Title: Improvements in or relating to feed pumps
IPC: F16N13/00
Filed: 1925-09-16
Abstract: 241,533. Lamblin, A. Oct. 18, 1924, [Convention date]. Diaphragm pumps; auxiliary actuating-gear.-A fuel pump for an internalcombustion engine comprises two diaphragm pumps 2, 3 symmetrically disposed about a shaft 28 carrying an eccentric cam 27 which engages a stirrup 26 connected between the sleeves 24 which carry the diaphragm 5. Instead of bearing directly on the sleeves as shown, the cam may bear on spring mounted bushes mounted in the sleeves, which bushes yield in the event of excersive pressure in the pump. Petrol enters the pump by way of passages 6. through filters 10 of leather or gauze arranged close to the inlet valves 12, and is expelled past valves 13 to a discharge pipe 19 communicating with the carburettor supply pipe and provided with a relief valve 21. Valves 62', 62<2> control passages leading to a hand operated pump for starting, or the device shown in Fig. 7 may be used, comprising a plunger pump 45 operated by a cable 55 and spring 56, and communicating by passages 49<1>, 49<2> with both pump chambers 2, 3. The diaphragms are made of vulcanized fibre, such as cotton fibre impregnated with zinc chloride, so as to be impervious to the petrol as well as to the oil in the chamber 4, and each diaphragm may be duplicated. The Specification as open to inspection under Sect. 91 (3) (a) also describes a construction of single diaphragm pump driven by an electromotor mounted on the same casing. The water drives a worm 73 which drives a pinion 74 connected by a one-way ratchet clutch with a shaft 75 carrying an eccentric 76 which actuates the piston 79 to which the diaphragm is fastened. A handle 98 may be fixed to the shaft for separate actuation. Two eccentrics driven in this manner may drive twin pumps. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to industrial pallets
IPC: B65D19/00
Filed: 1949-09-07
Abstract: 671,842. Pallets for handling loads. WILLIAMS, W. P. (Kappen, J. W.). Sept. 7, 1949. No. 23225/49. Class 78 (iv). [Also in Group XIV] A carrier for merchandise comprises a resilient metal corrugated sheet provided with two pairs of support-engaging members, one pair adjacent opposite ends of the sheet and the other pair intermediate the ends. The arrangement is such that the carrier flexes when supported by the first pair of members, but does not flex substantially when supported by the second pair. The combined tray and pallet shown comprises a rectangular sheet 11 of aluminium alloy or the like formed with corrugations of castellate form, the marginal corrugations being strengthened by wood fillers and the ends of the corrugations being closed by strip 14 welded to the sheet. A pair of hollow members 17 strengthened by wood fillers 19 serve as legs and as reinforcing mernbers while rails 25 at each end of the sheet are adapted to be supported by rollers set on the walls of for example a vehicle body. The sheet is sufficiently flexible to bend when supported by the rails 25 so that when it is mounted in a vehicle vibration will tend to compact the load into the middle of the tray. Plates carrying castors may be mounted on the underside of the sheet by means of members 21 and 22 and a latch 23.

In a system for automatically recording defects in sheet material 6 the scanning motion of an ultrasonic probe 2 over the material surface has two orthogonal components, the first being a discontinuous step-wise movement and the second being a reciprocating movement, defect signals from the probe actuate a writing instrument 5 movable relative to a paper-carrying recording drum 4 in a direction parallel to the drum axis, the writing instrument movement is electrically synchronized with the stepwise probe scan component and the drum rotation is mechanically synchronized with the reciprocating probe scan component. A conformal map of the defects is thus obtained. Details of the probe support and scanning arrangements are given. The defect signals are also applied to a B-scan oscilloscope 10 which displays a cross-section of material 6 along each probe scan line and the display is photographed by a camera in which frame-advance and exposure are synchronized with probe 2 reaching the end of a scan line and writing instrument 5 being advanced a step along the surface of drum 4. A photographic record of defect depth and position is thus provided.

Ink - ribbon mechanism.-A device for moistening the ink ribbon of a typewriter or the like comprises a casing containing a moistening-roller and a disengageable distributing-roller, and provided with a pivoted clip arranged to abut on the casing and hold the ribbon in light contact with the distributing- roller. In the device shown in Figs. 1 and 2, a knurled moistening- roller 23, projecting through a slot in the casing 10, runs in contact with a distributing- roller 17 mounted in a bracket 14 which is secured to a pivot rod 13 and is pressed towards the rolfer 23 by a spring. To disengage the roller 17, the bracket is moved by means of a finger-piece 20, frictional engagement of the finger-piece with a slot in the casing maintaining the roller in disengaged position. A spring-pressed clip 27 for guiding the ribbon is pivoted at 26 to the casing and has lugs 29 which engage the casing at points above path of the ink ribbon. The lugs prevent the clip from gripping the ribbon and also serve as guides. The roller 23 consists of felt and is supported by a hollow perforated core arranged under a filling-hole 11<a>. To prevent moistening of the red strip of a ribbon, the roller 23 may be stepped. The casing is provided with a detachable clip 32 for engaging the spool-housing or other member.

Abstract: 221,647. Berry & Co., Ltd., H., and Bull, G. Sept. 26, 1923. Testing strength of pipes.-Relates to machines for hydraulically testing pipes wherein the pipe is placed between headstocks and the points made by screwing up a follower prior to the test, and consists in the provision of auxiliary screwoperated followers, carried by auxiliary headstocks, pivotally mounted in slidable blocks adapted to be traversed in stationary longitudinal guide frames to render the machine capable of testing branched pipes, tees and bends. In Fig. 1 the machine is applied to testing a straight pipe with oppositely situated branches set angularly thereto. The headstocks 1, 2 carry the usual receiving ram 3 and main screw-operated follower 4. The headstocks are provided with side frames constituting guides 5, in each of which is mounted a slidable block 6 traversed by screw and nut mechanism 7. Pivoted in each block 6 is an auxiliary headstock 8 carrying a screw-operated follower 9. The ends of the main pipe are first sealed by the ram 3 and the follower 4 after which the blocks 6 are moved and their headstocks 8 swivelled so as to bring the followers 9 into alignment with the branch pipes, whereupon they are sealed by screwing them up against the pipes. The filling water is supplied and the proof pressure applied by way of a passage 13 in the head of the ram 3. In testing a tee-piece, a suitably shaped packing .is placed between one of the auxiliary followers and the main pipe, while in testing a bend a suitably-shaped packing is placed between the pipe and the main and one of the auxiliary followers.
