Title: Improved manufacture of stencil-sheets for autographic and typewriting duplication purposes
IPC: B41N1/24
Filed: 1923-03-14
Abstract: 201,882. Koreska, W. Aug. 1, 1922, [Convention date]. Varnishes.-A coating-composition for stencil sheets for use in duplicating machines comprises derivatives of cellulose, an oil and a normally solid fatty substance of mineral, vegetable or animal origin. Inorganic or organic esters of cellulose, oxy-cellulose or hydro-cellulose or hydrated cellulose precipitated from solutions of cellulose or cellulose esters may be employed. The composition may also include a mixture of esters and hydrated cellulose such as is generated when nitro-cellulose is partly denitrated. As examples of fatty substances tallow, the fatty acid of cocoanut oil and paraffin residues are given. A volatile solvent is preferably used consisting, for example, of tetrahydronaphthalene or decahydronaphthalene where hydrocarbons or fats are chosen as the fatty substance. Amyl acetate or a mixture of ethyl ether and alcohol may be used if the substance is a fatty acid or a substance soluble in these solvents. To produce a coating consisting wholly or partly of hydrated cellulose, the coating applied to the sheet is treated with a suitable precipitating liquid e.g. a coating comprising nitrocellulose may be softened by partly denitrating it. A specific example of a suitable ccmposition is given as 400 grms. of nitrocellulose, 800 grms. of castor-oil, 1,000 grms. of tallow and 10 litres of amyl acetate.

Bale-tie fasteners. - A joint for metal girths for boxes, bales barrels, &c., is formed so that the maximum deformation and interlocking occurs in the centre of the joint, while the tensile strength of the joint adjacent the ends thereof is only slightly reduced by deformation. In the form shown in Fig. 2, a sleeve A encircles the overlapping ends B, C of a steel band, and is indented at 10, 11 on opposite sides to form interlocking deformations. Three deformations 13 are made in the centre of the joint, two pairs 14 on each side thereof, and single indentations 15 adjacent the ends. In the form shown in Fig. 5, a sleeve E and overlapping ends B, are sheared relatively deeply at 20 in the centre of the joint, lesser shearings 21 having formed nearer the ends, and in Fig. 6, the deformations 22, 23 by edgewise pressure are greater than those at 24. In another form, Fig. 8, a wire tie in twisted tightly at 38 and less tightly at 40.

Abstract: 813,222. Stud and socket fastenings; nuts &c. UNITED-CARR FASTENER CORPORATION. March 6, 1957 [March 6, 1956], No. 7497/57. Classes 44 and 89(1) A fastening device for attachment to a stud comprises one short metal member 20 having a series of resilient fingers 26 the inner edges of which define an aperture 24 for receiving and engaging the stud, and a resilient seating washer 22 disposed on one side of the aperture the sealing washer having means 32 projecting into and retained in the stud receiving aperture retaining the washer and sheet metal member in assembly. The washer 22 is of generally conical shape and the means projecting into the aperture 24 is a hollow nib which is larger than the aperture 24 so that when the washer is assembled with the member 20 the fingers engage the exterior surface of the nib and pinch it slightly forming a shoulder 38 which assists in retaining the parts in assembly. When the fastening device is assembled on to a stud by forcing it over the stud the fingers sheer the nib from the remainder of the washer and since the diameter of the opening in the nib is less than that of the stud the stud is gripped tightly by the washer and so seals an aperture 18 in the panel through which the stud penetrates, against the entrance of dust and moisture.

[Also in Group IX] A process for continuously drying and setting crimped tows of endless synthetic filament issuing from a compression chamber 1 packs the tows with a traversing action (at 2, Fig. 1) into a hollow shaft 3 in which they are moved continuously forward by their own weight and are brought into contact along sections of their travel 6, 10 with streams of hot air or saturated steam, and thereafter of cold air, directed at right-angles to their path. The apparatus for this process has a rectangular shaft (Fig. 3) vertically below the chamber 1 with the sections 6 and 10 jacketed and provided with diametrically opposed openings and with supply and discharge pipes 8, 12-9, 13. Movement of the tows through the shaft may be controlled by curving the end of the shaft as in Fig. 2, or by operation of a pair of hinged plates 4, counterbalanced by weights at 5, which open to discharge successive batches of the tows each time the weight of the latter accumulated in the shaft overcomes the force due to the counterweights.

Abstract: 1,181,304. Semi-conductor timing circuits. MALLORY TIMERS Ltd. 17 Feb., 1967 [28 Feb., 1966], No. 7710/67. Heading H3T. [Also in Division H2] A circuit for supplying pulses to a load comprises a timing circuit 42, 43 for alternately triggering a bi-stable circuit 27, 33 between first and second states, an electronic switch 23 having the load connected in series therewith and operated by the output from the bi-stable circuit, and means such as 44 associated with the timing circuit for adjusting the times for which the bi-stable circuit is in each state, the total duration of two successive periods being independent of the setting of adjustment 44. With transistor 27 conducting and transistor 33 non-conducting, capacitor 43 charges through resistor 45, diode 38 and resistors 40, 44 until unijunction 42 fires, reducing the potential on the base of transistor 27, thus cutting off transistor 27 and switching on transistor 33. With transistor 27 non-conducting, a positive potential is applied to the gate of SCR 23, which SCR fires to supply the load, connected between point 10 and either point 11 or 14, the A.C. source for the circuit being connected between point 10 and either point 12 or 15, respectively. The bi-stable circuit re-triggers when capacitor 43 has recharged, this time through resistor 29, diode 35 and resistors 39, 44, to fire unijunction 42. The mark/space ratio of the pulses is adjusted by divider 44, and the frequency may be adjusted by a variable resistor connected between the wiper of resistor 44 and capacitor 43.
