Title: Improvements relating to rackets and other ball-striking implements
IPC: A63B49/08
Filed: 1928-09-08
Abstract: 323,770. Lethaby, H. Sept. S, 1928. Handles.-The end of the handle of a ballstriking implement for games has attached to it an endless ring of an elastic substance and a covering cap enclosing the ring and the end face of the handle and forming with the ring an enlargement on the handle. The end of the handle a, Fig. 2, has applied to it an endless ring b of an elastic substance such as indiarubber which is held in position in a recessed seating at the end of the handle. In order to balance the implement a central hole is formed at the end of the implement handle to receive a weight c fixed in the handle by a wood screw c<1>. An enclosing cap e is applied to the end of the handle, the cap being either of a substance such as rubber adapted to be first moulded and vulcanized and then applied to be retained in position under its own elasticity or of a substance such as a solution of cellulose or of a cellulose derivative such as viscose adapted to be applied in a plastic condition and to set hard. In the modification shown in Fig. 4, the ring b is provided with an inwardly protruding collar b<1> adapted to engage with a peripheral groove extending around the handle a. In the modification shown in Fig. 6 the ring is dispensed with the end of the handle being enlarged and the cap-e directly applied, the edge e<1> of the cap engaging with a peripheral groove near the end of the handle. In the modification shown in Fig. 8 the ring b is applied within an annular cavity in the handle and the cap e is applied over the ring b with its edges engaging in an annular recess in the periphery of the handle.

Abstract: 1,209,981. Drying motor vehicles. G. WEIGELE and J. SULZBERGER. 30 May, 1968 [31 May, 1967; 2 Dec., 1967], No. 26034/68. Heading F4G. Washed motor vehicles are at least partially dried by wiping them with sheets of absorbent material which are moved over the vehicles, the sheets of absorbent material being dried, e.g. by suction, after wiping. The vehicles may also be moved during drying. The vehicles may be subjected to air drying before or after the wiping treatment. In the embodiment of Fig. 1 the car is moved through oppositely moving absorbent sheets 8. The sheets 8 are split at the bottoms thereof. The car sides are dried by absorbent sheets 24 on spring-loaded resilient carriers pivoted about 26. The car is air-dried at 27. The sheets 8 are dried by being conveyed against suction nozzle 22. In Figs. 4-6 (not shown), the absorbent sheets (8f) may be gathered to form pleats so that they also dry the sides. To ensure that the sheets engage the lower regions of the car sides blowing or magnetic means may be provided. The sheets may be sprayed with magnetic material or may have small magnets attached thereto.

Title: Improved method of concentrating aqueous solutions of acetic or formic acid
IPC: C07C51/44
Filed: 1926-10-19
Abstract: 281,827. Haworth, W. N., and Nelson, Ltd., J. Oct. 19, 1926. Acetic and formic acids.-Aqueous acetic and formic acids are concentrated by adding an acetate or formate respectively, distilling off the water, and then distilling off the strong acid, at least part of the distillation being under reduced pressure. In an example, 30 per cent acetic acid is distilled with anhydrous sodium acetate at a vacuum of 15-25 mm., at as low a temperature as possible; when most of the water is removed, the temperature is raised to distil off the strong acid. In the first stage of the distillation heated air may be employed to remove some of the water, but the first stage should be concluded under reduced pressure; the second stage may be effected at atmospheric pressure, but reduced pressure is preferable. The acetic acid vapour may be led through a mass of hot solid sodium or potassium acetate. It is preferred to provide in the still means for breaking up lumps, for instance a rotary still with scrapers may be employed, or a fixed still with agitating or grinding devices. In another example, formic acid of 30 pent cent distilled with anhydrous sodium formate at 50-55‹ C. and 10-20 mm. to distil off the water, and the strong acid is distilled at 130-140‹ C. at the same pressure, the receiver being cooled to -10‹ C.

Title: Reed support structures for electronic musical instruments
IPC: G10D13/08
Filed: 1963-07-04
Abstract: 1,042,057. Electronic musical instruments. WURLITZER CO. July 4, 1963 [July 5, 1962], No. 26556/63. Heading G5J. A support structure for vibratile reeds comprising a bar having a plurality of reed mounting positions spaced along the length thereof is stiffened by means of a flange which extends along the length of the bar. The invention is described in connection with an electrophonic musical instrument in which the reeds, which act as electrostatic generators, are set in vibration by means of keyboard controlled hammers. This is shown in Fig. 1, in which depression of key 26 causes the hammer 60 to strike the reed 28 and simultaneously lifts the damper 96 to allow the reed to vibrate in slots 102 in a fixed electrode 100 thus producing a variation in capacitance at a frequency equal to the vibration frequency of the reed. This Figure also shows the cross-sectional form of the reed support structure for the (thirty-two) reeds of the bass register. Fig. 2 (not reproduced), shows the mounting of the bass reed support 120 and of the treble (also of thirtytwo reeds) reed support 118 in the instrument casing 22 by means of wooden blocks 122, 124 and a steel bracket 126, mechanically isolating couplings 127, 132 (elastomeric pads 136, 146) securing the supports to bracket 126 whilst rigid couplings are utilized for blocks 122, 124 to prolong the reed ringing time. The reed support 118 which is shown in Figs. 3, 5, 6 and 8 (not reproduced), comprises a plate 154 provided with a tapering slot 170 (Fig. 5) to accommodate the vibrational operation of the reeds 28 which are mounted at spaced positions 174 with their upper surfaces co-planar with the bottom surface of the pick-up member 100, the latter comprising a conductive sheet insulated from the support structure and provided with slots 102 as described in connection with Fig. 1. In accordance with the invention, a trapezoidal-shaped flange 158 is provided on the opposite side of plate 154 to that on which the reeds are mounted and in alignment with the spaced positions 174. The flange reacts mechanically to the reed vibrations and in order to give the support sufficient mass a solid back-up element 178 is also provided. Additionally, stiffening triangular-shaped webs 180 (Fig. 8) are also provided. The bass-reed support 120 is generally similar but differs in that the stiffening flange has the form shown at 160 (Figs. 4 and 12, not reproduced), and the webs 200 are rectangular in shape.

The shovel is tipped to discharge by a cable 18 secured to the bucket and passing over a pulley on an upright 21 on the boom before being secured to a lever 22 pivoted to the framework 2. The skids may be adjusted in height by a pivoted bar 25 having a series of holes for selectively bolting to the boom. The angle of the boom can be similarly adjusted by a bar 15 pivoted to the framework 2. A transverse tie with adjustable threaded rods clamps the members 2 and 4 together.

Compositions comprising (i) a vinyl chloride polymer and (ii) from 1 to 30% of randomly chlorinated polyethylene having a chlorine content of 30 to 45% and having a melt index of 0À001 to 1À0 before chlorination. By the term " random chlorination," it is meant that each polyethylene chain is in part not chlorinated at all (the crystalline region) and in part chlorinated haphazardly in the usual manner (the amorphous region). Suitable comonomers for (i) are vinyl acetate, vinylidene chloride, maleic and fumaric acid esters, acrylonitrile, vinyl alkyl ethers, ethylene and propylene. The polyethylene used to prepare the polymer (ii) preferably has a density between 0À916 and 0À935. Plasticizers e.g. dioctyl phthalate, dioctyladipate, tricresyl phosphate and polypropylene glycol sebacate, stabilizers e.g. dibutyl tin maleate, pigments e.g. TiO 2 , and other additives e.g. carbon black, waxes, clays, stearic acid and polymethylmethacrylate, may also be present in the composition. In comparative examples, non-randomly chlorinated polyethylene is used in similar compositions in place of the randomly chlorinated polyethylene, and also randomly chlorinated polyethylenes of differing melt index.
