Title: Improvements in open-shed jacquard machines
IPC: D03C3/06
Filed: 1964-04-01
Abstract: 1,019,053. Loom jacquards. V. WITTENDAL. April 1,1964 [April 5,1963], No. 13437/64. Heading D1E. A double lift open shed jacquard has main needles A having downturned ends D situated between two sets of presser bars P, T which reciprocate in unison. Each main needle has a pair of projections engageable with the outer sides of the legs of a two-legged hook C so that when the associated reading needle G drops into a hole in the pattern card, the end D of the main needle remains in the path of presser bars P, T and is moved to the right (on odd-numbered picks) or to the left (on even-numbered picks), thereby flexing the left or right leg of the hook into the path of the griffe M1 or M2 which is rising at that time. As shown at C3, when a hook is lifted by a griffe, continued pressure by the main needle when the hook has reached its top position causes the hook to swing about its point of suspension on the griffe so that an outwardly-facing nose at its lower end comes to rest on a fixed locking bar R to retain the hook in the open shed position. When the reading needle G subsequently encounters a blank on a pattern card and therefore lifts the end D of the main needle clear of the presser bars P, T, the next griffe to rise engages the hook at the top of its stroke and lifts it slightly to disengage ,it from the locking bar R, whereupon the hook resumes its vertical attitude and can pass down between the bars R. To enable the griffes to engage the hooks in these circumstances even though neither leg is being flexed by the main needle, fixed deflectors V are provided to squeeze the legs inwards at the top of their travel. The fixed locking bars R and the co-operating noses on the hooks may be omitted if a movable locking grid is provided to hold the hooks in the open shed position by engaging their top noses. Instead of the top noses being inwardly directed as shown, they may be outwardly directed, in which case the ends D of the main needles are turned upwards.

Abstract: 738,428. Window regulators. WILMOT-BREEDEN, Ltd. July 19, 1954 [May 15, 1953], No. 13630/53. Class 20 (3).  A power-operated vehicle window regulator comprises a pair of parallel motion links 5, 6 pivoted at 7, 8 adjacent their inner ends on to a base-plate 9 and at their free ends to a support 10 for the lower edge of a window, not shown, the pivot axis 7 of the link 5 being spaced inwardly from its end to accommodate a rotatably mounted pinion 12 which has toothed engagement with a fixed toothed segment 18 on the base-plate 9 and with a toothed segment 19 of smaller radius on a quadrant 13 pivoted on the axis 7, the two toothed segments 18, 19 having a common centre of curvature at the pivot axis 7. The quadrant 13 has a toothed periphery 14 for engagement by a worm 15 connected to the armature spindle 16 of a reversible electric motor 17, rotation of which causes the pinion 12 to roll on the fixed segment 18 and impart the required angular movement to the parallel links 5, 6. The window is counterbalanced by a spring 11 connected between the free end of the link 6 and the base-plate 9. In a modification, a single spring balanced arm is utilized, a worm-wheel, driven by a worm and motor similar to the arrangement shown in Fig. 1, being pivoted to the base-plate on the same axis as the inner end of the single arm and having secured to one of its sides a concentric pinion which meshes with a planetary pinion, rotatably mounted along the single arm, and in mesh, at a diametrically opposite position, with a fixed toothed segment on the base-plate, the centre of curvature of this segment being the axis of the worm-wheel.

Title: Improvements in or relating to fluid operated measuring or testing device
IPC: G01M3/32
Filed: 1954-05-11
Abstract: 758,873. Measuring leakage; pressure gauges. CLANG, Ltd., and EVENDEN, R. S. May 11, 1955 [May 11, 1954], No. 13694/54. Class 106 (2). [Also in Group XXIX] A fluid-operated measuring device comprises indicating means which includes an annular tubular ring 14, Fig. 2, in which a fluid, e.g. mercury, is adapted to travel to give an indication relatively to a clock dial 15 mounted concentrically with the ring. As applied to measuring leakage the article 24 to be tested is mounted in an airtight manner in the removable cover 21 of a sealed chamber 16. A pipe 23 leading from the chamber 16 can be put into communication with either end of the ring 14 by means of three-way cocks 19, 20. The other end of the ring 14 can be connected by the same cocks to a pipe 13 leading to a pressure gauge 5, Fig. 1, and thence to a reservoir to which air can be admitted under pressure from a pump 3. Straight through cocks 7, 8, 9 are also provided for connecting various parts of the instrument including a standard volumetric reference 10. In operation air is pumped into the reservoir 4 and chamber 16 to any desired pressure with the ring 14 not in circuit, air is then slowly admitted to the ring 14 from the reservoir side to centralize the mercury 25 either at end A or end B and the chamber 16 is then placed in communication with the ring so that as air leaks from the chamber through the object 24 being tested the mercury moves round the ring at a rate which can be measured by the clock-hand 29. Preferably the total volume of the ring is 1 cc. and the mercury occupies the space of one scale divisions, i.e. one sixtieth cc. A 70 degree overlap is preferably provided between the ends A, B of the ring 14. By connecting one pressure on the reservoir side and a second on the chamber side of the ring 14, the instrument may be used to measure the rate of change of the two pressures relatively to each other.

Title: An improved theft-alarm and protection device for shop or like windows
IPC: G08B13/04
Filed: 1945-06-01
Abstract: 595,704. Burglar and like alarms. MAY, H. A. June 1, 1945, No. 13751. [Class 118 (i)] In a shop-window or like theftalarm system, a lever normally rests against the inside of the glass but is arranged to bounce away when the window is struck, and thus close electric circuits to operate cameras and close the window space with shutters. A pivoted lever h is mounted by means of a suction pad b on the inside of the window a or frame and has a contact d near its upper end. Cooperating with this is a second contact mounted on an arm o pivoted on a fixed portion i and retained in a vertical position by a leaf spring e. A spring-loaded adjustable thumb-screw f serves to keep the lever h normally resting against the glass a and the contacts d are adjusted so as to be not quite touching. Any unusual shock to the window will cause the lever h to rebound and close the contacts d, thus energizing one or more solenoids to release two spring-urged shutters across the window space, and to operate a camera. The closing of the shutters completes a circuit for an audible alarm. The resilience of the spring e combined with the inertia of the lever h enables the contacts d to remain closed for a longer period than if the spring e were absent. The lever h is prevented from rebounding due to normal shocks, e.g. from traffic, by a weight nut j, which is vertically slidable.
