Abstract: 715,927. Bearing liners. GLACIER METAL, CO., Ltd. May 26, 1953 [May 26, 1952], No. 13262/52. Class 12(1) [Also in Group XXII] In an obliquely split connecting rod, the circumferential profiles of half bearing liners 1 are so formed that bearing surfaces fitting closely to the journal over oppositely disposed quadrants A. located on the line of thrust, are separated by clearance areas B adapted to provide wedge spaces for promoting maintenance of an effective oil film. The load bearing area is from 60 degrees to 90 degrees in angular extent. In one method of making the liner, it is held in a semi-circular cavity 2 in a block 3 and the profile having quadrants A and B formed by means of a suitably shaped broach. Alternatively, two borings may be made from centres C and D. In a further modification additional metal is added to the semi-cylindrical recess, preferably by electro-deposition, so that the liner becomes deformed in way of the quadrant B when inserted in the recess; a simple boring operation may then be performed.

Abstract: 711,579. Electromagnetic switches; thermal switches. PREH, W., and PREH, A., [trading as PREH ELEKTROFEINMECHANISCHE WERKE J. PREH NECHF]. May 27, 1952 [Sept. 21, 1951; Feb. 4, 1952; Feb. 18, 1952], No. 13459/52. Class 38(5) [Also in Group XXXV] In an arrangement for regulating temperature pressure &c. movement of (say) a thermal element such as an expanding rod 3 is transmitted to a magnetic blade 15 so that this moves between two contacts 221 and 22<SP>11</SP> in series respectively with electromagnets 24<SP>1</SP>, 24<SP>11</SP>; on engaging, say, the contact 22<SP>11</SP> a circuit is completed through the electromagnet 24<SP>11</SP> which serves first to reinforce the contact and then to attract a second magnetic blade 29, Fig. 4, controlled by a dead-centre spring 32, so that this snaps over, breaking at 31<SP>1</SP> the circuit to the magnet 24<SP>1</SP> and also the circuit to the temperature-controlling consuming device V and preparing at 31<SP>11</SP> the circuit of the electromagnet 241. The thermal element now moves in the opposite direction till the blade 15 engages the contact 22<SP>1</SP> when the above' prepared' circuit is completed, causing reinforcement of contact 22<SP>1</SP> and the snap back of switch blade 29 to its original position. The expanding tube 3 acts through a less expansible rod 4 on a series of multiplying levers the final lever 10 of which act on an .arm projecting sideways from the blade 15 near its lower supported end. The lever 10 pivots about a fulcrum on a beam 12 which pivots about a pin 18 or 19 and is adjustable by a screw 17. The switch blade 29 is arranged behind the blade 15, Fig. 2, and both blades 15, 19, move between the poles 25<SP>1</SP>, 261 and 25<SP>11</SP>, 26<SP>12</SP> of the two electromagnets. The switch blade 29, Fig. 5, consists of a leaf spring arranged between two magnetic stiffening plates 65 which spread apart at the top and have apertures for the passage of the actual contact 30. In a modification, Fig. 8, the screw 17, which adjusts the temperature setting by determining the position of the beam 12, is rotatable by a knob 45 which can also move downwards relative to the screw by means of a pin and slot connection. This downward movement causes a cam 56 to move a spring contact 58 into engagement with a fixed contact 59 so closing a master switch and also forces outwards a spring 60 which has been holding the contact 21 against the contact 22<SP>1</SP> freeing the contact 21 for operation as previously described.

Title: Improvements in lubricating oil compositions
Filed: 1943-08-20
Abstract: The viscosity index of a mineral lubricating oil is increased by incorporating therein 0.5 per cent. to 5.0 per cent. by weight of an oil-soluble linear polyester reaction product of a glycol and succinic acid or an alkylated or alkenylated succinic acid, the polyester having a molecular weight between 5000 and 25000. Glycols mentioned are betadodecyltetramethyleneglycol, hexamethylene glycol, decamethylene glycol and octadecane-1,12-diol while the acid mentioned is the "triisobutylene succinic acid" obtained by alkylating succinic acid with triisobutylene.  In an example the polyester obtained from decamethylene glycol and "triisobutylene succinic acid" is added to mineral lubricating oil.  Specifications 470,580 and 484,964 are referred to.ALSO:The viscosity index of a mineral lubricating oil is increased by incorporating therein 0.5-5.0 per cent by weight of an oil-soluble linear polyester reaction product of a glycol and succinlc acid or an alkylated or alkenylated succinic acid, the polyester having a molecular weight between 5000 and 25,000. Suitable alkylated succinic acids, of general formula HO2CCH2CHR1CO2H where R1 is an alkyl radicle, may be prepared from the dibromide of an alpha-olefin through the dinitrile or by condensing malonic ester successively with an alkyl halide and chloracetic ester followed by decarboxylation.  Alternatively, these acids may be prepared by reacting an unsaturated hydrocarbon with maleic anhydride.  Thus "triisobutylene succinic acid" is prepared by reacting triisobutylene with maleic anhydride.  Suitable glycols of the alpha-omega type may be prepared by the reduction of the esters of corresponding alpha-omega dibasic acids, while glycols with a side chain can be made by reduction of esters of the alkylated succinic acids described above.  Thus beta-dodecyl tetramethylene glycol is made by the catalytic hydrogenation under pressure of the diethyl ester of "triisobutylene succinic acid."  Other glycols mentioned are hexamethylene glycol, decamethylene glycol and octadecane-1,12-diol. The formation of the polyesters may be effected by heating equimolecular quantities of the alkylated succinic acid and the glycol together with vigorous agitation and simultaneous contact with a stream of dry inert gas such as nitrogen or carbon dioxide.  In an example, decamethylene glycol and triisobutylene succinic acid are heated together.  Dry hydrogen is bubbled through the molten mixture which is stirred rapidly.  The product is dissolved in mineral lubricating oil. Specifications 470,580 and 484,964 are referred to.

Title: Glass of character control circuit for editorial correcting typewriter
IPC: B41J5/38
Filed: 1968-03-21
Abstract: 1,215,525. Selective signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 21 March, 1968 [17 April, 1967], No. 13708/68. Heading G4H. In a system for editorially controlling an automatic typewriter by data read from a record, e.g. punched paper tape, means are provided whereby an operator can cause the typewriter to stop immediately a character or control signal belonging to a selected group of characters or control signals, is read from the record. For example, if the selected group of characters contain all the numbers, then typing will proceed automatically, line after line, until a number is read from the record, whereupon the typewriter immediately stops without typing the number. The operator can then either depress a " go " key, whereupon automatic typing recommences, or he can type data on the keyboard, and then press the " go " key. As described there are eight groups of classes, listed on Fig. 2 against associated leads on which signals appear when characters or control signals belonging to the class are read 58 from the record. Those classes that are to be effective in stopping the typewriter are selected by the operator by closing appropriate ones of keyswitches 41 to 48, Fig. 3. Then, when a character or control signal in a selected class is read from tape an associated trigger (e.g. 126, Fig. 3) is turned on to activate a change detector 128, which, if a switch 40 is in its upper " in line " position, stops the typewriter. If the switch is in its lower " C/R " position then only carriage return signals stop the typewriter. Means may be provided whereby characters or control signals can be transferred from class-to-class. For example, the apostrophe is normally regarded as a punctuation mark (class 3), but if a switch 142, Fig. 2, is closed, it is then regarded as a letter (class 1).

Abstract: 1467622 Agricultural crop pick up and stack forming vehicle SPERRY RAND CORP 4 April 1975 [5 April 1974] 13865/75 Heading B8E [Also in Division G1] A trailer 12 having mutually pivotable frames 14, 16 has, Fig. 4, a crop pick up 52, a vertical conveyer 46 and a horizontal conveyer 54 to load a platform 70 having an enclosure 72. A roller 276, Fig. 6, of packing means 66 is reciprocated along a raisable frame 72 to compress the crop to progressively form a stack. The end walls 342, 348 of the frame 72, Fig. 6, are of less depth than the side walls 264, 266 and have pivoted extensions 348, joined by cables 360 so that the roller 276 depresses each extension in turn at that end of its movement thus raising the other end to force back any crop into the stack. Discharging means for the conveyer 54 comprises a flexible floor 250, Fig. 7, attached at 256 to a carriage 258 mounting and moving the roller 276 and wound on a cylinder 252 tensioned by a spring 274 to wind up. As the conveyer 54 and floor 250 are narrower than the trailer 12 a spreading device 366, Fig. 14, is provided to ensure an even deposit of crop comprising sweeping tines 368 pivoted at 372 on the carriage 258 and secured for a sweeping action on an arm 374 which by rollers 384 engages: a track 382 to reciprocate the arm as the carriage moves. With the frame 72 initially on the platform 70, Fig. 17, the trailer is advanced to pick up crop which is fed on to the flexible floor 250 which with the conveyer 54 and roller 276 advance to the right with the crop retained on the floor 250. As the roller 276 returns, Fig. 20, with the floor 250 the crop is discharged into the frame 72 as the roller compresses a previous layer. As the frame 72 fills a density detector (Group G) operates a valve to cause a ram 116, Figs. 1, 2, to raise the frame to allow continued stack formation. The conveyer 54 and telescoping doors 190 rise with the frame 72 until the Fig. 24 position is reached and the spreader 366 is then stopped to allow the formation of a domed top to the stack. When loading is completed the frame 72 is raised clear of the stack, Fig. 2, the frame 16 is tilted down by a ram 424 and the stack is unloaded on to the ground by a lug on a conveyer endless chain 430 and advance of the trailer. A reversing of the conveyer and trailer movements can reload a stack for later transporting.
