F should exist on a raw data line assuming no time shifting due to transmission difficulties (as shown, pulses A, D and F occur at the proper times a,f and i, whilst pulses B, E are early and pulse C is late) comprises a voltage controlled oscillator; means producing a first signal X 7  for increasing the frequency of the oscillator, which signal is initiated at the leading edge of a raw data pulse and is terminated a predetermined time after a data time such as a, b, &c. (as shown, the predetermined time is one quarter of the normal time interval between successive pulses); and means producing a second signal X 6  for decreasing the frequency of the oscillator, the second signal being initiated when the signal X 7  terminates and being terminated midway between the data times such as a, b &c. Suitable circuitry for producing the clock pulses is described with reference to Figs. 1 and 2 (not shown), and includes a charge pump which controls the oscillator in response to the signals X 6  and X 7  which are derived from NAND gates. The specification shows how this arrangement provides clock pulses from input data signals which do not include regular clock pulses and which may be, for example, signals of modified frequency modulation which only includes clock signals, such as G in Fig. 3, between two consecutive zeroes of the data signal.
Patent GB-229438-A (GB)
Abstract: 229,438. Strachan & Henshaw, Ltd., Sargent, T., and Knight, E. J. Dec. 22, 1923. Rotary tipplers.-The rail platform of the tippler moves during tipping to bring the upper edge of the wagon against supporting surfaces on the tippler so that the wagon is locked automatically on the tippler under the action of its weight, without the use of any independently operated clamping devices such as bars or chains. The wagon may remain approximately stationary during one or more stages of the movement of the tippler, whilst relative movement takes place bringing suitable abutments into contact with the sides and top of the wagon. The rail platform in the tippler may be free to follow the movements of the wagon, so that there is no tendency for the wagon to leave the rails, and the platform can move relatively to the wagon body when the springs of the wagon are relieved of the load. The tippler rings may run on pairs of rollers carried by balancing beams for evenly distributing the load. As shown in Fig. 1, an L-shaped cradle 1 is connected with the tippler rings 2 by parallel links 6 pivoted at 7 and normally rests against stops 9. The rail platform 4 is suspended from the cradle 1 by parallel links 4<1>. Buffers 3, 8 are mounted on the cradle and tippler rings respectively to engage the side and top of the wagon. The tippler rings rest on pairs of rollers 12 mounted on balancing beams 10. When the tippler is rotated in the counterclockwise direction, the buffers 3 are brought against the side of the wagon, and the wagon and cradle then move with the tippler rings until the cradle swings under gravity to bring the top of the wagon against the buffer 8, after which the truck, cradle and tippler move as one. The cradle 1 may be constructed with end members, and may be guided by rollers or slides instead of the links 6. The buffers may be mounted on balanced bars, studs, slides, rollers or springs, and the top buffers 8 may exert a tendency to keep the wagon against the side buffers 3. The rail platform 4 may be suspended by chains instead of links, or it may be mounted on rollers, skids, or slides. In a modification, Fig. 2, the side support 5 is mounted on a jointed frame 7 - - 9, 7' - - 9<1> pivoted to the tipper at a<1> - - a' and comprising geared sectors as shown, so that during tipping the weight is supported by the frame 7, 7<1> &c., and the wagon together with the members 7, 7<1>, moves in the direction of the arrow until supported by the buffers 6.

Filed: 1956-07-25
Abstract: 836,019. Magnetic amplifiers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. July 25, 1956 [July 28, 1955], No. 22987/56. Class 40 (9). [Also in Group XXXV] A transformer tapchanging arrangement includes pairs of autoself-excited bridge rectifying transductors 2 and 3, 19 and 20, 21 and 22, operating in pushpull (see Group XXXV) and connected in cascade. The transductor 2 includes control windings 2c, 2b, which act in opposition to each other, and a winding 2a which carries a constant current and renders the transductor insensitive over a predetermined range. Transductors 19 and 20 introduce a delay in operation, the transductor 19 having a bias winding 19a which adjusts the working point of the transductor so that when transductor 2 is not supplying any control current to winding 19c, transductor 19 is fully conductive and holds the impedance of transductor 21, via control winding 21a, at a high'value so that no control current is applied to the load 7. The blocking of transductor 19 on energization of winding 19c is delayed by short-circuited winding 19b, the delay being adjusted by resistor 23. The transductor 21 is given a bi-stable characteristic by means of feed-back winding 21b.

Title: Knitting machine needles and means for operating same
IPC: D04B23/00
Filed: 1944-11-20
Abstract: 601,020. Knitting. DEHN, F. B. (Vanity Fair Mills, Inc.). Nov. 20, 1944, No. 23069. [Class 74 (ii) ] A tongue member, the shank 24 of which lies adjacent to the shank of a knitting- machine needle whilst the thread passage of the needle hook 20 is open, is, at the appropriate times, swung out of the groove about its upper end (which is anchored within the compass of the needle hook) to close the passage. The tongue may be in a groove in the needle shank, and that part lying within the compass of the needle hook may be flexible and anchored at 27 by welding or the like, or rigid and pivoted at 44. To provide the necessary relative movement between needle and tongue, the needles are carried on a needle bar 11 pivotally mounted on vertical shaft 3 which can reciprocate on bearing 2, and each tongue is supported by an arm 28 resting in a slot in an arm 15. As the shafts 3 are reciprocated vertically by an eccentric 7, the needle bar is rocked about its pivot 13 by suitably shaped cams 30, 31 acting through rocker arms 33, 14 and connecting rod 36. When, in place of the swinging and rocking thread guides 43 of a tricot machine, stationary thread guides are employed, the cams will, in addition, be shaped to tilt the needles to the proper degree and at the proper times to pick up the thread before closing the thread passage. The needles may be pointed when used on machines which knit through a base cloth.

Title: Improvements in fire-extinguishing apparatus
Inventor: HENSHAW THOMAS ANTHONY
IPC: A62C13/00
Filed: 1955-08-10
Abstract: 807,920. Closures for resisting fluid pressure. PYRENE CO. Ltd. Aug. 10, 1956 [Aug. 10, 1955], No. 23072/55. Class 123(1) [Also in Groups XVII and XXI] In a fire-extinguishing apparatus, the 'fire-extinguishing medium container has a necked opening with a cylindrical surface and a closure member with a complementary cylindrical surface, in which both surfaces have threads so that the closure member can be screwed into position, and in which a seal is made between both surfaces when a packing housed in a groove in one of the surfaces makes contact with an unthreaded part of the other surface. In Fig. 1 a neck 3 brazed into a fire extinguishing liquid container 1 is coarsely threaded internally at 7 and is provided with a smaller diameter part 6 having a cylindrical surface against which bears an O-ring 11 to seal the opening, the O-ring being carried in an annular groove 10 of rectangular cross-section provided in a plug 4 which engages the neck 3 by means of an external threaded part 9 corresponding to the threaded part 7. The length of the threaded parts 7 and 9 is such that, when the member 4 is being unscrewed the O-ring moves clear of the surface 6 so as to break the seal before the threaded parts disengage, the pressure then being vented through a hole 16 to prevent the member 4 from being blown away from the container. In a modification for a container for fire extinguishing powder, Fig. 2 (not shown), the screw plug 4 is replaced by a screw cap engageable over an externally threaded part of the neck, and the O-ring is contained in an external groove around the neck, the base of the groove being inclined so that in response to pressure in the container acting on the O-ring, the base of the groove exerts a radially outward reaction upon the O-ring to increase the sealing effect. Specification 807,919 [Group XXI] is referred to.
