022,122. Spray burners. SOCONY MOBIL OIL CO. Inc. Aug. 29, 1962 [Aug. 31, 1961], No. 33182/62. Heading F4T. An oil burner of the type in which an oil supply tube terminating in a nozzle 4 is disposed centrally in an air supply tube 2, has an annular shield 1 of heat-insulating non- metallic refractory material attached to and closely fitting in the open end of the air tube 2 the shield 1 being shaped to define a short frustoconical air flow path followed by a divergent section for the burning mixture of oil and air. The shield supports a coaxial air director 3 of similar material the oil tube and ignition means 10 passing through a central hole 6 in the air director while a plurality of holes or passages 7 each disposed at approximately 45 degrees to both the axis of the air tube and the radius of the air director provide for the passage of a swirling flow of air producing intimate mixing of the oil spray and air. The effect of the shield is to stabilize the flame which tends to establish itself along the divergent surface of the shield; pulsation of the flame with its attendant noise is thereby reduced. Furthermore the oil nozzle is partly protected from radiation from the flame and hot surface of the shield and therefore operates at a lower temperature and also cools more rapidly after shut-off; by this means the formation of carbon deposits in and around the nozzle is significantly reduced.

Abstract: 677,158. Sight-testing apparatus. HILL, R. F. Nov. 24, 1950 [Dec. 29, 1949], No. 33244/49. Class 97 (i). Apparatus for testing binocular vision comprises a fixation target arranged to present to the observer, either directly or through a mirror system, a normal binocular projection of a pair of spaced images carried thereby and septum means which can be arranged to dissociate said images, or a similar pair of images carried by the target, with respect to the eyes of the observer whilst allowing both eyes to observe a common confined area between the dissociated images to stimulate the binocular reflexes, whereby a comparison can be obtained between the normal binocular poise of the observer and the binocular poise when the observer's eyes are dissociated. As shown in Fig. 4 a target 9 bearing two identical pairs of images RL is viewed by the observer's eyes 3 by reflection in a mirror comprising a large reflecting area 10 and a small reflecting area 12 limited by non-reflecting areas 11, the edges 11a of which form septa so that each eye views only one image of the lower pair by reflection in the mirror portion 12, together with an area common to the vision of both eyes, while each eye sees both the upper pair of images by reflection in the portion 10. The difference in the two views gives an indication of any defects in the binocular vision of the observer. Alternatively the reflector 12 may be a separate mirror hinged to the mirror 10, the portions 11 being formed as screens movable to vary the extent of the effective reflecting surface. The mirrors 10 and 12 may be relatively inclined so that only one pair of images R and L need be provided on the target 9. In a modification, the target 9 may be directly viewed through a mask 7, Fig. 2, having an area 8 through which the upper images are viewed by both eyes and a slot 8a, the edges 8b of which form septa for dissociating the lower images. The target and mask may be slidable on a rod for relative adjustment.
