Title: Improvements in grinding mills
IPC: B02C7/08
Filed: 1931-02-21
Abstract: 373,617. Disc mills ; conical mills. HAMBLIN, W. G., 16, Overndale Road, Fishponds, Bristol. Feb. 21, 1931, No. 5494. [Class 59.] In a mill having a plain flat or conical lower grinding member, the coacting upper grinding member is formed of a single continuous band which is waved, serrated, or recessed at one or both sides which provides a continuous width of grinding face entirely around the band so that the material to be ground can only pass to the delivery side by traversing under a thickness of flat or conical grinding surface of the upper grinding member. A rotary flat or conical ring 2, Fig. 1, contacts with a waved, stationary ring 3 provided with recesses 4, Fig. 2, communicating with the hopper 1. The outside of the grinding ring may be recessed at 5 so that the grinding surface of the stationary ring is of zig-zag formation and recesses 7 may be provided in the face of the grinding surface to assist in the grinding action. A stationary mixing arm 8 may be provided loosely engaging the driving shaft 9 and one of the recesses 4, and vanes 12 may be provided to assist the feed to the grinding band. The walls of the notches 5 form scrapers which eject the material to the usual edge scrapers. The grinding surfaces may have an orbital movement and either'of the grinding members may be movable or stationary or both may be rotated but at different speeds and more than one grinding ring may be used.

Title: Improvements in or relating to fire extinguishing apparatus
IPC: A62C99/00
Filed: 1932-02-24
Abstract: 382,840. Fire-extinguishing. FOAMITE FIREFOAM, Ltd., 55, Great Marlborough Street, London.-(Assignees of Smith, C. F. ; Elmira, New York, U.S.A.) Feb. 24, 1932, No. 5508. Convention date, Feb. 28, 1931. [Class 47 (ii).] The sealing element of each extinguisher of a battery of fire-extinguishers is arranged to be opened as the result of the extinguisher being allowed to drop within its mounting. The dropping may be initiated manually or automatically. Preferably, the energy of each extinguisher, when dropped, is arranged to initiate the dropping of the next one in the battery. As shown, extinguishers with valve heads 1 are mounted for vertical movement in a frame 7, and deliver their contents by flexible pipes 5 to a common discharge pipe 6. Each valve head comprises a sealing disc for the extinguisher and a plunger 4 for rupturing said disc, and has also pins 8 engaging slots in a pivoted strut 9 which normally holds the extinguisher in raised position. The strut is held from rotation, under the weight of the extinguisher, by engaging a step 13. A pivoted lever 14 is urged by a weight 15 to turn the strut 9 in a clockwise direction, but is restrained by a thermal link 16. Upon failure of the link 16, the strut 9 is turned past its dead centre by the lever 14, and the extinguisher then falls under its own weight, causing release of the medium, for example carbondioxide gas, from the extinguisher. The strut 9 is looked against inadvertent release by a bevelled pin 23, which is only released when the lever 14 is released. The pin-slots in the strut 9 allow the extinguisher to be weighed from time to time without dismounting it. The extinguishers of the battery are interconnected, with lost motion, by slotted links 18, so that each extinguisher, in dropping, moves the supporting strut 9 of the next extinguisher of the series. In a modification, Fig. 13, the extinguishers are mounted in an upright position. The pins 8 are engaged in slots in bent links 26 which are pivoted at their upper ends to a cam lever 27 pivoted on the discharge pipe 28. When the cam lever is moved past its dead centre by a link 32, the extinguisher drops. This causes the cam lever 27 to rotate, so that its cammed end 29 engages the plunger 4 and drives it in to rupture the sealing disc.

Title: Weft stop motion for a weaving loom
IPC: D03D51/34
Filed: 1962-02-14
Abstract: 993, 244. Weft stop motions. W. DELUIS, J-D. DELUIS, E-A: DELUIS, R. DELUIS, and E. DELUIS, [trading as C.A.DELUIS & SOHNE]. Feb. 14, 1962 [Feb. 20, 1961], No. 5608/62. Heading D1E. A weft stop motion comprises a suction device which the weft, when present, partially closes so that the increased vacuum therein operates a switch to enable the loom to continue operating. The suction device may be on the sley at the shed edge to contact wefts laid by shuttles or, for shuttleless looms, may be a tube which enters the shed to  contact the weft. In Fig. 4 reciprocation of the sley 23 moves a cylinder 24 having a piston connected to a spring loaded lever 28 and the suction device is connected to the cylinder inlet 25. If the suction device is partially blocked by weft the increased vacuum pivots the lever 28 to close contacts 33, 34 to let the loom operate, if no weft is present the contacts do not close and the loom stops. In Fig. 6 suction is applied to both sides of a diaphragm 52 from a source 60, the suction device is connected to one side of the diaphragm 52 by a tube 54 and an adjustable vent tube 56 is connected to the other side. When a weft is present the increased vacuum in tube 54 upsets the balance of the diaphragm to either open or close switches 65, 67. Specification 902,700 is referred to.

Abstract: 1,249,200. Racquets for tennis and similar games. J. R. LACOSTE. 3 Feb., 1969 [27 Feb., 1968], No. 5792/69. Heading A6D.  A racquet comprises a 'bowed metal tubular frame I whose ends are brought together to form a support for a handle 4, and a metal stay 5. These two darts are joined in the areas 6 so that the contact covers as large an area as possible. The frame 1 is formed of flanges 11 separated by grooves 12, said flanges extending equally on either side of the median plane of the racquet. The stay 5 is also tubular and has a heart-shaped crosssection, i.e. flanges 13 are separated on the upper edge by a groove 14 and on the lower edge by a projection 15. The ends of the stay are partially crushed, see Fig. 2, the rate of deformation decreasing uniformly so that the projection 15 can lie in the groove 12 for the greatest possible length. The stay and frame can be connected by welding, riveting or brazing, the last method seeming preferable. To reinforce the racquet a thickness may be added to the tube 1. Depending on the weight and balance required this thickness can be uniform or the areas 6 can have greater thickness than the rest of the frame. The thickness is diminished by hammering, electrolytic processing or the frame may be formed on different sized tubes. Further reinforcement is given by braces between the stay and the frame.
