Title: Weighing machines
Inventor: JONES BRIAN HAROLD
IPC: B07C5/20
Filed: 1957-10-11
Abstract: 883,589. Weighing apparatus. SPERRY GYROSCOPE CO. Ltd. Oct. 1, 1958 [Oct. 11, 1957], No. 31897/57. Class 143. In a check weigher wherein the weighing unit comprises a float 1 buoyantly supported in a liquid in a container 2 and carrying a commodity bucket 4 or the like, movement of the bucket 4 in response to the arrival thereon of an article dropped from a feed conveyer 5 is restricted to a predetermined distance by a stop 6, and means 9 responsive to arrival of the bucket at the stop 6 initiates release of the stop 6 to permit the weighing operation. As shown the stop 6 is guided for vertical movement in guides 7 and is actuated by a cam 8 driven through a single-revolution clutch 10 by a motor 11. The stop 6 limits depression of the bucket 4 under the action of an article dropped therein to an amount sufficient only to close a mercury switch 9 on the stop 6 and thereby actuate the clutch 10 to rotate the cam 8. Rotation of the cam lowers the stop 6 for a time sufficient to complete the weighing operation before rotation is completed and the stop 6 returned to its normal position ready for the next weighing cycle. A discharge pusher 12 is operated on return of the stop 6 to eject the weighed article into an "accept" or "reject" channel selected according to the weight of the weighed article. Specification 633,075 is referred to.

Title: Improvements in or relating to bumper bars for motor vehicles
IPC: B60R19/28
Filed: 1926-12-17
Abstract: 280,390. Cheshire, F. B., and Ladbroke Plating Works, Ltd. Dec, 17, 1926. Collision-guards.-A spring bumper or fender for use on a motor-vehicle comprises a resilient fender bar a which is bowed under tension and permanently held under tension, e.g. by connection to a rear tension bar b, and is supported in such a way that, when pressure is applied to it from the front, it tends and is permitted to straighten or flatten out. In the construction shown the ends a<1> of the fender bar are connected at the points c to the ends b<1> of the bar b, which are bent rearwardly so that the actual distance between the points c on the two sides is less than the length of the bar b between these points. Thus, when an obstacle is encountered, the initial shock is mainly taken up by the tension bar but continued pressure causes the fender bar to straighten out as shown in Fig. 4, the ends of the tension bar also straightening out to compensate for the increase in width of the fender bar. Strong steel plates or brackets d are used to connect the tension bar to the vehicle chassis. In a modification, Fig. 6, a spring f is disposed between the fender and tension bars to damp any vibrations arising in the fender bar, and the fender bar is constructed of two spring members a<2>, a<3>. The fender bar may be constituted by a laminated spring, while the tension bar may also be in multiple form or consist of a laminated spring.

Title: Improvements in textile filament production
Inventor: SCRAGG FREDERICK
IPC: D01D5/00
Filed: 1961-09-06
Abstract: 950,524. Branched filaments. ERNEST SCRAGG & SONS Ltd. Aug. 31, 1962 [Sept. 6, 1961], No. 32008/61. Heading B5B. [Also in Division D1] The branched filaments moulded or cast from organic thermoplastic material as disclosed in Specification 924,517, are treated by bending the branches or side hairs in a direction substantially parallel with the axis of the trunk of the filament, and drawing the filament. The bending step is carried out by passing the filament through a condenser, e.g. a tube surrounding the filament and decreasing in diameter in the direction of travel of the filament. The drawing is preferably carried out by passing the filament between two pairs of nip rolls, the second pair rotating at higher peripheral speed than the first pair, which is preferably heated. Subsequent to drawing, the branches of the filament may be brushed up. The process may be applied simultaneously to a large number of filaments, the filaments being combined e.g. by means of a low twist, before or after drawing to form a multifilament yarn. In one embodiment (Fig. 1), a roll 11 of untreated filament 12 (Fig. 3) passes through a condenser 26, which aligns the side-hairs parallel to the axis of the main trunk, then through heated nip rolls 13, 14 to nip rolls 15, 16 rotating at higher peripheral speed to draw the filament. Since both the trunk of the filament and the branches are aligned in the direction of travel, both the trunk and branches are fully drawn (Fig. 4).

Filed: 1934-11-08
Abstract: Salts of ethereal sulphates are prepared by reacting a long chain alcohol having 10 to 20 carbon atoms with 100 per cent sulphuric acid, fuming sulphuric acid or chlorosulphonic acid at a temperature within the range of 0 to 50 DEG  C. and thereafter neutralizing with a suitable base.  In addition to single alcohols, mixtures such as those produced by the catalytic dehydrogenation of cotton seed oil, palm kernel oil, olive oil, coconut oil, and various fats can be employed, for example, the mixture of lauryl, myristyl, cetyl, and stearyl alcohols obtained from coconut oil catalytically, or the mixed oleyl-stearyl alcohols obtained by the saponification of sperm oil.  Esters obtained from hexyl, octyl, decyl and ricinoleyl alcohols are also mentioned.ALSO:In the moulding of plastic compositions especially of natural, synthetic, and artificial rubber, adherence of the composition to the mould is prevented by the presence between the contacting surfaces of the mould and moulding composition of a salt of a polybasic acid which has been partially esterified with a saturated or unsaturated alcohol of the aliphatic series having 6 to 20 carbon atoms, or a mixture of such salts.  The alkali metal salts, especially the sodium salts, are particularly suitable, but ammonium and amine salts can be used also.  The sulphate ester salts may be prepared by reacting a long chain alcohol having 10 to 20 carbon atoms with 100 per cent sulphuric acid or fuming sulphuric acid or chlorosulphonic acid at a temperature within the range of 0 to 50 DEG  C., and thereafter neutralizing with a suitable base.  In addition to single alcohols, mixtures such as those produced by the catalytic dehydrogenation of cottonseed oil, palm kernel oil, olive oil, coconut oil, and various fats can be employed, for example, the mixture of lauryl, myristyl, cetyl, and stearyl alcohols obtained from coconut oil, catalytically, or the mixed oleyl-stearyl alcohols obtained by the saponification of sperm oil.  Esters obtained from hexyl, octyl, decyl and ricinoleyl alcohols are also mentioned.  The polybasic inorganic or organic acids which can be used for the esterification include, in addition to sulphuric acid, phosphoric, oxalic, tartaric, citric, phthalic, and lauric acids.  Water or alcoholic solutions of the salts may be used, or the salt may be deposited on talc or other dry material base and applied as a dust.  An example is given.

Abstract: 354,126. Cigarette-making machines. H€NDEL, L., 8, Niddastrasse, Dresden, and ATLAS-WERKE POHLER & CO., 64, Schonbachstrasse, Stotteritz, Leipsic, both in Germany. Oct. 29, 1930, No. 32544. Convention date, Oct. 29, 1929. [Class 130.] All-tobacco cigarettes are produced by cutting lengths from a continuous strand, the lengths being compressed endwise to avoid the necessity for trimming, and then transferred to boxes each containing a nest of rollers which apply the wrapper of tobacco leaf. The severed lengths are received by tubes-3 resting on trays 6 carried by an intermittently rotating disc 4. The tubes may be in one piece, conically bored, or divided, the opposing halves being mounted on a spring member 8 which separates the halves when they are moved to the flared outer end of the trav. While within the tube the opposite ends of the tobacco length are compressed by plungers having concave ends. The tube is then carried lengthwise by a rod 18 engaging upstanding lugs 7. The tobacco length is prevented by a fixed abutment from returning with the tube, and falls into one of a series of boxes arranged around a rotatable disc 20. The next movement of the disc 20 closes the lid on the box and a tobacco wrapper, supplied with adhesive, which has been placed on the projecting table 27 is then drawn in by the rollers 23 which are rotated through toothed gearing and a friction wheel 25 engaging a fixed track in the framing. Rollers are situated at each end of the tobacco length within the box 20, one of the rollers being periodically pressed inwards by a cam surface on the adjoining frame. As each box-lid becomes free from the restraining cam path 40, it is opened by the spring 35, and the enclosed cigarette drops into a recess on a conveyer 37. During the forward movement of the latter the complementary shaping member 38 is applied and the finished cigarette is discharged into a box &c.
