IPC: B65H67/048
Filed: 1968-05-03
Abstract: 1275561 Continuous winding apparatus; spindle drive FAIRBAIRN LAWSON Ltd 2 May, 1969 [3 May 1968] 20996/68 Headings DID and D1J A thread winding apparatus has a mechanism for moving a filled thread package support from a winding station to a reserve station, and for moving an empty package support from a reserve station to the winding station, and two or more deflectors movable with the supports to intercept the thread extending from a supply source to the filled package support. Two spindles 11, 12 are mounted on a rotatable turret 10 and frictionally driven, the drive to the spindle at the reserve station (12 in Fig. 2) being disconnectable by moving a lever 24 (Fig. 4) by a fluid-pressureoperated lever 29, so that a full package can be manually removed and an empty support substituted. The thread is traversed by a camdriven guide 63 and is laid on the package support at the winding station by a roller 64. Winding speed is adjusted to maintain constant tension by means of an electromagnetic coupling, arranged to transmit extra torque when more than one spindle is rotating. Thread transfer. After a period determined by a pre-set timer, when next the thread traverse guide 63 reaches the end remote from the turret 10 and operates a micro-switch 77, a fluid-operated piston-cylinder assembly rotates the turret 10 through 180 (anticlockwise as shown in Fig. 2) raising the roller 64 away from the winding station by means of cam portions 96, 97 of the turret, the thread extending between spindle 12 and roller 64 being pulled against limb 93a of a deflector 92 (Fig. 7). Winding onto spindle 12 continues until the traverse reaches the turret end of the spindle, when the thread is pulled round corner 91a of deflector 92, is severed by knife blade 130, or an electrical resistance wire, and is caught up between pins 103 (projecting radially from the turret end of spindle 11) and a brush 104 (Fig. 10). Winding commences on spindle 11, and lever 29 is actuated to stop rotation of spindle 12, which is again brought up to speed before the next transfer, when the full package has been replaced by an empty support.

Abstract: 387,600. Plug cocks. OLSEN, F. V. A., 179, Vesterbrogade, Copenhagen. July 27, 1932, No. 21246. [Class 135.] Locking-catches.-In gas cocks having an axially-slidable operating handle which serves to lock the plug in the closed position, the cock plug 5 in this position is pressed firmly to its seating by the spring 19, the pressure of which, on the plug, is relieved upon axial outward movement of the handle 11 to release the plug preparatory to opening the cock. The handle is formed with a disc 12, and a transverse member 13 which engages a slot in the upper end of the plug for driving and is provided with downwardly-extending projections 14, 15 at its ends ; these projections are of unequal length and engage in recesses 14<1>, 15<1> in the upper edge of the casing in the locked position and, when released by outward axial movement, slide upon two tracks of the casing of different heights as the cock is opened. In this position although the plug is relieved of the pressure of the spring 19 it is still held to its seat by a second spring 20. If movement of the plug is continued up to 180‹ the handle falls again to a locked position with the projections 14, 15 in the locking recesses 14<1>, 15<1> in the casing. In a modification, locking projections of the same length and casing tracks of the same height are used so that the plug is movable through a complete revolution. The casing is completed by a cover 9, as shown.

Abstract: 647,761. Television. VALENSI, G. July 17, 1946, No. 21364. Convention date, Feb. 14, 1945. [Class 40 (iii)] [Also in Groups XL (a) and XL (c)] The saw-tooth voltage for a television system is generated by arranging the beam of a cathode-ray tube to trace a circular or spiral path on the anode, the construction of the anode being such that the current collected from the beam varies in saw-tooth manner. Fig. 2 shows an arrangement in which time-frequency pulses from a generator G are converted to sine waves by crystal filter F which is used to produce a circular trace by means of phaseshifting device D on the target plate p of a cathode-ray tube having an electron gun arranged to produce an electron image in the form of a fine line. The target plate p is provided with a circular slot f, Fig. 3, having a varying width so that the number of electrons from the beam which is always broader than the slot, reaching the anode a<SP>3</SP> varies in a sawtooth fashion producing a corresponding voltage drop across resistor R. The radius of the circle is adjusted to be equal to that of the slot by varying the potential across concentric electrodes L<SP>1</SP> and L2. In a modification, Fig. 3a (not shown), the target p is omitted and the anode a<SP>3</SP> is a resistive strip of metal b<SP>1</SP> on a , mica plate, so that the resistance between the point p, to which the resistor R is connected, and the point of incidence of the beam varies in a saw-tooth manner. The strip may be in the form of a spiral, Fig. 3 (b) (not shown), in which case a saw-tooth potential is applied to electrodes L<SP>1</SP> and L<SP>2</SP> at line frequency and the frequency of the voltage from generator G is a multiple of the line frequency corresponding to the number of turns in the spiral, also the strip is configured so that a uniform variation of resistance occurs despite the non-uniform writing speed of the beam. The resistive strip may be configured so that a triangular wave is produced, a sine wave being used as the deflecting potential applied to electrodes L' and L<SP>2</SP> in this case. Synchronizing receivers with transmitters. The transmitter and receiver may both be locked to the mains supply which is fed to the input of generator G. A standard frequency distributed over the telephone lines may be substituted for the mains frequency. Alternatively synchronizing signals may be modulated upwards to a frequency band which comes within a part of the video spectrum in which there is little energy. In this case the filter F is connected to the demodulator at the receiver.

Title: Electrical communication apparatus
IPC: H04L12/403
Filed: 1962-06-04
Abstract: 987,292. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 4,1962 [June 29, 1961], No. 21387/62. Drawings to Specification. Heading G4H. The description is similar to that in Specification 987,293 which is referred to but the sequencing arrangements of the mulcoms (field stations), to which the claims relate, differ. As described each mulcom includes a first counter HO all of which are advanced one step each time a mulcom starts to transmit and each of which causes its associated mulcom to start to transmit when an associated count-individual to that mulcomis reached. Each mulcom also includes a second counter LO. These counters are all reset each time a mulcom starts to transmit, and commence counting clock-pulses every time a mulcom stops transmitting. Thus if any mulcom fails to start transmitting (due to a fault) the count in the LO counters will rise to a level higher than normal and this is used to cause the next mulcom in the sequence to start transmitting, thereby by-passing the faulty mulcom. Specification 987,291 also is referred to.

Title: Improvements in or relating to new chemical compounds
Inventor: BOLDINGH JAN
IPC: A23D7/005
Filed: 1952-08-08
Abstract: The invention comprises the lactone of deltahydroxy dodecanoic acid. It may be prepared by dehydrating the acid or de-alcoholating an alkyl ester thereof.  The acid or ester may be formed by reducing the keto-acid or its alkyl ester with, e.g. aluminium isopropylate.  A number of preparations of the delta-keto- and delta-hydroxy-acids is given.  The lactone may also be prepared by directly oxidizing a -heptyl cyclopentanone using Caro's acid or a mixture of sulphuric acid and hydrogen peroxide; by isomerizing delta-keto dodecanol with sodium methoxide and acid; by oxidizing 1,5-dodecanediol, e.g. with copper chromite; by hydrogenating the lactone of delta-hydroxy a -b -dodecenoic acid; and by heating a mixture of water and a 2-heptyl-tetrahydropyrane under pressure in the presence of a dehydrogenating catalyst.  Preparations of these starting materials are also described.  In the examples: (1) delta-keto-dodecanoic acid is obtained by saponification and acidification of the ester obtained by condensing cadmium heptyl with glutaric acid monoethyl ester monoacid chloride.  This is reduced with aluminium isopropylate and the hydroxy-acid is lactonized by heating under low pressure.  (2) Hydroxyheptyl cyclopentanone, prepared from heptaldehyde and cyclopentanone, is dehydrated with oxalic acid to give heptylidene cyclopentanone. This is hydrogenated to heptyl cyclopentanone which is oxidized by Caro's acid to delta-dodecalactone.  (3) Heptyl cyclopentanone is oxidized with chromic acid in sulphuric acid to give delta keto-dodecanoic acid which is reduced as in (1).  (4) Delta-dodecalactone is prepared as in (2) using hydrogen peroxide in alcoholic sulphuric acid instead of Caro's acid.  (5) Delta-ketododecanoic acid is hydrogenated in NaOH solution and the resultant delta-hydroxy acid lactonized as in (1). Specifications 653,764 and 748,645, [Group VI], are referred to.
