Abstract: 553,416. Variable pitch propellers. MILNER, H. L. Nov. 18, 1941, No. 14838. [Class 114] [Also in Group XXXIV] In high-speed bearings in which both the inner and outer races rotate in opposite directions a calibrated flow of lubricant is fed to the bearing and collected by centrifugal action in a sump, the level of the lubricant in the sump being kept at a constant level by a pump operated by the relative rotation of the races. The pump may deliver the lubricant to the supply and may consist of two radial flanges 33, 34 formed or mounted on the sleeves 19, 16 carrying the races 18, 17, flange 34 having a spiral groove 36. When applied to the pitch changing of contrarotating propellers, as described in Specification 538,621, the inner shaft 11 is hollow to deliver lubricant through passages 30, 32 to the bearing which has a seal 27 with inturned part 28.

Title: Improvements in methods of and apparatus for feeding bags one at a time for bag filling operations
IPC: B65B43/36
Filed: 1929-05-13
Abstract: 333,530. Brooke Bond India, Ltd., and Wood, C. May 13, 1929. Filling materials into paper and like bags.- Paper, linen, or parchmentized cloth bags are fed and opened in preparation for filling with tea &c. The bags 3, Fig. 1, are placed in a sector shaped holder 2, with closing flaps 3a to the rear, and are urged forward into engagement with clips or ledges 2<a>, 10, 11 by a presser foot 6 on a weighted bell-crank 5. A clip 13a retains the flap of the foremost bag while air jets, from nozzles 15<a>, 16, blow into the mouth of the bag to distend it as shown at 9<a>. The nozzle 15<a> is flattened to initiate the opening and the nozzle 16 assists in keeping the bag open. The bulging of the bag shown in Fig. 3 and the consequent lessening of the width causes it to be released firstly from the clip 11 so that it can be removed by the small end of a filling funnel (not shown) in the direction of the arrow 18. The air valve is geared with a revolving turret carrying the funnels, which are adapted to be tilted so as to enter the bags. The apparatus may be used in conjunction with those described in Specifications 333,528, and 333,529, [Class 106 (v), Measured quantities &c.].

Title: Iodonium salts and conversion products thereof
Inventor: REID JAMES ANGUS WILSON
IPC: C07C25/18
Filed: 1965-04-08
Abstract: Di-(p-tolyl) iodonium salts are prepared by (1) reacting p-iodotoluene with a peroxy compound to produce p-iodoso- or p-iodoxytoluene and (2) reacting the product, preferably without isolation, with toluene and an acid to form the di-(p-tolyl) iodonium salt of the acid. Peracetic acid is the preferred peroxy compound. The reaction is preferably effected at a temperature below 20 DEG  C. in a medium containing only a minimal proportion of water and preferably in a mixture of acetic anhydride and acetic acid.  The products are useful in preparing p-tolyl derivatives of nucleophiles, p-iodotoluene being simultaneously re-formed. Examples describe (1) the preparation of di-(p-tolyl) iodonium hydrogen sulphate and (2) the conversion of this product into p-cresol and p-iodotoluence by acid hydrolysis in the presence of a cuprous catalyst.

Filed: 1937-05-31
Abstract: 482,555. Pressure gauges. SASAKI, R. May 31, 1937, No. 15093. Convention date, Feb. 1. [Class 106 (ii)] Comprises a particular construction of gauge of the hydrostatic ring balance type in which a liquid seal is provided between the gauge and rigid pipes supplying the pressure fluid thus minimizing friction and in which the indicating mechanism gives a very magnified reading. The annular ring 1 is divided by a partition 3 into chambers 1<1>, 2<1> and contains a liquid 9 as usual. A gear 6 at the centre firmly supported by arms 5 connected to the tube 1 meshes with a gear 7 carrying a pointer 8 which moves over a scale board 4 secured to the inner side of the tube 1. The scale and pointer move in opposite directions giving a magnified reading. A cylindrical body 10 concentric with the tube 1 and rigidly connected thereto by pipes A<1>, B<1> which connect with pipes A, B dips into liquid contained in a stationary vessel 14 into which the pressure fluid supply pipe All, B<11> are led as shown. A partition 11 divides the body 10 into two chambers. The body is cut away as shown the angles #, #<2> being chosen such that in tilting the chamber 10 allows of the maximum reading of the gauge without fouling the pipes A<11>, B<11>, and without the edge 13 breaking the surface of the liquid. Instead of the gears cams may be used so that the How may be read directly. Also, if desired, the pointer may be formed as an electric contact arm moving over a resistance so that pressure or flow may be indicated or recorded at a distance. If desired, a fixed scale board may be used.

Title: Improvements in or relating to record changers

Filed: 1966-04-05
Abstract: 1,087,490. Record changer spindles. V-M CORPORATION. April 5, 1966 [April 20, 1965], No. 15127/66. Heading G5R. In a record changer having a spindle of the type where a number of retractable fingers 26 support the record stack, a record is smoothly released by lowering the fingers to the level of the turntable before the fingers are retracted, a secondary support 50 retaining the remaining records. The fingers are held by a carrier which is supported by a ball train 64, the other end of which is held in position by the end 96 of a pivoting arm 88. This arm has an opposed end 102 which is constrained to run in a channel in a cam-plate 106. When a change operation is to be initiated, the cam is rotated, rotating the arm 88 and withdrawing the end 96 so that the ball train falls down its channel, allowing the supporting fingers to fall. When these reach the ends of their channels 24, they retract and deposit the record on the turntable. The cam continues to rotate and pushes the ball train back up its channel to return the fingers to their support position. The use of a ball train enables a mechanism which is not extra long in a vertical direction to be used.

A press plate assembly comprises a press plate 22 having a front pressing face and a steam diffusing member 14 positioned on the other side of the press plate, the two being rigidly fastened together to form a unitary construction and to provide between them a steam chamber of fixed dimensions, and means for readily attaching the assembly to the press head of a garment press. The steam diffusing member 14 comprises arches 15 extending from the lower or upper or both sides of the member 14 and providing side openings 16, 17 for steam. The press plate 22 may be perforated as at 23, and small burrs 27 formed around each aperture during punching may be removed if a smooth upper surface is desired. The plate 22 may be of aluminium or stainless steel or a synthetic resin plastic, and may have a rough surface formed by particles of fine sand, grit, aluminium or other metal. Alternatively the plate 22 may have a smooth pressing surface. The pressplate 22 has a peripheral flange 30 and a metal angle strip 32 extending continuously along the length of flange 30. The angle strip 32 may be of one piece or a number of successive strips. The flange 30 and angle strip 32 are provided with beaded portions 31, 33, respectively. Clamping strips 36 are provided at spaced intervals around the periphery of the press plate assembly to retain the diffusing member 14 in position, these strips 36 being tightly gripped within the bead 31. Alternatively the angle strip 32 may be an extension of the member 14 or the strip 32 may be omitted. The assembly is held in position on the press head by means of springs (Fig. 1, not shown). A supplementary press plate (Fig. 5, not shown) may be provided for ready attachment to the assembly by means of clips or a suitably shaped edge portion. One of the two press plates will have a smooth surface and the other a rough surface. Burrs on one or both plates may be used to space them apart. One or both of the press plates may alternatively be imperforate. Reference has been directed by the Comptroller to Specification 759,865.
