Title: Warning device
IPC: B60Q9/00
Filed: 1982-03-24
Abstract: A device warns that a first electric circuit is energised after a second electric circuit has been de-energised e.g. that vehicle lights have been left on after the ignition has been switched off. The ignition and lighting circuits include respective ignition and ON-OFF switches S1 and S2 with both switches closed relays, 1,2,4 operate to move their contacts from the position shown. On operating the ignition switch S1 to switch off the ignition, the relay 1 is de-energised and relay 7 is energised to energise after a delay provided by a device 10, warning means 9, 12 to indicate that the lights are switched on. If it is desired to leave the lights on the switch 52 is opened to de-energise relay 2 then closed again. An alternative circuit using transition and NAND gates is described. <IMAGE>
Patent GB-2096174-A (GB)
Title: Blood fractionation
IPC: A61K35/16
Filed: 1982-03-25
Abstract: The extraction of Factor VIII, the antihaemophilic factor in blood, is difficult due to its instability and the presence of impurities. An initial Factor VIII containing aqueous solution such as blood plasma is purified by subjecting a FactorVIII containing aqueous migrant solution to continuous flow electrophoresis wherein flow takes place in an annular separation chamber and is stabilised by means of an angular velocity gradient; and collecting a separated Factor VIII component.In order to separate the Factor VIII from albumin and fibrinogen, whilst obtaining good recoveries of FactorVIII (e.g. -60%), the migrant solution is prepared by precipitating FactorVIII from the initial solution using an organic liquid such as ethanol, and removing and redissolving the precipitate in an aqueous medium and adjusting the pH to be within the range of 7.5 to 8.6, preferably 8.3 to 8.6.

Patent GB-2127185-A (GB)
Title: Electrical signal generator
Inventor: PAPWORTH DEREK FRASER
IPC: H03L5/00
Filed: 1982-09-22
Abstract: The circuit produces an output at a terminal 60 having an accurately controlled RMS value, e.g. for testing voltmeters. An oscillator 10 produces an alternating output, which need not have a particularly pure waveform, whose RMS value is compared 42 with an RMS reference signal on a line 68. The comparator 42 may incorporate a thermocouple for producing a d.c. output dependent on the RMS value of the oscillator output, in which case the signal on line 68 is a d.c. reference. Any RMS error is fed back via line 70 to control the amplitude of the output of oscillator buffer 18 via level control 72. Attenuators 64 vary the fixed-RMS value on line 62 to produce the variable output signal at terminal 60. A separate oscillator 82 is selectable by a switch 38, instead of oscillator 10, so as to produce a variable crest factor output, again controlled as to its RMS level via line 70. The reference output can be selected by switches 80 and 40 to produce a + or - d.c. output instead of an alternating output. <IMAGE>

Title: Moulding fired clay or ceramic articles
Inventor: GUARD JOHN
IPC: B28B7/00
Filed: 1982-10-18
Abstract: A drawing is made of a pattern which it is desired to form into an impression in a clay or ceramic article, e.g. a brick or tile. A relatively thick printing plate has the pattern formed in its surface, by an optical method, eg etching or laser cutting, to a depth of 1 mm to 5mm. The plate is then used as a wall portion of a mould in which the clay or ceramic material is pressed. The resultant pressed body is then removed from the mould and fired. A very high degree of detail can be formed on the clay or ceramic article in this way.

Title: Collapsible support mechanism and articles incorporating same
Inventor: RYDER-SMITH SIMON CHRISTOPHER
IPC: A45F3/24
Filed: 1983-04-05
Abstract: A collapsible support mechanism which can, for example, be incorporated in a child's high chair, the mechanism comprising first, second and third arms (1-3) each pivoted at one end thereof one to another and struts (6,7) pivotably mounted between the first and second arms and the third and second arms, respectively. The pivotal mounting of the struts to the arm (2) is achieved by a slidable part (8) such that, in one position of the part (8) on the second arm (2), the mechanism is in a collapsed condition, whereby all of the arms lie substantially parallel and adjacent to one another and in another position of the slidable part (8) the arms are splayed out so that the first and third arms (1,3) can form a supporting base and the second arm (2) can form a member by which an article, such as a high chair seat, may be supported. In one form of the mechanism, the second arm leans forwardly over the first and third arms and, in another form, the second arm leans rearwardly. In this latter form, one mechanism can be joined to another to form, for example, a hammock frame. The mechanism may also be used to support a child's swing or an article, such as a ball or basket, forming part of a game. If the mechanism is inverted so that each of the arms (1-3) become legs, it may be used as an easel or a tent frame. <IMAGE>

Title: Pilfer-proof closure
Inventor: HERBERT JAMES FREDERICK
IPC: B65D41/34
Filed: 1983-10-17
Abstract: A metal pilferproof closure for a container having an externally screw-threaded neck comprises a top 11, skirt 12 and pilferproof band 13. The boundary between band 13 and skirt 12 is defined by a continuous peripheral score line on the internal surface of the closure, and further score lines 15 extend from the lower edge of band 13 to said peripheral score line. The skirt is devoid of any protective bead or ring of knurling immediately above said peripheral score line. The lower extremity of band 13 is turned inward during application of the closure so as to lie against a shoulder which is inclined outward at an angle of 20 DEG  to the horizontal. The position of said peripheral score line is such that it is spaced radially away from the external surface of the container. When the closure is unscrewed the band 13 fractures along some or all of the score lines 15 and the peripheral score line forms a hinge axis about which the segments defined by score lines 15 can pivot outward. <IMAGE>

Title: Dual flush cistern conversion
Inventor: CUMMINGS STEPHEN
IPC: E03D1/14
Filed: 1983-11-15
Abstract: In order to convert a single- flush valve-discharge cistern to dual flush without alteration to the cistern body, an open-topped box 5 is inserted in the cistern to form a partial-flush compartment around the discharge valve, the box having a base aperture 6 which accommodates the vertically- movable discharge valve and a side opening closed by a hinged flap 9 linked to the cistern flushing mechanism. Upon flushing of the cistern a full flush occurs when the flap 9 is open but when said flap is in its closed position a reduced or partial flush occurs. The specification discloses (Figs. 2-6) a valve discharge cistern incorporating the box of Fig. 1 and provided with a first full-flush push- button mechanism which operates only the flushing valve and leaves the opening free; and a second partial flush push-button mechanism which operates the flushing valve and closes the flap across the opening. <IMAGE>

Abstract: A video or rf switch includes a common port (538) and a plurality of second ports (A,B,C) to which the common port may be coupled by a plurality of switch sections in a single pole, multiple throw configuration. Each switch section includes a diode (514,522,612) coupled to the common port and a source of voltage (523,530,617) for energizing the diode. Conduction through the diode forward-biases it and causes current flow through a common biasing resistor (536).
