Title: Flange cutter
Inventor: KING CECIL ARTHUR JOHN
IPC: A61F5/445
Filed: 1990-10-19
Abstract: A flange cutter for precise cutting of circular holes in laminar articles, in particular stoma adhesive seals, comprises a base member 10 for supporting the laminar article and having an upstanding cylindrical portion 16 which extends through the hole (2, Fig 1) in the seal and which engages a separable cutting device 19 comprising a cutter support 18. The cutter support carries an offset blade holder which has a foot 31 formed with a slot 32 sized to allow passage therethrough of a blade 25. The foot 31 is retractably connected to the blade holder via a compression spring 33. Downward travel of the foot 31 in association with the blade holder is limited by the flange, causing compression of the spring on further downward travel of the blade holder so that the blade projects from the slot and penetrates the flange. Relative rotation between the flange and the blade, preferably by rotating the knob 38, can achieve a circular cut. The radius of the circle is variable by adjustment of the arms 21, 22. An alternative construction with an elongate narrow base (110, Fig 9) can be used on a stoma seal incorporated in a bag (55 Fig 5) by inserting the base through the initial hole (56) in the seal. <IMAGE>

Title: Respirator filters
Inventor: RHYMER MICHAEL JOHN
IPC: B01D53/04
Filed: 1991-03-26
Abstract: A method of making a respirator filter, which includes charcoal granules 12 confined between grid assemblies 10 and 11 within a filter canister housing 8, includes the step of making at least one of the grid assemblies, which comprises an apertured metal grille 2, a support medium (3, Fig. 1) for preventing material passing through the grille 2, and a dust filter (4, Fig. 1), by forming a lip 5 of deformable resilient material extending outwardly beyond the circumference of the assembly so that the lip 5 holds the grille 2, the support medium and the filter as a single assembly. When used in a lower grid assembly, the lip 5 prevents charcoal dust escaping into gas breathed through the canister, and, when used on both upper and lower grid assemblies the lip 5 ensures that no breathing gas passing through the filter canister can bypass the bed of charcoal granules. Bead 14 of adhesive holds lip 5 against the wall of housing 8. <IMAGE>

Title: Method for determining the dynamic safety margin of motor vehicles
Inventor: WEINZERL ALFRED
IPC: B60W30/02
Filed: 1993-01-15
Abstract: A motor vehicle is equipped with a steering angle sensor 7, longitudinal and transverse acceleration sensors 8, and an ABS device 9 supplying angular wheel velocity signals. To determine the dynamic safety margin, an adhesion value in the transverse direction is first determined in the control device 6 from transverse acceleration and steering angle, and an adhesion value in the longitudinal direction from angular wheel acceleration and longitudinal acceleration. The maximum achievable longitudinal and transverse accelerations are then determined from the two values by multiplying by vehicle- specific coefficients. A limit curve is then formed therefrom, and the transverse and longitudinal accelerations are compared with the limit curve to determine the dynamic safety margin. Warning indicators 20, 21 are energised if a limit is approached or exceeded. <IMAGE>

Title: Protection arrangement for a CRT display scan circuit
Inventor: JACKSON FREDERICK SAMUEL
IPC: H04N3/27
Filed: 1993-06-15
Abstract: A CRT display scan circuit 100 having a switch transistor 101 with multiple frequency operation, has a supply voltage Vs which changes with changing scan frequency. A decrease in scan frequency at a rate faster than the supply voltage can decrease may cause overcurrent failure of the switching element 101. In a protection circuit, Fig. 2, a sawtooth voltage waveform representing the current flowing in the switching device 101 is synthesized at 208 based on the supply voltage Vs and the conduction time of the switching element 101, using a storage capacitor 339, current sink 200 and zero crossing detector 210. If the sawtooth voltage exceeds a reference voltage 214, a comparator 220 indicates overcurrent in the transistor 101 and terminates drive signal 108 in the current cycle or until the supply voltage has decreased. <IMAGE>

Title: Monitoring link quality in a TDMA radio communication system during silent periods
Inventor: SATO OSAMU
IPC: H04B17/382
Filed: 1995-06-06
Abstract: When a detector 44 senses a silent period due to the absence of speech signals from a microphone 38, a mobile station 30 is caused to transmit back to the base station the last sync signal which was received from the base station and stored in a memory 43 of the mobile, whereby the base station can still monitor link quality during silent periods. During a silent period, each TDMA transmission time slot from the mobile includes the returned sync signal as a second sync signal, preceded by a first sync signal added by the mobile (Fig. 1c). The base station judges link quality from both the bit error rate of the returned, second sync signal and from the field intensity or bit error rate of the first sync signal. Depending on the judged link quality, the base station may change the allocated radio channel or may cause the radio link to be cut off. <IMAGE>
