IPC: C08G75/10
Filed: 1930-08-22
Abstract: In the preparation of lacquers, varnishes, and coating compositions, a synthetic resin is employed which is prepared by condensing an alkyl, aryl or aralkyl mercaptan with an aldehyde, ketone or compound containing a reactive methylene group. Examples of mercaptans are thiophenol, thiocresol, thioxylenol, benzyl-mercaptan and dithiophenylolpropane; formaldehyde, paraformaldehyde, acetaldehyde, hexamethylenetetramine and acetone are mentioned as second components.  A cellulose derivative may be added to the resin, together if desired with other ingredients such as solvents, plasticizers, softeners, and colouring materials.  Cellulose derivatives mentioned are the nitrate, acetate, formate, propionate and butyrate, and the ethyl, methyl and benzyl ethers.  Triacetin, diethyl tartrate and dibutyl tartrate are referred to as suitable plasticizers.ALSO:Synthetic resins are prepared by condensing an alkyl, aryl, or aralkyl mercaptan with an aldehyde, ketone, or compound containing a reactive methylene group.

Abstract: 1534198 Semiconductor matrix stores TOKYO SHIBAURA ELECTRIC CO Ltd 18 June 1976 [20 June 1975] 25298/76 Heading G4C In a matrix store comprising an array of semiconductor memory cells 10, a row selection circuit 14 is located between the outermost columns of the matrix array to reduce the time required for row selection. Preferably the row selection circuit 14 is located substantially at the middle of row selection lines 12. This is particularly advantageous when the row selection lines 12 are formed of a high resistance material, e.g. a polycrystalline silicon layer. The matrix store may be formed on a semiconductor substrate and the memory cells 10 may comprise IGFETs having polycrystalline silicon or metal gates. The columns are selected by means of pairs of column selection lines 11A, 11B, one of each pair being a polycrystalline silicon layer and the other being a metallic layer. A column selection and I/O control circuit 13 is therefore preferably located between the outermost rows of the matrix array, Fig. 2 (not shown) or the two embodiments combined. Respective pluralities of the row selection circuits and of the column selection circuits may be provided. As shown, each row position of the row selection circuit 14 has two outputs connected to respective halves of the row selection lines 12, but a single output connected to the entire row selection line may be provided. A similar modification of the column selection circuit may be used.

Title: Adjustable cam assemblies

Filed: 1974-06-07
Abstract: 1459688 Time switches APPLIANCE COMPONENTS Ltd 12 May 1975 [7 June 1974] 25460/74 Heading H1N [Also in Division F2] Fine and coarse adjustments of an angularly adjustable cam assembly readily ensure precise circumferential positioning of a cam ring 20 on a drive shaft 1. The cam ring 20 is mounted on a sleeve 2 formed as a worm wheel and is circumferentially positioned thereon for fine adjustment by a worm screw 13 in the cam ring 20 engaging the worm wheel teeth of the sleeve 2, which sleeve 2 is a friction-fit on the drive shaft 1 whereby initial coarse angular adjustment of the cam ring 20 and sleeve 2 as a unit is readily effected simply by relatively forcibly turning the cam assembly on the shaft 1 i.e. overcoming the friction-fit to re-position the sleeve 2 on the shaft 1. The cam ring 20 and sleeve 2 are of thermoplastics and the shaft 1 of stainless steel. A number of such cam assemblies may be arranged as a multiple cam timer unit (Fig. 4, not shown) for a beverage vending machine or a gaming machine (not shown). The cam assemblies are mounted side-by-side on the cam shaft 1 which is journalled in end brackets (21) and is driven through a gear train in a housing 22 by an electric motor in a housing 23. The other end of the cam shaft carries a cam setting knob (24). A number of switches (25), one for each cam, are mounted between the end brackets (21). Each cam is shaped with a notch (26) and flats (27) for engagement by a holding key (28, Fig. 5, not shown) which can be slid downwardly on to the cam and is shaped to seat on the casing of the associated switch (25) whereby the cam assembly may be held stationary as the cam shaft is rotated by the cam setting knob (24) to effect the coarse adjustment of each cam assembly on the shaft 1, and when the approximate required angular setting is achieved the holding key (28) is removed from the particular cam assembly and the fine adjustment achieved by turning the worm screw 13.

Abstract: 1,158,378. Dump scraper. GUSTAV SCHADE MASCHINENFABRIK. 28 May, 1968 [12 Feb., 1968], No. 25504/68. Heading B8E. A dump 2 is discharged by endless rake conveyer 10b which is carried pivotally at 9 by frame 1 which spans the dump and runs on rails 4 positioned at either side of dump 2. The conveyer scrapes away the side of dump 2 and discharges the material through hopper 17 on to discharge conveyer 7. The conveyer is supported by cable 12 operated by winch 11 and itself passes through aperture 20 formed in frame 1 so that when the frame has run along the length of the dump 2 and conveyer 10b has taken off one layer of the dump the conveyer is dropped one step by means of the winch 1 so that when the cycle is repeated a further layer of material from the dump is discharged at 7. Thus, as the conveyer pivots downwardly it passes downwards through the aperture 20 of the frame 1 to the lower position shown, and both the aperture and the conveyer at 20 are provided with strips to assist the resultant sliding contact.

Abstract: 255,072. I.G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). July 7, 1925, [Convention date]. Azo dyes; lakes.-Azo dyes are produced, either in substance or on the fibre or on a substratum, by coupling diazotized o-amino-arylsulpho-alkyl (or aralkyl)-arylides of the general formula (R=arylene, R1=alkyl or aralkyl, R,=aryl) with arylides of 2:3- -oxynaphthoic acid or with acetoacetic arylides. According to examples (1) a scarlet-red dyestuff is produced from diazotized o-aminophenyl-methyl-amide of benzenesulphonic acid and 2 : 3-oxynaphthoic-o-toluidide; (2) greenish-yellow shades are produced on cotton by grounding with diacetoacetic-o-toluidide and developing with the diazo compound of example (1); (3) cotton is dyed red by grounding with 2 : 3-oxynaphthoic-5-chlor-2-toluidide and developing as in (2).

Title: An improved process for making lead sulphate
IPC: C01G21/20
Filed: 1919-10-18
Abstract: Metallic lead is treated with oleum at 150 DEG  C. and the reaction is then continued at a lower temperature, say about 100 DEG  C.  If the lead is first coated with a more electronegative metal such as mercury, copper, or silver, for instance by treating with mercury or copper sulphate, or if a compound of such a metal is added to the reaction mass, the reaction begins at 90-100 DEG  C. and continues without external heat.  An excess of oleum is preferably used, and the lead sulphate is precipitated by addition of water.  If bismuth or silver are present in the lead the sulphates are obtained in the solution after the removal of the lead sulphate.  The excess acid may be recovered.

Abstract: 1,131,008. Capacitive sensors. LUWA A. G. June 2, 1967 [June 2, 1966], No.25656/67. Heading G1N. [Also in Division D1] Discontinuities such as breaks or fragmented pieces in a fibre strand (30, Fig. 2, not shown) are detected by a capacitance transducer 21, Fig. 1, the value of which is varied by making the strand form part of the dielectric, or by making its discontinuities strike one of the plates of the capacitor to deflect it, the capacitance variations being used to vary the bias on the gate G of a F.E.T. 10 the output 22 of which is amplified and indicated by means not shown. The F. E, T. circuit, which may be connected to a plurality of measuring capacitors, includes a feedback capacitor C19; and also an input capacitor C17 which with a bias resistor R15 constitutes a time constant rendering the circuit responsive only to signals above a certain frequency and magnitude. The circuit thus responds to series of pulses due to breaks or other discontinuities of substantial size in the strand, but not to occasional or slow capacitance variations due to minor causes such as suspended fibre particles and fluffy lumps. Breakage of a strand (30) approaching a rotating flyer (34) is detected by placing the sensing capacitor (44) in a suction channel (41) which through a pipe (40) sucks in the broken ends or fragmented pieces of the strand until they affect the capacitor. Breakage near the outlet of a container (31) feeding the strand (30) is detected by placing a further capacitor transducer (21a) where it will be contacted by a sag (30') in the strand if it breaks. Accumulation of fluff (52, Fig. 3, not shown) at the flyer (54) is detected by another transducer (21b).
