Title: Improvements in and relating to the regeneration of waste rubber
IPC: C08J11/12
Filed: 1942-01-30
Abstract: 555,643. Reclaiming rubber. NORTH BRITISH RUBBER CO., Ltd., and JOHNSTON, A. Jan. 30, 1942, Nos. 1311 and 2814. Drawings to Specification. [Class 70] Vulcanized rubber is reclaimed by heating it to 300-700‹ F. by hot inert flue or exhaust gases, and cooling in an inert atmosphere. The product is readily milled and fibrous material in it becomes carbonized. The rubber cut into segments is enclosed in perforated cylindrical containers and passed through a tunnel in countercurrent to a stream of flue gases at a temperature of about 475‹ F. The containers are discharged through an air-lock supplied with steam. Alternatively, the heating may be effected on perforated trays in an oven, hot gases being passed over each tray. Steam pipes are fitted to the shelves to discharge steam on to the rubber for cooling prior to discharge. Steam may be passed at intervals over the rubber during the heating so as to obtain separation of parts which are all rubber from rubber mixed with fibrous materials. The parts become separable by hand and may be separately milled or subjected to further heating.

Abstract: 230,225. Smith, F. Jan. 21, 1924. Vibration-dampers. - A vibration-damper for motor vehicles, adapted to act in one or two directions as required, comprises a lever B and integral brake-band A operating on a drum F' on the chassis, the lever being constructed to house a tensioning spring F and a bolt G which carries a nut L adapted to engage the spring F to put a restraining action on the rebound movement of the suspension spring, and a further element adapted, if required, to put a restraining action on the compression movement of the spring. The lever B is connected to the axle. The nut L screwing on the bolt G carries a finger U, Figs. 1 and 13, notched to engage an indicator X on the lever, the indicator being formed with a series of grooves W the spaces between which preferably correspond to two revolutions of the nut. The indicator is sufficiently flexible to enable the finger U to be forced out of engagement therewith by hand. The indicator provides means for comparing the rebound restraint on all the suspension springs so that it mav be made uniform. The element for applying restraint to the compression movement comprises a nut M carried by an externally screwed boss N of the nut L. The nut M is held in adjusted position by a spring catch S which engages a series of spaced recesses in the face of the nut M, the nut M and lever B being preferably formed with inclined faces P, R arranged to limit the movement of the nut to half a revolution. The amount of restraint put upon the compression movement of the suspension spring depends on the play between the nut M and lever B so that this restraint may be varied until, at its maximum, it equals the rebound restraint. Notches Y on the nut M and a projection, not shown, on the lever serve to indicate the position of the nut M. The head of the bolt has bevelled faces G<2> engaging the lug H through which it passes. The brake band is provided with a loose lining 3, Fig. 7, formed with oblique lubricant grooves terminating short of the sides of the lining the ends of which are respectively formed with an interengaging tongue 5 and cut away portion 4.

Title: Improvements in or relating to loom weft fork motions
IPC: D03D51/34
Filed: 1927-01-20
Abstract: 264,858. Maschinenfabrik R³ti vorm. C. Honegger. Jan. 21, 1926, [Convention date]. Weft-replenishing mechanism. - In centre weft-fork motions for stopping the loom in the absence of weft or for initiating weft-replenishment, the weft-fork is periodically woven into the fabric and mechanically withdrawn therefrom. When weft is absent, the weft fork is not retained in position but falls to initiate stoppage &c. The weft fork 1, Figs. 1 and 12, comprises a number of curved prongs on a sleeve member 3 rotatable on a wire holder 5. The fork is normally held in the position shown by a spring 6, or separate prongs may be controlled by individual springs. The wire holder is mounted in an oscillating member 9 pivoted to a carrier on the breast beam. The member 9 is operated by a cam 15 on a spring-controlled shaft 14, which is oscillated by a strap 19 secured to a disc on the shaft 14 and connected by a spring 19<1> to the lay 11. In operation the weft fork is raised by the member 9 till a projection 5<1> engages the fabric. When a weft has been inserted and beaten up, it holds the weft fork in its raised position. If weft is absent, the weft fork is allowed to fall by a notch in the cam 15. The cam is thereby held against furtherrotation, and a bar 26 pivoted eccentrically on the shaft 14 is brought to a standstill, thereby effecting stoppage or weft replenishment. When the shed is changed after several picks, or when the wefts do not lie closely to one another, a weft fork having separate prongs individually controlled by springs is employed. In some cases, a weft fork having a single prong is used. The invention is applicable to fast-reed and to loose-reed looms.

Abstract: 909,984. Code telegraphy. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1961 [Jan. 21, 1960], No. 2054/61. Class 40 (3). The invention provides an apparatus which produces correctly spaced pulses in response to the reception of jittered pulses. In the embodiment described, which uses an equal unit code, the duration of the theoretical arrival of successive code elements is divided into twelve instants t 1 -t 12 , and a signal element arriving at t at terminal 1 gives rise to a corresponding signal element at t 11  at terminal 2. The circuitry uses storage pulse amplifiers. These units are cocked by the reception of a cocking pulse-or by the simultaneous reception of more than one cocking pulse-and give an output pulse if at a later time a firing pulse is applied to a firing terminal. General operation, Fig. 1. A signal element pulse arriving at t cocks storage amplifier 3 and also feeds into unit 4. This unit is started by a pulse q at t 3  and is so arranged that after the reception of the start pulse, it emits a pulse at the first of the instants t 1  or t 7  following the instant t. This pulse, at t 1  or t 7  passes to a storage pulse-gating unit 18, and acts as a start pulse for it, while pulse q at t 3  acts as a stop pulse. Unit 18 emits a pulse at t 4  in response to a pulse from unit 4 at t 1  and a pulse at t 10  in response to one at t 7 . The pulses at t 4  or t 10  fire storage amplifier 3 which, if previously cocked, gives an output pulse, this pulse cocking storage amplifier 16. Amplifier 16 is fired by clock pulses at t 11  so that output pulses at t 11  appear at terminal 2 in response to jittered input pulses at t at terminal 1. The operation of units 4 and 18 is given in detail in the Specification with reference to Figs. 5, 6 and 7 (not shown). Specifications 877,777 and 909,985 are referred to.
