Title: Improvements in or relating to bumpers or buffer bars for automobile vehicles
IPC: B60R19/18
Filed: 1929-06-25
Abstract: 314,388. Lacrotte, N. June 26, 1928, [Convention date]. Collision - guards. - A bumper or shock-absorber for motor vehicles comprises a transverse metal bar preferably of channel shape between the walls f of which are disposed a number of buffering elements a each provided with a cavity c, which may either be open at the rear or wholly enclosed, the forward portions of the elements projecting beyond the walls f of the transverse bar. The bar and buffering elements are then covered by a strip of canvas or like material g and finally by an outer rubber envelope h, the edges of which are connected together at the rear of the bar f, and held in place by T-shaped bars i adopted to support the bumper on the vehicle. In shape the buffering elements may be of trapezoidal section both tranversely and longitudinally as shown in Figs. 2 and 3, or they may be formed from tubular elements j, Fig. 6, closed by flat-ended caps k, or from moulded members j<1>, Fig. 7, each open at one end to receive a projection k<1> at the opposite end of an adjacent member. When the buffering elements are of cylindrical form, the bar f is preferably of semi-circular cross-section. The support for connecting each T-shaped bar i to the vehicle frame m comprises two telescopic tubes n, q enclosing hollow rubber buffers o, o<1>.

Title: Video time base corrector
IPC: H04N9/896
Filed: 1976-05-12
Abstract: 1521213 Television SONY CORP 12 May 1976 [15 May 1975 19 May 1975] 19556/76 Heading H4F A time base corrector which converts incoming periodic information signals, particularly colour video signals, to digital form and writes the digitized signals in a memory at a clocking rate which is modulated in accordance with the time base errors in the incoming signals, the digitized signals temporarily stored in the memory being read out therefrom during a reading period substantially at a standard clocking rate at least at the beginning and end of the reading period and reconverted to analogue form, is characterized by said memory consisting of a plurality of cyclically enabled memory units each having a capacity to store digitized signals representing an even number of said periodic intervals of the information signals. In the case of incoming colour video signals, the periodic intervals are horizontal line intervals of said colour video signals. The corrector thus allows easy compensation for signal drop-outs in video signals of the NTSC system wherein the phase of the chrominance sub-carrier reverses in successive line intervals. Reproduced composite colour video signals applied to an input 11 are passed to an analogue-to-digital converter 16. A separator 19, gated by horizontal synchronizing signals from a sync. separator 18, separates burst signals from the NTSC signals. The separated line sync. pulses and burst signals are applied to a write clock generator 20 which supplies write clock pulses to a system control circuit 23 which controls the operations of a memory control circuit 24 for effecting the writing operations of memory units MU-1 to MU-4 into which the digitalized signals are successively written. After momentary storage, the digitalized signals are read out in a predetermined sequence by means of a standard sync. generator 26 which supplies a signal at a standard frequency, e.g. the chrominance subcarrier frequency, to a read clock generator 27. The generator 27 produces read clock pulses at a standard frequency at least at the beginning and end of each reading period. During said reading periods, however, the read clock pulses may be modulated to eliminate or compensate for velocity errors in the input video signal. The memory units MU-1 to MU-4 are each provided with respective recycle loops 35 1  to 35 4  so that the information read out from a memory unit is simultaneously applied through the respective recycle loop to be rewritten in said memory unit. A dropout detector 36 connected to terminal 11 detects any dropouts in the incoming signals and provides a dropout signal to control circuit 23 and dropout memory 37. On detection of a dropout, the readout from one of the memory units. representing the same even number. particularly two, of line intervals which are free of dropout, is repeated. The memory units MU- to MU-4 each consist of eight shift registers.

Title: Improvements in or relating to a process for the production of caustic alkali solutions from alkali metal amalgams and to apparatus therefor
Inventor: GLOVER SIDNEY THOMAS
IPC: C25B1/42
Filed: 1959-06-10
Abstract: A process for the continuous production of caustic alkali solution comprises introducing alkali metal amalgam and water or dilute aqueous caustic alkali solution into a column to form therein a dispersion of aqueous phase in the amalgam, separating caustic alkali solution from partially denuded amalgam at the top of the column, passing the partially denuded amalgam from the top of the column into an annulus surrounding the column, introducing water or <PICT:0887670/III/1> dilute aqueous caustic alkali solution into the annulus to form therein a dispersion of amalgam in aqueous phase, removing caustic alkali solution from the top of the annulus and removing mercury from the base of the annulus.  The caustic alkali solution removed from the top of the annulus may be mixed with that from the top of the column.  In one embodiment, alkali metal amalgam is fed via a pipe 6 to the base of a column 5 packed with graphite rings. Water from a distributer 19 and the amalgam pass upwards in column 5 together with hydrogen generated in the resulting decomposition of the amalgam.  The partially denuded amalgam flows through holes 13 into an annulus 9, packed with lumps of graphite, to form a dispersion of amalgam in water introduced into the annulus 9 by a pipe 22.  At a level 27, caustic alkali solution formed in the annulus 9 overflows into caustic alkali solution 26 formed in the column 5 and separating above the partially denuded amalgam at the top of column 5.  The mixed solutions are withdrawn through a pipe 12.  Mercury is removed by a pipe 23 and hydrogen by a pipe 24. Specification 846,603 is referred to.

Title: Improvements in and relating to the manufacture of biaxially stretched tubular films
IPC: B29C48/90
Filed: 1961-06-01
Abstract: 977,473. Biaxially stretched tubular films. KALLE A.G. June 1, 1961 [June 1, 1960], No. 19862/61. Heading B5B. Biaxially stretched tubular organic thermoplastic film is continuously produced by extruding the heated film-forming material through the annular extrusion orifice of a die 2 (Fig. 1) to form a tube 1 which is solidified by drawing it over and in contact with an internally cooled metal mandrel 3 having a diameter greater than that of the extrusion orifice by means of endless conveyer belt tube advancing device 7. The tube is then drawn through a cylindrical passageway in a device 4 by means of which the temperature of the tube is raised to a stretching temperature below the crystallite melting point of the tube material while externally confined by the passageway and at the same time subjected to internal gas pressure by gas at a pressure slightly above atmospheric introduced into the tube by the pipe 8. The tube is withdrawn from the device 4 and longitudinally stretched by a pair of nip rollers 6 and simultaneously inflated and thereby transversely stretched during its unconfined travel from the heating device 4 to the two converging rows of rotatable rollers to form a tubular film 5. If the pressure with which the tube bears against the mandrel 3 is not sufficient to prevent pressurized air from flowing between the tube and the mandrel towards the extrusion orifice, an internal resilient cylindrical sealing element which is coaxial with the mandrel and fitted to an extension of the front of the mandrel may be provided. The process of the invention permits of the conversion of tubes of relatively high wall thickness into tubular films by biaxial stretching at high stretch ratios when the thermoplastic film material is of such a nature as to require the employment of high biaxial stretching ratios, e.g. low-pressure polyethylene and polypropylene.
