Title: Improvements in method of preparing a multi-leaved edge for receiving colored markings and the article resulting therefrom
IPC: B41F17/24
Filed: 1944-10-10
Abstract: 584,024. Printing processes. OPPENHEIMER, H. E. Oct. 10, 1944, No. 19508. [Class 100 (ii)] [Also in Groups XV and XVIII] An inclined stepped edge consisting of the tips of a large number of sheets, such as a telephone book, is prepared for printing by smoothing the stepped edge by removing portions of adjacent tips. The edges of the book &c. may be normally perpendicular to the sheets, in which case the sheets are flexed to provide a stepped edge; alternatively, as shown in Fig. 11, the edges 72 of the leaves of a book 70 may be inclined, the sheets being of increasing width or of the same width, a wedge-shaped stiffener 78 being incorporated in the binding in the latter case. The removal of portions of the tips may be effected by a milling-cutter, sand blast and stencil, or by a rotary grinding-wheel, applied to the whole or parts only of the inclined edge to provide a flat or slightly arcuate surface, and grinding may be followed by glazing and sizing. Printing may be type or plate printing, stamping, stencilling, photo-mechanical, decalcomania or by metal powders, and may consist of indexing characters. The sheets may be flexed in one direction and after grinding flexed in the opposite direction for a second grinding operation to produce tips 22" as shown in Fig. 7. Two different designs may be printed in the alternative positions so that a design such as 53, Fig. 8, shows when the sheets are bent in one direction and a design such as 54, Fig. 9, when bent in the other direction. The edges may be smoothened when the sheets are inclined in one direction and the sheets inclined in the reverse direction for printing.

Title: Circuit Arrangement for Addition and Subtraction
Inventor: GLASER EBERHARD
IPC: G06F7/50
Filed: 1967-04-28
Abstract: 1,175,410. Adders and subtractors. ELEKTRONISCHE RECHENMASCHINEN - WISSENSCHAFTLICHER INDUSTRIEBETRIEB-KARL-MARX-STADT, VEB. 28 April, 1967, No. 19631/67. Heading G4A. A binary-coded-decimal addition and subtraction arrangement includes a serial full adder-subtractor, a pre-correctoin circuit for the negation of the highest-significance bit in a tetrad in the case of correction and correction means connected to a flip-flop register for adding or subtracting two to or from the precorrected tetrad. Binary-coded decimal digits (8421 code) A, B are applied to serial full adder-subtractor 1, sum (or difference) signals S<SP>1</SP> being produced by the upper half of the adder-subtractor and passed along flip-flop chain 16, 24, 25, 26. Carry (or borrow) signals U are produced by the lower half of the adder-subtractor. At time t 4 , a tetrad is in position in the chain 16, 24, 25, 26, least significant bit in 26, and a flipflop 27 is reset via OR 30 since the lowest order bit never requires correction (see below). At the next time interval, t 1 , if the carry signal U is present, indicating the need for correction, AND 18 causes ANDs 19, 20 and OR 22 to invert the highest order bit of the tetrad, and sets flip-flop 27 to invert the next-to-least significant bit (at least) by means of ANDs 31, 32 and OR 33. A 1 from flip-flop 26 during addition, or a 0 during subtraction, resets flipflop 27 again, via ANDs 28, 29. Thus correction is performed, when required, by addition or subtraction of 8 at ANDs 20, 19 &c. and by addition or subtraction of 2 at ANDs 31, 32 &c. Note the feedback via OR 34 from flip-flops 16, 24 to AND 11 in adder-subtractor 1. It is mentioned that blocking of ANDs 11, 18 by extra inputs would produce pure binary rather than binary-coded-decimal operation.

Title: Improvements in or relating to electrically heated hair-waving appliances
IPC: A45D4/12
Filed: 1934-07-04
Abstract: 427,596. Hair -waving appliances. ELECTRICITATSGES. SANITAS, 35, Miillerstrasse, Berlin. July 4, 1934, Nos. 19701, 19702, 19703, 19704, and 19705. Convention dates, July 4, 1933, Feb. 3, 1934, March 17, 1934, March 17, 1934, and April 25, 1934. [Class 131] In hair - waving apparatus comprising a plurality of curling appliances each consisting of an electricallyheated curler for heating the coiled tress internally and an electrically - heated clip or sheath for heating the tress externally, the current to all the appliances is controlled by a single switch mechanism which enables current to be supplied either to both the internal and external sets of heaters together or to one of the sets of heaters separately. In modifications, the switch is arranged to enable each of the two sets of heaters to be used separately. As shown in Fig. 1, one of the current supply leads is connected in parallel to the set of internal heaters 1, and the set of external heaters 2, the individual heaters in each set being arranged either in series or in parallel, and the other lead is connected by a switch 3 and regulatable resistance 4 to the external heaters 2, and by a switch 5 and resistance 6 to the internal heaters 1. The switches 3, 5 may be replaced by a rotary switch which can be set to supply current to both or either set of heaters. The current may be supplied from a transformer, the switch and circuits being arranged to enable current at a higher voltage to be supplied when the external heaters are used alone than when both sets of heaters are used. In a modification, two switches are employed, the arrangement being such that current at two alternative voltages may be supplied both when the two sets of heaters are used together and when the external heaters are used alone. The transformer may be mounted in the base of a stand, the head of which carries the switch mechanism and is provided with a series of sockets for the leads of the heaters. In further modifications, when the switch is operated for simultaneous external and internal heating, the current to either or both sets of heaters is reduced by short circuiting a resistance in one or both circuits. The external heater may comprise a resistance 2, Fig. 8, mounted between two complementary shells 26 which are held together by spring clips 27 and surround the curler 1. The shells 26 are provided with insulated handles 30 and with parts 29 gripping tightly around the ends of the curler. Current may be supplied to the terminals 32 at the end of the resistance 2 and of the curler 1 by wires 31 joined to a coupling member 34 having sockets engaging the terminals, or may be supplied by a single wire 36 attached by a coupling 37 to the terminal 38 of the resistance 2, the terminal 39 of the curler 1 being provided with a ring 40 engaging a spring 41 on the terminal 38.

Title: Improvements in or relating to radial cylinder reciprocating pumps
IPC: F16N13/10
Filed: 1946-07-03
Abstract: 626,646. Intermittent gearing. TECALEMIT, Ltd., and LE CLAIR, C. C. S. July 3, 1946, No. 19959. [Class 80 (i)] [Also in Group XXVIII] Toothed gearing for connecting continuous rotation of a reciprocating pump shaft 15, Fig. 1 (see Group XXVIII) to step by step rotation of a plunger actuating bolt housing 13 comprises a two armed member 40 secured to a sleeve 11 which carries the housing 13 and also a gear sector 42 and a retaining arm 60 on a pivot pin 41. The sector 42 carries a roller 43, Fig. 6, spring urged into engagement with a cam 45 secured to the shaft 15. Rotatably mounted on a cam boss 49 is a double armed member 50, Fig. 7, one arm 51a of which carries a pivoted pawl 55 spring urged into one of 12 notches 57, Fig. 8, in a fixed ratchet 59 so as to permit the member 50 to be rotated in a clockwise direction only. The other arm 51 forms a gear wheel sector having teeth 53, Fig. 7, engaging those of the sector 42. A step of the arm 40 and the housing 13 of one-twelfth of a revolution occurs as the surface 45a of the cam 45 swings the sector 42 clockwise about the pin 41 against the spring 46. The sector 42 tends to swing the pawl carrying member 50 in an anticlockwise direction but since this is prevented by the ratchet 59 the sector 42 is forced to roll on the teeth 53 in epicyclic manner thereby causing a roller 61 on the retaining arm to slide over a tooth 58 from one notch to the next and pin 41, member 40, sleeve 11 and the housing 13 and bolt 27 to make a clockwise step. During the remainder of the cam cycle during which the plunger cycle is effected, the engagement of the roller 61 in the appropriate notch 57 is such as to hold the housing 13 against rotation. In a modification wherein the housing is carried by a hollow sleeve rotatably mounted about the shaft 15 and carrying a pivoted planet pinion 80, Fig. 10, the indexing gearing comprises a fixed spur ring 78 having 48 teeth, and four teeth 82 cut on the inner surface of the worm wheel 18. The pinion 80 is formed of a lower zone of eight teeth 80a meshing with teeth 77 and an upper zone of four teeth 80b which form a lock for the pinion when they engage the plain cylindrical part 81 of the wheel 18. On engagement of teeth 80a and 82 the pinion is rolled round the spur ring 78 in epicyclic fashion to rotate the bolt and housing one twelfth of a revolution. Specifications 567,644 and 592,386, [both in Group XXVIII], are referred to.

Title: Foamed products
Inventor: BUTTREY DOUGLAS NORTON
IPC: C08J9/08
Filed: 1961-06-05
Abstract: The invention provides, as new materials, foamed solid products comprising thermoset co-condensates of urea and furfuryl alcohol with formaldehyde. They can be obtained by treating a urea-furfuryl alcohol-formaldehyde condensate having a pH not less than 7 with a blowing agent and an acid or latent acid hardener for the co-condensate and causing or allowing the co-condensate to foam and to thermoset under the action of the blowing agent and the hardener. Preferred blowing agents are those which generate a gas by reaction with an acid without the application of heat, e.g. sodium carbonate or bicarbonate or calcium carbonate in combination with phosphoric acid.  A plasticizer such as a di- or trihydric alcohol can be included in the mixture before the hardening.  In examples the co-condensate is prepared by reacting urea and formaldehyde at pH 7.5, then adding urea, furfuryl alcohol and formic acid (to produce pH 6.5), reacting further, cooling, and adjusting the pH to 7.  After dehydration finely divided sodium bicarbonate is milled in and foaming is effected by addition of (1) aqueous orthophosphoric acid; (2) wetting agent, polypropylene glycol and aqueous orthophosphoric acid.
