Title: Apparatus for the continuous,intermittent irrigation of a vessel or bladder with elastic or inelastic but flexible walls
IPC: A61M3/02
Filed: 1962-02-22
Abstract: 967,346. Lavage apparatus. A. W. MITCHELL, and C. M. CRAYTHORNE. Feb. 21, 1963 [Feb. 22, 1962], No. 6836/62. Heading A5R. An appliance for lavage of the bladder comprises an automatic syphon device which repeatedly fills and empties the bladder. Water is received, at a predetermined slow rate, into the upper end of a tube A, the lower end of which is connected, through a flexible tube, to the patient. As the bladder fills water also flows up a lateral branch to an inverted U-tube C and so into the interior of a cylindrical container. When this is completely filled, water then flows over the upper bond of a second U-tube B and syphons over into a suitable receptacle. This results in emptying of the bladder and when the flow is reduced, towards the end of this operation, air entering through a restricted inlet in the top of the tube B, is sufficient to interrupt the syphon with the result that the bladder is again filled.

Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1927-03-17
Abstract: 292,247. Fitzpatrick, H. D., (U.S. Slicing Machine Co.). March 17, 1927. Cutting slices in succession. - In a slicing-machine, the slice receiver comprises a stationary plate and a movable slice support which is inclined with its upper side spaced more from the knife than its lower side and also with the end of the support, towards which the slices move, spaced more from the knife than the opposite end. As shown in Figs. 3, 4, and 6, the invention is applied to a disc knife reciprocating carrier machine, the knife 14 being driven by a motor 20 through pulleys 15, 18 and a belt 17. The carrier 43 is of trough form, having walls 44, 45 which are ribbed to minimize friction as the substance is fed by hand towards and against a feed abutment plate 29. The knife-driving means are enclosed in a casing 16, 21, 22, the portion 21 being extended and shaped to lie in the recess 23 in the face of the knife 14. The opposite side of the is substantially enclosed by the slice deflector 51 which is horizontally ribbed to minimize friction as the slice moves along it. The carrier 43 is guided on a rod 46 and rotation about the rod is prevented by the engagement of a depending portion 49 of the carrier with another guide 48. The carrier is reciprocated by hand, a handle 50 being provided. The feed abutment plate 29 is carried on parallel motion links 33, 36 and adjustment is effected by a band wheel 29 on a shaft 40 having a worm connection with the shaft 31 carrying the links 33. The slice receiver comprises a downwardly inclined stationary plate 54 having an abutment wall 55 towards which the slices are projected. The plate 54, 55 is ribbed to minimize friction and is slotted at 58 to permit the downward motion of a support 56 carried by a bracket 57 operatively engaging with an intermittently rotating screw 59. The support 56 is substantially normal to the surface of the plate 54 so that its upper side is spaced further from the knife than its lower side. The end adjacent to the wall 55 is, moreover, spaced further from the knife than the opposite end, as shown in Fig. 3. The inclination of the plate 56 may be substantially the same as that of the slice deflector which may itself be of overhanging form. The support 56 is moved intermittently downwards to accommodate the slices as they are deposited by the motion of the screw 59 which is provided with a ratchet wheel 62 engaged by a pawl on a lever 64. The lever 64 is normally kept against a stop pin 65 by a torsion spring 67, Fig. 6, and oscillation of the pawl lever 64 is effected by a projection 69 on the carrier 43. The bracket 57 is connected by a spring-pressed ball 70 to the screw 59, so that, to adjust the support 56, it is only necessary to exert sufficient force to cause the ball 70 to ride over the threads of the screw 59.

Title: Improvements in and relating to magnetic extractor devices
IPC: G06K13/08
Filed: 1960-03-04
Abstract: 876,339. Selecting records for sensing. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 4, 1960 [March 9, 1959], No. 7688/60. Class 106 (1). [Also in Group XX] One of a number of record strips in a bin 12, Fig. 1, is selected for reading or recording by a magnetic picker having a polepiece at one end for co-operation with a metal tab on the selected record, adjacent records being prevented from being withdrawn by restraining elements on either side of the polepiece. The bin 12 is covered by a movable carriage 17 carrying the lower ends of flexible guides up which the selected record is drawn to a recording or sensing station 13. The picker is carried on a bracket 29 fastened to a metal band 27 which passes over pulleys 28 and 31 and which is displaced by driving means to position the desired frame of the record at the recording to sensing station 13. The picker device, Fig. 3, consists of a magnet 35 having the active polepiece 36 at the lower end shaped to project through an opening 38 between the two frame members 37, the lower portions of which form the restraining elements preventing other records from being lifted. The bracket 29 is attached to the magnet 35 through a metal strip 33 and the frames 37 are movable relative to the magnet by compression of spring 44. To select a record the drive band 27 is moved to bring the picker down against the top of the bin compressing the spring as shown in Fig. 5 and projecting the polepiece against the desired record 11. The picker is then lifted, carrying the record with it until the desired frame is aligned with the station 13. In another form the side frames are pivoted and act as jaws to grip the top of the record as it is lifted. In the lowermost position the jaws are opened to allow the polepiece to pick up the desired record and as the picker rises the jaws close by spring action to grip the record. There may be a large number of bins 12, the desired bin being selected by relative movements between them and the picker.

Abstract: 810,405. Hydraulic turbines. ETABLISSEMENTS NEYRPIC. March 8, 1957, No. 7834/57. Class 110 (3). [Also in Group XXIX] A tidal power plant comprising an axial flow hydraulic turbine located in a conduit connecting two liquid masses separated by a dam and operable in two directions of flow has a diffuser located on at least one side of the turbine and formed in continuation of the conduit to terminate in an aperture formed in one of the wall faces of the dam and guide means associated with the aperture to impart rotary motion to the water entering the aperture but to interfere as little as possible with the flow leaving the aperture. A diffuser 13, Fig. 1, leads to an axial flow turbine. When the water is leaving the diffuser, Fig. 1, the flow separates from the edges of the aperture 10 and forms a stream of liquid 15 which disperses in a body of water 12. When the water enters the diffuser, Fig. 2, some of the individual streams of water 16 pass through the guide vanes 17 so that the flow of water is given a rotary motion in the same direction as that of the turbine rotor. In a modification, Fig. 3 (not shown), the guide vanes are mounted on a flared portion at the end of the diffuser remote from the turbine. The turbine may have in addition the normal movable guide vanes on both sides or may have the normal movable guide vanes on one side and the arrangement according to the invention on the other.

Title: Improvements in or relating to data recording
Inventor: STREETER JOHN HAROLD
IPC: G11B5/265
Filed: 1968-02-16
Abstract: 1,263,471. Digital information recording system. PLESSEY CO. Ltd. 7 Feb., 1969 [16 Feb., 1968], No. 7836/68. Heading G5R. In a digital information incremental recording arrangement the information recorded in each tape channel is immediately checked by playback and comparison with the information required to be recorded in that channel. Each recording head 2 and playback head 3 form a single unit and the reluctance of the playback head is increased by a large non-magnetic gap 11 which reduces the direct pick-up of the recording signal in the playback head circuit. The information to be recorded is applied to a store 15 and controls a gate 16 feeding clock pulses from generator 17 to a bi-stable switch 18 which controls a write amplifier 19. These circuits include conventional apparatus for writing on tape using the NRZI system and the recording takes place when the tape is stationary. During forward movement of the tape to the next incremental position the recorded signal produces an output from the playback head which is amplified, 20, and then passed via a gate circuit 27 to a full wave rectifier and thence to a voltage level detector 22. The level detector output is passed via a second gate 23 to a bi-stable switch 24 and thence to a comparator 25 which compares the signal with that stored in unit 15. The output from the comparator is supplied via a gate 32 to indicate any error at output 26. The gates, which are energized by delayed clock pulses, serve to ensure that the direct record signal and other extraneous signals caused, e.g. by braking of the tape are excluded from the played-back signal and that the comparator is correctly sampled. A similar checking arrangement is provided for each tape channel. Incremental step length can be controlled by using the playedback signal to control the point at which the tape is stopped for the next bit to be written.
