Title: Process of and apparatus for printing patterns on plush fabrics or the like
IPC: B41F15/08
Filed: 1928-06-14
Abstract: 308,123. Fairweather, W. C., (Pl³schweberei Grefrath Akt.-Ges.). June 14, 1928. Stencilling.-Patterns are printed on plush fabric or like webs by applying a stencil made of permeable fabric blocked out by impermeable material, spreading colour over the stencil by means of a pusher, and pressing the stencil against the web, and then stripping the stencil from the web in a direction perpendicular to the plane of the web so that the colour is sucked through the stencil on to the web. The web may be temporarily secured by an adhesive to an impermeable support with the object of preventing air getting beneath the stencil and destroying the suction. In the apparatus shown in Figs. 1 and 2, a stencil 4 is stretched in a frame 5 mounted on vertical guide pins 6 and adapted to be raised periodically by rotary cams 7 to strip the stencil from a web 35 fed intermittently by a spiked roller 3. Colour is spread over the fabric by a resilient pusher 11 carried by bars 12 mounted in a carriage 17, which is reciprocated one or more times for each advance of the fabric by means of a chain 33 led over a sprocket 32 on a shaft 31 geared to a shaft 28 carrying a sprocket 27 over which is a chain 26 having its end fixed respectively to levers 23 rocked about a pivot 22 by rotary cams 24. The pusher 11 is raised at the end of each stroke by pivoted cams 15 on to which rollers carried by the bars 12 ride and which tip up so that the pusher falls back on to the stencil behind the mass of colour. In Fig. 3, a web 48 is pressed by rollers 55, 56 on to an endless rubber band 54 previously supplied with adhesive from a tank 52, and colour is spread over stencils 44 guided on pins 46 by pushers 57, the web being subsequently stripped from the band 54 by a stripper 59. Fig. 5 shows a pusher carriage reciprocated on rails as in Fig. 1 and comprising a pair of pushers 71a, 71<b> mounted in vertical guides and curved at their lower ends. A lever carrying three arms 72a - - 72<c> is mounted on each end of a shaft 68, the arm 72<c> being engaged by a chain 73 to reciprocate the carriage and rock the shaft 68 so that alternately the arms 72<a>, 72b engage rollers 74a, 74<b> respectively to raise one blade and lower the other at the end of each stroke.

Title: Improvements in or relating to electrically operated fire detection apparatus
Inventor: STONOR CHARLES RICHARD PAUL
IPC: G08B17/06
Filed: 1956-06-04
Abstract: 822,470. Automatic electric fire alarms. SOUND DIFFUSION (AUTO THERMATIC) Ltd. May 10, 1957 [June 4, 1956], No. 17228/56. Class 118 (1). An electrically-operated fire alarm comprises detectors such as D connected together and to a relay operating an alarm circuit A by coaxial cables C, the insulation of the cable becoming fluid and the inner conductor sagging into contact with the outer conductor if the cable itself is heated. In the Figure, which shows the relay S in a de-energized condition, the coaxial cable C is connected at one end to supply terminals through a current limiting resistor R and at the other end is connected via a detector D to the relays S. If the detector D is overheated then a bi-metallic element E shorts out and de-energizes the relay S, and at the same time connects across the supply. Continued movement of E opens the contact d to remove the overload on the supply but keeps S shorted. The system may be re-set by a push-button P, and may be modified to cause current to flow only at alarm conditions.

Title: Motion picture projectors
IPC: G03B21/32
Filed: 1960-05-17
Abstract: 892,275. Kinematograph projectors. BELL & HOWELL CO. May 17, 1960 [May 21, 1959], No. 17355/60. Class 97(1). A kinematograph projector includes, besides the feed sprockets associated in known manner with the film gate, a sprocket for feeding the leading end of a film into a guiding channel from which the film emerges between the flanges of the take-up spool along a line intersecting the spool hub, the film, on its passage through the guide having been twisted slightly about its longitudinal axis by a plate set obliquely to the axis of the said sprocket so that, owing to its natural tendency to curl in the sense of rotation of the sprocket, the unperforated film edge tends to enter openings in the adjacent flange wall, rotation of the spool causing the edges of the flange openings to whip the leading end of the film against its curl until this leading end has been sufficiently advanced to come into contact with the spool hub which latter carries teeth for engaging the film perforations and latching the film to the hub. Figs. 2 and 3 show the film 22 emerging into the space between the flanges 30 of a spool from a guide element 28 adjacent the sprocket 27 and pivotally mounted on an axis 42 upon which is also rotatable a pressure roller for the film. Fig. 4 shows the crosssection of the guide 28, the oblique plate 48 imparting to the film 22 a twist about the longitudinal axis of the guide which axis initially intersects the spool hub 32 as shown in Fig. 2. The clockwise curl of the twisted film causes the unperforated edge 22a to enter the flange openings whereby the clockwise rotation of the spool will cause the spokes of the spool to whip the leading end of the film, as indicated in Fig. 2, until the latter reaches the hub. On the hub there is frictionally mounted a band 33 (Fig. 7) carrying punchedout tooth-like projections 33a, 33b which catch the perforations of the film and secure the latter to the hub, the inertial shock on the film being broken by the initial slip between the band and the hub. Friction on band 33 is provided by the shoulders of recesses formed on the hub and by resilient portions 29a of the flanges. The teeth 33a and 33b are slightly angled in opposite direction and alternately arranged so that a spool may be used for rotation in either direction. The tooth spacing on band 33 is such that when one tooth has entered a perforation the other teeth will not. The film can thus disengage easily on running off. The teeth are sufficiently short not to effect pile up of film on the spool hub. As the film piles up, guide 28 will pivot against spring- loading into the dotted position shown in Fig. 2 the amount of pivoting being limited by pin 45 and slot 46. A guide similar to 28 is associated with the second spool of the projector. The Specification describes projectors having various spool arrangements and modified forms of the film twisting guide.

Title: Improvements in or relating to hydrogenation catalysts and the application thereof
IPC: C07C403/00
Filed: 1950-07-13
Abstract: The selective hydrogenation of acetylenic unsaturation to ethylenic unsaturation in a compound which also contains ethylenic unsaturation is effected in the presence of a metallic palladium catalyst which has been modified by lead or bismuth (see Group III).  The hydrogenation is effected at normal temperature and pressure with the compound dissolved in an inert organic liquid, e.g. petroleum ether or methanol, and after separation of the catalyst, the product is crystallized out.  When the compound contains several double bonds in addition to the triple bond or bonds, quinoline is added to the reaction mixture.  Examples describe the hydrogenation of 1.6 - dihydroxy - 3.7 - dimethyl - 9 - [21.61.61-trimethyl - cyclohexene - 11 - yl] - nonadiene - 2.7 - yne - 4; 1 - methoxy - 3.7 - dimethyl - 6 - hydroxy - 9 - [21.61.61 - trimethyl - cyclohexene - 11 - yl] - nonadiene - 2.7 - yne - 4; and 1 - methoxy - 3.7 - dimethyl - 7 - hydroxy - 9 - [21.61.61 - trimethyl - cyclohexene - 11 - yl] - nonadiene - 2.8-yne-4 to the corresponding completely ethylenic compounds.ALSO:A modified palladium catalyst particularly for use in the selective hydrogenation of acetylenic unsaturation in the presence of ethylenic unsaturation (see Group IV(b)) is prepared by contacting metallic palladium in an aqueous medium with a lead or bismuth salt or a mixture thereof, e.g. lead acetate or bismuth nitrate, heating the mixture and then separating the modified palladium.  The metallic palladium may be suported on barium carbonate, barium sulphate, clay, calcium sulphate, calcium carbonate, magnesium oxide or charcoal.

Title: Improvements in and relating to the control of traffic signals
IPC: G08G1/08
Filed: 1958-06-03
Abstract: 853,007. Road signals for controlling traffic. FOREST CITY ELECTRIC CO. Ltd., and QUILLIAM, B. June 1, 1959 [June 3, 1958], No. 17617/58. Class 118 (2). A traffic signal has a constantly rotating electric motor actuating a cam-shaft whose cams operate four switches which control the traffic lights and also the speed of the motor and cam-shaft, the speed regulating the period of time during which a respective traffic light is illuminated. In a portable traffic signal, a motor M drives a cam-shaft which operates four micro-switches X, Y, C, D, the cams being so cut that the switches remain in their operated condition for one quarter of a revolution of the cam-shaft. With the switches as shown (all unoperated) the signals at both ends of a road show red R A , R B , and the speed of rotation of the motor is controlled by resistor R 1 . During the next quadrant of rotation (interval 1) switches X, C are operated, giving a green signal at one end G A , and controlling the motor speed by resistor R 2 . For the third quadrant all switches are again unoperated, and for the fourth switches X, Y, D are operated giving a green signal G B  at the other end, and connecting resistor R 4  in the motor circuit. Vehicleoperated switches P A , P B  at either end of the road are also included in the circuit to operate relays E, F. If light G A  is illuminated, traffic passing over pad P A  will cause relay E to operate to change-over contacts e, substituting resistor R 3  for resistor R 2 , to decrease the speed of the motor, allowing a longer period of " green " during periods of high traffic density in one direction. Relay F and resistor R 5   similarly extend the period of " green " for traffic moving in the opposite direction. The pads may comprise flexible tubes closed at one end, and having diaphragms at the other end which operate switch contacts.
