Title: Chromatography column
Inventor: SIBBALD ALASTAIR
IPC: G01N30/60
Filed: 1993-02-24
Abstract: A chromatography column assembly comprises a pair of transparent glass plates (1, 2) positioned so that a major surface of each (4, 5) faces, is parallel to, and is spaced from the other. An adhesive (3) is provided between the plates to secure each to the other. This adhesive is patterned by screen printing to define a channel (6) between, and running parallel to, the major surfaces of the plates. The channel has an inlet and an outlet orifice drilled through the plates for the introduction and exhaust of a sample fluid.

Patent GB-2265300-A (GB)
Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/34
Filed: 1993-03-24
Abstract: The retractor comprises a reel shaft which is locked when an emergency occurs. During an emergency a lock gear 13 rotates in a direction B relative to a reel shaft 4, and a projecting shaft 19d is thereby moved by the action of a first cam hole 13i, causing a main pawl 19 at one end of the reel to pivot in the direction B. Thus, teeth 20a which are to be engaged with first and second pawl portions 19b and 19c are decided. At this time, a backup pawl 22 at the other end of the reel does not pivot because a projecting shaft 21c merely moves along a hole 13m. When the lock gear 13 further moves in the direction B relative to the reel shaft 4, the first and second paw portions 19b and 19c begin to engage with the teeth 20a, and the projecting shaft 21c moves along a radial hole 13k. Thus, the backup pawl 22 pivots in the direction B, and a tooth 2f which is to be engaged with the backup pawl 22 is decided. When the lock gear 13 further rotates in the direction B relative to the reel shaft 4, the first and second pawl portions 19b and 19c completely engage with the teeth 20a at the same time as the backup pawl 22 completely engages with the tooth 2f. In an alternative arrangement both pawls are supported by the frame and the teeth are formed on the end discs of the reel (Figs. 43 to 51). In a further embodiment the main pawl engages before the backup pawl and the final movement of both pawls is effected by steep slopes on the cooperating teeth (Figs. 16 to 42). <IMAGE>

Patent GB-2287828-A (GB)
Title: Semiconductor laser device and fabricating method therefor
Inventor: YOSHIDA YASUAKI
IPC: H01S5/00
Filed: 1995-03-24
Abstract: A semiconductor laser device comprises semiconductor layers including an active layer 3 sandwiched by cladding layers 2, 4, and a current injecting means for regulating a region of the active layer to which a current is injected. A light confinement coefficient for confining light in the vertical direction of the current injection region 10 to which current is injected is smaller than a light confinement coefficient for confining light in the vertical direction of the saturable absorption region 11 to which no current is injected. Therefore, the function of the saturable absorption region (11) is enhanced and the pulsation oscillation can be preserved up to a high light output. This may be achieved by a difference in thickness (t1, t2) of the active layer, a difference in the number of thickness of the wall layer of a MQW structure forming the active layer (Fig. 2), or a difference in differential gain between the current injection region and the absorption region (Fig. 10). <IMAGE>

Title: Decoding of a signal
Inventor: FINES PANAGIOTIS
IPC: H04L27/14
Filed: 1995-04-11
Abstract: Data is transmitted in a signal comprising a data signal at a frequency within a range of discrete frequency tones representing a predetermined range of digital values, and a pilot signal. The signal is received by a circuit comprising means (44 to 54) which transforms the received signal into a set of frequency samples of the pilot signal and a set of frequency samples of the data signal. The samples are input to a correlator (58) which correlates the set of frequency samples of the pilot signal with the set of frequency samples of the data signal at each of the discrete frequency tones in order to identify the discrete frequency tone to which the frequency of the data signal corresponds. In this way, the digital value represented by the data signal can be identified. The circuit is suitable for use in a radio pager for receiving data signal transmissions from a distant source which may be transmitted from a satellite.
Patent GB-2291095-A (GB)
Title: Curtain-sided vehicle
Inventor: BERRIDGE PATRICK LEONARD
IPC: B60J5/06
Filed: 1995-07-11
Abstract: A curtain 2 is suspended by hangers 42 which move along a generally upwardly directed supporting surface 27, the track 10. Each hanger 42 carries two or more rollers spaced, longitudinally of the track and rotating about a respective axis extending generally transversely of the track. The efficiency of the apparatus is largely unaffected by tilting of the hangers due to movement of the lower part of the curtain in a direction transverse of its principal movement during drawing. The track can have a retention formation which prevents removal of the rollers from the supporting surface by transverse movement. <IMAGE>

Title: Retraction system for a latching mechanism of a tool
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B23/03
Filed: 1996-08-22
Abstract: A retraction system is described for allowing disengagement of retrieval latch dogs (114) of a down hole running tool (14) from a bit locking sleeve (18). The locking sleeve (18) is slidably retained within a drive sub (12) and includes a pair of slots (66) which are engaged by the retrieval latch dogs (114) when the tool (14) is used to retrieve bit segments (16) from the drive sub (12). The retraction system includes a sleeve (76) which is slidably mounted on a main body (74) of the tool (14) and spring (174) which is biased to push the sleeve (76) over the retrieval latch dogs (114). The sleeve (76) has a pair of diametrically opposed slots (235) through which the retrieval latch dogs can extend for contacting the inner surface (28) of the drive sub (12). The retraction system also includes a length (44) of the inner surface of the drive sub (12) which is made of progressively reducing diameter in the direction of retraction of the tool (14) from the drive sub (12). The upper end of each slot (235) is provided with a bevel (236) for directing the retrieval latch dogs (114) in the inward direction. To withdraw the tool (14) from the drive sub (12), the retrieval latch dogs (114) are disengaged from the bit locking sleeve (18) by the combined action of the shape of surface portion (44) which acts to push the retrieval latch dogs (114) inwardly, together with the force of spring (174) and the bevelled surfaces (236) which act to push the sleeve (74) over the retrieval latch dogs (114) thereby disengaging it from the bit locking sleeve (18).
