Abstract: 230,209. Norfolk, T. L. Jan. 5, 1924. Tipping-apparatus; staiths.-A mechanicallyactuated spade member 9 is mounted on the staith for loosening and dislodging moist coal, ashes, ballast &c. from a wagon 5 when tilted to any angle on the tipping platform 4. The spade 9 is carried by a strut 6 which is raised and lowered by rack-and-pinion or other gearing. The strut 6 is turned about the axis 10 by a second strut 8 which is moved longitudinally in guides in the supporting frame 16 by rack-and-pinion or other gearing. The two struts are pivotally connected at 19, and the pivot is free to slide in guides 20 on the strut 6. The frame 16 is adjustable vertically on the structure 1. The members 6 and 8 are operated either by separate motors with independent controls, or by a single motor driving through separate clutches. The spade is moved so as to dig or slice into the contents of the wagon, and then to move along the wagon, the movements being repeated from positions successivelv nearer the back of the truck. The limiting positions of the spade are shown at 25, 26. The weight of the spade mechanism and framework 16 may be counterbalanced.

Title: Hydraulic brake mechanism
IPC: B60T11/228
Filed: 1950-01-06
Abstract: 677,463. Hydraulic brakes. BARBISAN, A. Jan. G, 1950 [Jan. 26, 1949], No. 435/50. Class 103 (i). A hydraulic brake system for motor vehicles comprising a master-cylinder piston 4 and an auxiliary piston 9 for maintaining the liquid under pressure is characterized in that the auxiliary piston 9 is mounted loosely on the rod 5 of the main piston 4 and is acted on by a spring 10 to maintain under pressure the liquid in the space 7a between auxiliary piston 9 and cylinder end, which space communicates with the braking circuit by conduits 21, 21a, when the main piston 4 is in its rear position, means actuated through the normal movement of the brake pedal being provided for returning the auxiliary piston to its initial position each time it reaches the end of its travel on the rod 5 due to reduction of volume of liquid in the brake circuit. In the arrangement according to Figs. 2 and 4 leakage of liquid causes the auxiliary piston 9 to move to the right and, when near the end of the master cylinder 3, grooves 22 in the cylinder wall put the space 7a into communication with the reservoir 2, the spring 10 forcing the end of the piston 9 against a number of balls 16 in a cage 17, with the result that upon the next working stroke of the main piston 4 a circumferential groove 19 in the rod 5 engages the balls 16 to move the auxiliary piston 9 to the left and fill the space 7a with liquid from the reservoir 2. At the end of the working stroke a weak spring 18 returns the balls 16 and cage 17 to the end of the master cylinder. In the arrangement according to Fig. 6 the auxiliary piston 9 is locked to the piston-rod 5 by a spring-loaded pawl 23, while in the further embodiment shown in Fig. 8 a spring catch 33 is provided for this purpose. A spring-loaded diaphragm, Fig. 10 (not shown), subjected to the pressure of the liquid in the braking circuit may operate an indicator when the pressure falls below a predetermined value.

Title: Improvements in or relating to glass container manufacture
IPC: C03B23/09
Filed: 1959-01-07
Abstract: 849,617. Infra-red control arrangements. KALMAN, P. G. Jan. 7, 1959, No. 632/59. Class 40(3). [Also in Groups XXII, XXIII and XXX]  In the formation of ampoules or like containers from tubular glass blanks, the heating of the rotating blanks, prior to the forming and rolling of the necks, is electronically closely controlled so as to bring the blank to a desired temperature. Heating before each stage is affected by a pair or more of burners with a temperature sensitive element between the or each pair and an error signal relating to the deviation of temperature of the blank from that required is amplified and a solenoid valve used to alter the fuel mixture of the burner following the element. As shown in Fig. 19, an infra-red radiation detector D such as a vacuum thermopile or a photoconductor has a suitable filter F to restrict the radiation to an equivalent wavelength range between 5 and 12 microns from the hot blank B. The detector D is connected by a three resistance bridge circuit BR energized by alternating current supply ST and an error signal therefrom is amplified at A and passed to a timing circuit T which controls a solenoid valve SV which will affect, normally enrich, the fuel to the next burner BU. A preferred form of the timing circuit is given in detail.

Abstract: 264,181. Soc. Lyonnaise de Soie Artificielle, and Chevalet, P. A. A. Jan. 11, 1926, [Convention date]. Cellulose acetates; preparatory treatment of cellulose.-Cellulose is rendered active and capable of producing acetates giving viscous solutions by treatment at ordinary temperature or in the cold, with 80-90 per cent formic acid to which has been added sulphuric acid or zinc chloride in proportion less than 10 per cent of the whole mixture. This treatment avoids depolymerization of the cellulose molecule. The bath may be prepared by treating sodium formate with sulphuric acid. After treatment with the acid, the excess of the latter is removed, and the product is washed and dried. When using cellulose which has been pretreated in this manner, only traces of sulphuric acid are required to effect acetylation. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of 100 per cent formic acid without any addition. This subjectmatter does not appear in the Specification as accepted.
