Title: Arrangement for optical scanning of the speed of a rotating member
IPC: G01P3/486
Filed: 1974-02-05
Abstract: 1454811 Measuring rotation photoelectrically LBA SWIDEN and W LESTER 5 Feb 1974 [6 Feb 1973] 05320/74 Heading G1A In a rotational speed transducer of the type having a toothed or perforated wheel between a light source and a detector, the teeth or perforations are so shaped that by moving the source and detector radially along the teeth or perforations the ratio of the time for which the detector is illuminated to the time it is in shadow can be changed; as a result a position can be chosen where whatever the inherent switch-on and switch-off delays of the detector an electric pulsed output signal is provided in which the on time and the off time are equal. Fig. 2 shows a side view of a toothed disc 3 attached to a rotating shaft 2. Light source 5, photo transistor M and resistor 17 are connected to battery 15 to produce a pulsating voltage a 19 which is substantially a squarewave varying between zero and the battery voltage. The optical assembly can be moved radially by slackening bolts 24. As seen in Fig. 1 the gaps 6 between the teeth 5 are parallel sided, and the teeth are wider at the circumference than at the root. By moving the assembly outwards the ratio of time illuminated to time in shadow decreases. It can thus be arranged that although the photo transistor switch-on and switch-off times are not equal and vary from one device to another, the apparatus can be set up so that the ratio of the time the transistor is on to the time it is off is unity, Fig. 5 (not shown). The transistor output may be displayed on a CRT during this setting up. The apparatus is made of non- magnetic material to avoid inductive effects, and may be used for vehicle wheel anti-lock braking systems.

Title: Apparatus for collecting peat sods which have been spread out for drying in the air
IPC: E21C49/00
Filed: 1951-03-06
Abstract: 698,510. Endless conveyers and elevators. HESEPER TOREWERK GES. March 6, 1951. [March 8, 1950] No. 5361/51. Class 78 (i). A mobile apparatus for mechanically collecting peat sods laid out on a field for drying and adapted to be driven over the field, comprises a plurality of elevators provided with rake bars adapted to pick up the sods and feed them to a conveyer arranged transversely to the elevators and to the direction of travel of the apparatus and adapted to convey the sods to a collecting point, each of said elevators being coupled to the conveyer by a universal or other coupling whereby the elevators are capable of pivotal movement about the coupling in a vertical plane and also laterally relative to the conveyer. As shown, a number of elevators A, arranged side-by-side and comprising rake bars 7 mounted on a pair of endless chains B, feed the sods to a belt conveyer B supported by a plurality of trolleys 17 spaced along its length. Each elevator is mounted on the frame 4 of the conveyer B by a coupling 5 such as a universal joint, and is supported at its lower end by wheels 6. The chains 8 pass over sprockets 9 keyed to the axles of the wheels 6, and sprockets 10 keyed to a hollow shaft 11 driven by a motor 12 through a torsion bar 11a extending through the shaft 11 and coupled thereto through gearing 13. The upper runs of the chains 8 pass over a sieve table 14 comprising a perforated sheet through which passes fine earth which becomes removed from the sods. Outwardly inclined guide plates (not shown) are preferably provided at the front sides of the elevators to guide sods which would otherwise pass between adjacent elevators into the path of the elevators.

Abstract: 1,191,341. Spanners. WILKINSON SWORD Ltd. 1 Feb., 1968 [4 Feb., 1967], No. 5479/67. A hand-tool e.g. adjustable spanner, comprises a variable-position pivot whose position is determined by its abutment with a multiple abutment element. A pivot pin 20 secured to an integral handle-jaw 10, 12 is slidable in a slot 21 in a second integral handle-jaw 11, 13 the length of the slot being adjusted by a stepped cam 22 normally biased in such a way as to limit the slot to a length corresponding to minimum closure of the jaws 12, 13. The cam is so biased by a leaf spring 32 actuing on a lever 27 having a pin 26 co-operating with a slot 25 in the cam. The force of the spring may be compensated, in use of the tool, by depression of a button 29 at the end of the lever remote from the cam, whereby the position of the cam alters and the length of the slot 21 is increased. Ends of the handles remote from the jaws are biased apart by leaf springs 33, but the extent of their opening is limited by a stop arrangement 34.

Title: Light transmissive electrically conducting optical articles suitable for use as a lens, a window or windshield, or the like
IPC: C03C27/12
Filed: 1950-03-06
Abstract: A transparent article, such as a lens, window or windshield, comprises a body of glassy silicious material having a smooth continuous surface, a transparent interlayer of metal compound applied to the smooth surface and an electrically conductive, continuous metal outer film, having resistivity of not more than 150 ohms/square and of uniform thickness such that the light conductivity of the article is at least 50 per cent a heating current being passed through the metal film to prevent misting or icing of the article. The outer film is Au, Ag, Cu, Fe or Ni and the interlayer, which is 4-108 A DEG  thick, is an oxide of Pb, Ag, Al, Mg, Ni, Zn, Cd, Sb, Bi, Hg, Cu, Au, Pt, Pd, Th or rare earth metals, or the sulphide, sulphate, selenide, selenate, telluride, tellurate, or fluoride of these metals.  The outer film is preferably applied by thermal evaporation.  The interlayer may be applied by direct thermal evaporation, e.g. in the case of the oxides of Pb, Cd, Zn, Sb, Al and the sulphides of Zn, Pb, Sb and Mg F, or in the case of Al2O3, PbO and CuO, by evaporating a metal layer and oxidizing by glow discharge in partial vacuum.  Alternatively, oxidizable metal and materials (e.g. metallic sulphides) may be applied and then oxidized by heating in air at high temperatures to form the interlayer.  The interlayer may also be formed by sputtering metal, e.g. Cu, Ni, Ag, Au, Pd or Pt, in a partial vacuum, thus forming an oxide coating directly.  An interlayer of PbSo4 may be formed by thermally evaporating PbS and then exposing it to air to oxidize it.  A protective layer of SiO2, Al2O3 or MgF may be applied to the metal film and, where SiO2 is used, a further interlayer of metallic oxide is interposed between the SiO2 and the metal film.  In one example, successive coatings of Al. Au, Al were built up on glass by thermal evaporation and the Al coatings oxidized in a furnace.  A further protective layer of SiO2 was applied to the Al2O3 layer and the coated glass laminated with uncoated glass to form a windshield with the metal film on the inside of the lamination.  Alternatively, the windshield may be made using a gold oxide interlayer and a gold film and laminated with uncoated glass.  Specifications 605,871, 605,872 and 605,873, [Group XX], are referred to.

Title: Storage register control mechanism
Inventor: DUBS PAUL
IPC: G06K15/06
Filed: 1968-07-19
Abstract: 1,248,250. Decimal/binary encoders. S.C.M. CORP. 19 July, 1968 [21 July, 1967 (2)], No. 5605/71. Divided out of 1,248,247. Heading G4B. The description is substantially identical to Specification 1,248,247 but the claims are directed to a mechanical storage register comprising a set of ordinal gears each of which are rotated in turn through idle gears by a second set of gears having numbers of teeth arranged in a binary progression. Depression of any key 0-9 on a keyboard (Fig. 1, not shown) causes through a linkage a combination of switches to be operated which energize a corresponding number of electromagnets 301a-301c thus releasing one or more gears 321a-321c which transfer parts of rotation of a shaft 307 through gears 306a-306c angularly arranged on a drum 306 having numbers of teeth arranged in a binary progression i.e. 1, 2, 4, 8. Drum 306 is connected through an electromagnetically controlled single revolution spring clutch 308 to a constantly rotating shaft. When a rightward movement of shaft 320 occurs each of gears 321a-321d not held back by arms 325a-325d is aligned with a corresponding one of binary gears 306a-306d hence angular rotation is transferred to a converter shaft 320 turning a gear 333 in mesh with an entry gear 366. An escapement drum 358, Fig. 16, is driven by a gear 359 in mesh with single tooth gear 361 so that stops 358a arrest in steps the leftward movement of carriage 340, propelled by rotation of a wind-up drum 355, cord 362 and spring 364, so that storage gears 351a-351n mesh in turn with entry gear 366, each storage gear being rotated an amount depending on the decimal number set on the keyboard. An indicator drum 356 displays through a window (119 not shown) a number representative of the digit set up. Except when any storage gear is in mesh with entry gear 366 it is locked by two sections of a stationary gear flank 331, 332 disposed on opposite sides of gear 366 thus locking gears 351a- 351n against rotation both before and after information is stored. In addition detents (374, 375, Fig. 15, not shown) acting as "click stops" are provided which prevent unwanted rotation of shaft 320 and entry gear 366. After a complete series of decimal digits is stored, the contents of the register comprising gears 351 are transferred to a bank of print wheels (501) which involves pivoting carriage 340 to an output position where the contents of gears 351 are simultaneously transferred in parallel to a print wheel (501 not shown) (see Heading B6F).
