Title: A method and apparatus for producing a metal article
Inventor: HIGGINBOTHAM GORDON JOHN SPENC
IPC: B22D5/02
Filed: 1969-07-11
Abstract: 1,269,833. Crystallising. ROLLS-ROYCE Ltd. 30 June, 1970 [11 July, 1969], No. 35121/ 69. Heading B1S. [Also in Divisions B3 and F4] Articles are directionally solidified by effecting relative movement between an article-containing mould and a furnace having a heatfront therein. A mould 17 for a turbine blade is placed on a water-cooled chill plate 16 on a continuously or indexably rotating table 12. A furnace 13 extends about part of the circumference of the table 12 and includes a mould preheating zone A, a pouring station B and a solidification zone C. Heating elements 15 extends along the sidewalls 14a, 14b (and, if desired, the roof) of the furnace. The length of the elements 15 in the solidification zone increases from the pouring station B through the zone C in the clockwise direction P. In operation the table 12 rotates clockwise sequentially preheating the moulds 17, filling them with a molten charge at B and cooling the charge from its base upwards as the moulds pass through the zone C having a heat-front at an oblique angle to the table 12, the angle being determined by the diminishing length of elements 15 in the clockwise direction. As an alternative, a particulate or rough cast article can be placed in a mould and melted as it passes through the furnace. Vacuum or inert atmospheres can be provided within the furnace and multicavitied moulds may be employed.

Abstract: 1,196,737. Hydraulic steering systems for vehicles. PLESSEY CO. Ltd. 4 Aug., 1967 [10 Aug., 1966], No. 35880/66. Heading B7H. An hydraulic steering system for vehicles comprises a rotary-vane master pump A e.g. as described in Specification 1,190,768, connected to a slave cylinder L (whose piston is connected to steering linkage) via a control valve comprising a bored piston M, which is spring- urged to a central position, wherein a fixeddisplacement power-assistance pump X freely supplies liquid via ports R, Q, Q 1  and line T to the tank J, but which is moved (thus closing ports Q or Q 1 ) by the pressure created by the pump A in chamber C or E so as to deliver the pressure liquid from the pump X via port R, bore Z, non-return valves CC or EE and chamber C or E to the lower pressure side of the master pump A to assist the torque applied thereto by the steering wheel B (or its equivalent) and 80 as to disconnect the lower pressure side of the slave cylinder L from the pump A (by blocking bore D 1  or F 1 ) and connect it via ports D or F and Q or Q 1  to the tank J. Thus the pressure difference in the slave cylinder L is equal to the sum of the manually produced pressure in master pump A and the pressure supplied by the pump X to the lower-pressure side of the master pump A. The vehicle steers itself when being towed. Failure of the pump X or its delivery line does not interfere with manual operation of the system. In Fig. 2, a single pre-loaded spring N 2  urges the piston M to a central position, and each vane A 1  of the master pump A is urged by a spring A 2  against its housing.

Title: Combination selector for addressing and like machines
IPC: B41L47/58
Filed: 1946-12-12
Abstract: 627,732. Addressing machines. MERCER, R. (Berglind, G.). Dec. 12, 1946, No. 36765. [Class 100 (ii)] In a combination selector for addressing and like machines in which the printing operation is controlled by electrical circuits operated from impulses set up by feeling members B responding to various characteristics on printing plates or other members fed through the machine, the control circuits are arranged in separate groups comprising at least one group of make contacts and one group of break contacts. The circuits can be connected up so that both the presence of a certain signal or combination of signals, and the absence of a certain other signal or combination of signals may be made conditions to effect the machine operations. As shown in Fig. 1, A represents a printing plate 1 having signals 1p ... 3p in the form of bosses, tappets, riders or holes which open contacts in a group, 1b ... 3b, and close contacts in a group, 1s ... 3s, all connected to a switching plinth C upon which flexible connections can be made so that various circuits are set up to operate a relay control device D controlling the operations of the printing machine. The relay device D comprises a relay 10 upon whose operation activates the printing machine, a relay 8 having break contacts 9 in an operating circuit of the relay 10, and a transformer 3. Figs. 2 to 6 (not shown), illustrate circuits utilising the make contacts only for dealing 'with certain combinations of tabs. In the example of connections shown, Fig. 7, the printing operation is dependent not only on the presence of codes 3, 4, but on the absence of signals 1, 2, 5, printing taking place also if signals 1, 2, 3, 5 are present with the simultaneous absence of signal 4. Fig. 8 (not shown), gives the connections for the selection of a group of six codes by a process of excluding the unwanted codes, utilising the break contacts bk and the printing suppressing relay 8. The contacts may be actuated by mechanical, electro-mechanical, or photo-electrical devices. A modification is described using one group of break contacts and two groups of make contacts giving further permutations.
