Title: Warming-up apparatus for internal combustion engine
IPC: F02B75/10
Filed: 1973-01-22
Abstract: 1406538 Regulating I C engines NISSAN MOTOR CO Ltd 22 Jan 1973 [25 Jan 1972(2)] 3159/73 Heading F1B An I.C. engine warming-up system comprises an engine temperature actuated switch 30, Fig. 1, closed at low temperature, an idling switch 44 closed when an acceleration control member 132, Fig. 2 is released, first electrical means 32 responding to the switch 30 when closed to cause deactivation of the cooling system 18, second electrical means 48 responding to both switches 30, 44 when concurrently closed to retard engine ignition and a fast idling device 110, Fig. 2 arranged to increase mixture supply at low temperatures when member 132 is released. At low temperatures when an ignition switch 28 is closed and member 132 is released to close switch 44 the solenoid of relay 32 is energized to engage a magnetic clutch 24 to stop the operation of a water pump 20 and radiator fan 22. Simultaneously a timer relay 48 is closed by solenoid 60 and a retarding contact breaker 52 retards the ignition for faster warm-up. Solenoid 102 is energized to inter-connect conduits 96, 98 to connect chamber 88b to inlet manifold vacuum. Diaphragm 90 is moved upwardly against spring 94 to open throttle 14. As the engine reaches a predetermined speed switch 30 opens to de-energize coil 34 so that switch 32 opens to disengage the clutch 24 so that pump 20 and fan 22 commence rotation. Simultaneously relay 48 renders contact breaker 52 inoperative allowing contact breaker 56 to advance ignition and coil 102 is de-energized causing throttle valve 14 to return to the normal idling position. In modifications the coolant temperature acts on elements 116, Fig. 2 or 154, Fig. 3 to cause throttle opening at low temperatures. In further modifications an element closes a choke valve (176) Fig. 4 (not shown) at low temperatures and the coolant is controlled by a thermostatically operated valve (180), Fig. 5 (not shown) to warm an inlet manifold (16).

Title: Improvements relating to preserving cooked potatoes
Inventor: RUGGERONE ARTEMIO PETER
IPC: B65B25/00
Filed: 1969-01-20
Abstract: 1,202,685. Preserving potatoes. L. M. SHAPOFF. 20 Jan., 1969 [19 Jan., 1968], No. 3203/69. Heading A2D. A food package comprises a sealed container of air-impervious material, cooked potatoes disposed therein, and a mixture of carbon dioxide and nitrogen gas in the container around the potatoes. Preferably carbon dioxide is present in amounts from 30 per cent to 70 per cent by volume, the balance being nitrogen. A small amount of oxygen, viz. 1 per cent to 5 per cent, may also be present. The sealed container may be refrigerated, at a temperature of 34‹F. to 55‹F. Prior to placing in the container, the cooked potatoes may be treated with a conventional preservative. The container is provided with a sealing flange and a lid, which during the displacement of air by the carbondioxide-nitrogen mixture, rests loosely on this flange, thus permitting the gaseous mixture to be injected at one end of the container, and air to be withdrawn from the other. The lid is then sealed to the container, and the latter refrigerated.

Title: Improvements in or relating to optical instruments for measuring distances and heights
IPC: G01C3/30
Filed: 1948-02-04
Abstract: 637,144. Tacheometers. COOKE, TROUGHTON, & SIMMS, Ltd., TAYLOR, E. W., and HOGG, F. B. R. Feb. 4, 1948, No. 3308. [Classes 97 (i) and 97 (ii)] In a tacheometer in which an achromatic wedge system is placed before one half of a telescope objective to produce two relatively displaced images of a distant staff, the separation of the wedges is adjustable by a micrometer device to vary the displacement of the images, the extent of the adjustment being directly proportional to the image shift produced thereby. By this means the use of a staff divided longitudinally with a scale on one side and a vernier on the other is facilitated. As shown, the wedges 7, 17 are mounted in a split collar 1 which can be attached to the objective mount of a telescope by a clamp 2. The wedges cover half the objective, a septum 20 absorbing stray light, and the wedge 17 is fixed while the wedge 7 is mounted on a slide 4 moved axially in a groove 3 in the mounting by a pinion 10 engaging a rack 9 fixed to the slide. By this means the image of the vernier on the staff may be adjusted to coincide with an image of a scale division, the range movement corresponding to this adjustment being read on a scale fixed to the pinion 10. Alternatively, the wedges may be built into the telescope.

Abstract: 534,428. Sewing-machines. FAIRWEATHER. W. C. (Singer Manufacturing Co.). Feb. 22, 1940, No. 3320. [Class 112] Oil, supplied by a pump to a conduit 22, passes around the hook shaft 17 by an annular space 24 into a chamber 26. From the chamber it passes into an eccentrically located annular space 28 and into a bore 30 in the hook shaft containing a removable filter 34. Oil leaves the filter by passages 36 and is transferred to the spool case race 40 by passages 39 and surface 41. The end of the chamber 26 is partly closed by means of an apertured disc valve 44 which can be turned to vary the oil leakage from the end of the chamber. In place of the disc, a conical ended screw may be used as a valve.

Abstract: 980,895. Mechanical seals. C. A. PARSONS & CO. Ltd. Dec. 9, 1963 [Jan. 30, 1963], No. 3874/63. Heading F2B. In a sealing arrangement for a rotary shaft 1 extending through a wall 2 of gas-filled chamber 3 in which a sealing ring 5 is urged into contact with a collar 4 on the shaft and sealing liquid, for example oil, is supplied to the sealing face 5a, contamination of the gas by sealing liquid flowing along the shaft is prevented or reduced by stationary radial baffles 9 spaced around the shaft. In the embodiment shown in Fig. 1, the baffles 9 have a small clearance with the shaft and two sets are arranged in series axially. A further baffle 10 having a small clearance with the collar 4 is provided in the ring 5 which is pressed towards the collar by fluid pressure and/or springs (not shown). Sealing oil fed from a space 7 and through a duct 6 to the sealing face 5a flows both radially inwards and outwards across the face. Sealing oil trapped by the baffle 10 is drained through outlet 14 whilst that passing the baffle is stated to be atomized in the space 8 by rotation of the shaft, separated out by contact with the baffles 9 and drained through outlet 12. In other embodiments, Figs. 3 and 4 (not shown), the sealing ring 5 contacts the side of the collar 4 remote from the chamber 3 and the baffles 9 are spaced around and have a small clearance with the periphery of the collar.
