Title: Improvements in or relating to flight holders for darts and darts fitted therewith
IPC: F42B6/00
Filed: 1945-03-26
Abstract: 593,710. Darts. LOWY, F. March 26, 1945, No. 7584. [Class 132 (iii)] A flight holder for a dart consists of a shaft having at least one axial slot extending from its rear end towards its forward end, the shaft being screwed into the rear end of a dart, and a sleeve mounted on the shaft in an axially slidable but non-rotatable manner, co-operating means being provided on the shaft and sleeve whereby when one end of the sleeve abuts against the rear of the dart and the sleeve is rotated,. the resulting axial displacement of the shaft with respect to the sleeve causes the prongs formed by the slot or slots to close and grip the flights firmly. As shown in Fig. 1, the shaft 1 has two slots 2 at right angles to each other. The forward end of the shaft is of reduced diameter and is screw-threaded to engage in a screwthreaded hole in the rear of the dart body 6. A tapered section 7 of the shaft engages a correspondingly tapered part of a sleeve 8 which is capable of axial movement with respect to the shaft but is prevented from independent rotation by means of a rivet 9 which passes through the sleeve and one of the slots 2. When the sleeve is rotated relatively to the dart body 6, the shaft 1 also rotates but since it is screwed into the dart body it moves axially so that there is axial movement between the tapered parts of shaft and sleeve. The slots for the flights are thus opened or closed. The shaft may be made of a high tensile strength aluminium alloy. In another construction the portion of the shaft of reduced diameter extends to within a short distance of the rear and the sleeve is made correspondingly longer. In this case it is necessary to provide the sleeve with slots so that the flights may be properly fitted into the slots in the shaft. As shown in Fig. 3, the rivet 16 is not passed through one of the slots of the shaft but through a hole 17 of larger diameter than the rivet pin in order to allow axial movement of the shaft with respect to the sleeve. The construction of the dart may be modified by providing a tapered portion on the shaft only or the shaft may have a ridge or shoulder co-operating with a slight taper on the sleeve. The shaft may consist of a short threaded stock with four or more wires each having a kink equivalent to the taper of the others constructions. The taper portion of the shaft may be replaced by a series of pips or projections.

Patent GB-728550-A (GB)
Title: Polyesters
IPC: C08G63/20
Filed: 1953-03-24
Abstract: High molecular weight polyesters are made by condensing substantially equivalent proportions of (a) a hydroxyl-terminated ethylene glycol polyester of an aromatic dicarboxylic acid having an average molecular weight corresponding to from 5-50 repeating units and (b) the acid chloride of a polycarboxylic acid. Condensation is preferably performed in a solvent, e.g. ortho-dichlorobenzene or trichlorobenzene and may be performed in presence of a hydrogen chloride acceptor, e.g. pyridine.  The hydroxyl-terminated polyester may be made by any conventional method, e.g. (1) direct reaction of the dicarboxylic acid with excess of glycol; (2) ester interchange between an alkyl or aryl ester of the acid and excess of glycol; or (3) reaction between the corresponding acid chloride and excess of the glycol in presence of a hydrogen chloride acceptor, e.g. pyridine; the glycol being removed at the end of each reaction until the desired molecular weight is obtained.  The ethylene glycol may be replaced in part by another glycol.  Specified for reagent (a) are the reaction products of ethylene glycol with iso- and/or tere-phthalic acid.  Specified for reagent (b) are the acid chlorides of ortho-, iso- and tere-phthalic; the naphthalene dicarboxylic; the phenylene dicarboxylic; diphenic; the naphthalene dipropionic; dihydroacrylic and its sulphur analogue; 2,5-dichloroterephthalic; trimesic; 1,4,5,8 - naphthalene tetracarboxylic; cyclohexanonetetrapropionic; dicyclohexanoneoctapropropionic; polyacrylic; diphenoxyethane-4,41-dicarboxylic; diphenylmethane - 4,41 - dicarboxylic; 1,4 - bis(phenoxymethyl)benzene-41,411 - dicarboxylic; diphenylthioether - 4,41-dicarboxylic; succinic; glutaric; adipic; pimelic; suberic; azelaic; sebacic; brasslylic; fumaric; glutaconic; diglycollic; thiodiglycollic; alpha- and beta - hydromuconic; 1,2,4 - hexanetricarboxylic; tricarballylic; aconitic and dimalonic acids.  In examples polyethylene terephthalate of molecular weight 5960 is refluxed for 4 1/2 -5 hours with terephthaloyl chloride or isophthaloyl chloride in orthodichlorobenzene with evolution of hydrogen chloride.  The solvent is then distilled off.

Title: Improved spindle for supporting tubular members
IPC: B65H49/06
Filed: 1963-02-28
Abstract: 993,674. Bobbin holders. MASCHINENFABRIK SCHWEITER A.G. Feb. 28, 1963 [March 1, 1962], No. 8156/63. Heading D1J.  A tube holder which is adapted to support tube members of varying internal diameter and which has particular application in textile machines, e.g. for supporting bobbins and the like during unwinding operations, comprises a spindle body 5 and a toggle lever arrangement 16, 8 associated therewith which in operation secures and positions the tube member (e.g. H or H<SP>1</SP>) so that whatever its diameter the axis thereof (e.g.A or A<SP>1</SP>) is directed to a common point P. In its "inline" or extended position the toggle levers 16 and 8 lie wholly within a slot in the spindle body. In the working position a tension spring 11 acting on a lever arm 9 which is pivotally mounted on a pin 6 and which forms an extension of the toggle lever 8 deflects the toggle levers so that the tube member is gripped and aligned by the ends 16a and 19a of the lever 16 as shown in Fig.4. The end portion 19a deflects the tube wall away from the spindle body proportionally to the diameter of the tube to align the axis with the point P. To release and replace a tube a system of levers (Fig. 3 not shown) raises the arm 9 into contact with a stop 14, which contact coincides with the point at which the toggle lever reaches the in-line position in the slot in the spindle body. The tube is thus no longer gripped by the toggle lever. Continued movement of the arm 9 causes the spindle body and toggle levers to pivot as a unit about the pin 2 to an inclined position (Fig. 2 not shown) in which removal and replacement of the tube member is facilitated.

Abstract: 1384381 Web decurling apparatus MASSON SCOTT THRISSELL ENG Ltd 23 March 1972 [27 March 1971] 8197/71 Heading B8R A web decurling apparatus comprises two curl corrector rods between which a web W of paper, cardboard or like material passes, means for moving the rods transversely to the plane of a straight line path of the web to vary the curl correcting effect of the rods, means incorporating beam transmitting and receiving apparatus adapted to be focused on said material for sensing the extent and sense of the residual curl in the material after it has passed the rods and for producing a signal indicative thereof and means for feeding back the signal to control the displacing means. Preferably corrector rods as described in Specification 1,379,571, are provided and are displaceable by a motor driven screw to correct curl. The sensing beam is either light or sonic pulses focused either on one or both faces of each sheet cut from the web W by a rotary drum cutter 12 and fed in overlapping formation between opposed, laterally spaced conveyer belts 131, 132, the belts being separated by rollers 133 at one position along their run to allow the sheets to exhibit their curl. Excessively curled sheets may be fed by a switch 18 to a reject shoot 19. The signals from the transmitting and receiving apparatus are fed via an amplifier, a threshold detector which detects the amount of curl and a differentiator, which detects the sense of curl from the signals, to a polarity switch which drives the screw motor to urge the corrector rods in the appropriate direction. In the case of sonic sensors, the Doppler effect may be used to assess the sense of curl.

Title: Improvements in stays or holders for pivoted windows
IPC: E05F11/00
Filed: 1927-03-28
Abstract: 292,279. Lewis, C. A. March 28, 1927. Stays.-Windows pivoted about the lower edge are held in the closed and open positions by a latch member 20 on the upper window edge engaging a slotted arm 3 fixed to the window frame, the latch having a finger 22 for engagement with a shoulder 36 at the inner end of the slot and for supporting the latch in the forward or closed Position. When the window is opened a projection 26 on the latch rides over a shoulder 5' on the underside of the arm 3 and the window is then held in the partly open position, as shown in dotted lines in Fig. 1. The metal arm 3 secured to a plate 1 is slotted as shown in Fig. 3, and carries a depending pivot ally -mounted transverse member 32 which serves to prevent the release of the latch from the arm 3 except when the window is in the closed position and the latch member is first operated in a particular manner. The parts are assembled when the window is moved into the closed position, the upper part of the latch riding on the underside of the arm 3 and its forward part 25 pushing the stirrup 32 towards the window frame; the weighted end 21 then raises the forward end of the latch through the opening 9 in the arm 3. A lateral member 22 on the latch prevents the release of the latch from the arm 3 unless the latch is first pulled downwardly when the window is in an open position. The window is then moved to the closed position with the member 22 on the arm 3 until the shoulder 36 of the slots 8, 9 allows the forward end of the latch to press against the stirrup and to push it aside in order that the latch projection 22 may be moved freely down through the slot 9 without engaging the stirrup 32. To prevent the latch being disengaged unintentionally by the operator, a spring 34 is provided, which requires the sash to be pushed against the spring into the fully-closed position before the release of the latch can be effected.

Title: An automatic stop mechanism for sound reproducing machines
IPC: G11B17/02
Filed: 1930-03-17
Abstract: 350,951. Stopping gramophones automatically. CROSBY, S., 13, Camac Road, Twickenham, Middlesex. March 17, 1930, No. 8585. [Class 40 (ii).] Relates to automatic means for stopping a gramophone upon the completion of a record by means of a member which is rocked by a cam driven with the record into the path of a second cam similarly driven but is removed from the latter cam by the traverse of the sound-box, and when this traverse ceases, the second cam operates the member and applies a brake or switches a driving motor off. According to the invention, the aforesaid member is rocked about a pivot by the first cam and is displaced at right-angles to the rocking movement by the other cam. As shown, the pivoted member 9 has a forked end embracing a disc 7 mounted on the turntable spindle and provided with two cams 8, 10. A lever arm 3 is driven frictionally by another lever arm 2 mounted on the same pivot and connected by a pin-and-slot joint to the tonearm 1. A lug 4 on the lever arm 2 bears on a slide 6, and when the tone-arm 1 is in the starting position, Fig. 1, pushes the slide 6 against a spring 5, so that the end 6a of the slide lies beyond the end of the left prong 9a of the fork of the member 9. During the playing of a record, the cam 8 periodically bears on the right prong of the member 9 and rocks that member to the left, but the member is at once returned to the right by the lever arm 3 driven bv the movement of the tone-arm in the clockwise direction. When this traverse ceases at the end of a record, the member 9 remains in the position given to it by the cam 8, and the cam 10 then rides over and depresses the left prong 9a. Meanwhile, the slide 6 has been gradually moved by its spring 5 and the end 6a of the slide which is thicker has become interposed between the left prong 9a and a member 11, so that when this left prong is depressed by the cam 10 it depresses the end of the slide 6 and the member 11, which opens a motor switch or applies a brake 12, Fig. 3, to a brake wheel 13.

Title: Improved process for producing opaque photographs in natural colours
IPC: G03C7/06
Filed: 1921-03-21
Abstract: 182,167. Obergassner, M. March 21, 1921. Colour photography, screens and screen processes for.-A colloidal three colour screen is used containing partly dyes which by treatment with acids or alkalies, or by neutralization, oxidation or reduction, are rendered colourless, and partly substances which are originally colourless and become coloured by the same treatment, the effect being to convert the screen colours into the respective complementary colours. The colloidal (for example gelatine) grain screen is formed on a transparent base, the opposite side being coated with negative emulsion. The negative is exposed through the screen and completed in apparatus which protects the screen surface from the liquids used. The screen is then sensitized with bichromate and after exposure through the negative the unexposed soluble portions of the screen and the negative film are dissolved in warm water and removed. The screen which now forms a transparent but wrongly coloured positive is then treated with a colour rectifying bath to decolourise the original screen colours and reacting with other ingredients of the colloidal screen to form the complementary colours. The screen positive is applied to a white background giving an opaque colour positive. Particulars are given of a screen in which the particles are formed of gelatine in an alkali condition, the colourless components in the grains being subsequently rendered coloured by an acid bath, the coloured components in the grain being decolourised. To intensify or bind the colours a salt such as barium chloride mav be added to one or more of the sets of coloured grains and subsequently precipitated. Also as another modification the screen particles may contain colourless salts of diazo or nitroso compounds which are adapted to be converted into the respective dyes by suitable treatment.
