Title: Improvements in or relating to telescope systems
IPC: G02B23/10
Filed: 1953-05-01
Abstract: 749,690. Telescope systems. COOK, G. H., and KAPELLA, Ltd. April 28, 1954 [May 1, 1953], No. 12140/53. Class 97 (1). A telescope system, particularly intended for an alignment telescope comprises an objective formed in two parts, the front part being afocal and having telescopic power greater than unity so that an incident collimated beam will emerge from the front part as a collimated beam of smaller diameter to fall on an adjustable optical deviating device arranged between the two parts of the objective so as to displace the image formed by the whole objective on a graticule and which is observed in an eyepiece. As shown, the afocal front part of the objective comprises a convergent doublet A fixed relative to a negative component A<SP>1</SP>, the light deviating means comprising a plane parallel plate C being located between the component A<SP>1</SP> and a fixed doublet B, and the objective. being completed by a doublet B<SP>1</SP> mounted in a tube axially movable for focusing by a rack B<SP>5</SP> engaged by a rotatable pinion (not shown), the tube being restrained from rotation by a pin and slot B<SP>4</SP>, B<SP>3</SP>. Numerical data are given for one such objective in which the component A<SP>1</SP> is a doublet and for one in which the component B<SP>1</SP> is omitted, the component B being axially movable for focusing. The objective forms an image in the plane of a graticule D which can be observed in an eyepiece D<SP>1</SP>, D<SP>2</SP>. The light deviating plate C is supported in an annular mount C<SP>2</SP> having spherical surfaces engaging within a cell C<SP>1</SP> and being supported by a fixed ball C<SP>4</SP> and balls C<SP>5</SP>, C<SP>6</SP> at right angles thereto and carried by links E, E<SP>1</SP> respectively. The links have projections respectivey engaging rotary cams E<SP>4</SP>, E<SP>5</SP> moved by knobs E<SP>2</SP>, E<SP>3</SP>, rotation of both of which causes rotation of the block C about the ball C<SP>4</SP> and rotation of one of which causes rotation of the block about an axis joining the other two balls. The block C may be replaced by two similar blocks rotatable independently or linked for simultaneous similar rotation. The front of the telescope may carry a target which can be observed in a distant mirror to test the alignment thereof with the telescope axis. Also the graticule D may be illuminated by light from a lamp N, Fig. 16, which may be plugged into the telescope, the light passing via a condenser N<SP>5</SP> to a semi-transparent reflector N<SP>3</SP> or a beam splitting prism which directs on to the graticule' and allows the light-which is reflected back by a distant mirror to pass to the eyepiece. The afocal part of the objective may comprise a single compound component or a suitably arranged separated triplet system.

Title: Improvements in the production of staple fibre yarns or like products from continuous filaments
IPC: D01F2/28
Filed: 1939-04-22
Abstract: 527,881. Forming staple fibre yarns &c. from continuous filaments. DICKIE, W. A., and TAYLOR, W. I. April 22, 1939, No. 12163. [Class 120 (iii)] A staple fibre yarn or like product is formed from a bundle of continuous filaments by subjecting the bundle to the action of steam or hot water to serve as a softening agent for the material of the filaments, drawing the bundle while under influence of the softening agent over and in contact with a cutting surface against which they are pressed and moving the cutting surface relatively to the bundle so that the filaments are individually severed at frequent intervals and a continuous staple fibre yam or like product formed ; the filaments may be crimped or stretched or strained while under the influence of the softening agent and before they are converted into the staple fibre yam and may be drawn over and in contact with the cutting surface in the presence of the softening agent. The filaments may be of cellulose acetate or other organic derative of cellulose and the moist steam may contain the vapours of a solvent or softening agent. As shown continuous filaments 2 are passed through a tube 6i n which moist steam is applied to the filaments and then around a rotatable guide 7 to the nip of a pair of rollers 8, e.g. those described in Specification 424,830, for converting the filament 2 into a continuous staple fibre yarn which is wound up on a bobbin 11 ; the tube 6 is supplied with the moist steam from a header 15 and the nipple 13 for the exit of the thread projects a short distance into the tube to form a trap for condensed moisture ; the steam may be supplied to a jacket surrounding the tube which has inlets leading into the jacket. In a modification the steam is supplied to a jacketed chamber having rollers between or around which the filaments pass and are stretched. As shown in Fig. 5, the steam is supplied through a pipe 38 against a baffle 39 in a long jacketed tube 36 into which the filaments are led in a loop around a roller 42 at the end of a vertical rod 41 slidable in a support 40 to push the filaments down into the tube 36 ; the filaments are led to and from the tube by guide rollers 43 and pass through notches in the inwardly extending rim 45 of the tube and a circular plate 47 with rod 41 rests on the rim 45 to close the tube ; in a further form the steam inlet is above the bottom of the tube so that a small quantity of water or other liquid is maintained at the bottom of the tube and the roller 42 and the loop of filaments dip below the level of the liquid in the tube. The filaments may be crimped in the apparatus described in Specification 508,968 supplied with steam and pass from the crimping chamber to the cutting rollers. In another arrangement the cutting rollers are disposed in a jacketed steam chamber. Specifications 424,880 and 440,653 also are referred to,

Title: Improvements in or relating to the production and treatment of artificial textile fibres
IPC: D01F4/00
Filed: 1943-07-29
Abstract: The resistance of artificial fibres, filaments, threads and the like, obtained from solutions of lactic casein, to attack by hot liquids, is improved by subjecting them first to a preliminary hardening treatment and then to a treatment with an aqueous solution containing formaldehyde, at least 30 per cent calcium chloride and 3 to 7 per cent of hydrochloric acid.  The preliminary hardening treatment may be effected in a solution containing formaldehyde and sodium sulphate.  The solution is preferably neutral, its pH value being adjusted substantially to 7 by the addition of an alkali, e.g. sodium hydroxide or sodium carbonate.  In the examples, a solution of milk casein is extruded into a coagulating bath containing sulphuric acid and sodium sulphate.  The resultant threads are passed through an aqueous bath containing sodium sulphate and aluminium sulphate or through aqueous baths of sodium chloride and aluminium sulphate with sodium chloride, and preliminarily hardened in a bath or baths of a solution of sodium sulphate containing formaldehyde, the pH value of which may be adjusted to 7 by addition of sodium hydroxide.  They are then washed, dried, immersed in a saturated solution of calcium chloride containing hydrochloric acid and formaldehyde, and finally washed and dried.  Specifications 483,810, 502,710, 511,160, 512,640, 513,910 and 533,952 are referred to.

Title: Improvements relating to electric relays
IPC: H01H51/30
Filed: 1949-05-11
Abstract: 658,130. Electromagnetic relays. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and KING, K. G. May 11, 1949, No. 12527. [Class 38(v)] A relay responsive to A.C. but not to D.C. has an armature 7 attracted to pole pieces 5, 6 which are connected by two parallel cores 1, 2 rectifiers being inductively or conductively associated with the operating winding or windings so as to divert the flux to the pole pieces and operate the armature. In the form shown in Fig. 1 there are two operating windings 9, 10 in series and D.C. current would merely produce a flux circulating in the closed magnetic circuit 1, 3, 2, 4. Short circuited windings 12, 13 provided with rectifiers 14, 15, however, prevent the growth of flux in the cores 1, 2 alternately at each half-cycle when A.C. is used so that a unidirectional flux passes through the poles 5, 6 and armature 7. In modifications the rectifiers are connected across the windings 9, 10 or the windings may be parallel with a rectifier in series with each. In Fig. 2, the cores 1, 2 are connected by a central member 16 which carries the operating winding 17. There are  four short-circuited windings with rectifiers in series with them arranged so that for one half-cycle of A.C. current the flux takes the dotted path owing to the blocking action of the short-circuited coils 18 and 23; and for the next half cycle the flux will pass upwards through the winding 18 and parts 5, 7, 6, 23.

'[Class 27] [Also in Group VI] An electrically-operated hair drier, comprises a hood 16, adapted to fit over the head and mounted on a wall cabinet 1 so as to be adjustable for height. the cabinet accommodating an electrically-driven blower 9 connected to the hood by a flexible conduit 11, coin-freed means for initiating operation of the blower and control means for switching it off after a time interval. As shown, the hood is carried by a pair of arms 21 pivoted to the top of the cabinet and its weight is counterbalanced by a spring 24 through the intermediary of a lever 25 and a link 28 pivoted to an arm 21. An inserted coin, in passing down the coin shoot 38, momentarily closes contacts 43, 44 to energize a relay 52 which then holds through contacts 66<SP>1</SP> and normally closed contacts 58 engaging a notched rotary timing disc 56 driven by a motor 55. Further contacts 64, 66 of the relay 52 also close to energize the .motor 55 and the blower 9. At the end of the period allowed, a notch 60 in the timing disc 56 opens the contacts 58 to restore the relay 52 and switch off the motor 55 and blower 9, the disc 56 over-running sufficiently to release contacts 58 ready for the next operation. An electric heater 45, connected in parallel with the blower 9 and controlled by a manually-adjustable resistance 47, is mounted in the air inlet 14 to the hood 16. The front of the cabinet is closed by a transparent mirror 4 which is illuminated from the rear by a lamp 5 when the apparatus is not operating, so that instructions or other information on the rear of the mirror then become visible.
