Patent GB-874957-A (GB)
Title: Improvements in and relating to winders, hoists and like lifting apparatus
Inventor: WOODLIFF GEOFFREY EDMUND
IPC: B66B1/12
Filed: 1956-12-19
Abstract: 874,957. Controllers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 6, 1957 [Dec. 19, 1956], No. 38752/56. Class 38 (3). [Also in Group XXX] In a mine hoist control, the position-responsive cam C3 performs a plurality of revolutions during a single wind, but operates the control gear 3 only whilst the cage is in the retarding zone of the level at which the cage has been selected to stop. Cam operation of control gear 3 (Figs. 1, 3).- The winding drum (via shaft 1) drives cams C1-C5 each corresponding to one of five levels at which the mine cage is to stop, and the corresponding cam followers F1-F5 selectively operate control gear 3 by means of lost-motion device 5, 6 and shaft 4. The cam followers F1- F5 are positioned by thrusters T1-T5 acting against weights W1-W5. Additionally, the winding drum drives selector switch 9 containing one set of contacts for each level. Operation.-The operator presses a switch to select the level required. This causes the following: switch 9 rotates; cams C1-C5 rotate, the cam followers being clear of their cams; the electric circuits of thrusters T1-T5 are " prepared "; and thruster TX swings shaft 4 anticlockwise (Fig. 3) to full speed for the winch. As the retardation zone of the level is approached, switch 9 operates to close the " prepared." circuit of thruster T3 so that the latter operates to swing F3 anti-clockwise into its operative position bearing upon cam C3. At the same time thruster TX is released so that shaft 4 is ready, under the influence of its weight WX, to follow the subsequent clockwise movement of F3 as the latter mounts the protuberance of cam C3. This clockwise movement of shaft 4 operates control gear 3 to stop the cage when the level is reached. Electrical circuit (Fig. 4).-The operator commences the wind by closing circuit 12-13 to energize coil TWX to operate thruster TX to swing shaft 4 anticlockwise to the full-speed position. The operator then closes (say) contacts LS3, thus choosing his level. When the associated retardation zone is approached switch 9, in its rotary movement, causes segment SC3 to make contacts S3. This energizes coil TW3 to operate thruster T3 to move F3 anticlockwise into operative position on cam C3. At the same time, thruster T3 opens contacts T3A to de-energize thruster TX. Then the cam C3 effects the final anticlockwise movement of shaft 4 to operate control gear 3 to stop the motor to bring the cage to a halt at the chosen level. As the motor stops it opens contacts IS to de-energize thruster T3, ready for the next choice of level. Specification 854,071 is referred to.

[Also in Divisions B6 and B8] A web 1 being continuously fed by two pairs of nip rollers 4 and 5 is intermittently rendered stationary between two rollers 6 and 7 by looping devices which include eccentrically mounted rollers 8 and 9. Rollers 6 and 7 are mounted to rotate freely on bearings (28, Fig. 8) and the bearings are seated on members (26) which are eccentrically mounted on driven shafts (6<SP>1</SP>). Screws (34) and (35) are used to adjust the eccentricity. The shafts (6<SP>1</SP>) are rotated at twice the speed of the rollers 8 and 9 via gears 18-22 and endless band and pulleys 23, 24. The rollers 6 and 7 have the effect of stretching and slackening the web twice per cycle of the looping devices, thereby avoiding excessive stretching and slackening of the web otherwise inherent in the operation of the apparatus.

Abstract: 1497758 Expanding pulley gear T B WOODS SONS CO 29 Sept 1975 [30 Sept 1974] 39741/75 Heading F2D The hub of a flange component 10 for an adjustable Vee-pulley has bearings 14, 15 each constituted by a relatively thin inner layer 24, 27 of dry bearing material and a relatively thick outer layer 33, 34 by which the inner layer is bonded to the unmachined bore 16, 17 in the pulley. The figureillustrates a method of forming the bearings so that no subsequent machining is necessary. Around each of a pair of concentric portions 19, 20 of the former are wrapped tapes 24, 27 such as P.T.F.E.-filled tape, bronze-filled strip, glass-filled laminate, &c., to form the bearing surface, and the flange component is located in an annular recess 21 in the former. The tapes, which are preferably etched or otherwise prepared for bonding with an epoxy resin, are held against the surfaces of the portions 19, 20 by vacuum applied through passages 25, 26, 28, 29, 30, and the annular spaces between the tapes and the bores 16, 17 are filled by injection of an epoxy or like material. Instead of the former 18 a sleeve component on which the pulley flange is ultimately to be slidably mounted may be used. The bores may be polygonal instead of cylindrical or, e.g. the bore 16 may be cylindrical and the bore 17 hexagonal. One construction of pulley to which the invention is applicable has both flanges slidable on a sleeve and urged towards each other by springs. Other constructions have one flange integral with a sleeve and the other movable either under spring loading or by manual adjustment, and another consists of a multiple pulley arrangement with spring-loaded flanges.

Title: Arrangements in telephone exchanges for the provision of special services such as diverting calls for absent subscribers
IPC: H04Q3/00
Filed: 1964-10-02
Abstract: 1,030,289. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 2, 1964 [Oct. 3, 1963], No. 40201/64. Heading H4K. To divert calls made to them in their absence' subscribers can dial their own number and a special code to set up a common translator so that when the translator is employed to terminate a call to the absentee subscriber a special service signal is produced to divert the call to an operator's position or to a recorded announcement. Absentee service is only afforded a subset in response to a request from that subset, the identity of the subset as dialled being compared with its identity as represented by a line identifier. The service is also conditional upon a sufficient class of service. The translator is common to the exchange and in response to a calling condition is instructed by a line identifier to forward the calling directory and/or equipment number together with associated class-of-service codes to a register. The register receives the dialled identity of a subscriber setting up an absentee service and, if the information qualifies, the register instructs a marker to set the translator to a condition such that any future application made to it in respect of this line's identity will produce an additional absentee subscriber code which guides the marker to set up a connection to an operator or a recorded announcement. When afforded the absentee service a subset is supplied with a characteristic dial tone as a remainder that calls are being diverted. To cancel the service a subscriber dials his own identity and a cancellation code to effect restoration of the translator. An operator can alter the class-of-service attributed to a line by dialling the line number and a code digit to indicate the new class. Once the translator has been set up it causes an acknowledgement to be reverted. This facility makes it necessary for the operator to dial a code following a line identity when an actual connection is required. The invention is said to apply to special services other than absentee subscriber service.
