Abstract: 421,550. Locks. DUDSON, T., 42, High Street, Abertridwr, near Cardiff. June 21, 1933, No. 17655. [Class 44] [See also Group XXXI] A locking device, particularly for a motor car steering- wheel, consists of a barrel 1 having bores 3 to house screwed spindles 12 which carry at their lower ends locking elements in the form of mutilated discs 14 which are rotated so as to lie flush with the surface of the barrel by depressing nuts 10 against springs 13 by means of a key. To allow the combination of the lock to be changed, each spindle carries a pinion which engages with a corresponding aperture in the disc 14, the latter being retained on the spindle by a nut 19. Graduations are provided on the disc and one of the teeth of the pinion may be omitted to form a pointer. To allow access to the discs for adjustment, the barrel is provided with a detachable cap 8. Opposite pairs of discs are arranged at different levels so as to be clear of one another. In one form, Figs. 1 and 7, the key shank 21 is provided with graduations 25 adjacent to slots 23, and threaded bores extending into the slots house adjustable screwed plugs 24 which when the key is inserted into a bore 7 in the barrel engage with projections 11 to depress the nuts 10 and thus free the barrel. The bore 7 may be of any cross-section to ensure the correct orientation of the key. In another form, the key, Fig. 8, has graduated tubes 28 slidably mounted in bores in the body part 27 and held in adjusted position by screws 30 engaging with holes 29, the tubes being adapted to engage directly with the tops of the nuts and over the screwed spindles. As applied to a motor car steering- wheel, the barrel 1 is mounted in the top of the column and the discs 14 engage with recesses in the outer fixed member, the wheel being free when the key is in the lock ; the key is retained in the lock by a suitable catch. The barrel may be completely removable from the column or it may be provided with a projection 32 which co-operates with a slot in the column to allow the barrel limited movement and to hold it raised by engagement with a recess.

Title: Improvements relating to electrical driving of machines, or other apparatus or shafting
IPC: D03D51/00
Filed: 1929-06-08
Abstract: 333,337. Ross, H. R., and Cunning- ham, R. June 8, 1929. Driving -arrangements.-An electric motor for individual driving in warping machines or other apparatus by friction gear is slidably supported in such a manner that its driving-pulley is brought into contact with the frictionally driven wheel in the machine when the motor is moved in one direction and into contact with a reverse wheel in the machine when the motor is moved laterally in the other direction. In the intermediate position there is no drive, and when the motor is applied to a warping machine the lever or the like which moves the motor may also control the usual drop bars motion of the machine for tensioning the warp threads. The Figures show the application to a warping machine wherein the motor 1 is moved on its platform by a hand lever 6 so as to bring its friction pulley 2 either into direct contact with (i) the wheel 3 on the spindle 4<a> which drives the warp roller 4<c>, or (ii) an intermediate friction reduction gear 7, 8 to give a reversed drive to the spindle. This reduction gear is pivotally mounted in a bracket 7<b> so that it is raised into driving contact with the wheel 3 when the motor is moved to the right. The gate 9 has three positions for the lever 6 corresponding to forward, reverse, and neutral drives. In the reverse position, studs 10<a> in a plate 10 operated by the lever 6 engage an arm 10<b> on a vertical spindle 10e, the lower end of which is coupled by a quadrant rack to a sliding bar in the machine frame. This bar is coupled at its other end by a second quadrant rack to a vertical spindle 10<d> at the other side of the machine, and the rotation of the two spindles causes pins 14 to move the slippers 15 horizontally and so lower the drop bars 16 slowly in succession to take up the slack in the warp as it occurs. When the lever 6 is moved to give forward drive the drop bars are successively raised.

In a continuous casting plant, Figs. 1 and 2 (not shown), in which molten metal cast in a vertical mould is withdrawn from the mould along an arcuate path leading to a horizontal path, means in the form of driven rolls are located at the lower end of the arcuate path to effect the casting withdrawal. The withdrawal rolls (77), Fig. 11 (not shown), are incorporated in a levelling unit (32) which effects straightening of the cast bar into the horizontal path. Rollers (14) support the casting as it leaves the mould and a plurability of guide rollers (15) are located around the arcuate path and are carried in three groups in frames (19), (20) and (21), Fig. 3 (not shown). The guide roll sections are adjustable to accommodate castings of different sections and each guide roll frame has means associated therewith for cooling the casting. Further cooling is applied to the casting at the end of the guide roll sections, in which steam or compressed air is directed on to the casting, in opposition to its movement, by nozzles (26) and baffles (27). A starter bar is used at the commencement of the casting operation, the bar being composed of flexible links and means are provided for removing sections of the starter bar when it has passed through the guiding and withdrawal units. Two alternative starter bar removal means are desembled, the first Figs. 4 and 5 (not shown), including arms which pivot about an axis parallel to that of the bar and are adapted to raise the bar out of the path of the casting and in the second a framework, Fig. 10 (not shown), which supports vertical movable platforms which are adapted to raise given sections of the bar clear of the casting. Also, in an alternative embodiment the support rolls (14) beneath the mould may be replaced by a removable frame which carries the rolls, Fig. 9 (not shown), to facilitate ease of access for maintenance.

Title: Process for the production of cellulose conversion products
IPC: C08B15/00
Filed: 1923-07-09
Abstract: Cellulose conversion products in the form of solutions, pastes or doughs are obtained by treating cellulosic bodies with strong sulphuric acid at a temperature not below \sw9 DEG  C. and not above 4 DEG  C., preferably between \sw5 DEG  C. and 5 DEG  C., for example, between \sw2 DEG  C. and 9 DEG  C.; the proportions of acid particularly suitable are not more than 6 parts and not less than 1.5 parts of sulpuric acid monohydrate, for example, not more than 4 parts and not less than 2 parts, for each part of air-dried cellulosic material.  To separate the products, the solution, dough or paste is mixed with a precipitating-agent such as snow, ground ice, ice-water, dilute acid preferably intensely cooled, a cooled salt solution, a solution of acetic acid or benzenesulphonic acid or phenolsulphonic acid or other organic acid, or a solution of an alcohol; the product is washed and if desired, dried, and is brought into a form for technical use by solution in caustic alkali, such solution being conducted according to the character of the initial cellulose material and the conditions of the preceding treatment, either at room temperatures or at lower temperatures, for example, at \sw5 DEG  C. to \sw12 DEG  C., such lower temperatures being useful in effecting solution in cases where the action of the sulphuric acid has not proceeded to a great extent. The solutions in caustic alkali may be used in the manufacture of artificial silk, &c., artificial hair, films, plastic masses, coatings, finishings, sizes, artificial leather, &c.  As the initial material there may be used, bleached or unbleached cellulose of any kind, products obtained by the mechanical comminution of cellulose in the presence of water, products obtained by treating cellulose with reducing or oxidizing agents, products obtained by heating cellulose alone or with water, glycerine, or salts; products resulting from the treatment of cellulose with hot or cold alkalies with or without subsequent treatment with dilute acids and with or without previous or subsequent treatment with oxidizing or reducing agents; the cellulose hydrates obtained by precipitating solutions of cellulose in cuprammonia or zinc chloride solutions; artificial silk, &c., hydrocellulose, oxycelluloses, and the products obtained by treating cellulose with strong acids, cuprammonia or zinc chloride solutions, to a point short of dissolution.  In examples, sulphuric acid of 60 DEG  B<\>ae is employed, and the acid is precooled before the addition of the cellulose to a temperature lower than that at which the reaction is conducted; the cellulose may be dried and cooled before addition to the acid. Specification 212,864 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) includes the employment of temperatures up to but not above 6 DEG  C. This subject-matter does not appear in the Specification as accepted.
