Abstract: 1,031,108. Devices for engaging and lifting articles. STICHTING WATERBOUWKUNDIG LABORATIUM. Sept. 21, 1964 [Oct. 3. 1963], No. 38372/64. Heading B8H. To lift an object 2 a bag 3 containing fluid 9 is lowered over it and a wire 7. 8 attached to the inside of the bag at 6 is raised. This raises the object, which is gripped in the cavity 10, and allows the object to be substantially completely enveloped owing to the fluid pressure. At this stage the wire 5 attached by a member 4 to the top of the bag is raised at the same rate as the wire 7, 8. The bag may contain liquids, gases or granular solids, e.g. sand, glass beads or iron grains. The member 4 may be tubular and closed by a cover with a seal through which the wire 7 passes. The wire 7 may be replaced by a flexible or rigid tube which may be in open contact with the cavity 10. Alternatively, the tube may be closed at the bottom but have holes which allow fluid to pass to the tube from the sack. The device may be used for lifting articles which are immersed in liquid.

Filed: 1964-09-21
Abstract: 1,071,959. Typewriting &c. W. H. WOLOWITZ. Sept. 21, 1964, No. 38373/64. Heading B6F. The obliteration of errors is effected by a white or paper-coloured pigment either on a separate ribbon 78 or formed as a band on the " ordinary " ink-ribbon 64. In the embodiment shown, the obliterating ribbon 78 is fed from a spool 80 through separate guides 86 in a vibrator guide 46, and fed to waste by rollers 88, 90. These rollers are held against rotation by their operating slide 92 and spring 102 and are rotated only during an errorcorrecting typing. Feeding is effected by a lever 94 and a wire 100 which has a loop 106 movable into or out of engagement with an operating lever 104. The wire 100 is moved, so it engages with the lever 104, by end 108 of a link 110 attached to the vibrator setting lever 62 connected by link 60, lever 58, slide 56, and dial 20 which can be adjusted so that the printing occurs either in the black or the error obliterating band of the ribbon 64. There are two back-spacing keys, a normal key 16 which operates a lever 30 and a backspace pawl 26; at the same time a crank 118 operates the lever 58 to ensure that the black area of the ribbon is in printing position. A second or auxiliary back-space key, used during error correcting, is also connected to the backspace pawl via parts 42, 44 and a flexible connection 112 to the lever 58 ensures that the white area is arranged in the printing area during back-spacing when obliteration by overtyping is required.

Abstract: 1,064,587. Making dies; making machine knives. M. D. MARTIN. Sept. 21, 1964, No. 38440/64. Heading B3A. [Also in Division B4] A method of making a die rule for a rotary cutter device includes the steps of providing a metal strip with a longitudinal cutting edge and a base edge, forming spaced notches transversely in the base edge of the strip,. bending the strip to the required contour and then forming the rule to a curvature corresponding to the radius of rotation of the rule about the axis of the rotary cutter by heating the base of each notch in turn and narrowing the mouth of the notch. The rule so formed is mounted by providing a primary base bent to the required curvature, forming slits through the base in a pattern conforming to the contour of the die rule, pressing the die rule into the slits so that the cutting edge protrudes from the convex face of the primary base and mounting the primary base on a curved secondary base adapted to be secured to the rotating member of the rotary cutter device. The strip 1 has a cutting edge 2, and a base edge 3 having legs 7 formed by notches 8. The notched strip is bent to the required contour, Fig. 2 (not shown) and then formed to the required curvature, Fig. 4, by heating the base 9 of each notch and applying pressure to the legs. The primary base (11), Fig. 7 (not shown), is formed of laminated wood and slotted at (14) to receive the legs 7. To increase the frictional grip of the legs they are bent out of the plane of the strip alternately in opposite directions, and may be bifurcated. The primary base (11) is then mounted on the secondary base (12), Fig. 8 (not shown) by screws (19). Prior to assembly the mating surfaces are coated with a releasing agent such as a silicone wax and a layer of cold-setting epoxy resin is applied between the faces to ensure perfect seating. In a modification the slots (14) are contiguous and the plug removed is replaced after the rule has been inserted in the aperture and is retained by a screw.

Abstract: 1393484 Radiographic scanner PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 Aug 1973 [23 Aug 1972] 39213/73 Heading H4F The distribution of radio-activity as a subject on a bench 4 is determined from above and from underneath by respective mechanically coupled scanners 2, 3, Fig. 1. The scanners 2, 3 feed their signals to respective write heads 6, 7 mounted on an arm 5 coupled to the scanners. If the write heads, especially head 7, are rigidly coupled to the arm 5 and so move over reproducing surfaces 8, 9 in synchronism with the movements of the scanners, the reproduction on surface 8 will be the radio-activity distribution "as seen" by scanner 2, but the reproduction on surface 9 will be the "left to right" inversion of the distribution "as seen" by scanner 3. Such representation may not be desired, and to allow the reproduction on surface 9 to be as described or to be "as seen" by scanner 3, the head 7 is arranged to move parallel with head 6, either in the same direction for the first mode or in the opposite direction for the second "as seen" mode. Head 7 is thus coupled to head 6 by a belt 10, Fig. 2, moving on pulleys 11, 12 with head 7 being connected to the same half of the belt as head 6 for the first mode, and to the opposite half for the second mode. The belt may be replaced by two racks 10a, 10b, Fig. 4, rack 10a being connected to head 6 and the two racks caused to move in opposite directions by coupling pinion 20. Head 7 is connected to either rack depending on the desired mode.

Abstract: 1506698 Colour television ROBERT BOSCH GmbH 22 Sept 1976 [27 Sept 1975] 39256/76 Addition to 1506413 Heading H4F Apparatus, for automatic reduction of colour balance errors in a colour television picture, is as claimed in claim 1 of the main patent and wherein the values indicative of chromaticity are colour difference signals and the fourth means for integrating said colour difference signals comprises a circuit having a different time constant according to the output of said third means. As described, changeover switch 2' passes the colour difference signal from input 1<SP>1</SP> when the input 9 is "up", i.e. it indicates that the luminance is within the desired range and the colour saturation is below a given threshold, and integrating circuit 3', 4', 5', 7' provides a signal at 6' to control the colour corrector (not shown) as in the main patent. When the signal at 9 goes "down", capacitor 7' discharges through circuit 2', 3', 4', 7<SP>1</SP>, 8', the time constant of which is longer than the first mentioned circuit. This is said to prevent the build up of colour errors and the over correction of colour balance errors.

Title: Improvements in or relating to electric light switching devices
IPC: B60Q1/14
Filed: 1957-12-18
Abstract: 858,968. Light sensitive switching apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 18, 1957 [Dec. 21, 1956], No. 39354/57. Class 40(3). In photo-electric switching apparatus for controlling, e.g. a vehicle's head lamps or a road traffic crossing, a first photo-cell when illuminated by an approaching light source switches the device to a first condition and a second cell, illuminated by the light source in passing switches the device to a second condition if the first cell is not illuminated. As applied to the control of the head lamps of a vehicle, cells I and II are energized respectively by approaching and passing light. On switching on the device (switch 7) the charge current of condenser 10 energizes relay 3 which holds in this position via a circuit through relay contacts 31, 41 and 51 and switches on the vehicle's headlights 14. When light from an approaching vehicle reduces the resistance of cell I relay 4 operates and breaks the hold circuit of relay 3 whereby the vehicle's lights are switched to dim light 15. When the approaching vehicle passes cell II is illuminated, its resistance drops and relay 3 is re-energized and remains in this condition if relay 4 is deenergized by the reduction of light on cell I. When the approaching vehicle dims its lights before relay 4 is operated the resistance of cell I suddenly increases so that condenser 9 charges via relay 5 which operates and breaks the hold circuit of relay 3 which on releasing switches the lamps to dimlight. If the approaching vehicle does not dim its lights the resistance of cell I drops to a very low value and a lamp 11 in series with the cell illuminates a third photo-cell III via which relay 3 is re-energized and the lights are switched to headlights, however since the relay's hold circuit is broken at relay contact 41 the relay releases again and the lamps switch to dimlight. A flashing signal is produced which continues until the approaching vehicle dims its lights. Specification 798,188 is referred to.

A honeycomb material for use as a laminate core, especially for architectural panels, comprises strips, e.g. of paper or cardboard having bands of adhesive on each of their surfaces, the bands A on one surface of each strip being so spaced that they do not register with the centres of the spaces between the bands B on the other surface of that same strip, so that when a plurality of strips is stuck together and the assembly is opened out to form a honeycomb the cells so formed are not regular hexagons but are distorted. It is desirable that the ratio of the spacing between the adhesive bands and the width of the bands is from 4À5: 1 to 20:1, preferably 9:1. The core so formed may be placed between transparent or translucent skins, e.g. of glass-fibre reinforced resin and the inner surface of one skin may be coloured in patches bounded by the honeycomb cell walls, these also being coloured, e.g. black, to imitate wrought iron. The skins may be of wood and the laminate may be curved. The honeycomb material is made from sheets laminated together by bands of adhesive to form blocks which are subsequently sliced and the slices pulled open to separate the layers into the open cellular state.
