Patent GB-2179290-A (GB)
Title: Locating metal inserts in rotational casting moulds
Inventor: TERRY REGINALD
IPC: B29C41/04
Filed: 1986-08-12
Abstract: In the rotational casting of hollow plastics articles, a metal insert (12) to be incorporated in the article (13) is located internally of a rotational mould tool (10) by apparatus comprising heat conductive fixing members (14). Each heat conductive fixing member has a stud (15) manufactured from brass or other metal having good thermal conductivity and of length sufficient for extending through the wall (11) of the mould tool into co-operation with the metal insert. An enlarged heat transfer surface (16) manufactured from brass, copper or similar metal having good thermal conductivity is attached to that end of the stud which is external of the mould tool, to provide an improved heat transfer from the exterior of the mould to the insert (12), and avoid defects which would otherwise arise from uneven distribution of the plastics (13) around the insert due to inadequate heat transfer into the insert. The enlarged surface (16) may be of a star shape (16), or of "U" shape (21, Figure 4). <IMAGE>

Title: Photographic developing process
Inventor: TJOOITINK CASEY
IPC: G03C7/407
Filed: 1988-06-20
Abstract: A photographic film developing process, that makes it possible for negatives that are part of the same filmstrip, regardless of contrast conditions existing at the time of exposure of these negatives, to be printed on one (normal) grade of paper only, comprises repeatedly interrupting the development by transferring the exposed material for a short immersion in water before returning it to the developer. This process slows development of the highlights whilst allowing more time for shadow detail to develop.

IPC: G01S3/801
Filed: 1988-09-29
Abstract: In a sonobuoy equipped with unfolding arms (2, figure 1) for carrying the hydrophones 7 of a sonar antenna, said hydrophones 7 are grouped in doublets 10.

Title: A dispenser, e.g. for cigarette packets
Inventor: BROUGHALL IAN MICHAEL
IPC: A47F1/08
Filed: 1991-05-29
Abstract: A body (22) defines a rearwardly sloping channel for stacks of packets (5). At the bottom there is a front opening for withdrawing the bottom packet of the front stack. The packet above is restrained from moving forwardly by a barrier (1) lightly urged against it, which permits it to drop to replace the removed packet. When the front stack is gone the barrier (1) moves rearwardly to contact the next stack. Suitably the barrier is a bar whose ends (4) travel in tracks defined in side walls of the body. These may be closed loops having a run which slopes rearwardly, said bar serving its restraining function while on this run; a return run sloping downwardly and forwardly from the rear of the restraining run to a location at or near the dispensing station; and a lift run. <IMAGE>

Patent GB-2255147-A (GB)
Title: Universal fluid line fitting
Inventor: HAMPEL ALEXANDER
IPC: F16L37/244
Filed: 1991-12-27
Abstract: A universal fluid line interlocking connector is disclosed (10, 20). The connector (10) may be fitted to an identical connector (20) so as to interconnect two fluid lines. The connector (10) does away with the requirements for both male and female components and provides a housing (10) having a locking lug (15) located at a maximum diameter position. The locking lug (15) has a claw position (18) located at its remote end. A seal (12) is provided radially internally of the locking lug (15). The seal (12) reacts to internal fluid pressure of the connector (10) to provide a tighter seal as pressure increases. One half of the connector (20) may be threadingly fastened to a fluid control device or outlet, or formed integrally with a fluid delivery means such as a spray nozzle for example, while the other half (10) is sealingly secured to an end of a fluid line (42) by means of a retaining claw (43) which is tightened onto the fluid line (42) by means of a retaining ring (44). The connectors (10, 20) are joined by inserting the locking lug (15) of each connector (10, 20) into the recess (19) of the other and rotating one of the connectors (10, 20). Each recess (19) provides an annular ramp with a crest such that positive locking occurs when the connectors are joined.
Patent GB-2254941-A (GB)
Title: Regulated power supply
Inventor: WILLIAMS BRIAN
IPC: H02P6/06
Filed: 1992-03-23
Abstract: The power supply of a brush less d.c. motor 1 has a trigger circuit 21 that determines the frequency of a ramp generator 27 which receives an output VS from an unregulated voltage supply 30. The amplitude of the output VR of the ramp generator 27 is dependent on the amplitude of voltage VS. A comparator 34 receives the ramp output VR at one input and a steady voltage VD at the other input. The comparator 34 produces a pulse output VC, with each pulse being initiated and terminated at transitions of the ramp signal and the steady signal so that the width of each pulse varies inversely with the unregulated voltage VS. The pulse output VC is supplied to the control input of the motor's commutation circuit 20. The circuit 20 switches the supply voltage VS to the coils of the motor 1 under control of the pulse signal VC so that its mean d.c. output VM is independent of variation in the supply voltage VS. <IMAGE>
Patent GB-2256766-A (GB)
Title: Reducing optical noise
Inventor: KEELER NORRIS R
IPC: G01S17/89
Filed: 1992-04-03
Abstract: An optical filter eliminates most optical noise (e.g., solar noise) in underwater LIDAR, imaging, bathymetry or communication systems. A reflected backscattered or emitted laser beam is split 102 into two beams of different polarizations filtered by identical FADOF filters 10, 10', and recombined 124 before being detected 128. Substantially all other wavelengths not corresponding to the transmitted wavelength are rejected by the FADOFs (Faraday anomalous dispersion optical filters) since the laser source is tuned to the FADOF pass-frequency. Each FADOF (Fig. 1) comprises a ceasium vapour (18) in a variable magnetic field which is heated to smooth out the hyperfine structure by means of the Doppler effect, preceded and succeeded by a polarizer (14, 34). Since the FADOFs are polarization-dependent, use of two in separately polarized channels reduces losses. <IMAGE>

Abstract: A roll container having at least two lateral walls (3), a rear wall and a base (1), includes a plurality of shelves (7) mounted on each lateral wall (3). Below the shelves (7) are respective width-reducers (9) which enable the container to maintain compact arrays of cartons (8) of differing standard sizes. The width-reducers (9) are displaceable between effective and ineffective conditions, perhaps by the shelves (7). The width-reducers (9) may be resiliently biassed by spring means towards their effective conditions or may themselves be resilient biassing means. Between the rear of the shelves (7) and the rear wall of the container are bridges in the form of thin steel strips. These strips either form rearward extensions of the shelves (7) themselves or are mounted retractably upon the rear wall. <IMAGE>

Title: Valved dispensing closure
Inventor: CAMPBELL ALEXANDER BRUCE
IPC: B65D47/20
Filed: 1992-10-15
Abstract: A two part fluid dispensing closure comprises an outer cap part 13 with a central opening and an inner part 12 fitting slidably within central aperture and being held normally at a stationary position with surface 16 in contact with surface 15 of the cap to block any egress of fluid: when fluid is to be dispensed, the dispensing pressure produced by squeezing container 11 causes the part 12 to be forced outwards in direction X, allowing egress of fluid via the gap then created. When fluid has been dispensed the inner casing is automatically drawn back into the outer casing at least as far as the stationary position. Preferably the part 12 is automatically drawn back to beyond the stationery position so that air is drawn into the dispenser with a consequent equilibration of pressure whereby the inner casing returns to the stationary point and is hold in place preventing further egress of fluid. The part 12 is held in position within the aperture by an array of equally angularly spaced flexible webs 17 (Figure 2) extending between the part 12 and a part 18 fixed between the container rim and the cap. The cap may snap fit on the container which may be positioned horizontally or in an inserted position and contain toothpaste, hand cream or shower gel. <IMAGE>
