Title: Improvements in or relating to duplicating machines
Inventor: TOMLIN EDWARD ALBERT
IPC: B65H29/56
Filed: 1953-09-04
Abstract: 733,398. Sheet-delivery apparatus. GESTETNER, Ltd. April 27, 1954 [Sept. 4, 1953], No. 24529/53. Class 100 (1). A duplicating machine comprises a rotatably driven stencil-carrying cylinder, a pressure roller to apply the copies to the cylinder and blades for stripping the copies from the cylinder, the pressure roller and the blades being movable towards and away from the cylinder, and the blades being so moved by a mechanism separate from that which moves the pressure roller. Sheets are fed between the lower cylinder 12, Figs. 2 and 5, of a stencil duplicating machine and an impression roller 13, and are stripped from the cylinder by two blades 28, whence they are passed to guides 23 and thence to a stack. In order to permit the free passing of the means for attaching the stencil and screen to the travelling band 14, the roller 13 and the stripper blades 28 are oscillated towards and away from the cylinder 12. The blades are secured to blocks 29 which are adjustably secured by means of nuts 30 along a bar 25 so that the blades can be set to engage the parts of the sheets having least ink. The bar 25 is mounted at one end in a spring bearing to facilitate removal. The machine is driven by a handle 16 on a shaft 17, and the latter carries a cam 36 which acts on a lever 38 to oscillate a rocking member 34 pivoted at 35. A slot 33 in the member 34 engages a pin 32 on a lever 31 secured to the bar 25, so that the blades 28 are oscillated. The blades 28, the ends of which are bevelled to be tangential to the cylinder, are not required to touch the cylinder, and the size of the gap is adjusted by means of a cam 55 engaging the pin 32, the cam being set so as to correctly limit the upward stroke of the blades. The guides 23 are part of a member 20 which is hooked on to a bar 19 and secured by a spring clip 21 engaging a spindle 22. The top edge 24 of the guides is central of the sheets and higher than the blades 28, so that the sheets are bowed in the centre to impart a certain rigidity thereto.

Title: Improvements in polycaronates
IPC: C08G64/18
Filed: 1960-07-18
Abstract: A block copolycarbonate consists essentially of blocks comprising recurring units of formula <FORM:0938124/IV(a)/1> and blocks consisting of recurring units of formula <FORM:0938124/IV(a)/2> where R is a naphthyl group attached in either the 1- or 2-position and which may be substituted in the remaining 2- or 1-position with chlorine or fluorine.  Preferably, the number of units in any block is 3-50 and the units of the former formula are present in about 40-85 mole per cent of the block copolymer.  The copolycarbonates may be made by first making two homopolymers by reacting phosgene with 2,2-bis(3,5-dichloro-4-hydroxyphenyl) propane or a bis(4-hydroxyphenyl) naphthyl methane on which the latter formula is based, the reaction being effected in the presence of methylene chloride and aqueous caustic soda; then reacting the two homopolymers in the presence of tri-n-butylamine, next acidifying the reaction mixture with acetic acid to stop the copolymerization, and finally washing the resulting viscous dope and precipitating the copolymer from solution by pouring it into methanol.  The copolymers may be made into films, e.g. by casting them from methylene chloride solution, which are useful in the manufacture of photographic film bases, packing materials, adhesive tape bases, kinescope recording tapes and condenser dielectrics.

Abstract: 1,033,925. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 21, 1963 [July 2, 1962], No. 25285/62. Heading B7K. [Also in Division H2] A vehicle is associated with track 14 upon which it is supported by a cushion of pressurized air 12, driving motor 1 being of the linear type co-operating with continuous armature 13. A pole-changing unit 3 for the motor 1 is automatically controlled by a velocity detector 5 responsive to the speed of the vehicle. Upon failure of supply 2, the unit 3 sets the motor 1 for a synchronous speed below that at which the vehicle is travelling, the field of the motor being maintained by exciter 9 driven by prime mover 10. The motor 1 thereupon acts as a generator for supplying compressor motor 6 to maintain the supporting cushion for the vehicle. The unit 3 provides pole-changes as the motor decelerates to maintain re-generation until the speed has decreased to a safe value for use of wheeled or skid supports. In another arrangement, the pole-number of the motor 1 remains unchanged in the condition of power failure, the frequency of exciter 9 being reduced as the vehicle decelerates. The exciter 9 may be replaced by a reactive device which is automatically brought into use upon failure of the power supply, or by a battery-operated oscillator.

Title: An improved electrical cut-out
IPC: H01H87/00
Filed: 1921-09-26
Abstract: 189,284. Illingworth, W. H. Sept. 26, 1921. Mercury cut-outs in which the circuit is broken on excess current by the vaporization or expansion of a mercury column, have the mercury column, which forms part of a circuit between metal caps F, F<1>, formed in a passage a<1>, a, a<2> in an insulating core A, and on the occurrence of an overload, mercury is thrown out and trapped against return by a stationary valve C. To remake the column, the core A is depressed by means of a knob d<2> and then allowed to rise, the mercury that is above the valve flowing back into the passage a and joining the remainder of the column which, during the downward movement of the knob d<2> is pressed upwards owing to the diminution of the space a<2>. The passage in the core A is restricted at a, and the mercury consequently vaporises at this point and throws the mercury in a' out. The mercury fumes escape by a passage d, Fig. 2. Several modifications of cut-outs are described. Fig. 12a shows a cut-out fitted with one form of shock absorber, which is adapted to give way temporarily and form a space for mercury displaced downwards when the column parts. Fig. 13<e> shows one form of indicator for use with the cut-out. On the overload occurring,. the expelled mercury impinges on a plate p<2> on a rod p and drives this into collision with a plunger P. The plunger P is then forced up against a spring p' into its upper position, where it is retained by clips p<8> engaging a groove p<5>. To reset the cut-out, the plunger P is first depressed and then the knot d<2>, the latter carrying with it the core. The cut-out may be held by two insulating holders which are clamped together round it, and the front portion of the holder may be in the form of an indicating tablet.

Title: Power supply circuit
IPC: H02J1/02
Filed: 1974-06-10
Abstract: 1474265 Automatic voltage control HITACHI Ltd and NIPPON ELECTRIC CO Ltd 10 June 1974 [11 June 1973] 25652/74 Heading G3R A power supply circuit includes a series transistor controlled in accordance with sensed variations in output voltage, the circuit operating as a regulated voltage supply when the input voltage is above a given value and as a ripple filter circuit when the input voltage is below the given value. In the latter case, a portion of the series transistor control signal is shunted by a further transistor. As shown in Fig. 2, a load 3 is supplied over a series transistor 1 controlled by a drive transistor 14 receiving control signals from an error detector and amplifier circuit 5-13. When the input voltage V i  is above a certain value, transistors 19, 20 are blocked and the circuit acts as a voltage regulator. If the input voltage falls, the voltage between the emitter and collector of transistor 1 falls and the transistor 19 is turned on by the voltage at its base, which is connected to the junction of a resistor 16 and a constant current source 17. As a result, transistor 20 begins to conduct and shunts part of the error control signal from the circuit 5-13 away from the drive transistor 14. The output voltage V o  therefore decreases, and the circuit operates as a ripple filter. The lower threshold at which the circuit can operate as a filter is determined by the value of a resistor 15, and a further resistor 21 prevents oscillation in the circuit.
