Patent GB-530207-A (GB)
Abstract: 530,207. Time recorders. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1939, No. 19082. Convention date, July 6, 1938. [Class 106 (iv)] A card time recorder comprises time controlled type wheels having means operated by an inserted card for causing an imprint to be taken and a time controlled programme device adapted to be driven by an electric motor upon the periodic engagement of a clutching means, said programme device being adapted to receive settable elements thereon to establish a definite pre-determined programme of operations, and further clutching means which are selectively operated from the pre-set programme device to connect the motor so as to drive positively the machine through a programmed operation. A magnet 25 supplied with current intermittently from a clock controlled switch operates a ratchet wheel 34 through a linkage 28. A detent 35 operated by wheel 34 actuates means to close a driving motor 45 circuit and operates a clutch which connects the motor to a combined type wheel and programme drive mechanism. A cam on the clutch operates means to cut off the motor when the clutch has made one revolution. This motion, through gearing, advances a set of minute, hour &c. type wheels the appropriate amount. The same mechanism also shifts a programme disc 70 which carries castings 88 in which detachable cam elements 89 can be inserted. In the example shown the disc 70 controls horizontal shifting of the card receiver for morning in, noon out &c. recordings and also controls means to shift the printing ink ribbon 135 to cause the printing to take place in desired colours. Fingers 92 are actuated by cam elements 89 and operate a clutch 100 which causes the motor during its periods of operation to actuate gearing to effect the above mentioned operations. The actual shifting of the card carriage is effected by a projection thereon engaging in one or other of two opposite threads on a shift driven from the gearing. The movement of the carriage is reversed by moving the projection from one thread to the other than thus the necessity of reversal for motor 45 is avoided. This mechanism can only operate when one of the projections of a time driven cam 94 serves as a fulcrum for finger 92. The intervals between programme signals are thus lengthened and it is thus possible to work with a smaller wheel 70 than would otherwise be required. When a card is manually inserted in the machine its bottom edge pushes down a pair of levers which put the printing hammer into operation. The card carriage is connected to a rack co-operating with an interlocking pawl in the printing mechanism. Only when the carriage is in correct printing position can the pawl drop in between the teeth of the rack and allow printing to take place. On each printing operation a pin on the printing gear actuates a lever 212 which operates the ribbon drive shaft 216 through a ratchet. The ribbon can also be shifted manually by a lever 219. The machine may be provided with a clock face 230 with hands 231 and 232 driven from the type wheel mechanism.

In a colour television receiver which responds to a signal which includes synchronizing " bursts," the phases of which differ in alternate lines, and in which the reference oscillator is synchronized to the " bursts " with the aid of a phase detector 1 which produces a saw-tooth signal at half the line frequency in the presence of " bursts " and a direct voltage in the absence of " bursts," a tuned amplifier 2 is provided to derive from the saw-tooth signal a sinusoidal signal which is rectified and filtered in a circuit 4 to produce a direct voltage which controls the colour amplifier 5, whereby the receiver is caused to produce a colour picture when " bursts " are received and a monochrome picture when " bursts " are not received or are inadequate for proper colour operation. The sinusoidal signal also controls a multivibrator of a colour switcher 3 which changes over the phase of one of the modulation components of the colour signal. The direct voltage produced by phase detector 1 in the absence of " bursts " may be applied over lead 6 to block amplifier 2.

A process for diffusing boron into a given surface of a silicon semi-conductor body comprises the steps of passing a decomposable gaseous boron compound and an oxygen containing gaseous compound over the semiconductor surface while it is maintained at a temperature, between 920 and 1050 C., at which the compounds react to form borosilicate glass on the surface, then decomposing the gaseous boron compound in a reducing atmosphere at a higher temperature, such as 1215 C., so as to deposit free boron, and finally heating the body in the reducing atmosphere at this higher temperature for a sufficient time to allow the free boron to dissolve in the borosilicate glass and boron from the borosilicate glass to diffuse into the body. The boron compound is a boron tribromide, a boron halide or diborane. The reducing atmosphere is hydrogen, which reacts with the free bromine to prevent the formation of undesirable silicon bromine compounds on the surface of the body.

Abstract: 1,222,890. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Nov., 1968 [21 Nov., 1967], No. 53996/68. Heading H4K. In a program controlled exchange system a translator is employed which is used in one direction to obtain data, such as equipment number and class of service, in response to an input directed by the corresponding directory number, and is used in the other direction to obtain the directory number from the equipment number. The translator is a ring core translator with one wire per directory number and comprised of one thousand wire units. Selected in accordance with a directory number a wire produces an output code of from 30 to 40 bits. If the directory number corresponding to an equipment number is required the translator is sequenced over all its inputs until an output is produced containing a match with the equipment number in question, the input giving the match indicating the wanted directory number. The exchange processor has a program of the wired type and the processing equipment employs integrated circuits and is duplicated with online and off-line equipments changed over periodically. The switches are preferably crossbar switches with split vertical commons, the network comprising a number of line units as described in Specification 1,127,384. Registers store one digit at a time each digit being cleared by the processor for storage with call particulars before the next digit arrives. As each digit relating to a call is accumulated, application is made to the translator from the output of which it can be determined whether the number of digits received is sufficient for a valid translation or whether should wait until another digit or digits have been received. Senders also store one digit at a time as supplied by the processor, outpulsing being by means of an integrated circuit counter.

Abstract: 1,199,247. Cathode-ray tubes. TOKYO SHIBAURA ELECTRIC CO. Ltd. 21 Nov., 1968 [22 Nov., 1967; 6 Jan., 1968], No. 55371/68. Heading H1D [Also in Divisions H3-H5] The Specification describes an infra-red television apparatus comprising an image pick-up means for obtaining two video signals respectively_corresponding to the infra-red and to the visible rays involved in incident light from a foreground subject and a colour television reproducing means capable of reproducing images, respectively corresponding to said two video signals, in different colours. The image pick-up means may comprise two pick-up tubes 7 and 9, Fig. 1, respectively irradiated with the infra-red and the visible components of the incident light by means of dichroic mirror 5. A colour television receiver 12 displays the infra-red component as red, and the visible light component as green. A hot object 1, e.g. aircraft exhaust, against a cold background, e.g. sky, will appear as red against a green background. The spectral ranges of tubes 7 and 9 are shown as B and A respectively in Fig. 2 (not shown). The image pick-up means may also comprise a single vidieon pick-up tube, Fig. 3, comprising, as well as normal cathode 33 and grids 34, 35 and 36 a target face comprising a glass substrate 37, a deposited striped filter 38 comprising spaced parallel stripes of germanium or silicon opaque to visible light but transparent to infrared, a transparent conductive layer 39 of tin oxide and photo-conductive layer 40 of lead oxide or lead sulphide. The electron beam 43, raster-scanning the target normally to the stripes, thus produces at output 46 a signal having alternate components, representing the infra-red component only (through the stripes) and the infra-red component plus the visible light component (through the spaces between the stripes) respectively. The infra-red component is thus continually scanned and has a lowfrequency range C, Fig. 6, whilst the visible light component has partly a high-frequency range D, centred about the scanning frequency Fc of the stripes, and partly a low-frequency range also shown as C. Range C and D are thus separated out from output 46 by means of low-pass filter 48, Fig. 7, and band-pass filter 47, respectively, and the visible light component of range C is removed by detecting the output of 47 in means 49 and subtracted the resultant from the output of 48 in means 51. Detector 49 thus produces at output 50, the visible light component, whilst the infra-red component appears at output 52.
