Title: Continent ileostomy catheter
IPC: A61F5/445
Filed: 1979-11-01
Abstract: A discharge catheter or tube (30) having a distal end (34) inserted into a continent ileostomy, which uses the peristaltic-created pressure head to produce exiting flow of the intestinal discharge therethrough into a disposable bag (38) attached to its proximal end (36), wherein the flow- inducing pressure is vented to atmosphere at the proximal end to maintain a pressure gradient for the flow. The vented gas can be deodorized. <IMAGE>

Title: Improvements in Hydraulic Pumps
IPC: F04B1/02
Filed: 1979-11-07
Abstract: An hydraulic pump comprises two plungers (15, 16) working in parallel bores (7, 8) and an eccentric drive mechanism (23) acting on the plungers through a common lever (19) which is mounted to rock about a fixed pivot (20). The parallel arrangement of the plungers allows the side thrust imparted by the drive mechanism on the plungers to be minimised. The effective sizes of the plungers can be increased substantially in comparison with known pumps having a radial arrangement of bores. The eccentric drive mechanism (23) acts on the rocking lever (19) through a reciprocating block (28) slidably received in a slot (29) in the lever. The friction of the block sliding in the slot is transferred to the fixed pivot and not to the plungers, thereby avoiding any tendency for the plungers to "scrub" the bores in which they work. <IMAGE>

Title: Slicing machines
IPC: B26D7/32
Filed: 1981-05-05
Abstract: A slicing machine for comestible products comprises a reciprocable feed table (17) for supporting and feeding the product (P) to be sliced by a drivable rotary knife (22) and a slice conveying and distributing device (E) which receives cut slices from the knife (22) and delivers them to a collecting table (23).

This is achieved by driving the conveying and distributing device (E) from the feed table (17) by an endless belt (20), the two runs (20A, 20B) of which each contain an adjustable loop formed by movable pulleys (6, 10) mounted at opposite ends of a guide bar (19). Linear movement of the guide bar lengthens one loop whilst shortening the other so that the conveying and distributing device (E) can be moved. <IMAGE>

Patent GB-2080944-A (GB)
Title: Radiation Intensity Counting System
IPC: G01T1/17
Filed: 1981-07-06
Abstract: A radiation ratemeter circuit excludes the natural dead-time of the detector, eg a Geiger-Muller tube, from the measurement and hence dead-time correction is not needed. Following each detector-actuating event in tube 1 an artificial dead-time, longer than the natural dead-time is applied by pulse generator 4. The circuit aggregates those periods of time other than the artificial dead- times, eg by counting clock-pulses, from clock 7 in register 8 and after a given period of continuous real time, divides the number of counted events in register 9 by the thus aggregated "livetimes" to give a count-rate value free from dead-time error. This value is updated after periods of real time. The latter period may be a defined period of elapsed real time, or may be the elapsed time taken to reach a defined aggregated time. Preferably the detector cannot be activated during the artificial dead time. <IMAGE>

Title: Improvements in or relating to a method of forming a layer of silicon dioxide
IPC: H01L29/51
Filed: 1982-01-20
Abstract: Extremely thin layers of silicon dioxide having very low defect rates are formed on a silicon wafer by first forming a thin layer of silicon nitride, and then oxidizing this thin layer of silicon nitride to silicon dioxide. Because the reaction forming silicon dioxide from silicon nitride is very slow, a substantially defect free layer comprised of silicon dioxide is formed.

Patent GB-2094080-A (GB)
Title: Automatic fine tuning circuits for television receivers
IPC: H03J7/02
Filed: 1982-02-16
Abstract: An AFT circuit for a television receiver automatically adjusts the frequency of a tuner local oscillator 1, not only on the basis of an error signal provided from an AFT discriminator 5, but also on the basis of detection of horizontal synchronizing pulses contained in the video signal to which the receiver is tuned. A synch signal detector 7 detects the presence or absence of the synchronizing pulses. A control circuit 8 provides a control signal of variable pulse width to the local oscillator in response to the AFT error signal when the latter is above or below a reference voltage, the desired frequency being within the AFT capture range. However, when the AFT signal is absent, (i.e. is at the reference voltage), the control circuit 8 provides the control signal based 6 on the presence or absence of the synchronizing pulses, such that when the pulses are present, the local oscillator frequency is raised, but when the pulses are absent, the local oscillator frequency is lowered. Then, when the AFT signal is present, the local oscillator is again controlled thereby. AFT is terminated, and pulse generator 11 put into a low-speed mode, when it is detected 9, 10 that the AFT voltage has crossed its reference level. The invention is operative when the video signal in a selected channel (e.g. from a video recorder) has been interrupted, when the AFT will have caused locking on to the sound carrier of the adjacent lower (broadcast) channel. When the video signal resumes, its picture carrier frequency is now outside the AFT capture range, but by detecting its sync pulses the oscillator frequency is made to increase to permit recapture. The effective capture range is thus expanded. <IMAGE>

Title: Hardening shaped surfaces by plastic deformation
Inventor: KLUBOVICH VLADIMIR VLADIMIROVI
IPC: B21F35/00
Filed: 1982-06-03
Abstract: A helical coil 14 of substantially round cross-section is surface- hardened by means of deforming elements E,F arranged at opposite sides of the coil 14 for forced rotation in engagement with the surface of the material, while the coil is rotated about its longitudinal centreline and subjected to ultrasonic oscillations. The deforming elements E,F are rotated in opposite directions so as to form on the surface a regular microrelief in the form of an intersecting mesh-like pattern. By changing the ratio between the angular rotational velocities of the deforming elements E,F a microrelief of desired geometry can be attained. <IMAGE>
Patent GB-2103881-A (GB)
Title: Circuit-breaker
Inventor: LOGAN ROBERT JAMES
IPC: H01H1/64
Filed: 1982-06-30
Abstract: In a circuit-breaker a coil 22, which produces a magnetic field to rotate the arc, is connected between a terminal 18 and fixed contact 28 so that the field is available at contact separation. The coil 22 has an integral ring 50 carrying the fixed contact 28 which is engageable by a contact 52 forming part of a movable contact assembly 30. The assembly 30 is in electrical contact with a terminal assembly 20. The coil 22 has an associated ferro- magnetic body consisting of an external hollow cylinder 24 and a cylindrical core 26. As the coil 22 is permanently in series with the terminal assembly 18 and the contact 28, a field is produced by the coil 22 when the contacts 28, 52 are in engagement. Consequently, the arc is subjected to the field as soon as the arc forms between the contacts 28, 52 upon their separation. The arc extends between the contacts 28, 52 and its roots remain on and rotate on the contacts until the arc is extinguished. <IMAGE>
