Filed: 1964-11-17
Abstract: 1,038,207. Skin packaging. STANLEY WORKS. Nov. 17, 1964 [Nov. 19, 1963], No. 46726/64. Heading B8C. The substrate 36 (Fig. 5) of a skin package has a mould d portion 32a to prevent upward curling of the edges of the package. A moulded groove 38, or grooves extending radially from the packaged object may also prevent curling at the edges. In the embodiment described a fibrous substrate, e.g. made of wood pulp, hemp, jute, or caroa, is placed on air pervious support member 2a (Fig. 4, not shown) comprising a metal tray 4a, fibrous elements 10a, 16a, screen elements 8a, 14a, and a grooved moulding element 18a of fibrous material or plastics foam. A plastics film 28a is supported by its edges above the article 26a and is heated so that it deforms. Air is then sucked through the support member and the substrate so that the film is drawn into tight contact with the article and with the substrate, and so that the film and substrate are drawn into the grooves in the moulding element. The film 28a may be surface treated so that it bonds directly to the substrate 36, alternatively adhesive may be applied to the substrate. Before placing the substrate 36 on the support member the lower surface may be moistened, and the evaporation of this moisture during the skin packaging process assists in preventing the substrate 34 from curling. Several articles may be simultaneously skin-packaged on a single substrate 34 which may then be cut along the base of the grooves 20a to give individual packages. Perforations may be provided on the substrate near the article to assist in drawing the film 28a about the article when the article is very large. Other perforations may be provided for hanging the packages or for tearing the substrate to open the package.

Title: Tuning control circuit arrangement
IPC: H03J5/02
Filed: 1974-11-07
Abstract: 1469798 Receiver station selection INTERNATIONAL STANDARD ELECTRIC CORP 7 Nov 1974 [14 Nov 1973] 48143/74 Heading H3Q In a tuning control circuit having digital stores 1-3 each storing tuning data of a required station, a comparator T1, T2 compares a voltage derived from a manually settable potentiometer R9 with a voltage derived selectively from one of the stores 1-3, whereby when the potentiometer has been set to a required station the comparator causes the contents of a selected store 1-3 to be so altered as to contain data representative of the required station. By closing switches 8, 13 and K1 and adjusting R9 to the required station an AND gate 5 or 6 is enabled by the output from the comparator T1, T2 depending on the direction of stepping required for the selected store 1 to be driven by a pulse generator 7 to obtain the tuning voltage. The forward or backward input V or R of the store 1 is fed with pulses from the generator 7 until the input voltages to the comparator T1, T2 balance and the change in output of the comparator T1, T2 then disables the AND gate 5 or 6 to maintain the store providing the selected tuning voltage which is applied via a time constant and filtering network 11 and output 18 to varactor diodes in a radio or TV receiver. The stores may be digital binary stores employing D-A converters, MNOS shift registers or electronic stepping switches. The programming is effected with the aid of sensors. Each of the switches 8, 9, 10 and 13, 14, 15 are disclosed as electronic switches. The other stores 2 and 3 may be similarly set to required stations. When all of the stores have been programmed the pulse generator 7 is disconnected and the potentiometer R9 is prevented from acting on any other store. Waveband selection of the receiver is effected via 19, 20 automatically after each complete counting cycle and is carried out by a key contact K2. Actuation of key K2 effects residual charging of C1 across R8 and via D4 as well as across the input resistor of gate 5. The residual charging process together with the residual voltage and the time constant R8.C1 determines how long the gate 5 remains open to the forward setting pulses controlling the connected store to the end of its counting cycle and to the starting of the wave range switching. By suitably dimensioning the previous charging of C1 and with the slider of R9 near its positive voltage maximum it is ensured that when the key K2 is closed the gate 5 closes sufficiently quickly that there is no skipping of one wave range. On the analog output voltage of the store reaching its maximum switch-over is effected to the next range.

Title: Method and apparatus for testing image correlation-
IPC: G01D5/38
Filed: 1972-10-19
Abstract: 1393737 Correlation techniques ERNST LEITZ GmbH 19 Oct 1972 [26 Nov 1971] 48187/72 Heading H4D To determine the degree of mutual correlation between two individual images formed via respective objectives the images are caused to pass through at least one slit oscillating in a direction perpendicular to the line of the slit and the images so modulated are separated out for detection by respective photoelectric means and conversion to corresponding electrical signals for feeding to a correlation detecting circuit. In the range finder of Fig. 1 each image is individually polarized at 6 and 10 and superimposed by means of mirrors 7, 8, 11 and 9 on to a single oscillating slit 5<SP>1</SP>. After passage through the slit the two images are separated out by polarization splitting prism 12 and detected by respective photocells 13 and 14. With switches 15 and 61 in the position shown, one of the signals, that from detector 14, is differentiated before being passed to one input of a correlation circuit 16. Since the other input of the circuit 16 is fed with the output of detector 13, maximum correlation of the images is shown by a zero output from the detector. This zero output may be shown on an indicator 18 and also fed to a solenoid 20 whereby mirror 7 may be adjusted to bring the two images exactly on top of each other. With switches 15 and 61 in the positions not shown the differentiator 17 is by-passed and maximum correlation between the images is detected by a maximum output from correlator 16. The single slit 5<SP>1</SP> may be replaced by a grating 21 (Fig. 2, not shown) which if transparent and comprising alternate stripes giving different polarizations may enable the superimposed images to be directly viewed through the grating. The images may be individually modulated by respective gratings 31, 32 (Fig. 3A) enabling a direct view to produce a stereoscopic image. The correlation circuit 16 may be replaced by a difference amplifier 45. The images may be directly viewed through reticule bearing sheets 60, 63 enabling exact visual super-positioning of the two images to be detected.
