Title: Improvements in or relating to photographic cameras
IPC: G03B13/06
Filed: 1932-08-12
Abstract: 389,379. Telemeter and view-finder for photegraphic cameras. LEITZ GES., E., Optical Works, Wetzlar, Germany. Aug. 12, 1932, No. 22577. Convention date, Oct. 17, 1931. [Classes 97 (i) and 98 (i).] In a combined telemeter and viewfinding attachment for cameras, the rays from the object which approach the eye respectively through the telemeter and the view finder are not coincident, but are brought so close together as to be incident on a single eye, so that a slight movement of the eye alone is sufficient to enable such rays to be viewed successively. As shown in Fig. 1, the rays from the transmitting reflector D of the short-base telemeter are reflected by a pair of right-angle prisms H, J so as to emerge from the casing A through a window K adjacent to the eyepiece G of the view-finding telescope F, G, which is housed in the casing between the telemeter mirrors B, D. In this construction, the two bundles of rays emerge parallel, but in a modification the prisms H, J are replaced by a single compound prism, which deflects the rays from the telemeter through the window K so that they cross the rays emerging from the finder F, G at the point where the eye is placed. Instead of deflecting the rays from the telemeter, the rays from the view finder may be deflected.

Title: Improvements relating to combined wireless and phonographic or like sound reproducing machines
IPC: G11B31/00
Filed: 1923-09-08
Abstract: 203,710. Marconi's Wireless Telegraph Co., (Assignees of Goldsmith, A. N.). Sept. 9, 1922, [Convention date]. Receiving sets, construction of; thermionic amplifiers and detectors; local disturbances, eliminating.-A wireless receiver is compactly mounted inside the cover or other movable part of an ordinary phonograph cabinet in such a way that when the lid is thrown back the tuning and other controls are convenient for manipulation. The disposition of the parts is shown in Fig. 5, whilst Fig. 9 is a wiring diagram of the receiving circuit. The primary inductance 46, coupling coil 48, and tuning condenser 52 are housed in a metallic shield 171, mounted on the sloping panel 40, a similar shield containing the secondary coil 50 and condenser 54. A metallic base plate constitutes a further screen and also serves as a common earthing point 164, Fig. 9, which is connected through the plugs 168, 170 with an outside earth GND. The five valves 84, 86 - - 92 are mounted on a plate 96 yieldingly supported by springs 100 from the panel. The switch 128, Figs. 8 and 9, controlling the aerial inductance, the switch 136 regulating the secondary inductance, and the double switch 110, 118 connecting the primaries and secondaries of a series of highfrequency transformers 116<A> - - 116D are all moved simultaneously from a single control knob 150, Fig. 8, through the link work shown. All the controls are numbered in the correct sequence of operations so as to facilitate manipulation by an unskilled person. The normal grid potential is fixed at -3 volts by means of a separate tapping from the battery as shown. A single amplifying horn serves to reproduce sounds coming either from a phonographic record or from the wireless receiver. For this purpose the horn 12 is branched into two parts 18, 20 as shown in Figs. 5 and 6. The branch 18 is fitted with a tone arm and sound box 26 adapted to rest upon the usual record turntable 32. The branch 20 is connected to a telephone 36, Fig. 9, and constitutes a loud speaker for the received wireless signals. A valve or flap 267, Fig. 6, which normally closes the branch 20, is automatically swung into the dotted-line position by an electromagnet 272, Figs. 5 and 9, when the filament-heating switch 266 is closed. A plug-in switch 254 allows the use of head phones in place of the loud speaker. Dry cells are preferably used for the filaments and the battery is formed with projections which slide into a trackway in the housing compartment so as automatically to make correct contact with the internal circuit.

Title: Improvements in and relating to slicing machines
IPC: B26D7/32
Filed: 1923-09-11
Abstract: 214,908. Fitzpatrick, H. D., (Maatschappij tot vervaardiging van Snijmachines volgens van Berkel's Patent en van Andere Werktuigen). Sept. 11, 1923. Cutting slices in succession.-A slicing-machine is provided with a slicereceiving table which is moved, step by step vertically downwards and horizontally, in synchronism with the slice-depositing mechanism, the slices being thereby stacked in an attractive manner. As described, the horizontal motion is an intermittent rotation. A pair of bars 10 project from the frame 11 of the machine and carry a cross-bar 12 having a vertical standard 13 on which travels a runner 14 secured to a frame 20 which carries the beaded-edged, circular table 30. A screwed shaft 16 is positioned parallel to the standard 13 and is moved intermittently by a ratchet wheel 17 operated by a bar 18 from a suitable part of the machine. The screwed shaft 16 is engaged by a spring-pressed, half-nut 21 which is disengaged by a rod 23 and handle 24. and a sprocket-wheel 26, slidable on the shaft 16 and journaled in the frame 20, is rotated with the shaft 16 by engagement of a key 28 with a keyway in the shaft. A bracket 29, on the frame 20, carries a journal for a sprocket 34, connected with the sprocket 26 by a chain 38, the sprocket 34 being frictionally connected to the table 30 by a screw 32. A spring 36 provides the friction drive between the sprocket 34 and the table 30 and the latter may be locked by a brake shoe, operated by a thumbscrew, without interfering with the vertical movement of the table. In Fig. 2, the table is in its lowest position and the half-nut is adjacent to the plain portion of the shaft 16. In this position the table revolves without vertical motion. An arm pivoted at one end to the machine base and at the other to the frame 20, adjacent to the handle 24, prevents rotation of the frame 20 about the standard 13. The table may be moved bodily in a straight or curved path during its rotation.

Title: Improvements in electric protective arrangements
IPC: H02H3/30
Filed: 1930-07-29
Abstract: 360,455. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, and LANE, F. J., 97, Harlesden Gardens, Harlesden, both*in London. July 29, 1930, No. 22830. [Class 38 (v).] Relates to a protective system for lines and apparatus in which a vibrating relay 5, 13 at each end of the section 1 is energized by a current transformer 2, 3 and the contacts of the two synchronous relays are interconnected through pilot wires 9, 11 and the tripping coils 10, 14 of the circuit-breakers so that when the vibrating relays fall out of synchronism on fault the circuit breakers are tripped. According to the invention, in order to adapt the system to a circuit fed from one end only, an auxiliary overload relay 18 is produced at each end energized from current transformers 4, 12 and serving normally to short-circuit at the contact 19, the operating windings of the vibrating relays, and at the contacts 20 the trip coils 10, 14 of the circuit breakers and also the contacts of the vibrating relays. In consequence, the vibrating relays do not come into action until a fault develops. In the event of default, with the supply as from one end only, the " far end " relay 18 may not be energized but in this case the contacts of the vibrating relay at this end remain short-circuited and the pilot wire circuit is intermittently closed by the " near-end " vibrating relay thereby causing tripping of the " near-end " circuit breaker. With through faults both relays 18 operate to leave the protection in charge of the two vibrating relays which will vibrate in step without result if the fault is outside the section. In a modification for a three-phase circuit, Fig. 3 (not shown), a pair of vibrating relays at each end is employed energized by current transformers connected to provide for earth faults as well as for faults between phases ; a single vibrating relay at each end is adequate to give full protection if connected up to current transformers which are interconnected as described in Specification 304,357, [Class 38 (v), Electric switches &c.]. In this case, the auxiliary overload relays are unnecessary as the vibrating relays are energized only on fault. The system may be extended to provide for the tripping out fault of the circuit breakers at both ends although the supply is from one end only, Fig. 6 (not shown).

Filed: 1975-05-23
Abstract: 1469588 Printers INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [28 June 1974] 22918/75 Heading G4H A printer includes a carrier movable past a plurality of print positions along a print line of a document, a rotatable print wheel mounted on the carrier and having an array of type characters around the periphery divided into two groups, a print hammer carried by the carrier operable to effect impact of a selected type character to print in print positions on the document, and means to cause the hammer to shift in relation to the document in accordance with the group from which the type character is to be printed so as to be in appropriate print column position. In one embodiment, the hammer is shifted relative to the carrier in the direction of the print line by a spring when a solenoid is de-energized. In another embodiment, the hammer is shifted by shifting the carrier carrying it by a half print position, two split nuts (spaced an odd half integral number of character positions apart) being able to be selectively coupled to a constantly-rotating lead screw to drive the carrier along the line (the first embodiment having only one split nut). One group of characters contains lower case and numerals, and the other contains upper case and special characters. There is no hammer recovery gap between groups on the print wheel, and if successive print positions require use of the second group followed by the first group, printing and carrier movement along the print line are inhibited to allow hammer recovery (which would otherwise normality occur during passage of the group not in use).
