Title: Improvements in or relating to machines for carving designs in pile fabrics
IPC: D06C23/00
Filed: 1957-12-03
Abstract: 841,394. Finishing fabrics. CABIN CRAFTS Inc. Dec. 3, 1957 [Dec. 19, 1956], No. 37613/57. Class 42 (1). A machine for cutting designs in pile comprises a table 10 having an aperture 17 beneath which a rotating feed wheel 16 is located, means for raising the feed wheel so that a part of its periphery projects through the aperture to cause a ridge in the pile while the latter is being fed over the table by the wheel, and a rotating cutter positioned above the aperture to cut the pile from the said ridge. The feed wheel 16 is mounted on a shaft 19 supported by a lever 12 pivotally mounted on axles 14 in arms 15 fixed to the underside of the table, the lever 12 being pivoted about the axles 14 by means of a piston and cylinder arrangement 44 in communication with a valve 50 which is opened or closed by the operation of a treadle at the lower end of a link 56, the feed wheel 16 thereby being raised or lowered. The shaft 19 is driven from a fixed drive shaft 26 by means of the chain and sprocket system 22, 20, 24 and 18, the sprocket 24 being mounted on a spring-controlled, pivotable lever 34, thereby being able to compensate for the change of tension in the chain 20 when the wheel 16 is moved, so that the latter can be raised or lowered without any interruption in its rotation. The rotary blade is supported on a mounting plate 62 above the aperture 17 and is driven from the motor 70 through the shaft 73, sprocket 76, chain 77 and sprocket 78, the latter being mounted on a shaft extending from the blade. A bracket having guide fingers 66 is screwed upon the housing of the blade and serves to guide the fabric and control the width of the cut. The motor 70 may also drive the shaft 26, a clutch 90 being incorporated in the drive so that rotation of the feed wheel may be stopped when necessary. A vacuum nose 96 may be provided adjacent the blade to draw off pile cuttings. In a modification of the device, a second movable sprocket 24 is mounted on the opposite side of the table from that on which the first is mounted, so that the tension imposed on the chain 20 is symmetrical with respect to the sprocket wheel 18, and there is less likelihood of the latter rotating due to the raising or lowering of the feed wheel 16.

Abstract: 1437926 Vehicle control systems DAIMLER-BENZ AG 29 Aug 1974 [6 Sept 1973] 37823/74 Heading B7H A motor vehicle includes an alarm system comprising a plurality of alarm lamps for indicating specific defects, a central alarm lamp 13 which lights when any of the other lamps light and a device for increasing the pressure required to move the accelerator pedal 1 or 2 when a defect is sensed. In the particular embodiment the vehicle has accelerator pedals 1, 2 for forward and reverse movement interconnected by a lever 3 pivoted at 4. A further lever 5, also pivoted at 4, is connected to a spring loaded piston 14 whose movement is controlled by compressed air or hydraulic fluid supplied via an electromagnetically actuated valve 9. When a defect is sensed lamp 13 lights actuating a delay relay 12 which, after approximately 3 seconds, energizes electromagnet 11 to move valve 9 and vent cylinder 6. As spring 7 urges piston 14 to the right lever 5 engages lever 3 thus increasing its resistance to movement. Correction of the defect extinguishes lamp 13 and after a delay of about 1 second the valve again connects cylinder 6 to the pressure source. Resistance to movement is never sufficient to immobilize the accelerator pedals.

[Also in Division G4] A noisemeter comprises an integrating circuit 5 which includes a detector circuit 32, a storage condenser 46, a potential source 36 connected between the transistor base and one side of the storage condenser and a single pole, double throw, switch 37 whose switch arm 40 is connected to the other side of the condenser and is cyclically driven by a rotary drive 43 into alternate connection with the switch contacts 38, 39; so that repeatedly the condenser is first charged through the transistor output and then has its potential applied across a meter 6. A further driving arrangement 51 operates in timed relationship with the drive 43 to operate a condenser discharge switch 44 so that the condenser is discharged after each time period of its connection across the meter 6. The detector circuit 32 may incorporate a transistor 33 and the switch driving arrangements may be rotary driven cams. As described the complete noisemeter circuit includes a microphone 1, a linear feedback amplifier 2 of conventional design, a logarithmic attenuator 3 and a further linear amplifier 4. After being processed by these stages the noise signal is passed to the integrating stages of the invention, and the record obtained will be logarithmically related to the original noise input. This if of advantage since the ear is logarithmically responsive to sound energy. The charge and metering periods of the storage condenser are made sufficiently long for the meter record to be observed visually.

Title: Method of making bromine derivatives of aromatic compounds
IPC: C07C17/12
Filed: 1963-09-26
Abstract: Aromatic compounds having a plurality of non-condensed benzene nucleii in the molecule are converted into derivatives containing at least 4 bromine atoms in the molecule by treatment with bromine while at least partly dissolved in an olefine dihalide solvent comprising ethylene, propylene, butylene or isobutylene dichloride or dibromide or chlorobromide or a mixture thereof; the bromination is effected in the presence of a halogenating catalyst and, after the bromination, an addition of ethylene, propylene, butylene or isobutylene or a mixture thereof is made to the reaction mixture in an amount at least equimolar with the excess of bromine in the mixture. Specified halogenating catalysts are iron or aluminium or salts thereof and (or) iodine. The hydrogen bromide formed in the bromination may be oxidized to bromine by means of chlorine, which may be added in stages to the reaction mixture or mixed with the bromine or introduced into the reaction vessel with the bromine, but in any event a slight excess of bromine over chlorine is maintained until the end of the bromination, when sufficient chlorine may be added to make the molar ratio of chlorine to bromine about 1. The reaction mixture may contain 0.005-1% by weight of water, and the reaction may be effected at 10-60 DEG  C.  The products are useful for flame-proofing polyolefines and other plastics. Examples are given of the bromination of diphenyl ether to yield a pentabromodiphenyl ether, and reference is made also to the bromination of diphenyl and of di-, tri- and tetraphenylmethane.

Abstract: 846,222. Photographic shutters. AGFA A. G. Dec. 1, 1958 [Dec. 18, 1957], No. 38735/58. Class 98(1) A shutter has two concentric blade rings 2, 3, which rotate in the same direction to cause respective opening and shutting of the shutter blades, the actuating means which effects said rotation being subsequently retractable to its original position, for re-setting the shutter, without causing any further movement of the rings. The two facing edges of the rings have respective teeth 2b, 3b, and notches 2c, 3c in which respective friction springs 6, 5 engage. The rings are driven by a pawl 11, whose rear end is guided by a pin 11 a in a cam slot 12. Its forward end is pivotally attached to a block 7 moving within a recess 8 in the shutter housing. The block forms part of a setting ring 7b having a lever 7c tensioned by a spring 9. In the position shown the shutter is tensioned and set, but prevented from running down by the trigger 10. When this is released, the block is pulled in the direction of the arrow. The nose 11c of the pawl impacts one of the inner teeth 3b, causing the inner ring 3 to rotate, so opening the shutter, until spring 5 re-engages in the next notch. The movement of pin 11 a in the cam slot meanwhile pivots the nose 11c away from ring 3 to ring 2, when it impacts one of the outer teeth 2b, causing ring 2 to rotate and so close the shutter. A lever 7a controls the shutter speed. To re-set the shutter, block 7 is moved by means of lever 7c against the direction of the arrow, so that the pawl 11 is retracted without any further movement of the shutter rings.
