Title: Coded data recovery apparatus
IPC: H03K3/013
Filed: 1970-06-25
Abstract: 1322758 Pulse shaping circuits BRITISH AIRCRAFT CORP Ltd 13 Aug 1971 [25 June 1970] 30934/70 Heading H3P Apparatus for recovering a periodic signal from a degraded input signal comprises: means for sampling the input signal and generating a pulse whenever the sampled signal has a predetermined polarity with respect to a reference level; means controlled in accordance with the periodic frequency of the input signal to control the sampling means so that the input signal is sampled at least three times in each period; and a counter receiving the generated pulses, and being responsive to the total count in each period to indicate the polarity of the input signal in that period. Degraded data input signals are applied to threshold switches J, K which apply a " 1 " to the set or reset inputs of bi-stable Tl whenever the input signal exceeds limits +V and - V respectively. A clock signal at the data transmission rate is derived either by a conventional clock extraction circuit, or, in the case of the data coming from a tape, from a separate clock track, and is applied to multiplier M which produces 128 sampling pulses during each clock period. These pulses are fed via an INHIBIT gate I to a divider C1 which closes the gate I after 64 pulses have been counted. The 64 pulses passed by gate I are applied to the trigger input of bi-stable T1 to set it to a state determined by the signals from thresholds J, K. Whenever the bi-stable T1 produces a " 1 " on its Q output, gate E is enabled and the pulses from gate I are fed via delay D1 and gate E to counter C2, which can count up to 64. If during a clock period, more than 32 pulses are counted, C2 produces a " 1 " output which allows bistable T2 to take up a " set " state, indicating that the data input pulse is probably positive, since less than half the samples were less than +V. Conversely if less than 32 pulses are counted, C2 produces a " 0 " output, and bistable T2 takes up a " reset " state, indicating the probability of a negative input pulse. The reference levels may be zero.

Title: Analyser for measuring x-radiation
IPC: G01T1/16
Filed: 1971-08-16
Abstract: 1323238 Measuring X-radiation photoelectrically K V ANISOVICH D A GOGANOV and N I KOMYAK 16 Aug 1971 38312/71 Heading G1A An analyzer for measuring X-radiation in a pre-selected energy range comprises a filter 1 including a first material having an absorption edge energy corresponding to the upper limit of the pre-selected energy range; a main radiator 2 made from a second material having an absorption edge energy corresponding to the lower limit of the energy range; a main detector 3 receiving radiation from the main radiator; an additional radiator 4 including the said first material; and an additional detector 5 receiving radiation from. the additional radiator and connected with the main detector so as to give a difference signal indicative of the intensity of X-radiation in the pre-selected range in the incident beam A. By proper selection of the thicknesses of the radiators any response in the main detector due to the incidence thereon of radiation outside the preselected range is cancelled out in the differential process by a corresponding response from the other detector. The detectors receiving fluorescent radiation from the radiators may be gas-filled or proportional counters or Geiger-M³ller counters. The filter 1 and radiator 4 may each comprise two materials in laminar form. The additional material is one having an L-edge of absorption located between the K-edge of the first material and the K-edge of a material having an atomic lumber a unity less than that of the first material. Protective shields 8 prevent X-rays from the filter 1 impinging directly on the detector 3. The X-radiation being examined may be excited by means of a low-power X-ray tube.

Abstract: 1350202 Copying oscillograph data SHANDON SOUTHERN INSTRUMENTS Ltd 19 April 1971 [27 Feb 1970] 9693/70 Heading G2A Oscillographic data recorded on a film-strip 3 is copied on to a web 4 of photo-sensitive material by means of a beam of light which passes through the strip 3 and scans it in a direction transverse to its direction of movement. Both strip 3 and web 4 move in the same direction, and if web 4 moves faster than strip 3 an extended time scale is produced. The light beam may be provided by an ultraviolet source 2 and is reflected by a moving mirror 1 to scan transversely across film-strip 3. The mirror may be part of a galvanometer. Another method of transversing the light beam across strip 3 is by passing it through a slot in the shape of an involute curve in a rotating disc.

Inventor: ROMANSKI ERIC R
IPC: D21F3/02
Filed: 2000-05-16
Abstract: A resin-coated endless belt (16) for a long nip press(10) has a base which is a polymeric film structure in the form of an endless loop with an inner surface (52), an outer surface (54), a transverse direction and a longitudinal direction. The polymeric film structure has a plurality of perforations (56) which may be aligned in one or both of these directions. The polymeric film structure is stretched in the presence of heat to orient the molecular chains in the unperforated intervals between the perforations to provide the structure with tenacity and resistance to further stretching. At least the inner surface (52) of the base (polymeric film structure) is coated with a polymeric resin material, such as polyurethane. The polymeric resin material coats the base and upon curing, forms a mechanical interlock therewith by virtue of the perforations, and renders it impermeable to oil and water. In addition to being useful for a long nip press, the belt may also be used in other papermaking applications, for example, as a calender belt on a calender of the shoe type or on a calender having two or more rolls, or as a transfer belt. <IMAGE>

Title: Method and apparatus for the formatting of data for transmission
IPC: H04W72/04
Filed: 1993-01-15
Abstract: The invention relates to a communication system in which transmission takes place according to a format which permits different types of data to be combined and transmitted within a single transmission. The novel feature is that the communication system transmits variable length frames of data in packets, and that a data combining and transmission sub-system (14, 16, 18, 20) is provided so that when a frame of data does not require a complete packet for transmission, the data combining sub-system combines the frame of data with additional data to provide a complete packet. The data combining sub-system comprises input means for receiving the frame of data and the additional data and for combining the frame of data and the additional data to provide a complete packet responsive to a control signal, and control means for providing the control signal. <IMAGE>

Title: Ceramic-like materials and their preparation
IPC: C08L63/00
Filed: 1994-06-24
Abstract: This invention is concerned with a process for preparing ceramic-like materials suitable for a wide range of application, by binding an inorganic filler of a grain size of up to 20  mu m, used in the form of phosphogypsum or phosphogypsum and magnetite, or phosphogypsum and glass-forming oxides, with epoxy resin or a mixture of epoxy resin and polyester resin, the latter amounting to 80 % by volume, with the volume ratio of the resin component to the filler being 1:0.45-2. The resultant ceramic-like materials are water resistant and can be easily formed, also by casting, and additionally by mechanical working, if required. The ceramic-like materials containing magnetite show magnetic properties, while those containing glass-forming oxides are able to absorb an X-radiation of 45-55 keV and a hard radiation of 0.6-1.25 MeV. The addition of an expanding agent such as butyl isocyanate to the raw composition makes it possible to prepare an expanded material with completely closed pores. Due to very good adhesion of the ceramic-like to metal, glass, plastics, concrete it can be easily joined with these materials both during the polymerization process and after its termination, also by using a prepolymerized composition as a binder.
