Filed: 1925-09-01
Abstract: 266,564. Television, Ltd., and Baird, J. L. Sept. 1, 1925. Television.-The view or image is explored at the transmitting station or reconstituted at the receiving station by two or more series of image-casting devices carried bv a common support. Synchronized rotary discs 1, 10 at the transmitting and receiving station respectively may each be provided with two spirals of holes or lensed holes, one spiral within the other. The imagebeams from the outer and inner spirals 3, 4 of the disc 1 mav be directed on to corresponding lightsensitive cells 8, 7 in circuit with corresponding light sources 13, 14, respectively at the receiving station. A partition may be provided between the spirals 3, 4 to limit the light from each to' the corresponding cell 8, 7. This partition may be rigid with the disc 1 or rotatable relatively thereto. Alternatively, a single cell, exposed by a shutter or reflector to the spirals 3, 4 alternate-- ly, may be used with a single light source' similarly exposed alternately to the spirals 11, 12 of the disc 10. Each spiral may explore only a particular strip of the view or image. For stereoscopic effect, however, two stereoscopic images may be explored one by each of -the spirals 3, 4, or the whole of the original view or image may be explored by both spirals, adjacent lenses in the two spirals being arranged to produce stereoscopic images one of which is directed on to each of the cells 8, 7. At the receiving station the stereoscopic images produced by the spirals 11, 12 may be superposed or viewed through a stereoscope. For colour television a separate colour screen may be used in conjunction with each spiral 3, 4 and a similar screen in conjunction with the corresponding spiral 11, 12. Alternatively the light sources 14, 13 may be of different colours, and the cells 7, 8 be each sensitive to the particular colour of its associated light source. Specification 253,957 isreferred to.

Title: Improvements in and relating to denatured alcohols
IPC: C12F5/00
Filed: 1943-12-31
Abstract: Alcohols are denatured by the addition thereto of aldehydes such as 2-methyl pentanal or 2 : 4-dimethyl pentanal, obtained by oxidizing a mixture of higher alcohols produced in the high-pressure synthesis of alcohols from hydrogen and oxides of carbon.  For the production of the aldehyde-containing products, a fraction consisting of a mixture of aliphatic branched chain higher alcohols of B.P. 108 DEG -200 DEG C. is preferably used.  Typical alcohols in the higher alcohol mixture obtained in the synthesis are listed and range from propanols to hexanols; in general, the alcohols contain from 5 to 14 carbon atoms.  The oxidation may be effected by passing the alcohol mixture in the vapour phase over a catalyst in the presence of air or oxygen-containing gas.

Title: Improvements in or relating to an alarm system with means for eliminating the effectof unwanted signals
IPC: G08B17/06
Filed: 1954-07-28
Abstract: 770,681. Theft and fire alarms; detecting objects by ultrasonic vibrations. KIDDE & CO., Inc., W. July 28, 1954 [Aug. 3, 1953], No. 22030/54. Drawings to Specification. Classes 118(1) and 118(2). In an alarm circuit which may comprise a theft and fire alarm of the type described in U.S.A. Specification 2,655,645 and operating on the Doppler principle to detect motion in a confined space, the occurrence of an event to which the alarm is designed to respond causes a low-frequency electric signal to be developed, this signal being subsequently passed to an alarm-control circuit through limiting, rectifying and averaging circuits whereby the alarm is actuated only by signals whose duration exceeds a predetermined minimum, spurious signals of short duration failing to actuate the alarm. In the apparatus described, a 19 kc/s. ultrasonic oscillation is transmitted into a confined space such as a room and reflections are received by a receiving transducer, the output from which is amplified and then heterodyned with a signal of the transmitted frequency. In the event of motion occurring in the room, the reflected signals will suffer a change in frequency due to the Doppler effect and a frequency-difference signal will be derived as a result of heterodyning the received and transmitted signals. This signal, if derived, is applied to a valve limiter circuit to render the response of the alarm circuit insensitive to variations in the amplitude of the frequency-difference signal. The limited signal is then applied to a selenium rectifier followed by an integrating circuit whereby there is derived a unidirectional-voltage output whose value is independent of the amplitude of the signal derived by heterodyning the transmitted and received signals but is dependent upon the length of time for which this signal persists. This unidirectional output is applied to a normally conducting valve having a relay in its anode circuit, the relay controlling an alarm device and the valve being so biased that the anode current is switched off and the relay actuated only when the unidirectional signal exceeds a certain minimum value. Hence the alarm circuit responds only to signals which persist for longer than a predetermined minimum time and provides protection against spurious signals which generally are of short duration.

Abstract: 1440170 Soldering DR EUGEN DURRWACHTER DODUCO 17 May 1974 [5 July 1973] 22109/74 Heading B3R In making a solderable composite body containing silver-cadmium oxide an assembly is formed of an intermediate layer of silver-copper alloy or silver-copper oxide located between a layer of silver or silver alloy and a layer of silvercadmium alloy, the layers are metallurgically joined together and the cadmium is subsequently internally oxidized, the joining comprising heating the assembly without applied pressure until the silver-copper alloy or silver-copper oxide reaches a pasty stage. In an example a Ag-13-4% Cd with 0À2% Ni alloy is melted, cast into a bar and rolled to form a plate. One surface of the plate is brushed clean, a plate of AgCu 2 O is placed on this surface followed by a silver plate. The assembly is heated in a furnace without the application of pressure until a pasty stage of the intermediate layer is reached. The joined assembly is rolled annealed and rolled again and plates stamped from this rolled body are heated at 800 C. for 15 hours to internally oxidize the cadmium. In another example a plate of Ag-9% Cd alloy containing 0À2% Ni is brushed clean on one side, a plate of Ag-15% Cu alloy is placed thereon followed by a plate of Ag, a plate of Ag-15% Cu alloy and a Ni plate. This assembly is heated without applied pressure in a protective gas until the AgCu alloy plates reach a pasty stage. The joined plate is hammered and rolled with salt bath annealing and the rolled strip is heated at 800 C. for 10 hours to internally oxidize the cadmium. Electrical contacts can be stamped from this strip.

Title: Nursing unit
IPC: A61J11/00
Filed: 1959-06-29
Abstract: 921,442. Infants' feeding-bottles. PYRAMID RUBBER CO. June 29, 1959 [March 2, 1959], No. 22286/59. Class 66. The nipple of an infant's feeding-bottle has its flange 30 clamped against the upper surface 18 of the bottle neck by a screw cap 42, the flange so being provided around its outer periphery with an upstanding ridge 35 so that, as the cap is screwed on, this ridge is pressed down causing the rubber 46 at the lower side of the flange to flow down into a rabbet 20 on the bottle and so form a collar around the bottle lip. The flange 30, which has a reduced web portion 32 for greater flexibility, is also provided with one or more vent passages 34. The flat top portion 36 of the cap is snapped into position around the nipple between flange 30 and a shoulder 26 on the nipple, radial and vertical lugs 27, 28 on the nipple serving to space the cap from the shoulder 26 and sides of the nipple respectively so as to leave air passages therebetween leading to an annular channel 37 between the underside of cap top 36 and top of web portion 32. In use, when there is reduced pressure inside the bottle, flange 30 flexes inwardly allowing air to pass between the underside of cap top 36 and through passages 34 into the bottle. An annular bead 40 is disposed on the underside of the screw cap just inside the ridge 35 so as to overlie the middle of the bottle lip so that, as the cap is screwed on to depress the ridge 35 as described above, the bead 40 is forced down into the body of the flange 30 maintaining its interengagement with the ridge 35 and so forming a double interlock of the flange with the screw cap and bottle. It is stated that the bead will also cause rubber to flow towards the vent holes and reduce their size. When it is desired to use the bottle for storage of food, the nipple is inverted, Fig. 3, the ridge 35 then fitting into rabbet 20. A sealing disc is disposed between the nipple and the screw cap, said disc having a thicker central portion 52, thinner peripheral portion 54 which overlies the vent holes 34, a circular upstanding flange 56 fitting inside the aperture in the top 36 of the cap and a finger grip upstanding flange 58. When the cap is screwed down, the thick portion 52 pushes down on the nipple flexing the web 32 and sealing over the mouth of the nipple. A modification is described, Figs. 4 and 5 (not shown), in which the ridge 35 is made slightly smaller in volume and an additional partially preformed ridge is provided on the underside of the nipple flange, the combined volumes of the two ridges being slightly greater than that of rabbet 20.

Patent GB-1147028-A (GB)
Title: Data communication system employing an asynchronous start stop clock generator
IPC: G06F13/38
Filed: 1966-05-19
Abstract: 1,147,028. Data transmission systems. GENERAL ELECTRIC CO. 19 May, 1966 [19 May, 1965 (3)], No. 22404/66. Heading H4P. The first bit in each group of bits in a digital transmission system starts a clock pulse generator whose output controls the read-in of the bits to a store. The clock pulses also pass to a counter which has a capacity at least as great as the number of bits in each group. When the counter is full it stops the generator. The generator is used in an error-correcting half-duplex transmission system. To set up a call from a station A to a remote station B, A communicates with B and switches to data communication either manually or automatically. When B is ready to receive data it sends a tone to A. If B is an unattended station A now sends preset data which readies a punch at B. Data is now sent from A: each group of bits consists of a start bit, n bits representing an item of information, n further bits the inverse of the first n, and a stop bit. Frequency shift transmission is used, and a pilot tone accompanies the data to indicate the direction of transmission. After a block of groups an endof-block signal is sent, in response to which, if there has been no error, B returns a tone to A and starts to transmit data. If there has been an error B sends no tone and consequently A reverses its store by one block length, sets up communication with B again, and repeats the block. Clock generator, Fig. 9 (not shown), comprises a gating arrangement which when fed by a start pulse triggers a first monostable giving a ¢-bit pulse. This pulse passes to the output, to a second monostable, and to a counter. The second monostable feeds a ¢-bit pulse to the gating arrangement which is also fed by the counter output. The counter has a capacity equal to n + 2 bits and when not full allows the gating arrangement to pass the ¢-bit pulse from the second monostable to trigger the first monostable again, so producing a series of clock pulses. When the counter is full the series ceases. Transmitter.-Parallel n-bit data from a punched tape is fed to a shift-register which is read out under the control of clock pulses. The output is fed back to the input so that two n-bit sequences are produced. A gating circuit adds start and stop bits and inverts the second n-bit sequence. The resulting group is transmitted. Receiver.-The start bit triggers the local clock pulse generator which controls the read-in of the first n-bit sequence to a shift register via a gating circuit which removes the start and stop bits and feeds the inverse of the second n-bit sequence to a comparator which compares the first and inverted second n-bit sequences bit by bit. The shift-register output passes to a store from which, if there was no error, it is read to a punch. If error is detected the store is cleared and prevented from receiving any further data during the rest of the block.
