Abstract: 1454758 Working at specified temperatures KOBE STEEL Ltd 8 Nov 1973 [8 Nov 1972 13 Dec 1972 18 Dec 1972 19 Feb 1973] 51822/73 Heading B3V A hot forging process for carbon or low alloy steel involves initially subjecting the steel to heat treatment or plastic working; cooling it; and finally reheating it followed by hot forging at a temperature between 450‹ C. and the A c1  transformation point. The strength and toughness of the steel are claimed to be improved by this process. The initial treatment may involve forging the steel at a temperature between the A c3  and 50‹ C. below the A C3 , followed by an oil or air quench. Alternatively, the steel may be cold rolled or drawn to give a reduction of greater than 15%, or may be forged at a temperature above the A C3 . It is preferred to heat the steel quickly to its working temperature and hold it for a short time during working. In an example, A151 1045 steel was initially forged at 750‹ C., was water quenched, and then hot forged at 600‹ C. The initial forging can alternatively take place at 820‹ C. (which is above the A c3  of 793‹ C).

Title: Bearing control system
IPC: F16C27/08
Filed: 1975-11-25
Abstract: 1535163 Bearing control system ALFRED HERBERT Ltd 25 Nov 1975 [3 Dec 1974] 52167/74 Heading G3N [Alson in Division F2] A bearing control system for a fluid loadable bearing 1 produces an electrical signal relating to a measured parameter, e.g. shaft speed, which is used to vary the fluid loading on the bearing. Shaft 3 rotates in bearings 1, 2 housed in sleeve 4 which slides axially in body 5 but is prevented from rotation by dowel 6 in slot 7. Hydraulic pressure in chamber 13 varies the position of sleeve 4, and thus the outer element 3a of the bearing 1, in the direction of arrow A and thus varies the loading. The shaft speed is electrically measured by tachometer 16 whose output feeds control device 17 for proportional actuator 18 which controls the pressure valve 19 for chamber 13. Transducer 20 senses the pressure loading, shown on gauge 21, and gives feedback so that the pressure does not exceed a limit. An over-ride can be provided manually or from a numerical controlled machine tool to vary the limit. The parameter may also be load exerted on the bearing by a shaft. Alternatively bearing preload can be varied in accordance with cutting forces on the slide.

Abstract: 1,105,678. Testing of sheet filter materials. PORRITTS & SPENCER Ltd. 12 Aug., 1966 [10 Dec., 1965], No. 52687/65. Heading BIT. Sheet filter material, such as woven, knitted, felted or needled natural or synthetic fibres or combinations thereof, in the form of a sleeve 13 is enclosed in a transparent plastics tube 10 and tested by drawing gas therethrough with a pump 30, the gas entraining dust in a chamber 11 and any dust which penetrates sleeve 13 being collected by a fibrous pack filter 45. The variation in pressure drop across sleeve 13 is monitored using water manometer 49, and filter 45 is weighed to estimate the dust passing filter 13 per unit time or volume of gas, as measured by flowmeter 48. The amount of dust entrained by gas passing through chamber 11 is estimated either by light absorption at the lower end of tube 10 or by parallel tests using similar flow rates through standard sleeves 13 which retain 100% of the dust and are weighed. The test may also involve one or more operations in which sleeve 13 is cleaned, either by reversing the flow with valves 28, 36, 37, 40 or by shaking the sleeve with cam 22. The dust 12 in chamber 11 is agitated mechanically or by rotating auxiliary gas jets 50, 59 to facilitate entrainment by the main stream entering under baffle 60. Various flow rates are controlled by bleed valves 43, 56.

Patent GB-527760-A (GB)
Abstract: 527,760. Ticket-issuing machines. BACEDAHL, K. G. A. June 5, 1939, No. 16501. [Class 106 (iii)] In a ticket-issuing machine having ticket printing means the printing wheels are set by mechanism including a strip 59 moving on rollers and having perforations or embossments which engage with the setting members of the printing wheels. The strip 59 passes from rollers 57 to 58, is positively moved by a feeding roller 61, and is read as it passes between plates 71 by pins 79 on bellcrank levers 76. Setting members 83, 84 and 85 are provided with stepped portions such as 88 and 89 co-operating with levers 76 and are held up against the action of springs 91, 92 and 93 by a lever 94. The fare strip 59 is adjusted by a handwheel 109 which drives feed roller 61 and also operates indicator wheels 122, 124, and 125 which indicate the length of travel and class of the ticket about to be issued. A lever 130 is then operated. During the first part of its movement it actuates a pawl to lock the strip 59 accurately in its setting. In the next part of its movement it operates cam shaft 81 and causes the levers 76 to read the setting of the strip. On further movement of lever 130 lever 94 is rocked and members 83, 84, and 85 are freed to take a setting from levers 76. This setting is indicated on number wheels 105, 106, and 107. Printing wheels 180, 181, 182, 183, 184, 185 and 186 are set by connection with the indicating wheels 122, 124, 125, 105, 106, and 107. Paper strip from a roll 146 is led over a roller 155 to a printing platen 156 andthen passes to an exit 178 the ticket being severed by manually pinching the jaws 178 together. The ticket strip is led over the platen 156 together with a strip of carbon paper and on operation of a lever 174 a spring operated hammer is released which drives the strip against the printing wheels and marks the ticket. The used carbon strip is stored in the apparatus and serves as a negative print of each ticket in the order in which they were issued. The members 83, 84, and 85 also operate racks controlling the wheels of a totalizer counter which indicates the total value of the tickets issued by the machine. If a special fare is required which is not indicated on strip 59 the fare indicating and printing wheels may be independently set by keys 252. The strip 59 may be read by electrical contacts co-operating with the perforations instead of by mechanical means.

[Also in Division A2] A method of disconnecting the components of composite food pieces comprises moving the food pieces between downwardly depending flexible tines (e.g. of fabric reinforced rubber or plastics material) and a horizontal bed having upwardly projecting protuberances thereon by rotating said bed about a vertical axis to accelerate the food pieces centrifugally and receiving and removing the disconnected component parts of the food pieces from the periphery of the rotating bed. The method may be used to disconnect stones from the fleshy parts of cherries. A suitable apparatus comprises a rotatably mounted disc 5 having radially extending ribs 5a and 5b on its surface, three concentric rings of tines 10a and radially extending rows of tines 15b adjustably mounted above the disc 5 and a helical trough 3, around the disc 5. In use the food is passed from chute 30 to the centre of the rotating disc 5 and is moved centrifugally between the ribs 15a and 15b and the tines 10a and 15b which results in disconnecting the components of the food, to the trough 3. The mixture of disconnected components is discharged from the trough 3 to chute 4. The components are then separated e.g. by flotation means. The passage of the food across disc 5 and along trough 3 may be aided by introducing fluid (e.g. gas, water, brine) into the centre of the disc and into the trough. The number of rows of tines may be altered. The tines may be arranged in eccentric rows or spirally and may be rotated, vibrated or oscillated.

Distilled water is produced from sea water, or other saline solution, by contacting it in heat exchanger 3 with hot mineral oil, or other water-immiscible liquid, passing the heated sea water through a multi-stage flash evaporator 2 1  .. 2 n , and condensing the vapours evolved in the higher-pressure flash stages 2 1 , 2 n , 2 n+1 , by means of oil circulating through condenser tubes in these stages, and also circulating through a heater 8 and the direct-contact heat-exchanger 3 wherein the feed sea water is heated. Before the sea water enters heat-exchanger 3, it is preheated by passing it through the condenser tubes 4 of the lower-pressure flash stages. The condensate (i.e. distilled water) is collected in trays 6, and withdrawn from the lowest-pressure stage 2 n . The oil preferably has a higher density than water. The sea water flows upwardly in dispersed form through heat-exchanger 3 and the oil flows downwardly. The condenser tubes may be made of mild steel provided with an outer coating or paint.
