Patent GB-2466954-A (GB)
Title: Variable width toaster
Inventor: DOWNIE DAVID
IPC: A47J37/08
Filed: 2009-01-15
Abstract: The invention relates to toasters intended for use especially, but not exclusively, in the domestic kitchen, and it relates in particular to such toasters having first and second toasting chambers (12, 18) of user-variable width to cope with foodstuffs of quite widely differing thickness, such as bread slices and bagels. The chambers have respective, individually energisable heaters, though they share a common partition wall that supports respective parts of the heaters for both. Operation of the heater for the second chamber is automatically inhibited when the first chamber is user-set, via use of lever 20which runs in slot 22, at or close to its maximum width. The lever 20 carries a mechanical actuator 26 which engages and depresses plunger 28a of a microswitch 28associated with the heating elements of second toasting chamber 18. This arrangement allows the second chamber to be used for toasting relatively thin items whilst the first chamber accommodates relatively thick items.

Title: Apparatus for automatically pivoting a hinged closure into closed position
Inventor: NEWAN HERBERT GEORGE ALBERT
IPC: B64D10/00
Filed: 1958-03-28
Abstract: 859,280. Respiratory helmets. RED WING Ltd. March 24, 1959 [March 28, 1958], No. 10109/58. Class 81 (2) [Also in' Groups VII and XXV] A helmet for use at high altitudes has a hinged vizor f which is automatically closed on a predetermined fall in pressure of the surrounding atmosphere by operating mechanism, a receptacle 8 for fluid under pressure and a device A, for permitting the fluid to operate the mechanism on said fall in pressure. The vizor f which is transparent is carried by a frame d which is hingedly connected through pivotal arms 1, 2 to an open front frame c of a head portion. The operating mechanism is housed in a casing 3 and a casing extension 4 which are mounted on one arm 1. A piston 5 in the casing extension is linked to a hinge pin 6 which is fixed to the other arm 2 and on which the first arm 1 pivots. Downward movement of the piston rotates the hinge pin and raises the other arm 2 to close the visor. The receptacle 8 is connected by a pipe 9 to a valve unit A which is connected to the casing extension above the piston by a pipe 7. An axial passage 12 in the valve unit A communicates with the pipe 9. A frangible diaphragm 14 e.g. aluminium, is supported by a plunger 17 at one end of the passage. A lever 18 holds the plunger in supporting position and is supported by a ball 20 restrained by a spring-urged plunger 21. The plunger 21 is connected to a barometric capsule which on expansion due to decompression of the atmosphere displaces the plunger 21 so that the ball moves into a recess, the lever 18 and the plunger 17 fall and the diaphragm 14 breaks. Pressure fluid then flows into the casing extension to move the piston 5 and bring about closure of the vizor. Alternatively, 'the piston may be formed with a rack 27, Fig. 8, which on downward movement rotates a pinion 26 on the hinge pin. Rotation of the pinion is transmitted by a spring 28 to a disc 25 fixed on the hinge pin which thus rotates to close the vizor. A projecting spring- urged pin 31 on the disc engages a notch in a lever 33 and prevents rotation of the disc before the pinion. A cam 34 projecting into the mechanism casing in the path of the pin briefly delays closure of the vizor after a small initial movement to give warning to the wearer. The rack and pinion may be replaced by a crank disc linked to the piston and rotatable on the hinge pin. An operating mechanism and a receptacle are provided on each side of the helmet, there being only one valve unit and the receptacles being interconnected.

Title: Improvements in or relating to apparatus for assisting vision under conditions of poor visibility
IPC: G02B23/12
Filed: 1963-03-14
Abstract: 996,555. Television. GENERAL ELECTRIC CO. Ltd., and E. R. THOMAS. Feb. 26, 1964 [March 14, 1963], No. 10245/63. Heading H4F. Apparatus for assisting vision under conditions of poor visibility, e.g. fog or mist, comprises a pulsed light source 1 and a photoelectronic image converter 2 having a control electrode or gate to which is fed a control signal from a control signal generator 3 so that the converter does not produce a visible image in response to the light received by it during the period and immediately following the period when each pulse of light is emitted from the source, the arrangement being such that only light that is reflected back from beyond a critical distance from the apparatus causes the converter to produce an image. Light source 1 may be a current stimulated gallium arsenide diode in a lasing or a non-lasing mode, a light stimulated laser or a gas laser, which emits regularly recurrent flashes of light 4, Fig. 2, of short duration t e.g. of a few nanoseconds, at a rate of once every microsecond, the light being in the visible or near-visible part of the spectrum. Curve (b), Fig. 2, shows the waveform of the control signal pulses 5 supplied by generator 3, each pulse being of duration T nanoseconds spaced x nanoseconds apart, the frequencies of flashes 4 and pulses 5 being the same. As only light received by intensifier 2 during intervals between pulses 5 produces an image, only the light reflected back from objects beyond a certain distance l from the apparatus will produce images. Thus object B produces an image but object A doesn't, thus avoiding the back scatter of light from near fog particles. The fluorescent material on the screen of the intensifier 2 preferably has a short response time and a relatively slow decay.

IPC: F16C1/02
Filed: 1929-04-03
Abstract: 327,566. A.C. Spark Plug Co. Feb. 6, 1929, [Convention date]. Flexible shafts.-Flexible shafting for driving speedometers, dental drills, &c. consists of a central core wire 4 of phosphor bronze surrounded by a layer 6 of phosphor bronze wire wound thereon under tension so as to compress the engaging- surfaces. Upon the layer 6 are tightly wound one or more layers 8, 10 of hard steel wire, for example 0.43 carbon wire. The coefficient of friction between the phosphor bronze and steel is low, so that wear therebetween is small during bending of the shafting. Lastly, if desired, one or more layers 12 of soft steel, for example 0.10 carbon wire, are similarly added and prevent unravelling of the shaft when the shafting is cut. After each layer is wound, it is massaged between withdrawing-rollers and in a shaft-straightening operation so that the layers are each stretched and adjacent layers are slightly separated to provide lubricating space therebetween.
