Title: Improvements relating to the storage and transmission of data signals
IPC: G11B5/004
Filed: 1957-12-09
Abstract: 853,205. Driving magnetic drums. DIRKS, G. Nov. 4, 1958 [Dec. 9, 1957], No. 38146/57. Class 40 (2). [Also in Group XIX] A magnetic drum or disc for data storage has a latch holding it in a predetermined position and releasable under control of an incoming signal to allow it to rotate and thus record the data signal commencing at a predetermined point. In the embodiment of Fig. 1, an incoming data word from 16 is first recorded on a further and continuously rotating drum 1 by head 19 via switch 18 (thus recording may take place at any position in track 15), and is transferred to the drum 5 by re-setting 18 to the position shown and closing switch 22. Drum 5 is normally held with reference line 21 in the position shown by a latch 9 pivoted at 10 engaging a projecting key 8 on its shaft 6, a slippable friction clutch 7 being provided between shaft 6 and the continuously rotating shaft 2. When the data on 15 next reaches read head 23 after closing of 22, mono-stable flip-flop 25 is set and re-sets shortly after the word sensing has finished to set flip-flop 26 and hence open gate 27. At the next revolution the first signal of the word passes 27 to set flip-flop 28 and hence open previously-closed gate 33, and also to fire gas-filled valve 29 and through solenoid 14 release latch 9 and allow drum 5 to start rotating. Head 19 is so located downstream from 23 that the drum has reached the correct speed and reference line 21 the record head 35 when the data starts to arrive at 35 for recording. Valve 29 is selfextinguishing so that the latch falls back to stop drum 5 after one revolution has been completed. Fig. 2 shows an embodiment in which data words from tape 36 are to be recorded on the drum 5; the first signal of the word when read at 45 sets 44 to energize 14 and stop the normally-rotating drum 5 in predetermined position, and when read (rather more than one drum revolution later) at 46 re-sets 44 to start it rotating again, the data then being recorded by 35 commencing at 21 since a delay 50 is provided. Drum 5 may have a number of data tracks selected in turn for recording a number of data words without destruction of previously recorded words, or a read head on track 20 for readout before destruction may be provided. Data signals from record cards or paper tape instead of a magnetic drum or tape may be similarly recorded on drum 5. The Provisional Specification refers to the transfer of information from the drum 5 (Fig. 1) back to the main drum 1 to a predetermined position.

[Also in Division D1] A needled non-woven fabric of synthetic polyamide and/or polyester staple fibres having a denier of 10-50 is rendered suitable for use in the production of a tyre chafer strip by impregnating it with vinyl pyridine rubber and an incompletely condensed resorcinol formaldehyde resin. The weight of fibres, which preferably have a length of 60-80 mm., in the fabric may be 100-300 grams per square metre. The fabric may be dipped into the composition comprising vinyl pyridine latex and incompletely condensed resorcinol formaldehyde resin and dried at 110-120‹ C., the conditions of impregnation being such that the fabric contains 15-40% of vinyl pyridine rubber based on the total weight of the fibres and vinyl pyridine rubber. Unvulcanized rubber sheets may be calendered on to either or both sides of the impregnated fabric under conditions such as to cause the resorcinol-formaldehyde resin to condense completely and the rubber to vulcanize. Chafer strips may be cut from the fabric before or after calendering the unvulcanized rubber sheets on to it.

Abstract: 958,072. Endless conveyers. EASTWOODS Ltd., and J. PAISLEY. Oct. 31, 1962 [Oct. 31, 1961], No. 38965/61. Heading B8A. In transferring raw bricks from a conveyer 10 to a stepby-step moving marshalling platform 11, the conveyer 10 operating periodically in time with the platform 11 so as to deposit successive rows 48 of bricks on the platform 11, the leading brick on the conveyer 10 is separated from the last brick of the last deposited row 48, by the action of clamping members 44. The faces of the latter are inclined at a small angle to the axis of the conveyer 10 so that as the members 44 engage the brick it is thus given a slight twisting movement which causes it to break cleanly away from the last brick of the row 48. The members 44 are carried respectively by a fixed member 17 and a member 18 carried by slides 39 (Fig. 1) and displaceable by a ram of an hydraulic motor 19. The latter is energized in synchronism with an hydraulically operated clutch 14 (Fig. 7) which controls the drive of the conveyer 10. This mechanism is controlled by a valve V5 which is actuated by a solenoid " X " energized by the action of any one of limit switches LS1-LS4 according to a predetermined number of bricks fed on to the platform 11. The latter is moved step-bystep as described in Specification 849,805 by an indexing wheel 50 engaged by a pawl 52 displaced by a fluid motor 54. The valve V5 is reset by the action of the index arm 53. In Fig. 3, the axis of the motor 19 is normal to the axis of the conveyer 10. In a modification (Figs. 5, 6, not shown), the axis of the motor 19 is normal to the faces of the clamping members 44.

Abstract: 823,491. Batteries of steam boilers. HUET, A. Dec. 16, 1957 [Dec. 17, 1956], No. 39086/57. Class 123(2) In a battery of steam generators each consisting of a column a containing the tubulous heat exchange sections of the generator and heated by the downward flow therethrough of hot gas, for example the coolant .gas from a nuclear reactor, the columns are arranged in rows transversely of and below the main header b supplying the heating gas. Headers, c extending outwardly from the main header convey the gas to the top of each column via tubes k, the columns being arranged in double rows. Each double row of columns discharges coooled gas into a common header m which conveys it into the main discharge header n for return to the heating source, e.g. the nuclear reactor. Each double row of columns is supported by a girder d passing between the rows and supported at its ends on rollers h carried on walls f, g, the girder also supporting the main supply header b to which it is welded. The columns have projecting brackets j which rest on lugs i projecting from the girder, the arrangement being such that an individual column can be easily removed and replaced without interfering with the operation of the battery by disconnecting it and moving it into the space between the double rows whence it may be lifted clear. Moreover, the rollers h allow for lateral expansion movements of the battery, the discharge main being mounted resiliently at o to allow for vertical movement.

Abstract: 1,047,784. Removing leg tendons from carcasses. MAYWICK APPLIANCES Ltd. Oct. 22, 1963 [Oct. 22, 1962], No. 39975/62. Heading A2U. Apparatus for removing leg tendons from carcasses of animals or birds, particularly turkeys comprises a plate 2 having slots 1, into each of which a leg is inserted by an operator holding the carcase. The feet project above the plate 2 and they, or adjacent parts of the legs, are gripped by members 3, mounted on a platform 6, secured to the upper end of the piston rod of a pistoncylinder assembly (not shown) mounted in a supporting cabinet 4 and actuated by hydraulic pressure or compressed air, controlled by a treadle 5. The platform 6 is slidingly and non-rotaably mounted on a column 7 projecting from the plate 2. The operator actuates the treadle and causes the platform 6 to move upwards, the gripping members 3 to move first outwardly to break the legs and then upwardly to draw out then tendons. When a button 8 strikes a stop 9, the pressure medium is switched from the aforementioned pistoncylinder assembly to cylinders 10, mounted just above the platform 6, and causes pistons in these cylinders to push ejecting members 11 outwardly to remove the legs from the gripping members and the slots.
