Title: Improvements in or relating to means for protecting detonators and fuses in blasting
IPC: F42B3/28
Filed: 1926-03-09
Abstract: 256,148. Griesel, J. D., and Griesel, F. J. S. March 9, 1926. Blasting detonators.- A blasting detonator B attached to a fuze C is inserted in a casing A of wax-like semi - plastic non - explosive material before introduction into a borehole. This protects the detonator from damp, injury, or accidental explosion. The open end or ends of the casing may be filled with similar material E more fully to protect the detonator. Suitable materials are mineral and animal waxes, fats, pitch, asphalt, hardened oils, fatty acids, and resinous substances.

Title: Improvements in and relating to electric-power steering gear for ships or other vessels
IPC: B63H25/26
Filed: 1919-03-19
Abstract: 138,744. Reid, T. March 19, 1919. Steering-gear.-A steering-gear comprises a continuously-running uni-directional electric motor which drives loosely-mounted wheels in opposite directions, a screwed rod on which is mounted the steering-wheel moving in a nut, and clutches, one of the two wheels driving a shaft actuating the rudder. The gearing also rotates the nut to provide a hunting-gear action on the screwed rod. The motor drives a shaft b, a bevel-wheel f on which actuates two bevels g, h loosely mounted on the control and lay shafts d, c but having clutches i, j whereby they are clutched to the lay-shaft d, which transmits the drive through reduction gearing to a worm-wheel s on the rudder-actuating shaft e. The shaft or rod c is moved longitudinally in a nut w on rotation of the hand-wheel, whereby the collar-portion l compresses the clutches i or j and the lay-shaft is driven. When the shaft e is rotated, gears t, u, v rotate the nut w oppositely to form a hunting-gear.

Spray carburettors.-The fuel nozzle comprises a body 5 to the head of which are secured by a cap 16 perforated plates a, b and a plate c with a double conical outlet orifice 14. The top of the body 5 has a recess 8 which is fed through a passage 6 and communicates through holes 10 with semicircular channels 7, 9 in plate a, and these channels communicate through tangentially arranged holes 12 with a space 15 immediately below the outlet orifice 14. The channels 7, 9 are separated by ribs o, Fig. 4, and the holes 10 enter near the ribs. The orifices 12 in the plate bare at the opposite ends of the channels from the holes 10. The jets of fuel impinge and become partly atomized in the space 15, the atomization being completed in passing through the orifice 14. The areas of the passage 6 and orifice 14 are the same and equal to half that of the holes 10 and 12. The nozzle prevents an excessive flow of fuel with increase of suction. The Specification as open to inspection under Sect. 91 (3) (a) describes a. nozzle, the details of which, shown in Figs. 4, 7<a> and 8 (Cancelled), are slightly different from those in the Specification as accepted, e.g. the plate a. is plane on its under side instead of being bulged and the orifices 10 are inclined; further, the top plate b is shown in Fig. 8 (Cancelled) turned aside to facilitate cleaning of the channels.

Abstract: 579,010. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. April 14, 1944, No. 6902. Convention date, May 6, 1943. [Class 40 (iv)] In a multi-potential marking system, the selector is controlled by a relay QR connected between the wipers of the register and the selector. The relay is preferably saturated by the current resulting from the minimum potential difference (other than zero) between the wipers and may be associated with a rectifier which ensures that current always flows through QR in the same direction. QR may control the selector indirectly by way of a relay QRA, Fig. 2, which is shunted out while QR is operated but operates momentarily when QR falls. In a modification, Figs. 4 and 5 (not shown), the register and selector wipers are connected respectively to the windings of a differential relay.

Abstract: 507,686. Coating machines. KAY, L. March 8, 1938, No. 7191. [Class 95] [Also in Group VIII] A machine for smearing the edge of a fabric &c. with an adhesive and folding over the edge comprises a support for the fabric, an adhesive spreader traversing the support, and means for folding over the edge and pressing the folded edge. As shown in Figs. 1 and 4. the fabric support consists of fixed and sliding parts 29, 30. The adhesive-applying apparatus 19, 20 is traversed over the work by a screw 7 driven through a reversing clutch 8, 9 by a motor 17. At the end of the traverse the device 19, 20 is raised by an adjustable cam 22 and a rod 24 is pushed endways by the carriage 18 and an adjustable stop 25. This moves the clutch 8, 9 and reverses the screw 7 ; it also depresses a rod 28 which allows a clutch 41 to rotate a shaft 34 for one revolution. This shaft carries a mutilated wheel 36 engaging a rack 37 connected with the sliding support 30 ; it also carries a cam 35 for moving pivoted bars 32 carrying a flat bar 33. At each rotation of the shaft 34 the parts 29, 30 of the support are separated and the fabric pushed therebetween by the bar 34, the bar 34 is lifted and the folded fabric pressed between the parts 29, 30, these parts are again separated and, when t he gears 36, 37 disengage, the part 30 is caused by the spring 39 to hammer the folded fabric against the fixed part 29 of the support. As shown in Figs. 7 and 9 the'two-part support 46, 47 is I followed out and the adhesive is supplied by a roller 67. The movable part 47 of the support is then moved by cams to bend the fabric edge over a bar 57 (corresponding to the bar 33) and finally hammers the folded edge of the fabric against the fixed part 46 of the support. Any kind of adhesive-applying apparatus may be used, e.g. that described in Specification 453,230.
