Title: Double textile protective material
Inventor: ALEKSANDROV SASHO P
IPC: A62D5/00
Filed: 1991-02-07
Abstract: This material is used for protective clothing. It is resistant to strong acids, bases and oxidants, retains its physio-mechanical indicators, its water-, wind-, oil- and gasoline-resistance, and gas non-promiscuity. The material is derived from cotton or cotton-polyester tissue (with an aerial mass 80-120 g/m) by lubrication according to familiar methods with an alloy from polyethylene, or by thermal gluing of polyethylene film, with a thickness between 10 and 500 mkm. A polyethylene with low density (up to 0.925 g/cm<3>) is used. The sewing of the clothing is conducted following classical methods, while the stitches are glued thermally with polyethylene folio.

Patent CA-2003428-A1 (CA)
Title: Frequency synthesizer
Inventor: RILEY THOMAS A D
IPC: H03L7/197
Filed: 1989-11-21
Abstract: An indirect frequency synthesizer suitable for use in a cellular radio system has finer resolution and reduced spurious frequencies and/or phase noise, which facilitates a large number of channels in a given bandwidth. The synthesizer comprises a phase detector responsive to a reference signal and a phase control signal for generating a control signal that varies in dependence upon the phase difference between the reference signal and the phase control signal. A voltage controlled oscillator responsive to the control signal generates an output signal whose frequency varies in dependence upon the control signal. A variable modulus divider divides the output signal to provide the phase control signal. The variable modulus divider varies its division ratio in dependence upon a ratio control signal derived by a second or higher order sigma-delta modulator in response to a frequency control signal .delta..PHI. and to the phase control signal.      The sigma-delta modulator displaces any quantisation noise in the ratio control signal away from the frequency of the phase control signal and multiples thereof. A direct frequency synthesizer may be implemented by means of the same sigma-delta modulator and variable modulus divider, but arranged so that the reference frequency signal is applied to the input of the divider, which divides it directly to provide the desired output frequency.

Title: Method and apparatus for producing a composite pipe in a rotating drum
Inventor: HARTMANN PETER
IPC: F16L21/00
Filed: 1989-12-22
Abstract: A B S T R A C T     The components forming the layers of the composite pipe are successively introduced into a rotary drum (1).  Firstly a plastics reinforcing layer (8) with a fibre reinforcement is introduced, the ends of the drum (1) being bounded by rings.  The concrete core layer (16) is then introduced and by shaping rings fixed to the drum ends the length of the core layer (16) is shortened compared with that of the drum (1).  The shaping rings are then replaced by other shaping rings (20, 21).  Thus, on either side of the core layer (16) two annular spaces (22, 23) are formed, which are filled by a socket material (24, 25) of the same composition as the reinforcing layer (8).  Thus, at one pipe end a socket end (28) is formed and at the other pipe end a spigot end (30), which are located within the composite pipe wall thickness.  After introducing a second reinforcing layer (26), the production of the composite pipe is ended.  By producing the socket connecting elements (28, 30) simultaneously with the construction of the composite pipe, a reliable and rational production of the composite pipe with its socket connecting elements (28, 30) is achieved.  By shaping a shoulder (33) on to the spigot end (30), on sliding together two composite pipes the socket end (28) is centred.  Simultaneously an annular space (34) is formed, in which can be inserted an elastic seal (35) for drip-tight sealing.                                                  (Figs. 3 and 5)
Patent CA-2006803-A1 (CA)
Inventor: LANDT JEREMY A
IPC: G01S13/82
Filed: 1989-12-28
Abstract: Briefly, the range limiting system of the invention is capable of differentiating desired received signals having an amplitude above a predetermined threshold level and at least one other recognizable predetermined characteristic, from other received signals below that predetermined threshold amplitude.          The system has a means for combining the received signal, which is of unknown amplitude which may be above or below the predetermined threshold amplitude, with a known signal of the predetermined threshold amplitude having at least one other predetermined characteristic which is distinguishable from the other recognizable characteristic of the received signal.  The output of the combining means passes to a signal processing means which produces an output signal whose other recognizable characteristic is determined by the received signal only when the received signal is above the predetermined threshold amplitude, and by the known signal when the received signal is below the predetermined threshold amplitude.  The presence or absence of the desired signal is determined on the basis of analysis of the other predetermined characteristic of the output signal of the signal processing means.
