Patent GB-1041789-A (GB)
Title: Process for producing modified polyesters
IPC: C08G63/66
Filed: 1964-05-29
Abstract: A polyester is prepared by mixing together an aromatic dicarboxylic acid or a C1- 4 alkyl ester thereof, a glycol, and a monoglycidyl ether <FORM:1041789/C3/1> where R is an alkyl, aryl, or alkaryl group of 1-18 C atoms and n is 1-10, and heating the mixture until it is highly polymerized. The monoepoxy compound preferably amounts to 1-35 mol. per cent of the acid component, and may be used in conjunction with a diepoxy or polyepoxy compound, preferably amounting to 0.001-1 mol. per cent of the acid.  Suitable aromatic dicarboxylic acids are terephthalic and orthophthalic acids, and suitable glycols are aliphatic and alicyclic diols containing 2-10 C atoms.  The monoepoxy compound may be the glycidyl ether of the monomethyl, ethyl, butyl, phenyl or benzyl ether of ethylene glycol, diethylene glycol or triethylene glycol. Suitable polyepoxy compounds are the diglycidyl ethers of ethylene trimethylene, tetramethylene and hexylene glycols, and of bisphenol A and hydroquinone, diglycidyl ether, 1,1,3-tris(glycidyloxy)-butane, 1,2-bis(2-methylglycidyloxy)ethane, 1,8 - dimethoxy - 2:3, 6:7 - diepoxyoctane, 1 - epoxyethyl - 3,4 - epoxycyclohexane, and 4,4-bis(p-glycidyloxyphenyl)-valeric acid glycidyl ester.  There may also be added catalysts for the transesterification and polycondensation reactions, e.g. the acetates of lead, calcium, cobalt11, manganese11, antimony, and zinc, zinc oxide, cadmium oxide, lithium oxalate, and antimony trioxide, colour stabilizers, e.g. phosphoric or phosphorous acids or esters thereof, and delustring agents, e.g. TiO2. The ester interchange is preferably conducted at 100-280 DEG  C. and the polycondensation at 200-350 DEG C., at less than 10 mm. Hg.  The monoepoxy modifier may be added before (preferably) or after the ester interchange step. In examples terephthalic acid-ethylene glycol polyesters are modified with butoxyethyl glycidyl ether (or isopropoxy- or methoxy- or phenoxy-ethyl glycidyl ether) alone or with the diglycidyl ethers of butylene glycol, or glycerol, in the presence of lithium oxalate or antimony trioxide, and zinc acetate or cadmium acetate.

Title: Improvements in and relating to copying lathes
IPC: B23Q35/10
Filed: 1951-10-02
Abstract: 710,887. Copy-turning. ISLER, F. Oct. 2, 1951 [Oct. 5, 1950], No. 22884/51. Class 83 (3) In a copying lathe for machining piston rings &c. a cam is used to move a rocking tool holder, and a counter cam, mounted coaxially with the first cam, and rotatable therewith and having a shape which is a negative image of the first cam, operates through a spring-loaded lever to balance or compensate the pressure of a tool-holder rocker-arm on the camshaft whereby the bearing load of the shaft during machining is kept constant. A stack of rings 2, Fig. 8, mounted on a mandrel is held between positioning means 41 on the lathe spindle and a tailstock centre 43. Roughing and finishing tools 1a, 1b, respectively, are held on a lever tool-rest 3, Fig. 1, rocking about a pivot 6 on a transversely adjustable slide 7. The latter is carried on a longitudinally adjustable saddle 12 which is provided with pivots 11 for an intermediate lever 10. This lever has an adjustable fulcrum 14a which bears against the flat underside of the tool rest and transmits a copying movement thereto from a cam 18 and roller 16, the latter provided on the lever 10. Adjustment of the tool slide to and from the work by the screw-spindle 15 varies the diameter of the work and the effectiveness of the intermediate lever 10. The fulcrum 14a of the latter may also be adjusted to vary the effect of the cam 18 by adjusting the screw 13. In order to balance the action of the cam 18 and spring 9, which keeps the follower parts in contact with the cam, one or more counter cams are arranged on the shaft 19. Two counter cams 22, Fig. 3, are provided in the example described, one on each side of the main cam 18. Decrements on the balance cams equal the increments on the main cam and the former have follower rolls 26 on levers 24 pressed against the cams by springs 27 ; the total effect of these springs equals that of spring 9. Lathe main features.-A self-contained twofeed pole-change motor 28, Fig. 5, drives through belt gearing 29, 32, a shaft 33 which extends lengthwise of the machine to drive through further belt gearing 34-37, Fig. 7, the main spindle of the machine. The cam-shaft 20 is driven by gearing 38-40 from the main spindle and further change-speed belt pulleys 45, 48, Fig. 5, drive feed gearing 49, 50, 54, through a clutch 51 for a worm and rack-and-pinion drive to the tool saddle. The main spindle is started by moving a lever 64 which, through jockey pulley 36, tightens the belt drive 35. Fig. 7. The tool slide is moved to the extreme right hand position where the slow feed and slow spindle drive is engaged. As the roughing tool finishes its operation and the finishing tool commences cutting, a stop 66, Fig. 5, on the saddle, engages a trio 67 which automatically increases the speed of the motor 28 and thus increases the snindle sneed and feed. A stop 68 finally engages lever 65 to throw out the clutch 51 in the feed train.

Title: Apparatuses for detecting phase shifts
IPC: H02P29/00
Filed: 1976-06-04
Abstract: 1524475 Detecting phase angle changes; monitoring motors SCANIAINVENTOR AB 4 June 1976 [6 June 1975] 23223/76 Heading H2K  In a circuit for detecting changes in the phase angle between current and voltage on a line 3, 4, 5 a constant-amplitude A.C. signal in phase with the current is derived by oppositely-poled parallel diodes Dl, D2 in the current path, and a similar signal in phase with the voltage is derived by oppositely-poled parallel diodes D3, D4 in a path between two of the line conductors or between one line conductor and a reference (e.g. artificial neutral) point. The current and voltage signals are detected (e.g. by switching amplifiers F1, F2) and supplied to an exclusive- OR gate G, the pulse train output of which has a mark-space ratio dependent on phase. A first, short time constant, smoothing circuit R8, C1, R9, C2 derives a D.C. voltage a representing the phase and able to follow changes thereof quickly, whilst a further, long time constant, smoothing circuit R10, C3 derives a voltage b which follows changes in phase more slowly. Amplifier F3 compares the voltages a, b from the two smoothing circuits and provides a first output level when a<b and a second level when a>b, each transition from one level to another thus corresponding to a change in phase. The circuit may be used to detect whether several changes of phase occur in rapid succession, e.g. due to a fan 1 going in and out of stall repetivively. Each transistion from the first to second level adds an increment of charge to a capacitor, and if a number of such transitions occur close together the capacitor voltage will exceed a reference (P), thus switching on a transistor TR to operate a protective relay RL and l.e.d. LD.
