Title: Improvements in or relating to sheet delivery mechanism for printing machines
IPC: B65H29/36
Filed: 1934-12-29
Abstract: 449,553. Sheet-delivery apparatus. LINOTYPE & MACHINERY, Ltd., 9, Kingsway, and STERN, C. L., 13, Manville Road, Balham, both in London. Dec. 29, 1934, No. 37233. [Class 100 (i)] A sheet-delivery apparatus for a printing-machine 2 comprises main delivery-tapes 1, a reciprocating tape-carriage 4 adapted to accommodate a number of sheets and to advance the sheets in successive stages to a position above the delivery-board 8, and means on the carriage for holding the sheets on the tapes during the movements of the sheets towards the delivery-board. The tapes 3 pass around rollers 9, 10 on the carriage and rollers 11, 12 mounted on the framing, so that in their extended condition the tapes can accommodate three sheets. A freewheel-device on the shaft of the roller 12 causes the sheets to be moved outwardly towards the board 8 during the outward movement of the carriage and to remain stationary during the inward movement in the usual manner, the carriage travel being such that each sheet moves one third of the distance towards the board for each reciprocation. Mounted on the carriage 4 are three sets a, b, c of stop-fingers 13 and grippers 14 adapted to engage successively the front edge of each sheet during the outward movements and to be raised above the sheets during the inward movement. Each set of sheet-engaging members 13, 14 is mounted on a shaft 15, Fig. 3, having roller-carrying levers 18, 20 engaged respectively by fixed cams 21 to lower the members at the inner end of their travel and by pivoted cams 22 to raise the members at the outer end of their travel. The movements of the carriage 4 are timed so that the carriage has started its outward movement and the sheet-engaging members a are lowered before the front edge of the sheet on the main tapes 1 reaches the carriage, the tapes 1 having a greater speed than the carriage so that they move the front edge of the sheet beneath the gripper-jaws 14, up to the stop-fingers 13. In order to prevent over-running of the tapes, the roller 11 is braked by two spring-pressed jaws 26 engaging the end thereof. Specification 397,227 is referred to.

Title: Optical sound-recording apparatus
IPC: G11B7/00
Filed: 1964-09-11
Abstract: 1,062,490. Optical sound recording apparatus. KALART CO. Inc. Sept. 11, 1964 [Dec. 11, 1963], No. 37362/64. Heading G5R. Sound is recorded optically as density modulation on parallel oblique tracks 27, Fig. 1, in areas disposed between picture areas 35 of a black and white or colour film. In Fig. 3 light from a ribbon filament lamp SL is reflected by mirrors M through lenses CL and masks 28 to mirrors Ma and lenses PL and to a prism P which merges the two beams and reflects them through a modulating mask MM and lens CL to the vibrating oscillating mirror 72 of a sound modulating galvanometer MG. Shutters 55 and 56 alternately open and close the paths of the two beams and are shaped to taper the ends of the tracks 27. The beam reflected by the galvanometer is reflected by a prism Pa to a recording lens RL and a beam splitting prism BS which directs one image to a film area N 1  and a second image to a film area N 2 ; a central part of the beam may pass axially through prism BS to a monitoring photo-cell (not shown). In operation, a film is mounted on a drum (not shown) rotating about the axis of the recording lens RL and the lens moves axially so that the beam traces helical paths on the film. A shutter 74 may be placed in the path of the beam when not recording to prevent fogging the film. Figs. 11 and 16 show the general arrangement of the apparatus. The recording assembly RA is mounted at the top of a tube 95 which is provided with a cut-out portion 101 extending 195 degrees round the tube. Film spools are arranged in the dotted area 145-162 of Fig. 11 on a rotatable deck plate 103 within a detachable cover 140 and the film path passes round the cut-out portion 101. In operation the plate 103 is rotated by a motor 105, thereby rotating a portion of film round the tube 95, and a threaded sleeve 100, Fig. 16, rotating with the plate drives a pawl 110 axially thereby causing axial displacement of the tube 95. When recording on a particular film portion is completed the pawl 110 is released by a solenoid (not shown) to allow the tube 95 to return to its initial position, and a solenoid 231, Fig. 11, is energized to interrupt the light path. Both these solenoids may be operated by a limit switch 118 actuated when the tube 95 reaches the end of its travel. To move the film on to its next recording location solenoids 185 (of which one is shown in Fig. 16) are energized to apply brake arms 187 to a gear ring 165 and to lower a sleeve 175, thereby withdrawing a locking pin 169 from a bore 168 in a gear 160. This releases a gear train to allow the film to be driven by a sprocket (not shown) to its next location when the pin 169 re-engages the bore 168 in gear 160. Solenoids 185 may be operated by a manual switch or in response to limit switch 118.

Title: Improvements relating to the catalytic reforming of hydrocarbons
IPC: C10G59/02
Filed: 1956-12-07
Abstract: A catalyst comprises supported chromium oxide and a minor proportion of a germanium compound.  The preferred support is alumina and the preferred germanium compound is the oxide.  The catalyst may be prepared by coprecipitation or impregnation and the preferred proportions (by weight of the material stable at 1020 DEG  F.) are 5 to 25% of chromium oxide, 0.1 to 5% of germanium oxide and the balance alumina.  The catalyst may also contain minor proportions of other promoters, e.g. an alkali metal compound such as potassium oxide, or ceric oxide.  In an example germanium dioxide is suspended in aluminium nitrate solution, ammonia is added and the resulting precipitate is dried, roasted, impregnated with chromium trioxide solution, and again dried and roasted.  The catalyst may be used for the dehydrogenation or dehydrocyclization of non-aromatic hydrocarbons (see Group IV (b)).ALSO:Feedstocks consisting of or comprising nonaromatic hydrocarbons are dehydrogenated or dehydrocyclized in the presence of a catalyst (see Group III) comprising chromium oxide and a germanium compound on a support and optionally other promoters such as potassium oxide.  The catalyst may be used as a fixed, moving or fluidized bed.  Preferred operating conditions are not more than 50 p.s.i.g. (including sub-atmospheric pressures); 450 DEG  to 850 DEG  C., particularly to 525 DEG  C.; 0.1 to 1.0 v/v/Hr; and no addition or recycle of hydrogen.  Feedstocks mentioned are pure hydrocarbons, e.g. stright-chain paraffins or cycloparaffins; mixtures of hydrocarbons, e.g. gasoline or naphtha fractions, especially a C5 to C7 fraction; and platinum reformates which may first be fractionated or solvent extracted. In examples: (i) a light fraction of a naphtha hydroformate (where the catalyst was halided platinum on alumina) having a F.B.P. of 108 DEG  C. was reformed with a catalyst consisting of 10% Cr2O3, 1% GeO2, and alumina (balance), at atmospheric pressure, 0.2 v/v/Hr, and 475 DEG or 530 DEG  C. for five hours, using no recycle gas; (ii) a 42.5 DEG to 112 DEG  C. straight-run gasoline is similarly reformed at temperatures of 475, DEG  500 DEG , 525 DEG  and 550 DEG  C., the other conditions being the same as in (i).

Abstract: 999,272. Echo sounding. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Oct. 25, 1961, No. 38207/61. Heading H4D. In an acoustic ranging and direction finding arrangement employing two pairs (or two pairs of groups) of transducers mounted in a common plane and having respective spacings b z , by (Fig. 1) in the ratio 2: 1 the signals from each pair being separately amplified, phase-shifted by 90 degrees, operated on to produce sum and difference signals and, after detection, applied in opposition to deflect a cathode-ray beam, the signals from the transducers spaced by the distance by producing the vertical deflection (voltage Uy) and those from the b x  spaced transducers producing the horizontal deflection (voltage U x ), the plane containing the transducers is rotated (about the vertical axis) until the horizontal deflection becomes zero (V x  = 0), i.e. until the phase difference between the signals received by the b x  spaced transducers is + r and the direction of the sound source (echo signal) is then given by # s  = Œ arc sin #/4b y , where is the wavelength of the acoustic energy employed and # s  is the angle between the direction of incident energy and the normal to the plane containing the transducers. This arrangement results in an improved signal-tonoise ratio over known arrangements utilizing sum-and-difference methods since, as shown in Fig. 2, the variation of the voltages U x , Uy with angle of incidence # of the received acoustic energy (0 being the acoustic axis) is such that only when # = Œ 30 degrees (termed the " squint " angle) is Uy a maximum and U x  equal to zero and extraneous noise sources, assumed to be statistically and uniformly distributed (with respect to the acoustic axis = 0) over the range - 90 to + 90 degrees, then have a resultant value of zero. In operation the plane containing the transducers is rotated until a central (radial) vertical trace is produced on the display tube (Uy=Max and Ux=0) and for optimum results the transducers should have maximum sensitivity in the direction of the angle of " squint " and a response which is symmetrical with respect to the acoustic axis (# = 0) to enhance the cancellation of extraneous noise. A preferred arrangement having the latter requirements is shown in Fig. 3 and comprises a total of five transducers 1 to 5 spaced apart by #/2, the voltage outputs E t  to E 5  of which are grouped (subtractively) in pairs, as shown, to provide input signals for the X and Y channels and the grouping being such as to provide the required spacing b, x  by. For range measurement known echo time arrangements may be employed and where the transducers 1 to 5 (Fig. 3) are also utilized for transmission the directional characteristic during transmission may be made to coincide with that during reception by energizing transducers 2 and 4 in opposite phase during transmission.
