Abstract: 381,548. Displaying. SUMMERSON, S., Llwyngwril, Merioneth. June 26, 1931, Nos. 18542/31 and 8467/32. [Class 3 (i).] To increase the facilities for shop window display in premises having limited window area, goods are displayed in a position remote from the window and an optical system is arranged between them and the window to present to an observer looking into the window an image of the display. In Fig. 1 the window space is divided into three parts 1, 2, 3, of which the parts 1, 2 are used for the direct display of goods, while the part 3 is used for the display of goods on an upper floor 4. The optical arrangement comprises a convex spherical mirror 5 on the floor 4 and a concave spherical mirror 6 in the window. The mirror 5 produces a virtual image 8b of an object 8, the distance of this image from the mirror 6 being less than half the radius of the latter so that the observer sees an enlarged virtual image 8a. If the image 8b is formed at a point outside the principal focus of the mirror 6, a system of lenses may be arranged between the mirrors to form a real image of the image 8b, within the said focus so that the mirror 6 produces a virtual image. One or more of the optical elements, or the display itself, may be movable to attract the eye or to increase the area of display.

Title: Improvements in or relating to the manufacture of artificial threads having fluctuations in count
IPC: D01D5/20
Filed: 1938-06-30
Abstract: 516,458. Spinning &c. machines. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEARCH. June 30, 1938, No. 19470. Convention date, July 28, 1937. [Class 120 ii)] [Also in Group IV] Artificial threads having fluctuations in count are obtained by passing them, between the spinning jet and draw-off member, around a pair of thread - deflecting members at the ends of a one-armed lever mounted on a shaft which is operated so that the lever alternately swings outward from its equilibrium position, so as to form a step in the thread passing round the thread deflecting members, and then swings back under its own weight. The lever is operated so that the intervals between successive formations of the step in the thread are continuously varied. As shown in Fig. 1, the thread 12 passes round the rollers 17, 18 mounted on lever 16 which oscillates about shaft 19. As shown in Fig. 2, grooved cam discs 20, 21 are mounted on shafts 22, 23 connected by a conedrive 24. 25. The discs move contact-makers 28, 29 along rails 26, 27. By means of relays, an electromagnet 34 is operated when contact is made. This attracts lever 35 and causes frictional coupling between gear wheel 38 and chain wheel 39 to be disengaged. Lever 16 on shaft 19 then drops by its own weight. When the circuit is broken the rocking lever 35 engages the coupling again under the influence of spring 36. Specifications 321,762, [Class 2 (ii)], and 370,017 are referred to.

Filed: 1939-07-05
Abstract: 530,908. Weighing apparatus. OTT, W. July 5, 1939, No. 19594. Convention date, July 27, 1938. [Class 143] [Also in Group I] Pre-determined quantities of immunizing powder or liquid are added to pre-determined quantities of seeds, automatically by means of a balance operated by the weight of the immunizing material. The material is fed from a hopper a through a slot e on to the pan of a balance f, counter-weighted at i, which rocks with a bearing block g about an axis h and on reaching the desired quantity tips down the balance, the material then being discharged into a conduit u where it mixes with the seeds v on their way to a mixing drum. Simultaneously with the tipping of the balance, the slot e is closed by a slide at the end of a double-armed beam q counter-weighted at r pivoted on an angled lever o which swings about an axis p and is moved to the closed position by a stop n on the bearing block g engaging the lever and rotating it counter-clockwise. The quantity of immunizing material can be varied according to the seeds by varying the turning movement of the beam f by means of a sliding stop k, a smaller quantity of the material being weighed out when the stop is in the position k2 than when it is in the position k1. This calibration can be read off a scale near the stop k. The beam f in its discharge position falls upon the cross-piece of a bail l which swings about the axis h and is limited in its downward movement by a stop m. The beam is re-set by an upward movement given to the bail l by a vertical rod s pivoted thereto, which rod is operated by the feed control of the seeds only after the pre-determined quantity of seeds has been weighed out. If powder is used in the hopper, a stirring grid b may be provided which is continuously oscillated through levers C1, C2, between the base of the hopper and a plate d which covers the slot e to minimize the static head of the material in the hopper. Specification 515,169 is referred to.
