Title: A new selvedge for woven material having separate wefts formed of measured lengths of thread and means for producing same
IPC: D03D47/46
Filed: 1924-02-08
Abstract: 214,198. Ateliers des Vosges. April 14, 1923, [Convention date]. Selvages, special, fabrics with.-Selvages are formed on fabrics of the kind in which the wefts a, Fig. 1, each consist of a single or double measured length of thread which is drawn into the shed by hooks, clamps, hook shuttles, &c., by weaving a separate selvage weft e into the cut ends of the wefts and the warps b at the borders of the fabric. A selvage weft loop f may be inserted with each shot of weft a as shown. with each alternate pick, or after every third pick. The selvage thread e is inserted into the fabric during the weaving of the latter by a curved hook 6, Figs. 3, 4 and 6, having an eye through which weft e passes from a bobbin, and a co-operating needle 20. The hook 6 is secured to a spring-controlled rod 3 slidably mounted for example on a drum 1 on the temple and is oscillated by a rack and pinion from a cam on the tappet-shaft. The needle 20 is reciprocated vertically by a cam on the tappet-shaft and is guided in an arm 27 on the lay, a spring normally holding it towards the right as shown in Fig. 3. In operation, the hook 6 passes a loop of selvage weft e through the shed, the end of the loop projecting above the warps as shown in Fig. 6 The needle 20 is then raised and retains the loop after the hook 6 has been withdrawn. After a weft a has been inserted, the reed 18 beats up and moves the needle 20 and the rod hook 6 towards the fell of the fabric, the needle 20 being lowered just before the. threads are finally beater up.

Title: Improvements in the formation of coatings from stoving enamels
Inventor: HANDLEY CYRIL MONCKTON
IPC: B05D7/16
Filed: 1954-02-04
Abstract: Enamel coatings on metal surfaces (see Group III), are based on synthetic resins.  In one example the enamel comprises a phenol-formaldehyde resin dissolved in a mixture of alcohol, methylated spirit and ethyl lactate.  22.2 per cent by weight titanium dioxide and 4.0 per cent china clay may be added as filler. In another example, the enamel is based on an epichlorhydrin resin (i.e. a condensation product of epichlorhydrin and a dihydric phenol, crosslinked, e.g. with an amine) reacted with a phenolic resin.  The enamel then comprises 48 per cent epichlorhydrin-phenolic resin dissolved in 30 per cent diacetone alcohol and 22 per cent toluene, percentages by weight.  A filled enamel comprises 30 per cent of the above resin and 25 per cent rutile, 22.5 per cent diacetone alcohol and 22.5 per cent toluene.  Specification 655,264 is referred to.ALSO:A method of forming coatings on metal surfaces, e.g. of vats or tanks, from stoving enamels based on synthetic resins comprises applying, e.g. by spraying (a) a first film of filled enamel and lightly baking it; (b) a second film of unfilled enamel and allowing it to dry; (c) a third film of a filled enamel and lightly baking it; (d) a fourth film of unfilled enamel, the composite coating being finally stoved.  The resin may be a phenol-formaldehyde resin in the "A" stage of condensation, and the filler a mixture of titanium dioxide and china clay, baking temperatures being 175 DEG F. and 200 DEG F. respectively, and the stoving temperature 320 DEG F. Alternatively, the enamel may be an epichlorhydrin resin, e.g. cross-linked with a phenolic resin, dissolved in diacetone alcohol and toluene, the filling being rutile, the baking temperature being 300 DEG F. and the stoving temperature 350 DEG F.  All the enamels may contain a cellulose ester or ether, and alternative fillers are quartz, silica, bentonite, barium sulphate, stannic oxide and chromium oxide.

Title: A station for seam welding continuously delivered metal tubes
IPC: B23K15/00
Filed: 1969-01-23
Abstract: 1,261,551. Welding by fusion; making  longitudinally seamed tubes. VALLOUREC USINES A TUBES DE LORRAINE-ESCAUT ET VALLOUREC REUNIES. 23 Jan., 1969 [23 Jan., 1968], No. 3779/69. Headings B3A and B3R. [Also in Division H1] In electron beam longitudinal beam welding of continuously delivered steel, particularly alloy or stainless, tube 1, an electron gun 2<SP>1</SP> is connected to a housing 8 connected to a main evacuating pump 11 and extended upstream and downstream by sleeves 9, 10 the lengths of which co-operate with means near the sleeve ends to maintain partial vacuum in the housing. The welding is effected at a station preceded by stations (not shown) converting a continuously delivered strip into a circular cross-section tube 1. Rollers 2 co-operate with a fixed or displaceable blade 2a to open up the tube for admission of a rod or tube 23 (Fig. 2). Rollers 12 cooperate with a blade 13 for aligning the tubeforming strip edges with the electron gun, and rollers 14, 15 respectively close the tube and nip the edges together before and after welding. Seals 24, 25 (Fig. 2), e.g. of plastics such as P.T.F.E., are provided in contact with the inner surface of the tube 1 upstream and downstream of the housing and may be carried by the rod or tube 23 which may carry a tool 22 for scraping or flattening the weld bead. The seal 24 may have an outwardly projecting longitudinal rib to close the opening provided by the blade 2a. Seal-efficiency-increasing, low vapour pressure, liquid may be fed, through a tube 26 incorporated in the rod or tube 23, to the upstream side of the seal 25. The rod may also be used to connect an additional pump to the tube 1 interior for evacuation thereof. To protect the lower inside surface of the tube 1, and the rod or tube 23, against the effect of the electron beam, the rod or tube 23 is either in part formed by (Fig. 3A, not shown), or carries in a nacelle (Fig. 3B, not shown), refractory material such as a molybdenum bar positioned in the beam path. The refractory material may be cooled by circulating water. Preferably, chambers 18, 19 provided near the ends of the housing sleeves are gently evacuated by pumps 16, 17 (e.g. vane pumps), and, in addition, mechanical, hydraulic or pneumatic sleeve/tube seals 20, 21 are provided at the tube ends. Other pumps, such as 16, 17, may be provided in the vicinity of the housing 8, and two pumps, such as 11, may be provided on either side of the beam. An annular pump may be arranged, at the position 20, to blow a liquid screen tangentially on to the tube to provide a seal. Constant vacuum may be maintained in the welding zone by an auxiliary pressure adjustment pump 11<SP>1</SP> controlled by means 11<SP>11</SP> responsive to welding zone vacuum. The tube 1 is preferably preheated as by deformation of the electron beam, by an additional electron gun 30, or by medium- or radio-frequency induction coils 31 arranged before the blade 13 or, as shown, the gun 2<SP>1</SP>, a screen being preferably provided to protect the electronic lenses.

Title: Improvements in or relating to the counting of electrical impulses
IPC: G06F7/40
Filed: 1945-02-15
Abstract: 588,402. Electric counters. GUNNING, P. F. Feb. 15, 1945, No. 3878. [Class 106 (i)] An impulse counter employing electromagnetic relays comprises a chain of relays which register the total in successive powers of two and a corresponding chain of steering relays of which only one at a time is energized for the duration of an impulse. The arrangement may be adapted also for subtraction from the total by the use of a further chain of steering relays or by the use of registering relays ef a particular type. In Fig. 2, the chain of registering relays 1A, 2A ... are controlled by a chain of steering relays 1B, 2B ... for impulses to be added and by a second chain of steering relays 1C, 2C ... for impulses to be subtracted. In the case of addition, the first impulse operates 1B which locks in series with GU for the duration of the impulse and connects up 1A which locks. The second impulse operates 2B which connects up 2A and releases 1A, so that the third impulse operates 1B, 1A without affecting 2A. The fourth impulse, since 1A, 2A are both up, operates 3B which connects up 3A and releases 2A, 1A. Thus the operation of any relay of the B chain causes the operation of the corresponding relay of the A chain and the release of all the earlier relays of that chain. In the case of subtraction, the operation of a relay of the C chain produces a reverse effect. Assuming that 4A alone is operated in the A chain, an impulse to be subtracted energizes 4C which releases 4A and locks in series with GU for the duration of the impulse, and GU connects up 1A, 2A, 3A, which lock. A second impulse to be subtracted energizes 1C, which. releases 1A. This arrangement may be modified by the use of two-step relays. In Fig. 4, each of the register-. ing relays 1A, 2A ... is of the magnetic locking type disclosed in Specification 515,529, [Group XXXVII], in which the relay operates on current in one direction in either winding, restores on current in the other direction and maintains the existing position when current ceases. This enables a single chain of steering relays 1B, 2B ... to be used for addition and subtraction, the direction of current in relays 1A, 2A ... being varied according to the operation to be performed.
