Title: Improvements in hot gas engines
IPC: F02G1/057
Filed: 1948-03-30
Abstract: 645,298. Hot gas engines. SHELL REFINING & MARKETING CO., Ltd., LUBBOCK, I., and TIPLER, W. March 30, 1948, No. 8973. [Class 7(i)] [Also in Group XIII] The outer face of the or each cylinder head is exposed to radiation from a burner and an annular space surrounds the cylinder wall and contains a number of ducts for the flow of working gas into and out of the cylinder alternating with a number of separate ducts for the egress of combustion products from the burner and a plurality of radial passages or channels are formed in or on the interior face of the cylinder head and connect the ducts for the flow of the working gas with the interior of the cylinder. Each cylinder 1 of the engine (one cylinder only being shown) is provided with a combustion chamber 2 above a cylinder head 3. The products of combustion from a burner 4 pass into spaces 9 between fins 8 arranged in an annular space around the cylinder and after leaving the spaces 9 flow through a combustion air preheater 11 to a duct 12 leading to atmosphere. As shown (Fig. 2) there are a number of sets of fins 8 in the annular space and each set is separated from the next by a radial pocket 10 having fins 10a projecting into it. The upper end of the cylinder has an inturned lip 24 and fins 25 on the underside of the cylinder head 3 extend to this lip. In between the fins 25 streamlined fins 22 also carried by the cylinder head are located. Thus working medium in the interior of the cylinder can flow through spaces 26 between the fins into the pockets 10 and thus to a regenerator 19. Below the regenerator is located a cooler comprising tubes 20 for the passage of the working medium, which are cooled by fluid e.g. water circulated by a pump (not shown) from a tank 21. Below the cooler is a space 29 connected by a pipe 30 with the space below the piston of the next cylinder of the engine. The pipe 30 of the last cylinder (not shown) is connected to the space at the underside of the piston 18. Combustion air for the burner 4 enters at 13 passes through the preheater 11 and then through an annular space 15 between a refractory lining 14 and the combustion chamber. The preheater comprises a corrugated metal sheet having corrugations running parallel to, the axis of the combustion chamber. The fins 22, 25 assist in cooling the cylinder head. In a modification a large number of fine radial bores or channels in the cylinder head are provided instead of passages defined by a series of fins and connect the interior of the cylinder, with the gas ducts so as to provide cooling of the cylinder head by the working gas. If desired the head may be provided both with a system of fins and with a series of fine bores or channels. An air bleed 16 is provided for cooling the burner and preventing carbon deposits. The burner is ignited by an igniter 5.

Title: Improvements in and relating to the generation of an intermittent electric current
IPC: G01S7/52
Filed: 1948-04-02
Abstract: 649,939. Echo - sounding apparatus. HUGHES & SON, Ltd., H., and SPROULE, D. O. April 2, 1948, No. 9383. [Class 118 (ii)] [Also in Group XL (c)] An intermittent current for use in echosounding apparatus is generated by means of a condenser-inductance parallel circuit arrangement, in which the condenser is alternately connected to a source of direct current and an output circuit, and means are provided to prevent discharge of the condenser through the inductance after the condenser voltage has reached a maximum value. In Fig. 1, camoperated switches 14 and 31 are arranged such that initially switches 12 and 13, 15 are closed and current flows through inductance 11 from the direct current source 16, 17. Switch 13, 15 then opens, shock-exciting tuned circuit 10, 11 and switch 12 is timed to open just after one quarter of the oscillation cycle when the voltage across condenser 10 is at a maximum. This voltage persists until switch 13, 18 closes, when condenser 10 discharges through the output circuit 19 to produce a damped sine wave which is used as the echo-sounding pulse. The arrangement avoids the need for accurate timing of the closure of switch 13, 18, and is useful when the echo-sounder apparatus is required to operate at two speeds. Switch 12 may alternately be operated by the field of inductance 11, such that this switch releases where the field drops to a minimum level. In Fig. 3, a rectifier 22 is provided to replace the action of switch 12, and switch 13, 18 is replaced by an arrangement comprising a gasdischarge tube 21 which is fired at the appropriate instant by an impulse from condenser 23 applied through switch 26, 27 to the control grids of tube 21. In this arrangement a single pulse is applied through output circuit 19 instead of the damped sine wave as in Fig. 1. Rectifier 22 may be provided in the Fig. 1 circuit to replace switch 12, and switch 13, 15 may be operated by a relay for remote control purposes. The switches 12 and 13 may be associated mechanically with the recording stylus of the echo-sounding apparatus. Specification 436,159 is referred to.

Title: Improvements in or relating to exposure-regulating devices for pnotographic exposuremeters or cameras
IPC: G03B7/12
Filed: 1955-03-31
Abstract: 781,016. Photo-electric exposure control. HERTERICH, W. March 31, 1955 [April 2, 1954], No. 9420/55. Class 40 (3). [Also in Group XX] A device for controlling the setting of an exposure meter or a camera comprises a cylinder having a helical row of teeth which rotates under the action of a spring until the appropriate tooth engages the pointer of a photo-electric exposure meter. As shown, Fig. 2, cylinder 1 is cocked by lever 4 so that on release a spring (not shown) rotates the cylinder until one of the helical steps 5 engages a pointer 7 of a moving coil meter 6 positioned in accordance with light intensity on a photo-electric cell. The pointer is pressed on to a stirrup 9 which rotates a pawl 14 into engagement with a toothed wheel 15 to lock the cylinder. A further stirrup operated by a spring is released by an extension of the cylinder to brake the pointer as soon as the scanning movement starts. Fig. 9 shows the application of the device to a photo-electric exposure meter. Knob 30 is pressed right in against the action of spring 29, thus setting cylinder 1 in its central position through gearing 22, 16. Pointer 7 takes a position representing light intensity and plunger 30 is then released so that spring 29 rotates cylinder 1 into engagement with the pointer and at the same time positions a drum 23 attached to gear-wheel 22 so that one of a set of scales parallel to its axis appears in a slot in the face of the meter. In the camera arrangement shown in Fig. 11 pressing of lever 35 which can be coupled to the film winding arrangement cocks the shutter through lever 28 and an exposure regulating device of the type already described is set to zero. The scanning drum is geared to a housing 22 in which is a spring 32 which effects the rotation of toothed rim 33 on the cocking ring 34. In operation release lever 38 is turned so that the locking tooth 39 becomes free but is prevented from further rotation by engaging tooth 47. When the manual pressure on lever 38 is released it clears stop 47 and cocking-ring 34 rotates and the exposure regulating device is operated by watch spring 23. During the rotation of the cocking ring the perforated diaphragm disc 40 is rotated through lever 37 and opens the diaphragm to the extent set by pointer 7. If the setting is not sufficient the second ring of the diaphragm moves and, through drive-member 43, sets the shutter ring of the camera to a longer time.

Abstract: 843,121. Making incandescent electric lamps. GENERAL ELECTRIC CO. Ltd. May 20,1958 [March 22, 1957], No. 9503/57. Class 39(2). In the manufacture of a foot tube assembly for electric lamps and similar devices, the foot tube is supported with its axis vertical, a positioning member is introduced thereinto from below and lead-in wires are fed downwards through holes in a guide member located above the foot tube into recesses in the positioning member. The positioning member is then withdrawn still bearing the lead-in wires so that these remain in the position in which they are to be sealed into the foot tube. An exhaust tube may also be fed through an additional hole in the guide member into a further recess in the positioning member. In a continuously rotating machine for carrying out the process, the foot tubes 12 are fed to jaws 10 spaced at intervals round the apparatus and each associated with a guide block 20 comprising two sections pivoted together which close above the top of the foot tube forming two feeding channels 23 of the lead-in wire and a central feeding channel for the exhaust tube and with a mandrel 14 carried by a support 15 sliding on a shaft 16 and moved upwards and downwards by a cam 17. Initially the top of the mandrel just projects above that of the foot tube. The mandrel 14 fits closely inside the foot tube 12 and has two diametrically opposite grooves on its surface to receive the lead-in wires and a central hole of slightly greater diameter than the exhaust tube with an adjusting rod 36 mounted therein. At successive positions during the rotation of the machine, a lead-in wire 34 which may embody the usual fuse, is fed through one of the holes 23 into one of the grooves in the mandrel 14, the exhaust tube is fed through the central hole in the block 20 into the central hole in the mandrel, the second lead-in wire is similarly fed into place, and the mandrel moves downwards within a tube 13 so that the relative positions of the parts in the foot tube are maintained. Heat is then applied to the lower part of the foot tube and a pinch formed sealing the lead-in wires and exhaust tube in the foot tube. Air is then blown through the exhaust tube to create a hole in the side of the pinch and the mandrel and tube 13 are further lowered to free the foot tube assembly and allow this to be removed from the apparatus. Specification 835,921 is referred to.
