Title: Improvements relating to umbrellas
IPC: A45B25/18
Filed: 1957-04-08
Abstract: 804,965. Telescopic umbrellas; sewing machines. GROWY CO., Ltd. April 8, 1957 [April 25, 1956], No. 11396/57. Classes 112 and 134 In a method of attaching a cover to the frame of a collapsible umbrella in which the inwardly folded edge of the cover is stitched to the ends of the ribs by means of stitches which pass only through the inwardly folded edge, the cover is first turned with its inner side L on the outside, Fig. 6, and the unfolded edge of the cover is sewn by means of a machine to the ends of all the ribs except one (26), thus leaving a pocket 27. The sewing machine, Fig. 13, comprises a table 30 and an arm 31 containing the mechanism for working the needle 32. Each umbrella rib is placed in turn in a groove 34 in a blade 35 fixed to the table 30, and a holder 39 is lowered to press the cover against the rib tip. The arm 31, or alternatively the table 30, is then moved in succession to three positions in a plane perpendicular to that of the drawing to stitch the thread 40 through a hole 17 in the tip and through the cover on both sides of the tip. The cover is then turned over by inserting the hand into the pocket 27, grasping the cover in the middle at the hole 13 and pulling it in the direction of the arrow A. The pocket 27 comes to lie on the opposite side of the frame with the right side R of the material on the outside, Fig. 8. The frame is then collapsed and shortened and inverted into the cover by turning it in the direction of the arrow B, Fig. 8. The hole 13 in the cover is next placed around a pin 28, Fig. 10, on the umbrella crown and secured by screwing on a cap, and the cover is secured to the inner ends of the outer parts of the ribs in the usual manner. The cover is finally stitched to the rib 26 by hand. The method is applicable to frames in which the rib tips are integral with the ribs, and produces the same result as was previously achieved by stitching the cover to detachable rib tips which were then inverted and secured to the ribs. Depending on the number of ribs and the number of telescopic sections of each rib and the stick, it may be necessary to omit stitching the cover to two of the ribs in the earlier stages. In an umbrella having a small number of ribs comprising three telescopic sections the cover may be initially stitched to all of the ribs.

Title: Improvements in or relating to turnstiles, and counting mechanism therefor
Inventor: DELUCE RICHARD
IPC: G06M1/08
Filed: 1950-05-10
Abstract: 681,226. Counting-apparatus; turnstiles. ELLISON & CO., Ltd., W. T. April 16, 1951 [May 10, 1950], No. 11650/50. Classes 106 (i) and 106 (iii). A turnstile rotatable in both directions has separate counters for indicating the total number of persons who have passed through the turnstile in each direction. As shown, the counters 13, 13a are connected by links 11, 11a to associated levers 8, 8a pivoted at their outer ends on pins 9, 9a. Pivoted on each lever 8, 8a is a dog 6, 6a spring-biased into engagement with the lever and arranged such that there is a dog on each side of a tooth 5, the tooth 5 being on a turnstile shaft or a toothed wheel driven by the turnstile. The number of teeth 5 are equal to the number of arms on the turnstile. When a turnstile arm is rotated to move the toothed wheel 4 in a clockwise direction as viewed in the drawing, the tooth 5 between the two dogs engages the dog 6 and swings it about its pivot 7 against the action of a spring 19 to allow the tooth 5 to pass the dog 6'without moving the associated lever 8 which is pressed against a stop 17 by a spring 14. In the meantime, the next following tooth 5 on the wheel 4 engages the dog 6a. The dog 6a is thereby pressed against the lever 8a to rock it about the pivot 9a in a manner allowing the tooth 5 to pass the dog 6a. This movement of the lever 8a is transmitted by the link 11a to the associated counter 13a to actuate the counter. When the turnstile is rotated in the opposite direction, counter 13 only is then operated in a similar manner. The turnstile may be provided with conventional locking means so that the arms may be allowed to rotate only in one direction or the other.

Title: An improved micrometer
IPC: G01H9/00
Filed: 1928-04-20
Abstract: 313,263. Neale, J. April 20, 1928. Vibrations, registering. - A device for determining the frequency and amplitude of vibrations such as may occur in machinery, buildings, musical instruments &c. comprises a mirror, subjected to the vibrations, for projecting a beam of light on to light-sensitive cells forming the arms of a Wheatstone-bridge system so arranged that the resulting fluctuations affect earphones or other receiving apparatus. The earphones are connected to the usual galvanometer circuit of the Wheatstone-bridge through a transformer, to which may be applied alternating current from a calibrated oscillator to balance the vibratory current and serve as a means to measure its frequency. As shown in Fig. 1, the mechanism H under test has associated therewith a stylus J attached to one end of a Bowden wire the other end of which is attached, directly or through a diaphragm, to a mirror C adapted to reflect a beam of light from a source A and optical system B on to a group of four selenium cells D forming the arms of a Wheatstone-bridge having a source of energy F and indicating instrument G. The alternating current in the circuit G is reproduced in the earphones N by the interposition of a transformer M. A third winding of the transformer is in circuit with an oscillator O adapted to be adjusted so as to neutralize the note in the earphones and thus afford a measure of the frequency. The selenium cells are arranged symmetrically in pairs about a central line EE, Fig. 2, being mounted in frames P carried by nuts Q on a right- and left-handed screw spindle R. By means of the micrometer and vernier control S the cells can be adjusted to measure the amplitude.

Abstract: 270,711. Permutit Akt.-Ges. May 5, 1926, [Convention date]. Chromyl chloride.-The production of chromyl chloride by the action of an acid chloride, such as chlorosulphonic acid, phosphorus pentachloride or oxychloride, pyrosulphuric acid chloride, antimony, tin, titanium, or silicon chloride; on chromic acid, chromates, alkali bichromates, or mixtures of acid chromates with excess of chromic acid, is carried out in the presence of a diluting agent, for instance, concentrated sulphuric acid, phosphoric acid, carbon tetrachloride, trichlorethylene, or ethylene tetrachloride, which does not decompose chromyl chloride. When chlorosulphonic acid is used, dilute sulphuric acid, or concentrated sulphuric acid diluted during the course of the reaction with water, is preferably employed as diluting agent, so that the sulphur trioxide produced is converted to sulphuric acid. .Hydrochloric acid may be introduced into the mixture during the reaction to reconvert the sulphur trioxide or other anhydride formed into chlorosulphonic acid or other acid chloride for continuing the reaction. The process may be carried out by using a mixture of sulphur trioxide or fuming sulphuric acid and hydrochloric acid to form the chlorosulphonic acid in situ, in which case the hydrochloric acid may be formed in situ from a chloride. Mixtures of other acid .anhydrides with hydrochloric acid may also be employed.
