Abstract: 511,881. Sound deadening; walls. TUG WOOD, R. J. (Daimler-Benz Akt.-Ges.). April 20, 1938, No. 11839. [Classes 20 (ii) and 20 (iv)] [Also in Group XXVII] The walls of testing stations for internal combustion engines are formed with irregular distributed chambers in their structures which communicate with the outside air by means of perforations through the bricks. Air is supplied through a chimney 18 to an air tunnel A in which is mounted the engine on test on a resilient bed 20, 21 and the air is exhausted through guide vanes 17 to another chimney 16. The sound is damped in the roof of the wind tunnel by a system of lathing 26 spaced from the ceiling, the spacing between the laths decreasing from the centre towards the supply and exhaust chimney. Each wall section is formed with honeycomb bricks 24, the perforations in the bricks placing the air in the tunnel in communication with unsymmetrically disposed spaces such as 23, formed inside the wall structure, wherein the noise is deadened. In a modification as shown in Fig. 9, the honeycomb bricks are laid'together with mortar disposed only at their corners, so that tortuous paths through the wall section serve to deaden the noise. Where two testing stations or a testing station and an instrument room are separated by a common wall, this wall is formed double as shown in Fig. 6, with an intervening hollow 28 between the wall sections, each wall section being also provided interiorly with the unsymmetrically disposed sound deadening cavities.

Title: Improvements in sheet feeding devices
IPC: B65H3/46
Filed: 1942-09-02
Abstract: 559,822. Feeding sheets. KAUFFELD, T. J. Sept. 2, 1942, No. 12409. Convention date, Sept. 16, 1941. [Class 100 (i)] An overlapping stream feed apparatus which is similar to that described in Specification 559,821 is constructed with means for separating the sheets from a pile P and advancing them in overlapped condition to tapes 30 consisting of a main friction roller 70 which is carried in a pivoted frame oscillated about a hollow shaft 16 by a cam mounted on a shaft 15 both shafts being mounted in a carriage adjustable fore-and-aft of the pile for dealing with sheets of different lengths. The roller 70 co-operates with a stop 58, which is also moved into and out of contact with the pile by cam mechanism, to cause the top sheet to buckle, and the stop is lifted before the roller 70 so that the buckled sheet is released and caused by the roller 70 to pass into contact with the tapes 30 and feed rollers 35, pile stops 38 being oscillated out of the way of the separated sheet if such stops are used. Before the separated sheet is completely removed from the pile the stop 58 and roller 70 act upon the succeeding sheet so that the sheets advance in overlapped condition. To ensure ready separation of the sheets, the edges of the sheets are acted upon by combing rollers 88 arranged diagonally at each rear corner of the pile, the rollers 88 being mounted in oscillating frames 85 and driven by bevel gearing 89, 90 and gears 93, 91 from the shaft 15. The shaft 16 may be formed with apertures from which blasts of air are blown upon the buckled sheet to smooth it out and assist in its advancement. The blast may be delivered intermittently or continuously. The carriage of the feed devices is adjustable by means of gears 23, 24 engaging fixed racks 18, 19, and a gear box' 12 in which the main shaft 15 is mounted forms part of the carriage. The shaft 15 is driven from a bevel wheel splined to a shaft driven by bevel gearing from a shaft in a gear box 34, the shaft being driven by gears from the machine to which the sheets are fed. The invention may be applied to sheet feeding apparatus other than overlapping feeds.

Title: A process for improving the dyeing properties of viscose silk
IPC: D06M11/62
Filed: 1929-04-22
Abstract: 331,612. Johnson, J. Y., (I. G. Farbenindustrie. Akt.-Ges.). April 22, 1929. Yarns &c., treating with liquids.-The lustre and dyeing properties of viscose silk are improved by treating freshly finished viscose silk of any kind while still in the wet state with ammoniacal copper oxide solutions free from caustic alkali, and containing up to 0.3 per cent of copper, until a small percentage of the dry weight of the viscose silk has dissolved. In the case of viscose silk having orientation of the cellulose micellae the process may be carried out after the initial drying. The threads may be treated on spools directly after spinning, stretching, and acid treatment, with the ammoniacal copper oxide solution which may contain other ingredients such as dissolved cellulose but no free caustic alkali. The strength of the copper solution is varied within the limits claimed according to the particular viscose silk to be treated and adjusted so that only a few per cent of the silk are dissolved. The concentration is preferably chosen so that the treatment does not exceed 1 hour. The threads are afterwards treated with dilute acid. The treated viscose silk has a silky lustre, is microscopically roughened so that slipping of the threads is reduced, and can be dyed more evenly and in stronger shades than untreated viscose silk. In examples " Agfa Seide " or " Agfa Travis " silk is washed immediately after spinning and treated before or after desulphurizing, on spools at room temperature with ammoniacal copper oxide solution containing 0.2 to 0.3 per cent of copper and 4 to 6 per cent of ammonia for half an hour. The spools are washed with dilute sulphuric acid, and with water. In other examples viscose silk prepared according to Specification 274,521, [Class 2 (ii), Cellulose &c.], is treated for 8 minutes with a solution containing 1.5 grams of copper and 50 grams of ammonia per litre, or for 1 minute with a solution containing 3 grams of copper and 50 grams of ammonia per litre. The silk is washed with dilute sulphuric acid and with water. In the Provisional Specification an example is given in which the strength of the ammoniacal copper oxide exceeds 0.3 per cent of copper.

Filed: 1973-03-15
Abstract: 1428163 Braking of hand-propelled vehicles A MANSS 15 March 1973 [25 March 1972] 12604/73 Heading F2E A luggage truck has a tubular pushing frame (1), 6 inside which extend vertical brake rods 5 carrying brake shoes 9 actuatable on wheels 8 to brake the truck and hold it stationary, the rods 5 being arranged to extend substantially perpendicularly to the axis of rotation of the wheels. As shown, the wheel 8 has a trapezoidal profile with a contact surface 12 and oblique edge strips 11, and the brake shoe 9 also has a trapezoidal shape. Advantageously the angle (α) between surface 12 and strips (11) of wheel 8 is a little larger than the angle (α<SP>1</SP>) between base and side of brake shoe 9 so that on setting down the shoe 9 on the wheel 8 by vertical movement of rod 5 the shoe is pulled by continuing movement of the wheel from linear contact to areal contact to amplify the braking effect, the brake profile having a certain elasticity. A weak spring may aid brake application. In another embodiment the shoe engages from one side at the edge surface of the wheel, the brake shoe having a smaller angle with respect to the wheel plane than the wheel surface. In another embodiment the brake shoe has an arcuate profile of smaller radius than the wheel profile.

Abstract: 403,001. Photographic printing-apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. May 1, 1933, No. 12633. Convention date, Feb. 7. [Class 98 (ii).] In a process of printing designs on textile piece goods employing light-sensitive e.g. diazotype, materials, a discharge tube is used having an incandescent cathode, the energy distribution of the tube being such that the energy of wave-lengths shorter than 2700 Š is less than 10 per cent of that of wave-lengths between 2700 Š and 5000 A. The filling of the tube may be a gas, such as cyanogen or helium, or the vapour of a metal, e.g. zinc, thallium, mercury, magnesium, cadmium, bismuth, or antimony. In the case of mercury, radiation of wavelength 2537 A is preferably absorbed before reaching the sensitive material. The process may be carried out with a rotary negative over which the sensitive material is fed, or with a plane negative along which the material is fed in steps. In the form shown, the tube 9 is arranged at the axis of a drum-shaped negative 10 over which the material passes, a screen 14 being provided to shield the material from the light except when in contact with the negative. The shield 14 may be constructed as a reflector. The tube consists of a glass vessel with incandescent cathodes and anodes sealed in at opposite ends.
