Patent GB-2272843-A (GB)
Title: Filter elements
Inventor: GRIMES MICHAEL ERNEST
IPC: B01D39/20
Filed: 1993-11-09
Abstract: A tubular metal filter sleeve 34 is placed on a polymeric end cap 31 and heated by induction coil 24 so that it melts its way into the cap and bonds thereto. The degree of penetration is limited by projections 39 on a split ring 37 clamped round the sleeve. Argon or an argon-hydrogen reducing mixture fed through passage 27 prevents the heated metal from oxidising. The sleeve 34 may be stainless steel sintered powder or fibres or sintered mesh. The end cap 31 may be polyester, polypropylene or polyetheretherketone. A somewhat similar apparatus (Fig. 3) enables the metal sleeve to be separated from the end cap after use, so that a new end cap can be fitted. The sleeve may be pleated or not. <IMAGE>

Title: Tag circuit arrangement
Inventor: FORSTER IAN JAMES
IPC: G01S13/76
Filed: 1994-11-30
Abstract: A circuit arrangement, particularly for use with a transponder, comprises a transistor (1) configured to detect an amplitude modulated signal upon operation within the non-linear relatively low gain region (A) of the transistor's current voltage characteristic. The transistor is also configured by means of a feedback arrangement (10, C1) upon operation within a linear relatively higher current and gain region (B) of the characteristic to reflect the signal with an increased amplitude, the transistor acting as a negative resistance. The change in operating point is effected by switching the biasing network  alpha  (6, 7) values. Operation of the switch (52) while in the reflection mode is also used to modulate the reflected signal. Modulation (14) of the power supply to the transistor with a periodic waveform produces a single side band reflected signal. <IMAGE>

Title: Method of use of acceleration responsive device
Inventor: BUTLER JOSEPH H
IPC: G01P15/03
Filed: 1995-07-18
Abstract: An acceleration responsive device includes a support which supports a rod 46 between two spaced portions of the support and a weighted disc 48 is mounted for movement on the rod and is held by a spring 128 at one end of the rod 46. An indicator 50 is also mounted for movement on the rod 46 adjacent disc 48. A tube 62 is coupled to the support to facilitate swinging movement of the device where, owing to the acceleration thereof, disc 48 is moved along rod 46 and pushes indicator 50 along the rod. When the swinging movement ceases, disc 48 is returned to the one end of rod 46 and indicator 50 remains at the position to which it was moved. A scale reading of a decal 89 adjacent the moved indicator 50 provides a indication of the acceleration attained during the swinging of device. This reading is applied to a graph of stiffness against acceleration to assist the user of the device in the selection of golf clubs having a shaft stiffness which is most appropriate. <IMAGE>

Title: Improved golf club heads and method of making them
Inventor: REYES HERBERT
IPC: A63B53/04
Filed: 1998-10-19
Abstract: Golf club heads of iron, wood and putter type, and methods of manufacturing such golf club heads, involve use of one or more layers of a loaded film (20) to define in part the overall weight, center of gravity, and inertial characteristics of the golf club head, without significantly affecting the structural characteristics of the golf club head. A set of plies (14,16,18) of pre-preg composite fiber sheet and one or more layers of loaded film (20) are applied in a predetermined manner to a forming mold to make a preform. The preform is removed from the forming mold. One or more additional layers of densified loaded film may be applied to the preform, and the preform placed in a curing mold. In the case of hollow, e.g. wood type club heads, a bladder may be introduced into a hollow core of the preform, the bladder may be then inflated, and the mold heated for a predetermined period of time. Alternatively, a dry reinforcement preform may be made on the forming mold from a set of plies of composite fiber and loaded film. Prior to heating the mold, resin is injected into the mold, providing a binding material for the composite fiber and loaded film comprising the preform.
