Abstract: 1,183,827. Leather substitutes. SOC. RHODIACETA. 4 May, 1967 [4 May, 1966], No. 20733/67. Heading B2E. A leather substitute consists of a film of synthetic polymer adhering to a base textile sheet formed of organic continuous spun bonded filaments disposed at random in non- parallel fashion throughout the sheet and having a count between 1 and 10 denier and substantially free from non-fibrous resinous material, the film making up 50 to 90% of the total weight of the material. The continuous filaments may be of polyethylene terephthalate or isotactic polypropylene. The film may be a polyvinyl chloride. The polymer may be deposited while the sheet is under longitudinal tension, the synthetic polymer having not yet been gelled, gelling the polymer layer, calendering, cooling and releasing the tension on the sheet, depositing on the resultant assembly a further layer of synthetic polymer which has not yet been gelled and gelling the second layer of polymer. The first and second layers may be of the same chemical nature and in the case of a plastisol the first layer deposited may contain more plasticiser than the second.

Abstract: 1283421 Systems depending on two supplies G W PLUMLY and J B HUNNICUTT 30 April 1970 [8 May 1969] 20863/70 Heading H2H [Also in Division G5G] In a teaching machine (see Division G5) a control circuit, Fig. 12 (not shown) is embodied in a unit having an internal power supply. Provision is made for temporary operation from an external power source should the internal supply fail, the act of fitting the external source being made to cause a permanent disconnection of the internal supply so that it must be replaced before normal operation can be restored. The internal supply consists of a battery 191, Fig. 13, in series with a fuse 359, the load (i.e. the control circuit, not shown) being permanently connected to the points 357 and 361. The unit has three terminals 367, 368, 369 and the external supply source, a battery 371, has three corresponding terminals 373, 375, 377. The third terminals 369 and 377 are connected to opposite sides of the two batteries so that, on first plugging in, the internal battery is short-circuited and the fuse is therefore placed directly across the external battery. The fuse blows, thereby connecting the external battery to the load and permanently disconnecting the internal one.

Title: Tractor mower
IPC: A01D34/86
Filed: 1946-07-12
Abstract: 614,374. Mowing-machines. DEHN, S. G. (Minneapolis-Moline Power Implement Co.). July 12, 1946, No. 20937. [Class 6 (iii)] Relates to power-operated mowers having the cutter unit pivotally mounted so that it may be swung up to different positions by power operated means. According to the invention, the tractor has an additional frame 11 at the outer end of which the cutter is carried, a support for pivotally carrying the frame on the body of the tractor so that the frame extends outwardly from one side and is adjustable about the axis of the pivotal support, a bracket 154, fixed to the tractor body and a power operated assembly connecting the frame with the bracket for adjusting, by said power operated assembly, the frame and cutter about the pivotal support. The frame 11 is lifted by a tubular roll 12, the angle of which to the horizontal may be varied by a pin and slot mechanism (see Fig. 2, not shown), actuated by a hydraulic jack 148, Fig. 5. The cutter bar 45 is driven by an eccentric 63 on a shaft 35 connected by a rack shaft 66 and levers to the inner end of the cutter bar. The drive is taken from the shaft H, universal joints 90, 91 to a drive shaft 80 which through a chain 76 and sprocket gears 77, 81 drives the shaft 35, and therefore the eccentric 63, provided clutch parts 64, 65 remain in mesh. A safety release mechanism 96 comprises a pin 97 on a channel 24 of the frame 11, and a pair of bars the upper one, 100, having an arcuate portion which fits tightly around the pin 97, being spring-urged thereto. A tilting mechanism 113 is supported on a pair of bars 114 on the frame 11. A U-shaped bar 122 fulcrummed on bolts 119 is adjustably spring loaded at one end, and connected at the other end by a chain 38 to a sheave member 36. The bar 122 is actuated by means of a hydraulic jack. To allow for a limited up and down movement to compensate for ground variations a stop 151, Fig. 3, is provided in a plate 150, and a spring 160, fig. 5, is included to balance the weight of the cutter, the said spring acting against a pair of plates 164 depending from the roll 12. This mechanism also assists the jack 148 in lifting the frame 11. Oil is supplied to the jacks through a two-way valve controlled from the operator's seat.

Abstract: 149,236. Allgemeine Elektricitõts- Ges. Sept. 17, 1914, [Convention date]. No Patent granted (Sealing fee not paid). Transformers.-In a three-arm choking-coil or transformer, the inductance of which is varied by a winding g carrying continuous current or lowfrequency alternating current, a short-circuited winding k, Fig. 2, is provided for the purpose of protecting the winding g or apparatus connected thereto from undesired tensions, particularly tensions of double, frequency, induced by the alternating-current windings w. The winding k gives rise to fluxes of about the same strength as those induced in the winding g and acts as a damping- coil. In a modified arrangement, Fig. 3, the short-circuited winding is combined with the winding g by providing a short-circuiting resistance R, preferably an ohmic resistance of 10 to 30 times the ohmic resistance of the winding g. The resistance R may in some cases be replaced by a tuned condenser or by a choking-coil of small inductance. The circuit of the winding G may include a choking-coil D, the field winding of a rotary converter, or a microphone for wireless telephony. Specifications 14390/12 and 29946/13 are referred to.

Abstract: 1473301 Registered multi-layer printing NIPPON KOGAKU KK 2 May 1974 [3 May 1973] 21073/73 Heading G2A In the successive production of a plurality of superimposed photo-resist images on a substrate involving successive exposures through respective masks, each mask is provided for registration purposes with fiducial masks corresponding to similar fiducial marks on the substrate, and registration and exposure are effected in such a manner that no photographic images of the fiducial marks on the masks are formed on the substrate. The fiducial marks on the mask and substrate may be superimposed or spaced. The masks may (a) allow or (b) prevent formation of optical images on the substrate. In case (a), when a negative image is being produced, the area of the fiducial mark on the substrate may be uniformly exposed before or after the main exposure, or, when a positive image is being produced, may be protected from exposure by a further mask during the main exposure and covered by a U.V. filter during registration. In case (b), the image of the fiducial mark on the mask may fall outside the area of the substrate or be a fiducial mark 6 on a reflective area 5 which is spaced from a transparent area 2 situated above a fiducial mark 3 on the substrate. Each line of the fiducial marks may be aligned with a reference line with the aid of a respective optical scanner in the form of a photo-electric microscope, Fig. 3. An optical micrometer in the form of a parallel-sided rotatable glass plate 15 enables the use of common reference lines for the mask and substrate.

A combined deflection and E.H.T. supply system of the " flyback " type for cathode-ray tubes comprises a source of energy, a deflection yoke for the tube and a rectifying circuit for the E.H.T., the energy required by the rectifying circuit constituting a relatively large fraction of the energy supplied by the source to both the deflection yoke and the rectifying circuit, and a transformer, the magnetic core of which has an air gap sufficiently large to cause a portion of the energy supplied by the source to be stored in the field surrounding the transformer, this portion being substantially the portion required by the E.H.T. rectifying circuit. The transformer comprises a rod-like dust core secured inside an insulating former on which are placed the windings, the high voltage winding being in the general form of a disc and surrounding the low voltage winding. Further windings, such as valve heater windings, may also be placed on the former. The whole winding assembly is carried by a U-shaped bracket to which is attached a terminal tag board. With the above arrangement, a higher amount of power may be obtained from the E.H.T. rectifying circuit while not producing too high an amount of energy in the deflection yoke.
