Title: Gain Control Circuit for High Frequency and Intermediate Frequency Stages in Radio or Television Receivers
IPC: H03G3/20
Filed: 1982-02-17
Abstract: In a superheterodyne circuit for a radio or television receiver comprising a radio frequency stage (3), a mixer stage (4) and a gain regulating stage (7) for controlling the signal supplied to an intermediate frequency stage (6), the control signal for the regulating stage (7) is derived from an automatic gain control circuit (9) likewise connected to the mixer (4) and a regulating signal for the radio frequency stage (3) is provided from the automatic gain control circuit (9) by way of a threshold value circuit (10). The arrangement is such that the control of the radio frequency stage (3) by way of the threshold value circuit (10) only commences after a predetermined range of regulation, for example about 10 db, has already been effected by the regulating stage (7). The regulating stage 7 may comprise PIN diodes or a field effect transistor. <IMAGE>

Title: Buoyancy-actuated reciprocating movers
Inventor: STEVENSON JAMES ARNOLD
IPC: F03B17/02
Filed: 1982-12-22
Abstract: A body 2 is immersed in water 10, and provides a chamber 3 which communicates with a pipe 5 incorporating a U-bend 6. An air stone 13 provides a continuous stream of bubbles 15, which float upwards into the chamber 3. As the chamber 3 progressively fills up with air, the body 2 rises towards the surface 11 of the water 10. Eventually, the free end of the pipe 5 rises above the surface 11, and the pressure prevailing within the chamber 3 clears the U-bend 6 to vent the chamber 3. Thereupon, the body 2 again sinks to become immersed within the water 10. The body 2 reciprocates up and down in this way, as long as the stream of air bubbles 15 is provided. The movement of the body 2 is utilised to pump water around a circulation and filtration system of a fishpond (Figure 5). <IMAGE>

Title: Measuring device for detecting and monitoring the filling level of centrifuges
Inventor: BRESSERT EDGAR
IPC: B04B11/04
Filed: 1984-08-30
Abstract: In a measuring device for detecting and monitoring the filling level of centrifuges in electrochemical deburring plants, which centrifuges are used for separating the metal hydroxides, produced during the deburring process, from the electrolyte and the filling volume of which is proportional to an electrically detectable measurement quantity, a voltage (U) which is proportional to the workpiece-machining current serves as the measurement quantity. This voltage is converted by means of an electronically controlled voltage/frequency converter (3) into a signal sequence (f1 and f1', respectively) having a voltage-proportional frequency and the signals are counted in a counting device (5). The constant of proportionality between the measurement voltage (U) and the signal frequency (f1 or f1', respectively) is variable so that the counting device (5) can indicate the operating current of the plant in the desired unit, for example in A/h. <IMAGE>

Title: Microencapsulation of viable cells
Inventor: JARVIS ALLAN P
IPC: C07K16/00
Filed: 1984-08-31
Abstract: A process for damage-free encapsulation of a variety of core materials including viable cells involves suspending the core material in an aqueous solution of a polysaccharide containing cationic groups, such as an aminated glucopolysaccharide. A temporary matrix is formed by gelling droplets of the suspension using a solution containing a divalent or multivalent anion. The temporary matrix is permanently cross-linked with a polymeric material containing plural anionic groups, e.g., polyaspartic or polyglutamic acid, to form a semipermeable membrane.

Title: Sweeping machine
Inventor: OAKLEY ROBERT
IPC: A47L11/24
Filed: 1985-04-04
Abstract: A sweeping machine consists of a frame 10 for pivotal mounting on the tines 27 of a fork lift truck. The pivot 25 is positioned on the frame 10 such that raising the machine above the ground causes it to swing about the pivot 25 allowing posts 30 on the frame 10 to abut the underside of channel members 26 in which the lines 27 are located. The frame 10 supports a cylindrical brush 14 and a collecting box 12 located forward of the brush 14. The brush 14 is driven by a rear road wheel 20, such that it rotates in an opposite sense to that of the road wheel 20. Jockey wheels 18, located forward of the pivot 25, support the front of the machine and cooperate with the road wheel 20 and frame pivot 25 to accommodate changes in the ground level. The brush 14 is mounted on arms 11 which are pivotally secured to the frame 10 and adjustable such that their attitude may be changed in order to alter the level of the brush 14 with respect to the frame 10. The contents of the collecting box 12 may be quickly removed by raising the entire machine above a suitable hopper and unlocking a hinged bottom 31 in the collecting box 12. Such a machine mounted on a fork lift truck provides a versatile and economical method of sweeping large spaces such as warehouses and shopfloors. <IMAGE>

Title: Laser surgery
Inventor: HERMAN STEPHEN JACK
IPC: G02B6/42
Filed: 1986-02-28
Abstract: A catheter is used to controllably apply radiant energy in a patient's body, such as in a blood vessel to drill through vascular obstructions. The catheter emits the radiant energy from its distal end in a pattern which defines a relatively small working region in which the energy density level is sufficiently high to remove the biological material but beyond the working region, the energy density of the beam decays sharply so that biological material beyond the working region is not removed and the beam will not have sufficient energy density to puncture the blood vessel wall. The catheter is a of elongate flexible tubular construction having a fiber optic wave guide which terminates within the catheter and is secured in alignment with an optical system at the distal end of the catheter. The catheter includes openings adjacent the distal end which communicate with the lumen and enable delivery of fluid to the blood vessel or withdrawal of material from the blood vessel.
