Title: Improvements in actions for typewriting machines
IPC: B41J7/02
Filed: 1922-03-29
Abstract: 198,840. Hess, E. B., and Royal Typewriter Co., Inc. March 29, 1922. Type-lever actions.-In noise-reducing actions adapted to complete the stroke of the type-levers by momentum, the momentum stroke is rendered uniform for all the type-levers, by attaching the actuating-members of the type-levers at different points from the centre to the sides of the system. As applied to the action described in Specification 182,427, the actuating-links of the middle typelevers are connected to the heels of the type-levers at points vertically beneath the type-lever pivot. whilst the actuating-links of the side type-levers are connected to the heels at points to the rear of the vertical line through the pivot. To avoid return movement of the key-levers during the momentum stroke, the action may include a yielding member; for instance, the actuating-link N, Fig. 2, of the type-lever D may consist of a closely-wound spring n connected to rods n<1>, n<2>, the spring stretching during the momentum stroke. In the action shown in Fig. 3, typelevers D mounted on an oblique segment Bare connected by links N, O to key-levers F, the links O being connected also to levers L. On depressing the key-levers, the links O and levers L come to the dead-centre position when the typelevers reach the position x<1>, and the stroke of the type-levers is completed by momentum, aided by gravity. In the action shown in Fig. 4, the typelevers D are connected by links N to levers N<1> having inclined slots n<1> engaging rollers n<2> on the key-levers F. The levers N<1> at the sides of the system are longer than those at the middle. The links and the type-levers come to the dead-centre position when the key-levers are depressed, and the stroke of the type-levers is completed by momentum. The levers N' prevent the typelevers from rising or rebounding from the rest E. The rest is secured to a plate A' formed with a comb for the key-levers, and a dust-shed a. Keys.-The returning-springs R, Fig. 3, for the levers L are connected to a rocking plate R<1> which can be adjusted by means of an eccentric s to vary the touch. An extension of the plate may form a comb for the key-levers F. Letter-spacing mechanism. - Universal-bar mechanism is operated during the momentum stroke of the type-levers. In one arrangement, the heels of the type-levers are connected to rearwardly-directed links having hooks which engage a universal bar during the momentum stroke of the type-levers. In the arrangement shown in Fig. 3, a universal bar Q at the front of the machine is carried by levers q connected by links V, Y and a lever V<1> to the dog rocker e<3>, the universal bar being engaged by the links O during the momentum stroke. The escapement mechanism and the link Y are shifted with the platen. In the arrangement shown in Fig. 4, a universal bar Q is carried by levers q connected by links R<3>, T<4> and a lever R<4> to the dog rocker, the type-levers being connected to links C<2> having hooks C adapted to engage the universal bar during the momentum stroke.

Filed: 1971-04-08
Abstract: 1,272,377. Wells &c. TEXACO DEVELOPMENT CORP. 9 April, 1971, No. 9147/71. Heading E1F. Oil is produced from an underground reservoir by: (a) producing the reservoir by solution gas drive; (b) terminating the solution gas drive when the pressure of the reservoir is below the bubble point pressure but within the critical gas saturation; (c) injecting water into the reservoirwhile maintaining reservoir pressure and simultaneously producing the reservoir; (d) terminating the water injection when the rate of oil production has reached a predetermined termination point; (e) producing the reservoir by solution gas drive; (f) terminating the gas drive when the pressure of the reservoir is below the bubble point pressure but within the critical gas saturation; (g) injecting water into the reservoir while maintaining reservoir pressure and simultaneously producing the reservoir; (h) terminating the water injection at a predetermined point; and (i) repeating steps (a)..(h) until the abandonment pressure of the reservoir is reached. The predetermined points are indicated by a rapid rise in water production compared with the rate of oil production. Where the reservoir is undersaturated the step of solution gas drive is preceded by gas injection into the reservoir to establish a gas saturated reservoir capable of solution gas drive. Thickeners may be mixed with the injection water.

Title: Radio receiver
IPC: G01S1/02
Filed: 1944-05-12
Abstract: 592,495. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. May 12, 1944, No. 9178. Convention date, May 21, 1942. [Class 40 (v)] The invention relates to systems of the kind in which a carrier frequency is modulated by intelligence and in addition, is regularly swept through a certain range of frequencies. Fig. 2 shows a receiving arrangement of this kind in which the carrier wave is periodically swept through a definite frequency range in accordance with a saw-tooth pattern. The input circuit 18 has a response band wide enough to include the carrier fluctuations, and feeds a mixer 19 supplied from a local oscillator 20. The I.F. amplifier 21 is fed through a coupling circuit 22 having a narrow pass band, and feeds a detector 23 and subsequent A.F. stages (not shown). To produce a constant I.F. the frequency of the local oscillator 20 is varied in accordance with the fluctuations in the incoming carrier wave by means of a saw-tooth oscillator 24 and reactance valve 26. The natural period of oscillator 24 is slightly greater than that of the carrier frequency fluctuations. Thus, at the end of each fluctuation, the sudden change in carrier frequency produces a sudden change in output from the detector 23 which is used to trigger oscillator 24 and maintain synchronism. In the embodiment of Fig. 3, a wide band auxiliary receiver 30 feeds a frequency detector 31 to obtain a control potential which varies in accordance with fluctuations in carrier frequency. This control potential is applied to vary the reactance of circuits 32, 32<1> to vary the tuning of a narrow band input circuit 33 of the main signal receiver, and to vary the local oscillator 35, so as to produce a constant I.F. The invention may be applied to aerial navigation systems such as that described in Specification 563,076 to minimise errors due to reflection.

Title: Improved signalling method for establishing trunked communication
Inventor: SASUTA MICHAEL DAVID
IPC: H04W84/08
Filed: 1997-06-26
Abstract: A trunked communication signalling method is provided by a unifying signalling protocol in which subscribers request communication channels using only their individual IDs encoded into a single ISWs. The central decodes the call request, extracts the requesting subscriber's individual ID, which is cross referenced to determine the subscriber's talk-group affiliation(s). If the requesting subscriber's affiliation(s) are not known, the central commands the subscriber to transmit its affiliation using dual ISW signalling. In another aspect of the present invention, each subscriber automatically informs the central of a change in talk-group affiliation, thereby providing continual affiliation updates. In this way, many thousand subscribers are afforded access to a single trunked system, and control channel traffic congestion is minimized.
