Filed: 1973-06-29
Abstract: 1391157 Electrically driven vehicle CATERPILLAR MITSUBISHI Ltd 29 June 1973 [28 July 1972] 31158/73 Heading B7H An electrically driven industrial vehicle 1 has an induction motor 5 as its main motor which is supplied from a source of alternating current whose frequency may vary and which drives an hydraulic pump 27 and a torque converter 13 of the vehicle transmission via a gear means 9 which compensates for changes in the frequency of the A.C. supply to provide a constant predetermined speed of rotation of the inputs of the torque converter 13 and pump 27. As described, the frequency of the A.C. supplied to the motor 5 may be 50 Hz or 60 Hz and the gear means 9 is a two-speed sliding pinion gearbox having two output shafts 11, 26 each rotating at the same speed. The two gear ratios of the gear box 9 are chosen such that the rotational speed of the output shaft 11, 26 are predetermined and constant, even though the rotational speed of input shaft 11 varies when the frequency of the A.C. supply is changed. The rotational speed of the output shafts 11, 26 is also chosen to approximately the same as an ordinary diesel engine so that it is possible to change a vehicle designed to be driven as a diesel engine to an electrically driven vehicle without any change in design by merely using the motor 5 and gear means 9 instead of the diesel engine. In such a vehicle the motor 5 and gear means 9 drive a torque converter 13 which is successively connected to a transmission 15 controlled by gear shift 19, steering clutch 16, final drive 17 and sprocket 18. The vehicle may have endless tracks 3 or wheels (not shown). The motor 5 may be supplied with A.C. from aerial wiring or from a cable connected to an external source, the cable being wound up or unwound from a reel on the vehicle as the vehicle moves. Oil from the torque converter 13 is cooled in a cooler 21 by a fan 22 driven by an electric motor 23. The gear means 9 also drives an hydraulic pump 26 which supplies oil under pressure to an hydraulic system 29 which includes an hydraulic motor (not shown) for operating the cable reel and the operating mechanisms for a bucket 6. The oil in system 29 in a cooler 33 by a fan 36 driven is cooled by electric motor 35.

Title: Improvements in surface condensers
IPC: F28B1/02
Filed: 1929-10-16
Abstract: <PICT:0341124/III/1> <PICT:0341124/III/2> <PICT:0341124/III/3> In a single pass surface condenser comprising two or more compartments vapour to be condensed enters by a single inlet 1 and is caused to flow in separate streams through the compartments transversely of cooling tubes 2, and the length of the several streams and the cooling surfaces traversed thereby are arranged to increase as the mean temperature difference between the vapour and the cooling surface and the mean velocity of the vapour both decrease in order that an equal amount of condensation may take place in each stream. The condenser is divided into compartments by tube plates with suitable apertures; in downward flow condensers, the compartments are formed by baffles 7, Fig. 5.  The condensate drains away through port 5, and uncondensed vapour and gases are withdrawn through opening 6. The cooling water as it passes from inlet 3 to outlet 4 increases in temperature, and therefore the length of path in the condenser before the entering steam increases as the steam enters nearer and nearer the water outlet 4.  The outlet 6 may be placed in the space 21, and also the space 11 may be enclosed and provided with a separate outlet at the bottom.  The breadth of the condenser perpendicular to the plane of the drawings advantageously decreases towards the bottom. In the radial flow condenser shown in Fig. 8 baffles 26 and 28 with apertures 37 in the central tubeless space and baffles 27 and 29 with apertures 36 at the bottom are provided.  The outlet 6 opens into the central tubeless space.  Baffles connect the lower halves of baffles 26 and 28 to prevent steam directly reaching the bottom of spaces 32 and 33 and baffle 30 presents direct passage to outlet 6.  In another form of radial flow condenser, the steam is directed by baffles 26 .. 29, Fig. 10, having central apertures in the tubeless space and baffles 21 .. 24 opposite these apertures.

Patent GB-995057-A (GB)
Title: Improvements in or relating to the preservation of foodstuffs
IPC: A23L3/3517
Filed: 1963-08-13
Abstract: Foodstuffs, including harvested agricultural produce, are protected against microbiological spoilage by treating them with a chemical preservative comprising at least one compound having the general formula <FORM:0995057/A1-A3/1> wherein R is either heptyl or octyl, the normal esters being preferred, X is hydrogen, alkali metal such as sodium or potassium, or alkaline earth metal such as calcium and n is an integer equal to the valency of X.  The preservative which may consist of the above-defined heptyl and octyl esters in admixture with one or more of the corresponding methyl to hexyl (preferably propyl or butyl) esters, may be incorporated into the food during or after processing (i) directly, (ii) in the form of a liquid or dry surface spray, dip coating or dust, e.g. on fruits or vegetables during the growing season, (iii) by migration from the packaging media, ice or vapour used during storage of the food and (iv) by intravenous injection to an animal before slaughter. Concentrations of the preservative in the food of from 0.0001 to 0.1 weight per cent, preferably from 0.001 to 0.01 weight per cent, are suitable. Solutions having a concentration of 0.1% by weight of preservative in such solvents as propylene glycol, ethanol, corn oil and peanut oil may conveniently be employed. Branched chain ester e.g. iso-octyl, may be used instead of the normal esters.  The many foodstuffs particularly mentioned fall broadly into the following categories: fresh and processed meat, poultry, fish and crustace ; eggs; batters, pastry and other baked goods; dairy products such as cheese, yoghourt and sour cream; salad dressings; harvested fruits and vegetables; apple cider, and fruit juices and other soft drinks; and pickles. According to one of many examples, each of the esters from methyl to octyl, inclusive of p-hydroxybenzoic acid is separately dissolved to the limit of solubility in propylene glycol.  The glycol solutions are then mixed together and added to the limit of ester solubility to a 5% sodium chloride brine at 48 DEG F.  Haddock fillets are dipped into the brine for 10 minutes, drained for one minute and then stored at 48 DEG F. for up to 125 hours.  In the procedure of another example, half-sour cucumber pickles are preserved in the half-sour condition in a brine containing 10 parts per million of the heptyl ester of p-hydroxybenzoic acid. The Specification alludes to the following known preservatives: sodium benzonte, dehydro-acetic acid, calcium and sodium propionate, sorbic acid and its salts, biphenyl and o phenyl phenol.

Title: Arrangement for the measurement of forces
IPC: G01L1/02
Filed: 1957-10-11
Abstract: 871,074. Indicating-apparatus; dynamometers; pressure-gauges. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Oct. 11, 1957 [Oct. 23, 1956], No. 31870/57. Classes 106 (2) and 106 (4). A dynamometer comprises a load cell 1 and device for indicating forces absorbed thereby in which the restoring spring 13 is assisted by a supplementary restoring force which becomes smaller with an increasing deflection of the indicator. A force applied to the load cell causes pressure fluid to flow into the cylinder 5 and depress the piston 6 against the combined forces of the spring 13 and electromagnet 8, turning the pointer 16 over the scale 18 through rack-and-pinion. The arrangement is such that without a force acting on the load cell, the armature 12 rests against a plate 9 without exerting any upward pressure and the pointer 16 registers with the zero mark 21a. It is stated that, as an increasing force is applied, the magnetic restoring force falls off at a rate which compensates for the non-linearity of the response which would occur without it. In a second embodiment the spring 13 is replaced by a pivoted counterweight and the supplementary magnetic force is applied through a pulley fixed on the pivot of the counterweight.
