Patent GB-2039160-A (GB)
Title: Sockets for receiving electrical devices
IPC: H05K7/10
Filed: 1979-01-03
Abstract: A socket for mounting to a printed circuit board (10) to receive a dual-in line integrated circuit (12) comprises a main body part (14) and a platform (40) which in the embodiment shown is slidably received by the part (14). The part (14) is fixed with respect to the board (10) by two straight rows of contact retaining devices (24) each soldered or otherwise secured to the board. Each device (24) comprises two resiliently deformable contacts (28, 30). To mount the integrated circuit (12), the platform (40) is raised to the position shown in Fig. 4 and the circuit (12) is seated thereon with contacts or pins (26) thereof each received in a respective one of the contact-retaining device (24), the pins (28, 30) of which are spaced to enable insertion of the pins (26). The integrated circuit (12) and the platform (40) are then pushed downwardly, whereupon cam surfaces (54) on the platform (40) push the pins (30) towards the pins (28) to clamp the pins (26) between the pins (28) and the pins (30). The integrated circuit (12) can be removed from the socket in a converse manner. With the construction described, the force required to insert and remove the integrated circuit (12) is minimal. Alternatively, the entire body of the socket (as opposed to just the platform (40)) is movable with respect to the contact-retaining devices (24) upon insertion and removal of the integrated circuit (12). <IMAGE>

Title: Improvements in or relating to couplings
IPC: F16L51/00
Filed: 1979-01-31
Abstract: A coupling is described (see Figure 1) having part spherical curved end sections (28, 30) which are received in cylindrical passages (16, 22) in two members (10, 20) which are to be joined together by the coupling to provide a continuous passage from one member to the other for the flow of fluid therebetween. The coupling includes at least one annular crease (32) which extends radially outwardly between the opposed end faces of the two members (10, 20) and axial misalignment vibration and distortion due to temperature changes during use are accommodated by means of the crease (32) which allows considerable relative axial and other movements between the two end sections (28, 30). In order to improve the seal between the coupling and the two members, the coupling may be subjected to axial compressive loading and to this end the extreme edges of the part spherical end sections are formed with 45 DEG  chamfered surfaces which engage complementary 45 DEG inclined surfaces (14, 24) in the members (10, 20) to be joined by the coupling. The coupling is preferably formed from seamless tubing such as cold drawn seamless steel tube. <IMAGE>

Title: A portable warning sign
IPC: E02F3/88
Filed: 1979-02-01
Abstract: A triangular road warning sign which can be carried e.g. by motor vehicles has a base tray c, e.g. of plastics, and a hinged lid l. The lid l has a reflective or fluorescent region on its surface, and carries lamps m. Batteries f to power the lamps are carried in the base. The lamps are automatically illuminated upon opening the lid as nib k releases switch h. The sign may be used as shown, with lid l held erect by stay d. Alternatively the lid hinges n may be uncoupled to allow the lid to be reversed (arrow q) and closed on to tray c without opening switch h, whereupon the sign comprises a closed illuminated triangular box with a hanging loop at one corner. In a modification the base tray is shaped for nesting in the well of the spare wheel of a vehicle. <IMAGE>

Title: Numerical control circuit for workpiece transfer equipment
IPC: G05B19/418
Filed: 1979-02-15
Abstract: A numerical control circuit is for workpiece transfer equipment equipped with at least one transport carriage on which controllable gripping elements are mounted, the transport carriage being movable horizontally and vertically by means of actuators numerically controlled by the control circuit. A CNC (computer numerical control) continuous path control system (10) is employed which is operated with a tolerance unit (20) the breadth of whose setting is adjusted, in use, in accordance with the generation of a preselectable position control pulse. The tolerance unit can thus be switched over from a narrow- tolerance setting to a broad-tolerance setting, and conversely, at the stages at which a change in tolerance is desirable, a narrow tolerance being desirable during the gripping and depositing of the workpieces and a broad tolerance being desirable during the actual transfer of the workpieces, e.g. in an automated press line. <IMAGE>

Title: A filter for gaseous fluids with a clogging indicator
IPC: B01D46/42
Filed: 1979-07-13
Abstract: A filter for gaseous fluids, e.g. air, incorporates an acoustical or visual clogging indicator.

Title: A Load Transducer
IPC: G01G3/00
Filed: 1979-10-01
Abstract: A load transducer includes a hollow body 10 and a movable control element 29 mounted in and extending through a wall 15 of the body 10 so that an external mechanical load can be applied thereto to move the same in one direction. Resilient means 41 urges the control element 29 in the opposite direction such that, in use, when an external mechanical load is applied thereto, the control element 29 is displaced by an amount dependent on the magnitude of the applied load. Coupled to the control element 29 is a variable capacitor 23 including a first electrode 28 supported by a hollow carrier member 26 in which a further carrier member 18 is mounted so that the carrier members 18, 26 are capable of relative sliding movement in a direction perpendicular to a pair of parallel mutually presented surfaces of the electrodes 22, 28. The carrier members 18, 26 are arranged so that movement of the control element 29 serves to impart said relative sliding movement to the carrier members, whereby the distance between said surfaces of and therefore the capacitance between the electrodes 22, 28 varies in accordance with the magnitude of the applied load. The electrodes are coupled in an oscillation circuit. <IMAGE>

Title: Musical toys
IPC: G09B15/04
Filed: 1979-10-19
Abstract: The invention relates to a toy, one embodiment of which is capable of being used as an educational toy for teaching music. A tape 10 has a first track passing beneath a window to indicate the notes to be played and a set of tracks with holes which serve to operate switching contacts 11 to 18. While the hole 108 permits contact to be made through the switching contact 18, a tape driving unit 3 is continuously driven and the holes 101 to 107 energize a music generator 6 so as to play a tune. This constitutes a teaching phase. At the end of the teaching phase, keys 21 to 27 must be operated in the correct sequence to allow the music generator to play the tune, the tape driving unit being arranged to stop if the incorrect key is operated. If an alternative embodiment of the invention, the correct tune is played when a pointer is manipulated to follow a predetermined track on the tape. <IMAGE>

IPC: C12Q1/00
Filed: 1981-05-21
Abstract: In assay methods involving converting a first substance in a sample to a second substance, oxidising the thus-formed second substance using an oxidase, and measuring the oxygen consumed or hydrogen peroxide generated during the oxidation, errors which occur due to the presence of amounts of the second substance in the original sample can be eliminated by contacting the sample, prior to the step involving the conversion of the first substance to the second substance, with an immobilised kinase in the presence of ATP to phosphorylate any second substance which may be present in the original sample and which would otherwise by oxidised by the oxidase. The method can be used for the assay of, for example, lactose or saccharose.
