Patent GB-174728-A (GB)
Title: Improvements in and relating to milling cutter grinding machines
IPC: B24B3/02
Filed: 1920-11-01
Abstract: 174,728. Hunt, J., and Wild, T. C. Nov. 1, 1920. Milling-cutters, sharpening.-The teeth of a milling-cutter n are ground on their peripheral surfaces, whereby they are sharpened and backedoff in one operation, by a grinding-wheel e, the cutter being oscillated under the control of a templet t so that the teeth are ground to the correct form. The grinding-wheel is journaled in a bracket b mounted on a standard a, which also carries an inclined slide g movable by means of a screw g<1> and carrying a copy-disc or segment h, which acts as an abutment for the templet. The inclination of the slide is adjustable, and the slide is set parallel to the cutter-holder bed r. The cutter-holder k is mounted on a slide m carried by a bed and movable thereon to feed the cutter, and the bed is secured to a pawl o rotatable in an angle-bracket p carried by a slide q. This slide is movable on the inclined bed r and is pressed up towards the grinding-wheel by a spring s or by a weight. The bed r is movable along an horizontal bed j by rack-and-pinion mechanism operated by a hand-wheel j<1>. The pivot o carries the templet t, which is pressed against the copy-disc h. The teeth of the cutter are located by a finger 5. The cutter-holder, Figs. 4 and 5, comprises two side members y slotted at z and having projecting bosses 1 on which the cutter is mounted; the slots allow entry of the grinding-wheel to operate on the side faces of the cutter. The templet t is shaped to correspond with the form of the cutter, and as shown in Fig. 12, has sloping shoulders 4, which operate to move the cutter away from the grinding-wheel when the cutter is oscillated beyond the extent necessary to complete the sharpening. In operation, the cutter is oscillated, with the holder and the pivot o, by means of a handle o<1>, the templet moving the cutter to give the required shape to the teeth. The form of the teeth may be varied by extending or retracting the slide y by means of the screw g<1>; such extension or retraction causes a corresponding movement of the slide g and the parts carried thereby.

Title: Time lapse video magnetic tape recorders
IPC: G11B5/027
Filed: 1975-07-23
Abstract: 1507715 Time-lapse video magnetic tape recorder SONY CORP 23 July 1975 [7 Aug 1974] 30814/75 Heading G5R To check for proper recording operation in a time lapse video magnetic tape recorder in which some only of a continuous sequence of input video signals are selected at a predetermined rate and are recorded by rotary magnetic head assembly 2, 3 on a magnetic tape 1 moving relative to the head assembly at a speed too low to record all of the input video signals on the tape, means are provided to automatically monitor the recorded video signals during intervals between the intermittent recording intervals and to give an alarm and/or effect a remedial control if the replayed video signal level departs from a predetermined level. The output of a camera 100, receiving horizontal and vertical syncronized pulses from a generator 11, passes via an FM modulator 12 to a gate 19. The vertical syncronized pulses are counted by a counter 16 giving an output pulse on reaching a predetermined, but adjustable, count, e.g. one output pulse per minute. Flip-flop 25 is set by the counter output and thereby opens gate 19 so that the video signal passes therethrough to heads 2 via amplifier 20 and relay contacts C 1 , C 0 , flip-flop 25 being reset by the next vertical syncronized pulse so that just one field is recorded each time, and flip-flop 26 is set such that relay 21 is energized for one field interval whereby the field just recorded is replayed immediately by heads 2, the replay signal passing via relay contacts C 0 , C 2  to amplifier 22. If a recording malfunction occurs resulting in a low playback level, this is sensed by detector 23 to operate a visual or audible alarm 24, or stop tape transport and possibly exchange the tape. The apparatus may alternatively be arranged to record one frame, rather than one field, each time, and the monitoring of each recorded field or frame need not be immediate provided it is effected by the time the next field or frame is recorded. The output of counter 16 is recorded on the tape 1 by a head 18 and is also supplied to a circuit 10 receiving the output of rotation detector 9 and controlling tape drive at a constant rate by capstan motor 8. Tape drive may alternatively be intermittent. Rotation of heads 2 is synchronized with the vertical synchronized signals by a phase comparator 15 driving head motor 5 and having an input from a rotation detector 14 and divide-by-two circuit 13.

Title: Diisocyanate-modified polyester or polyesteramide elastomers
IPC: C08G18/42
Filed: 1950-12-19
Abstract: Synthetic elastomers are prepared by reacting a linear polyester or polyesteramide having a hydroxyl number from 40-100, preferably 50-60, and an acid number from 0-12 with 4,41-diphenyl, 4,41-diphenylene methane, dianisidine, 4,41-tolidine, 1,5-naphthalene, 4,41-diphenyl ether or para-phenylene diisocyanate or mixtures thereof, in an amount from 0.7 to 0.99 mols. per mol. polyester or polyesteramide.  The amino groups in the reactants used for the polyesteramide should not exceed 7.5 per cent of the total hydroxyl and amino groups in the reactants.  The Specification lists a large number of suitable starting materials, for the polyester or polyesteramide, including unsaturated acids and gives examples of starting mixes.  The elastomeric product may be cured by adding a polyisocyanate in such amount as to provide a total of from 2.8 to 3.2 -NCO equivalents per mol. of polyester or polyesteramide.  Curing may also be effected with other materials, e.g. alkyl ethers of hexamethylol melamine with a 2.4 dihalo naphthol as accelerator, or sulphur, benzoyl peroxide or tertiary butyl hydroperoxide if the polymer contains unsaturation.  In an example a polyester from adipic acid, ethylene glycol and propylene 1.2 glycol, of hydroxyl number 55.6 and acid number 3.1, was reacted with 4,41-diphenyl diisocyanate (0.96 mols. per mol. polyester) at 120 DEG  C. for 10 minutes and then, after pouring the reaction mixture into a tray, at 130 DEG  C. for 8 hours.  The modified polyester was then cured by reaction with 4,41-diphenyl diisocyanate to bring the total diisocyanate to 1.46 mols. per mol.  Eight additional examples are given using various amounts of diphenyl, naphthalene, tolidine, diphenylene methane, p-phenylene and dianisidine diisocyanates in the initial reaction with polyesters.  An example is also given using a polyesteramide and diphenyl diisocyanate.  The products are useful for tyres, belts, hose, sheet packing, gaskets, mats, dipped goods, tank linings, footwear and covered rolls.  Specifications 553,733 and 694,978 are referred to.
