Title: Improvements relating to cam-operated copy-turning apparatus
Inventor: BENNETT RONALD
IPC: B23Q35/18
Filed: 1957-01-21
Abstract: 864,643. Copying-lathes. ROLLS-ROYCE Ltd. April 18, 1958 [Jan. 21, 1957], No. 2204/57. Addition to 749,006. Class 83 (3). The apparatus described in the parent Specification is modified in that the cam and follower means for producing the root or shroud portion of a turbine blade operate through an hydraulic servo or copying means instead of directly. A diagrammatic representation, Fig. 1, shows the tool 25 arranged for a transverse first movement on a longitudinally movable member 50. The latter is secured to a piston 51 moving inside a cylinder 52 which is formed with a piston land 53 and is itself slidable within a stationary cylinder 55. The first piston is traversed by releasing, with each revolution of the work, a predetermined volume of liquid from the L.H. side of piston 51 by a cam-operated valve. The second piston 53 is supplied with liquid through passages 106, 107, from a control valve 57, secured to the longitudinally moving parts, and operated by cam-and-lever mechanism 58 from a cam 36 which replaces the cam used in the main apparatus. Piston 53 thus provides the movement for turning the blade root or shroud portion. Since the cam 36 takes very little load it may be made from synthetic resin or other plastic material. The transverse movement of the tool may also be effected by an hydraulic copying device.

Abstract: 284,287. K³chenmeister, H. J. Jan. 27, 1927, [Convention date]. Optical apparatus. - In apparatus for reproducing sound photo - electrically from a film record, two or more sources of light are. used, from which light is transmitted by means such as mirrors and condensing lenses through the part of the record where sound-reproduction is effected. By this means, if one source of light fails whilst the apparatus is in operation, the sound-reproduction is not completely interrupted. The sources of light may all be arranged upon a common support. Means may also be provided for enabling a source of light that has failed to bn readily replaced by a new one. For this purpose, an incandescent lamp with two or more independent filaments may be used. In the apparatus shown in Fig. 1, two lamps b, c are arranged, with a reflector d behind them, in a roller a over which the film f is guided. Light from the lamps is transmitted through the film to a selenium cell g. An alternative arrangement is shown in Fig. 2, in which light from two lamps b, c is transmitted after rejection from a surface d through apertures in a film guide, and through the film, to a photo-electric cell. The Specification as open to inspection under S'ect. 91 (3) (a) comprises also the following subject-matter which does not appear in the Specification. as accepted. Several sources of light may be used in conjunction with records bearing a number of separate sound-traces. Also, each lamp may be associated with a separate photoelectric cell. An example of the latter arrangement is shown in Fig. 3 (Cancelled), wherein three lamps k, l, m transmit light through three different points of the film simultaneously to separate cells q, r, s. The substitution of one lamp for another, where several are interchangeably mounted " in a common aggregate " may be effected either by hand or automatically. When the film passes over a guide roller, the roller may be made partly of glass. If window-like openings are provided in the film-guides, they may be slidably adjustable so that the distance between them may be varied, in order to adjust displacement of phase in the sound-reproduction.

Resulting 11#-ols may be oxidized to 11-ones and 17-acylates may be hydrolysed to 17α-ols and subsequently re-esterified. Acylation of the free 17α-OH-17#-CO 2 H compounds with carboxylic acid anhydrides results in the formation of 17α-esters of the mixed anhydrides which are then subjected to solvolysis to give the free 17#-CO 2 H compounds. Substituents in the alkyl group R 4  may be interconverted by standard procedures or formed from other substituents, e.g. a hydroxyalkyl ester may be prepared, then converted via a sulphonyloxy ester to a halo-alkyl ester or, alternatively, O- acylated. Products wherein R 4  contains an α-halogen atom may be obtained by reacting the 17#- CO 2 H compound with an aldehyde and a hydrohalic acid. #<SP>1,4</SP>-products may be partially reduced to #<SP>4</SP>-products. 17α - Hydroxy - 17# - carboxy - steroid starting materials are prepared by oxidation of pregnanes containing a 17#-COCH 2 OH side chain.

Title: Improvements relating to electronic switching units and to circuits incorporating such units
Inventor: LINDSEY CHARLES HODGSON
IPC: H03K19/16
Filed: 1959-01-28
Abstract: 886,942. Circuits employing bi-stable magnetic cores. FERRANTI Ltd. Jan. 25, 1960 [Jan. 28, 1959], No. 3004/59. Class 40 (9). An electronic switching unit comprises two cores 1, 5 each having set windings 2, 6 and reset windings 3, 7 and having series-connected output windings 4, 8, the windings 8 and 6 being connected in a positive feed-back circuit including a transistor 10. Bias from terminal 9 normally holds transistor 10 in the non-conducting state. Core 1 is first set and then when it is reset the output voltage from winding 4 starts the transistor conducting to permit constant current from a source 12 to pass to the output terminal 11 via the set winding 6, thereby causing the commencement of the setting of the core 5. This then proceeds by regenerative action due to the consequent output from winding 8 being applied to the base of transistor 10. By including a suitable resistor 19 in shunt with winding 8 the setting time of the core 5 can be made to exceed appreciably the duration of the reset pulse applied to winding 3, thereby providing a prolonged output to the terminal 11. The core 5 may be reset by a pulse applied to winding 7 or alternatively a permanent bias may be applied to this winding for this purpose. Fig. 2 illustrates a stepping register utilizing a plurality of these circuits, the setting windings 2 of all cores 1 except the first being included in the output circuits of the transistors of the previous stages. Pulses of a pulse train IP reset any set core 1. Thus if core 1 of the first stage is set over its winding 2 the first stage operates to the first pulse of the train IP to produce a prolonged output over lead OPC1 via the setting winding 2 of core 1 of the second stage. Thus, during the prolonged period, after the IP pulse ceases, core 1 of the second stage is set. The next IP pulse then operates in a similar manner on the second stage and so on. The setting winding of the cores 1 may be replaced by two windings both of which must be energized simultaneously in order to set the core. If such an arrangement is used for the cores 1 of Fig. 2 one of these windings only may be connected in the output circuit of the preceding stage and the stepping may be stopped at any stage of the chain by omitting to energize the second set winding of that stage.
