Title: Improvements relating to alloys containing nickel and to methods of producing them
IPC: C22C19/00
Filed: 1931-12-23
Abstract: Alloys containing 2-99 per cent of nickel and having a lattice structure of the face-centred cubic type are hardened by including 1-10 per cent of titanium in the alloys and holding them at one or more temperatures in excess of 600 DEG  C., but not exceeding 800 DEG C.  The basic alloys to which the titanium is added may include alloys of nickel with copper, iron, manganese, and chromium in various combinations, and may contain small quantities of elements such as aluminium, silicon, and carbon usually present in iron and steel.  The hardening process may be applied to so-called marginal austenitic steels.  Specifications 375,776 and 375,777 are referred to.

Abstract: 881,008. Steering by outboard motor installations. CURTISS-WRIGHT CORPORATION. Nov. 6, 1958 [Nov. 7, 1957], No. 35711/58. Class 114. [Also in Group XXIV] A non-reactive locking device for an outboard motor-propeller steering unit A, Fig. 1, rotatable about an axis L on a bracket S secured to the transom of a boat comprises helical spring coils 20, 22, Fig. 3, arranged between driving and driven members 6, 9 and a sleeve 11 adapted to be normally fixed in a housing F of the bracket S. The outer ends 28, 29 of the coils 20, 22 are located in rings 26, 27 respectively clamped to an extension 8 of driven member 9 by rings 12, 14. The inner ends 20<SP>1</SP>, 22<SP>1</SP> are engaged by a key 34 of driving member 6 which passes through with lost-motion a slot 36, 37 in extension 8. The . arrangement is such that the coils 20, 22 are pre-loaded to frictionally engage internal surfaces of the sleeve 11 and rings 12, 14 to prevent movement of the driven member 9, any force applied to member 9 tending to expand the coils 20, 22 into tighter engagement. On a turning force being apllied to the driving member 6 however, the key 34 first retracts one of the coils 20, 22 depending on the direction of operation, and then engages one side of the slot 36, 37 to drive the member 9 freely, the other coil 20, 22 over-running. The sleeve 11 is releasably held in the housing F of the bracket S so that the locking action can be freed if desired.

Title: Improvements in or relating to slide changers for optical projectors, viewers and the like
IPC: G03B23/04
Filed: 1958-11-07
Abstract: 888,388. Magazine slide changes. KODAK Ltd. (Kodak A.G., and Nissler, S.) Oct. 26, 1959 [Nov. 7, 1958], No. 35785/58. Class 97(1). A slide changer for optical slide projectors, viewers and the like comprises a housing for receiving a batch of slides of different thicknesses in any predetermined sequence, a slide advancing member which engages an edge of the foremost slide only to advance it through a slot in the housing and a pivotally mounted blocking member which is spring urged to an operative position in which it is spaced from one wall of the slot by a distance less than twice the thickness of a thin slide so that thin slides can be advanced past the blocking member, one at a time, and is movable about its pivot to an inoperative position upon being engaged by a thicker slide to allow the passage of such thicker slide through the slot. As shown the slide changer comprises a tray 2 containing slides 4 of different thicknesses which are spring pressed at 7 against a wall 8, between which and the tray is a slot 9. This slot is partially closed by a cam shaped member 10 which. is pivoted to the tray and engages a spring loaded plate 15 urging it into blocking position: The slides are ejected from the tray by a member 20 which engages the edge of the foremost slide only, and which pushes the slide past the member 10, movement of the second slide 4b due to frictional forces being stopped by the member 10. When, however, a thick slide such as 4c is pushed by the slide advancing member 20 the blocking member 10 is pivoted to allow ejection of this slide. Attached to the slide advancing member 20 is a cam 24 which urges the second and other slides in the direction opposite to the spring pressure and a fixed stop 25 is disposed above the slide 4 to prevent upward movement of the slides on return of member 20 to its rest position.

Title: Organic compounds
IPC: C08G73/00
Filed: 1959-10-27
Abstract: Trifluoronitrosoethylene is prepared and so as its dimer while that of difluoro-chloronitrosoethylene is claimed.  In any example trifluoroiodoethylene, nitric oxide and mercury is irradiated in a silica flask for 48-76 hours with a 250 watt ultra-violet lamp.  The excess of nitric oxide is removed by admission of oxygen to the flask and agitation of the mercury to remove final traces of dinitrogen tetroxide and the volatile products are slowly pumped through two traps in series cooled by liquid nitrogen.  Distillation gives nine per cent of trifluoronitrosoethylene.  Trinitrosofluoroethylene is sealed in a silica tube with chlorotrifluoromethane to give a maximum pressure at room temperature of 40 atmospheres. The tube is exposed first to infra-red radiation at then while still so exposed, at 80 DEG C. to ultraviolet-radiation for 30 minutes, frozen in liquid nitrogen, opened and distilled to give fifty-six per cent. <FORM:0963633/C1/1> Specification 963,634 is referred to.ALSO:Nitrogenous polymers have a repeating unit containing adjacent carbon and nitrogen atoms in the main chain, the repeating units being predominantly of the formula:- <FORM:0963633/C3/1> where X is chlorine or fluorine. The polymers may also contain repeating units having one or more of the formulae:- <FORM:0963633/C3/2> where X is chlorine or fluorine. Specified polymers are those of vinylic nitrose compounds of general formula CF2=CXNO where X is chlorine or fluorine e.g. homopolymers of trifluoronitrose-ethylene and 1-1-difluorochloronitrose-ethylene and copolymers of trifluoronitrose-ethylene with 1-1-difluorochloronitrose-ethylene or of either or both these with one or more fluoroalkenes.  Specified fluoroalkenes are tetrafluoroethylene, chlorotrifluoroethylene and 1-1-dichlorodifluoroethylene.  The above polymers may be prepared by polymerising the monomers under pressure and temperature preferably in the presence of an initiating agent e.g., ultra-violet light. Further, polymers having repeating units of formula: <FORM:0963633/C3/3> may be pyrolysed e.g. at about 400 DEG C. to produce a polymer having repeating units of formula: -N=CX- with or without repeating units of formula: <FORM:0963633/C3/4> Specification 963,634 is referred to.

Title: Type printing telegraph system
Inventor: DALEN CHRISTIAAN JOHANNES VAN
IPC: H04L1/18
Filed: 1958-11-14
Abstract: 882,207. Code telegraphy. NEDERLANDEN, DIRECTEUR - GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Nov. 14, 1958 [Nov. 21, 1957], No. 36693/58. Class 40(3). A telegraphy system comprises means for correcting by repetition signals received mutilated and is characterized by the provision of memory stores in which are stored the signals received correctly between the reception of the mutilated signal and the repeated signal and by the provision of switching means for supplying these signals, and the signals obtained by repetition, to the printer in the correct order. The signals are sent alternately via channels I and II. At the transmitter of station S-A a converter 5/7 receives signals from a tape transmitter Stz 1 and converts them to constant mark-space ratio signals. These pass to channel I or II according to the position of switch Si and are also stored in the associated memory ghn I or ghn II. At station S-B the signals pass to a converter 7/5 and are checked by a testing device ST2 to detect any mutilation of the signals. If the signals have arrived correctly they are converted to their original form and passed to memory 5I and 5II. Switches KV1 and KV2 move synchronously with switch Si at the transmitter. An unmutilated signal in memory 5I or 5II is compared by tester ST2 with the signal previously received on that channel and now stored in memory 5<SP>1</SP>I or 5<SP>1</SP>II. If the signals are different the signal in 5<SP>1</SP>I or 5<SP>1</SP>II is printed, according to the position of switch Su, and the signal in 5I or 5II passes via switch t1 or t2, temporarily closed, to the memory 5<SP>1</SP>I or 5<SP>1</SP>II. In the event that a 'signal is received mutilated at station S-B no signal is sent to memories 5I or 5II and switches st<SP>2</SP> 1  and st<SP>2</SP> 2  are opened. To the receiver at station S-A is sent the signal previously sent on the same channel as that on which the mutilated signal was received at station S-B. At the receiver S-A, tester ST1 finds the similarity of the signals in the memories 5I, 5<SP>1</SP>I or 5II, 5<SP>1</SP>II and opens switches st<SP>1</SP> 1  and st<SP>2</SP> 2 . The signal received mutilated is still stored in memory ghn I or ghn II and is retransmitted. Signals correctly received at S-B during the repetition cycle have been stored and by suitable programming of switch Su all the signals are sent to the printer in the correct order. Preferably the channels use different frequencies and the system may be applied to a four channel multiplex system. Electronic relays may be employed for switching, Fig. 10 (not shown) and the system, by suitable modification, is capable of detecting and correcting a number of consecutive mutilated received signals. Specifications 693,211 and 882,206 are referred to.
