Title: Improvements in or relating to colour photography
IPC: G03C7/388
Filed: 1937-10-05
Abstract: 505,834. Colour photography. MARTINEZ, M. Oct. 5, 1937, No. 26966. [Glass 98 (ii)] The action of colour formers in colour photographic material is localized by means of a natural or artificial resin or gum resin not chemically combined with the colour former but in intimate physical association with it. The colour formers such as alpha-naphthol or p-nitrobenzyl cyanide may be dissolved in a non-aqueous solvent, such as acetone or a mixture of acetone.and alcohol, together with the resin or gum resin, such as colophony and gum mastic, and the mixture added directly to a silver halide emulsion or to a gelatine solution which is afterwards added to the emulsion. Other resins and gum resins referred to are gum dammar and gum sandarach. In an example, p-nitrobenzylcyanide is employed as the colour former, and gum mastic as the resinous body. The colour formers may be incorporated in material comprising two or three differently colour sensitized layers on one or both sides of a single support or on separate supports. One layer may not contain a colour former and may be toned to the appropriate colour after development. The Provisional Specification describes also the use of a mixture of alpha-naphthol and gum mastic.

Title: Improvements in or relating to vehicle detectors
Inventor: WOODLAND CECIL ROBERT
IPC: G08G1/02
Filed: 1948-10-21
Abstract: 653,900. Air compressors. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 21, 1948, No. 27350. [Class 8(i)] [Also in Group XXXVIII] A pressure-responsive device for detecting the passage of road vehicles thereover comprising a resilient tread member having a fluid-filled longitudinal cavity is so arranged and dimensioned that the said member is firmly retained in position but may be readily removed and replaced, also that with vehicle wheels of normal size the cavity is sufficiently compressed to effect operation of detecting equipment but the upper and lower surfaces of the cavity are not brought into contact. Channel-shaped mild steel members 13, 14 and' 15 are mounted on brackets 19 and bars 20 for insertion in a cavity in the road such that the tops of the channels are level with the road surface and are secured together in longitudinal alignment by plates 18, thereby providing sufficient flexibility for the whole structure to follow the camber of the road surface. Two channel members are conveniently mounted on a bracket 19, as shown in the end view of Fig. 3, to provide the usual two detector members for unidirectional detection. The limbs of the channel members are bent slightly inwards to retain a correspondingly shaped resilient tread member 24, preferably produced by an extrusion process, having a longitudinal air-filled cavity 25. The size of the cavity in relation to the distance apart of the enclosing limbs is such that in use it will never be closed completely. A junction box 21 is provided at one end of the device for connection of a rubber tube from detecting equipment to the end of each tread member cavity, and has a stout lid 22 having extensions covering the end of the tread members which are suitably cut away to fit. At the opposite end of the device the channel members are closed by L-shaped pieces 16 and 17 welded in position with their horizontal arms flush with the tops of the side limbs, the tread members being again cut away to fit thereunder. Rubber plugs 26 and 27 are bonded into the ends of the tread members cavity to make air-tight closures, and a short vertical bore 28 closed by a similar plug 29 serves for connection to the cavity by means of a horizontal metal tube 30, Fig. 5 (not shown), to the outer end of which is fitted the rubber tube extending to a capsule of the type disclosed in Specification 631,788, [Group XXXVII], which closes an electric contact when a pressure impulse is produced by passage of a vehicle over the tread member. By first removing the cover 22 of the junction box 21 a tread member may be readily peeled out of its containing channel if necessary. Detectors of short length only may be made by a single solid casting having two parallel undercut grooves for reception of the tread members, as shown in the drawing accompanying the Provisional Specification.

Title: Improvements in or relating to apparatus for transmitting and receiving signals by modulated oscillations of constant amplitude
IPC: H04B14/00
Filed: 1962-07-17
Abstract: 958,630. Frequency modulation; automatic frequency control. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 17, 1962 [July 20, 1961], No. 27435/62. Headings H3A and H3R. In a frequency modulation transmitter and receiver, means are provided for compressing the range of the modulating signal at the transmitter by negative feedback over the modulating stage and expanding the signal range at the receiver. An audio signal is applied via a preemphasis circuit 2, amplifier 3 and adder circuit 15 to a frequency modulating stage comprising reactance valve 4 and oscillator 5 and the resulting modulated signal is applied via limiter 6 to a transmitter output stage 7. The output of the limiter is also applied to a ring type amplitude modulator 13 and to a discriminator 10. The output of the discriminator is rectified to provide a D.C. output signal which varies with the change in deviation of the transmitter signal and this voltage is applied via a low pass filter 12 to modulate the amplitude modulator 13. Assuming a change in deviation at the output of the limiter the amplitude modulator provides a frequency modulated signal which is also amplitude modulated by this change and this signal when applied to discriminator 14 produces a signal in which the change is proportional to the square of the change in deviation. This signal is applied as negative feedback to the adder circuit 15. The feedback is sufficient to ensure that any change in the audio signal at the output of amplifier 3 produces a substantially equal change in the feedback voltage and since this voltage is proportional to the square of the deviation change at limiter 6, this condition can only be met by compression of the deviation change to a value proportional to the square root of the change at the output of the audio amplifier. The feedback circuit also acts to stabilize the frequency of the transmitter. At the receiver the incoming signal is applied via mixer 19, I.F. stages 21, 22 and limiter 23 to a ring type amplitude modulator 31 and to a similar discriminator, rectifier and low pass filter arrangement 28, 29, 30 as that provided at the transmitter which supplies a D.C. signal which varies with change in deviation of the incoming signal. The signal amplitude modulates the F.M. signal and the resultant signal is applied to discriminator 32 to produce an output in which any change is proportional to the square of the corresponding change in deviation. This signal is applied via amplifier 25 and deemphasis circuit 26 to a speaker 27.

Title: Improvements in connection with detachable covers for bicycle and other saddles or seats
IPC: B62J1/18
Filed: 1923-11-01
Abstract: 226,327. Marr, L. T. Nov. 1, 1923. Saddles and seats. - A detachable cover for the saddles or seats of bicycles, agricultural machines &c., applicable also to horse Rc. saddles, comprises the combination of a shelllike casing A provided about its edge with an inextensible tension member D adapted to be tightened to contract the casing edge within the underside of the saddle top, and a cushion or pad E of spongy or resilient material which is enclosed within the casing and is fashioned to an exaggerated anatomic shape so that when the cover is fitted the pad is more compressed at the sides and rear, as at E<1>, and consequently has different degrees of resiliency at different areas. Towards the rear the casing has extensions A<2> so that when strained the tension member passes well within the flaps or wings of the saddle. As shown, the tension member or cord D, passing round through the coils of a flattenedcoil wire spring C sewn to the casing edge, on each side towards the front passes outwards through a hole in the casing and lies within the channel of a V or U-shaped spring B secured to the peak of the casing. The spring C may, however, be replaced by rings, clips, &c. secured to the casing edge, or by eyeletted holes or slots cut in the material, and, for tightening the cord, its ends may be secured to tubes which are adapted to be drawn by screws into the tubular limbs of a V or U shaped spring at the peak. In the case of a cycle saddle for ladies' use a curved piece or adaptor is placed over the saddle peak and this curved piece is grooved on its outside to receive the V or U shaped spring carried by the peak of the casing; the tightening of the cord fixes both the adaptor and the cover in position. The casing and pad may be separate parts, or the pad may be moulded within the casing or attached thereto as by a solution of rubber &c. When separate from the casing the pad may have transverse bands terminating in clips or hooks for securing the pad to the saddle before the casing is fitted.
