Title: Improvements in spray guns
IPC: B05B7/12
Filed: 1958-09-10
Abstract: 842,959. Spray guns. ZIPPEL, R., and ZIPPELL, B., [trading as ZIPPELL & CO., KOMM-GES., R.]. Sept. 10, 1958, No. 28993/58. Class 69 (3). Paint from an inlet 7 is delivered at an outlet 10 along with a central hardening agent from an inlet 13 passing through a hollow needle 9, compressed air being delivered from a channel 4 to the nozzle body 3, the trigger 17 retracting both the outer hollow needle valve 3 and the central solid needle 12.

Title: Improvements in or relating to furnaces
IPC: F23J3/02
Filed: 1919-11-21
Abstract: 159,298. Phillips, R. W. L., and Blaikie, J. R. Nov. 21, 1919. Ashes, collecting and removing.-Ashes &c. are discharged from furnaces into a duct which is flushed periodically by suddenly-released bodies of water. As shown in Fig. 2, ashes &c. are discharged through closure devices 3, 8 to shoots such as 5 leading to a duct 6 arranged beneath a series of furnaces. The duct 6 communicates with a reservoir 11, Fig. 1, to which water may be supplied from a condensing-plant. A counterbalanced weir 13, Fig. 3, hinged at 14 and adapted to assume normally a vertical position is arranged between the duct 6 and reservoir 11. When sufficient water accumulates in the reservoir, the weir 13 is tilted and water is discharged into the duct 6, the ashes &c. being swept into the pit 9.

Title: High-frequency transformer
IPC: H01F27/02
Filed: 1931-10-19
Abstract: 396,022. High-frequency transformers. HAZELTINE CORPORATION, 15, Exchange Place, New Jersey, U.S.A.- (Assignees of Macdonald, W. A. ; Little Neck, New York, U.S.A.) Oct. 19, 1931, No. 29053. Convention date, Nov. 28, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (ii).] Comprises a high-frequency transformer for use in a valve circuit of the type described in Specification 312,354, [Class 40 (v), Wireless signalling &c.], and consists in an arrangement of the primary and secondary windings to obtain a given amount of inductive and capacitive coupling between them. The secondary is a distributed winding 21 having an axial length greater than its diameter and is mounted on an insulating tube 20, the lead from the high tension end being connected to a terminal 22. The primary is a coil 26 of greater number of turns than the secondary, wound in a slot in a disc 24 which is mounted in the tube 20 remote from the high tension end of the secondary. The transformer is mounted on a metal panel 39 and covered with a metal case 29 which serves as an electrostatic shield. The connections from the windings are taken to terminals 22, 23, 27, 28 arranged in such a manner as to give least capacitive coupling. In modifications the terminal 22 is omitted and one end of each winding connected to a single terminal, and the terminals are re-arranged to obtain different amounts of capacitive coupling. In a further modification, to increase the capacitive coupling, the primary is mounted at the high tension end of the secondary. To obtain a further adjustment of the capacitive coupling the depth of the slot in which the primary coil is wound is adjusted.

Title: A fastener driving gun
IPC: B25C1/14
Filed: 1968-06-19
Abstract: 1,236,815. Cartridge operated driving tool. BETTERMANN ELEKTRO OHG. 19 June, 1968 [20 June, 1967], No. 29206/68. Heading B4C. A cartridge-operated driving tool for firing bolts, nails or the like into workpieces comprises a barrel 6 slidably mounted in a housing 1 and having a chamber 5 for a cartridge 4, and a guide 15 slidably mounted in the barrel. Stops 16 mounted in apertures in the barrel are urged by a spring ring 18 into slots 20 in the guide to limit movement of the guide. Surfaces 21 (see Fig. 4) rising out of the slots 20 are provided so that when the stops are positioned outside the housing the guide will be released upon rotation and longitudinal sliding. A catch 26 normally extending via a slot 31 into the path of piston 14 has shoulders 32 which coact with surfaces 33 on the barrel so that when the barrel is forced into the housing, upon contacting a workpiece against bias of spring 10 the catch is pushed out of the piston's path. Rearward movement of the barrel forces breech block 9 to a position in which a striker pin release catch 11 is in the path of movement of a trigger 12. To permit reloading and ejection of the cartridge, slidable cover 38 is moved to open opening 3 and the guide and barrel are pulled outwardly of the housing during which movement the piston is arrested by the catch 26 and continued movement of the barrel causes a piston tongue (not shown) to eject the spent cartridge. The guide 15 includes a magnet 24 for holding a fastener, and a buffer ring 22 against which the piston is forced if propelled by an excessive charge. An expansion chamber 37 is provided.

Abstract: 733,600. Photo-electric control of street lighting. FISHER-PIERCE CO. Oct. 22, 1953 [Oct. 22, 1952], No. 29244/53. Class 40 (3). A photo-electric street-lighting control unit is adapted to be mounted on a street light and includes control mechanism which is adjustable about a vertical axis. As shown, the control unit is mounted on a street lamp 10 by means of an adapter 24 which screws into a threaded hole on the top of the lamp. Mounted on the adapter is a housing 32 which may be an aluminium cylinder and which carries a flange 34 with a central boss 36. This boss is bored to fit over the portion 30 of the adapter and may be adjusted to any desired position about the vertical axis and then clamped in position by means of a set screw 40 (Fig. 3). The upper part 46 of the central boss is slotted at opposite sides of a diameter as shown in Fig. 8. The slots 45, 46 are of different widths and receive lugs on a plate 48 which in turn carries an insulating plate 52. Plate 8 is held fast to flange 34 by a screw in each lug and plate 52 carries three sockets for receiving electrical connecting pins. The lower ends of these sockets are connected to leads 56. The photocell 60 and its associated apparatus such as transformers, relays, &c., are mounted in a unit provided with plugs 68 which engage in the sockets in plate 52. Insertion of the photo-cell with the correct orientation is assured by members 64 which engage in the same slots in boss 36 as the lugs on plate 48. The unit carries a handle bracket 70, guide springs 72 and a shield plate 74. This plate is apertured at one point to allow light to reach the cell. Mounted on top of the housing is a dome 76 (Fig. 3) having an enlarged portion at its lower end which surrounds the top of housing 32. The dome rests on supporting lugs at the side of housing 32 and is held in position by clips 86 of known type. The dome has a central transparent zone 88.

Abstract: 284,969. Junghans, O. Nov. 16, 1926. Projectile fuzes.-Relates to clockwork fuzes driven by centrifugal force and provided with one or more auxiliary clockwork devices for releasing safety devices, as described in Specification 285,553, the timing disc 29, Fig. 1, of the main clockwork being adapted to release a lever 31 on a spindle 35, which in its turn releases the trigger 40 of a spring striker 32. According to the invention. the spindle 35 is so mounted that it can only rotate, and a separate inertia, bolt 37 is provided to lock the spindle 35 by engagement with a pin 36 thereon. On discharge, the bolt 37 sets back and releases the spindle 35, and the lever 31 comes to bear against the periphery of the disc 29. At the appointed time, a slot in the disc releases the lever 31, the spindle 35 turns round, and a notch 38 therein releases the trigger 40, which in its turn swings round and allows the firing pin 32 to strike a percussion cap 34. The flash from this is transmitted to a detonator 44, and the explosion communicated therefrom to the main detonating charge 47 through intermediate charges 45. 46. The intermediate charge 45 is carried by a brass body 48, and is normally in the safe position shown out of line with the other charges. During flight, the driving sector 51, Fig. 2, of an auxiliary clockworh 53 swings rcund and releases a pin 50, which in turn releases the brass body 48. This then swings round by centri. fugal force and brings the charge 45 in line with the charges 44, 46.
