Title: Trenchless pipeline installation method with pilot hole corrective alignment
Inventor: COSS TIMOTHY R
IPC: E21B7/20
Filed: 1995-02-22
Abstract: A corrective trenchless pipeline installation method basically includes the operational steps of forming an initial pilot hole (10) underground in earthen matter between a pair of spaced entry and exit pits (18, 20) formed in the earthen matter and reforming the initial pilot hole (10) into a trenchless corrected pilot hole (12). The initial pilot hole (10) is formed along a first line extending from an entry point (19) to an actual exit point (21) wherein the first line of the initial pilot hole (10) is substantially irregular compared to a desired second line of the trenchless corrected pilot hole (12) which is substantially straight and extends from substantially the same entry point (19) to a desired exit point (23) displaced laterally from the actual exit point (21). The corrected pilot hole (12) extends along the desired second line. The corrective installation method further includes the operative steps of reaming the corrected pilot hole (12) to provide an expanded corrected pilot hole and pulling a pipeline (16) through the expanded corrected pilot hole.

Title: A cylinder block structure for an internal combustion engine
Inventor: HUTCHINS WILLIAM RICHARD
IPC: F02F7/00
Filed: 1995-12-19
Abstract: An internal combustion engine (20) comprises a cylinder block (22), a cylinder head (24), and a plurality of fasteners (47) holding the head onto the block. The block comprises a single structure having walls (34) defining four cylinder bores (36) arranged in a line for receiving pistons, longitudinal support sections (60, 61) extending along the block one on either side of the line of bores and transverse support sections (74) joined to the longitudinal support sections and extending substantially tangentially to the bores. The fasteners (47) are arranged to engage with the block (22) such that a substantial part of the load exerted on the top of the walls (36) of the bores is transmitted to the fasteners via the support sections. This prevents forces from being transmitted radially into the cylinder walls (36) and thereby reduces bore distortion.

Title: Snap fitted bottom stop for zip fastener
Inventor: FAILING NORBERT
IPC: A44B19/38
Filed: 1997-07-25
Abstract: A bottom stop assembly for a separable parts zip fastener comprising a box 14 having side walls 26, 28 joined by a web 30 and formed with flanges 40, 44. Flanges 40, 44, web 30 and side walls 26, 28 define two channels 47, 43. A bottom pin 8 is attached to a stringer and received in one of the channels 47 and a bottom end stop 16 is attached to another stringer and received in the other channel 42. Flanges 44 may be formed with nibs 48 that project into channel 47 to urge the bottom pin 8 against the web 30. Engaging surfaces 54, 56 formed by a cut out 50 in the bottom pin 8 engage with engaging surfaces 32, 34 on the web 30 to limit axial movement of the pin 8 in the box 14. A bulge 60 may be formed on the lower end of the bottom pin 8 to bear against the nibs 48. Flanges 40, 44 may become thicker towards the bottom of channel 47 in order to wedge the bottom pin 8 against the web 30. With this arrangement box 14 can be snap-fitted to the bottom pin 8 after the stringers have been sewn in place, therefore the box 14 does not impede the sewing process.

Title: A semiconductor memory device with a parallel bit test circuit built therein
Inventor: KIM NAM-JONG
IPC: G11C11/401
Filed: 1999-03-04
Abstract: A semiconductor memory device 1 comprises a memory cell array 100, and input/output line pairs connected to the memory cell array 100 and divided into a plurality of groups. In normal mode means 140 reads out data from the memory cell array 100 through each of the input/output line pairs, and output means 160 outputs the data read out by the read means 140 into each of input/output pads provided in the device. Furthermore, the device comprises parallel bit test means 170 which compares two input data with expected results and is connected to one input/output pad. The parallel bit test means 170, when at least two groups of the input/output line pairs are selected during the parallel bit test mode, receives data corresponding to the two selected groups of the input/output line pairs from the read means 140. Then during a single cycle of the externally applied clock, sequentially outputs two test data signals to the input/output pad in response to first and second internal clock signals produced by an internal clock generating means 130 from external clock XCLK. The time required to test all data stored in the memory cell array can be reduced by half, so that the test cost can be reduced.

Title: Energy absorbing arrangements
Inventor: TOURNIER PASCAL GERARD
IPC: B60R19/34
Filed: 1999-03-26
Abstract: An energy absorbing arrangement (10) comprises a conical tube (16), made of thermoplastic material and having an integral end face (18) carrying a bracket (19) for supporting a vehicle bumper. Its other end has a flange (20) with holes for receiving fixtures (24) to attach it to the front of the vehicle. In response to an impact on the bumper, energy is absorbed by micro-rupture of the material of the tube (16). At the same time, a tongue (26) is forced through a hole (32) in a plate (12) on or forming part of the front (or rear) of the vehicle, and claws (28) prevent reverse movement of the tongue (26). The bumper therefore remains supported even after micro-rupture of the tube (16).

Title: Reflector circuit with reflection amplifying means
Inventor: FORSTER IAN JAMES
IPC: G01S7/38
Filed: 1999-04-23
Abstract: A reflector circuit 1, particularly for use in a pseudo passive transponder (PPT) tag or as radar chaff, receives illuminating radiation 4 and responds by radiating corresponding output radiation 6 of increased magnitude relative to the received radiation 4. The circuit 1 comprises antenna means 2 for receiving and re-radiating radiation and processing means for amplifying and storing for a period of time, a portion of the signal received from the antenna 2 for use as the output radiation 6. The processing means incorporates a reflection amplifier 10 to provide amplification and the storage is preferably provided by a delay line 8. The reflection amplifier 10 is capable of providing high gains approaching +30dB at relatively low current consumption, for example tens of micro amperes. The processing means may further provide frequency selective amplification such that amplification is reduced for components of the illuminating radiation 4 that are likely to cause overload, saturation or distortion in the circuit. Preferably a magnetostatic wave delay line (MWDL) is used for storage and to provide the frequency selective response although other delay lines may be used e.g. optical, SAW, BAW. Switches may be incorporated and are operable to counteract spontaneous oscillation within the circuit.

Patent GB-2351857-A (GB)
Title: Lamp dimmer
Inventor: DAVIES KEVIN
IPC: H05B37/02
Filed: 1999-07-01
Abstract: A lamp dimmer has a controller (24, Fig.2) with a brightness selection cycle during which a varying output signal is provided indicative of varying brightness, and a memory (26) for storing a value representing a selected brightness at the end of the selection cycle. An audible signal of varying tone or pulse repetition rate may be employed as the varying output signal, but preferably a ramped light output is provided as this signal. The memory (26) stores the selected brightness in response to the power input to the dimmer being switched off (at t<SB>2</SB>, Fig.4) when the lamp reaches the desired brightness as the light output is ramped up during the selection cycle. The lamp is then operated at the selected level when the power input is switched on again (at t<SB>3</SB>). If the lamp is then left on for longer than a threshold period (t<SB>threshold</SB>), the dimmer is reset, so that when the power is turned off and then on again it starts with the brightness selection cycle again. If, following the selection cycle, the power is turned on (at t<SB>3</SB>, Fig.5) and then turned off (at t<SB>4</SB>, Fig.5) after a time (t<SB>4</SB> - t<SB>3</SB>) less than the threshold period, a security mode SM is set, and the security mode is implemented the next time that the power is turned on (at t<SB>5</SB>). The lamp may be flashed a number of times to indicate that the security mode has been set. During the security mode the lamp may be turned on and off at random intervals during times of darkness, sensed by an ambient light sensor (11, Fig.1). The dimmer may be incorporated into an adapter (10, Fig.1) which fits between a lamp socket (14) and a lamp (12), or the dimmer may be built into the socket or provided in the lamp.
