Title: Still picture projector with device for enlargement of sections of the projected image
IPC: G02B1/00
Filed: 1958-10-01
Abstract: 888,961. Projectors. AGFA A.G. Oct. 1, 1958 [Oct. 18, 1957], No. 31355/58. Class 97(1). A projector having an objective 9 has a second objective 11 of shorter focus arranged for alternative passage therethrough of the light beam, with means for holding a transparency in the path in this alternative passage; this means can be moved in its own plane in two directions at right-angles, so that different sections of the transparency may be brought into the light beam for projection on to the same screen of an enlarged image of that particular portion. In the embodiment of Fig. 1, light from lamp 2 passes through condenser' lenses 4, 5, and out through an aperture 6 in the lamp house 1. Here is disposed a transparency in a slider 8. A normal objective 9 throws an image of the whole transparency on a screen. To produce a magnified image of any part of the transparency, the whole objective housing 10 is moved upwards so that the shorter focus lens 11 occupies the objective position. The transparency is transferred to a slider 13, which can be moved in two directions at right-angles, so that any portion can be brought within the light beam for magnified projection. Behind this slider is a masking frame 12, and the slider is so positioned relative to the front wall of the housing 10 that the whole of the light beam 7 passes through it and the objective 11. Thus the enlarged section, as projected, has the same brightness as the whole projected image. In the alternative form of Fig. 3, the two objectives 9 and 11 are both fixed, the light beam being deflected from one path to the other by means of mirrors 14, 16.

Abstract: 1480371 Continuous type towel dispenser STEINER CO LAUSANNE SA 16 July 1974 [4 Sept 1973] 31476/74 Heading B8M In a continous-type towel dispenser in which clean towelling passes upwardly between a shiftable pinch roller and a drive roller, over the pinch roller downwardly and out of the housing into a loop accessible to a user, and back into the housing to a shiftable and rotatable used towel storage roller contacting the drive roller, the three rollers are mounted on supports on either housing side, and the pinch roller and the drive roller are mounted by roller surfaces on the supports. As shown, Fig. 3, towelling pulled downwards into exposed loop 205 rotates tubular pinch roller 160 and presses it via running towel against tubular drive roller 140 which rotates expanding used-towel roll 207 on storage roller 130. The towel is urged into contact with roller 160 by door-mounted member 104. The roller surfaces lie on two supports 110, Fig. 4, each of one or more pieces. Roller 160, larger than roller 140, is mounted on support guides 125 with its e.g. above that of roller 140 which is mounted on support surfaces 120. Stub shafts 132 of roller 130 initially rest on support elbows 117 and rise and rotate on support ramps 116. The pinch and drive rollers have an abrasive covering, e.g. sandpaper. One pinch roller end, Fig. 8, having bent-out cam 168 and stop 172 coacts with pivoted pawl 180 to form a towel dispensing stop. After less than 360 degrees of anti-clockwise rotation from a first position, Fig. 8, cam 168 coating with follower 190 projects pawl catch 195 to abut stop 172, Fig. 9. Release of the towel allows weighted end 199 to pivot the pawl to the Fig. 8 position. A straightener for used towel re-entering the dispenser through slot 80, Fig. 10, is formed by towel-contacting edges 71, 76 on plates 70, 75 which are spaced to allow an attendant's hand to feed a towel end on to roller 130. Alternatively, Fig. 11, pinch roller 360 drives storage roller 320 via chain-coupled drive rollers 340, 350, and roller 320 is guided in slots between ramps 316, 318.

Title: Magnetic recording of wide-band signals
IPC: H04N5/92
Filed: 1959-09-16
Abstract: 881,049. Magnetic recording. FERNSEH G.m.b.H. Sept. 16, 1959 [Sept. 16, 1958; Nov. 6, 1958; April 25, 1959], No. 31570/59. Class 40 (2). In an arrangement for recording video signals the recorded signal comprises a frequencymodulated signal based on a virtual carrier of the same order of magnitude as the lower limit of the recorded frequencies. Signal S, Fig. 7, after amplification controls a clamped resistance tube Vc to frequency-modulate an oscillator O, the vision component modulating a 45 Mc/s. carrier over the range 45-46 Mc/s. and the synchronizing signal over the range 44.5- 45 Mc/s. The F.M. signal is translated by a 61 Mc/s. oscillator O1 in mixer M1 and the output selected by a low-pass filter F, is translated again by a 19.5 Mc/s. oscillator 02 so that the stronger upper sideband is in the recording range and the virtual carrier is at 3.5 Mc/s. The recording and reproducing characteristics are arranged to be substantially horizontal over the frequency range #f traversed by the carrier. The reproduced signal S1, Fig. 8, passes through a phase splitter P to produce two signals of opposite polarity which are mixed in a push-pull mixer M3 with a 19.5 Mc/s. signal from oscillator 03. The lower modulation band, and the residual carrier are removed by a band-pass filter F1 (10-19.5 Mc/s.), and the signal is passed through a further phase-splitting amplifier with wide-band coupling circuits to provide a push-pull output, which is converted by a discriminator D to an amplitude-modulated television signal. The output circuit includes a phase-correcting low-pass filter F2 and a buffer amplifier A3. There may be included in the recorded signal an F.M. signal corresponding to a periodically recurring reference level whereby any deviation of the frequency from its intended value is counteracted or reduced.

Title: A process for producing a rod of low-resistance semi-conductor material
IPC: C30B13/10
Filed: 1960-09-13
Abstract: Pure silicon is deposited from a gas or vapour on to a rod of silicon containing phosphorus as doping agent to produce an enlarged rod of substantially known phosphorus content, whereafter the enlarged rod is subjected to zonemelting such a number of times and at such a speed of travel that a predetermined degree of evaporation and residual concentration of phosphorus is obtained.  Half the total number of passages of the molten zone may be in one direction and the other half in the opposite direction.  A seed crystal, which may be rotated, may be used to form a monocrystalline rod.  The phosphorus-containing rod may be produced by deposition on a silicon carrier rod of a mixture of silicon and phosphorus from hydrogen containing vaporized phosphorus trichloride and silicochloroform with subsequent zone-melting and simultaneous stretching.  An n-conducting rod having a resistivity of 100 ohm-cms may be produced from a polycrystalline rod having a resistivity of 10 ohm-cms by the passage of four molten zones at 3 mm per min, or five passages at 4 mm per min and a further one at 3,5 mm per min.

Title: Improvements relating to closing mechanism for an electric circuit breaker
IPC: H01H3/30
Filed: 1939-12-11
Abstract: 537,180. Automatic circuit-breakers; actuation of switches. BRITISH THOMSONHOUSTON CO. Ltd., and HUNTER, M. C. I. Dec. 11, 1939, No. 31952. [Class 38 (v)] A circuit-breaker closing mechanism of the type in which operation is effected by release of energy stored in a spring, employs flywheel means which absorbs part of the initial spring-energy and gives it up again when the breaker-parts are beginning to slow up due, for example, to shortcircuit forces. The flywheel means comprises a pair of co-axial flywheels one behind the other, pivoted on stub axles 5 and interconnected by a crankpin 4 which is coupled through a lever 7 to a lever 8 pivoted at 9. Lever 8 is linked at 10 to a cross head 11 between which and a fixed abutment 14 the spring 13 is compressed. The crosshead also carries a cylinder 15, the bottom closure 17 of which supports a loaded damping spring 18 bearing on a plunger 19 on which abuts the plunger 2 connected to the contacts (not shown) through trippable mechanism. To stress the spring 13a, a motor, Fig. 2 (not shown), is driven, or handle 28 continuously oscillates a lever 24 whereby a pawl 25 thereon engages ratchet teeth 20 on the front fly-wheel 3a to rotate it progressively clockwise from the position shown to a position where the pin 4 is just past the lower dead-centre whereat the parts are held by a releasable roller 22 engaging a notch 21 in the rear flywheel. At this point, indicated by a switch 36 operated by roller 22, the ratchet teeth come to an end and the roller 22 can be operated to release the stored energy either by a push rod 37 or by a solenoid 38. A retaining pawl 31 engages the teeth 20 to prevent backward rotation of the flywheels by spring 13 during the charging operation, when the crosshead 11 is being lowered. When tripped to close, the crosshead rises and pushes up the rod 2 and when the breaker is tripped, and with the spring 13 charged, the rod 2 falls under gravity assisted if desired, by a light spring, to reset the automatic trip mechanism. In a modification suitable for a smaller breaker, Figs. 3, 4 (not shown), the closing spring is arranged to lower the rod 2 to close the contacts. the rod 2 being raised again by a light spring and having a modified form of connection with the crosshead.
