Title: Control circuit for a camera shutter
IPC: G03B9/62
Filed: 1974-12-19
Abstract: 1453159 Shutter release circuit SEIKO KOKI KK 19 Dec 1974 [27 Dec 1973] 55015/74 Heading G2A The circuit first indicates that there is sufficient light and then times the exposure and signals duration of shutter opening. Sw 1  is closed by the shutter release button and photo-conductor Rx and R 1  form a dividing resistor that applies bias to T 1 . If ambient brightness is below a threshold T 1 , is not  biased sufficiently to conduct, consequently T2 conducts and lights L. If the ambient brightness is high Ti conducts and switches off T 2 . As the path to L via R 2  is of high resistance the lamp does not light. Further depression of the shutter release button causes the shutter to open, opens Sw 3  and closes Sw 2 . The capacitor C and R x  then act as a CR timing circuit and when the threshold voltage at T 1  is high enough T2 ceases to conduct, the electromagnet Mg releases the shutter closing mechanism to terminate the exposure. At the same time L ceases to glow, thus indicating end of exposure. In an embodiment Fig. 2, (not shown) Sw 3 , Sw 2  are replaced by a single pole two way switch (Sw 4 ).

Title: Drum winch
IPC: B66D1/22
Filed: 1972-11-29
Abstract: 1418013 Winch drives C KOHLER 29 Nov 1972 [16 June 1972] 55041/72 Heading B8B [Also in Division F2] The drum 1 of a winch is rotatably mounted on a drum shaft 5 which is selectively rotatable in both directions, the drum 1 being driven through epicyclic gearing including ratchet mechanisms whereby the direction of drum -rotation is the same independent of the direction of shaft rotation, but the drive ratios are different. Manual rotation of the shaft 5 inthe clockwise direction causes the drum 1 to be driven through a step-up ratio gearing, and rotation of the shaft 5 in the anti-clockwise direction causes the drum 1 to be driven through a step-down ratio gearing. The reaction wheel 4 is clutched by a friction plate 62 to a wheel 61 axially slidable but rotationally locked relative to a worm-wheel 6 preventing rotation of the plate 4 unless the worm 7 is operated. This clutch 62 acts as a brake which may be released by unscrewing handle 63 whereby the reaction wheel 4 and therefore the drum 1 may free wheel to rapidly pay out cable under the control of the brake. A stepdown transmission ratio larger than the aforesaid step-down ratio is achieved if the worm 7 is manually or motor driven to rotate the reaction wheel 4 in the anti-clockwise direction to drive the epicyclic gear. This step-down ratio is variable by superimposing rotation of the shaft 5 on to the rotation of the worm 7. The wormwheel 6 may be driven in the clockwise direction to act as a paying out brake. In the embodiment of Fig. 5 (not shown) the drum 1 is coupled to the output of the drive gearing through a clutch.

Title: Improvements in diagnostic thermography
IPC: A61B5/00
Filed: 1965-12-31
Abstract: 1,131,952. Temperature indicators. GENERAL ELECTRIC CO. Dec. 31, 1965 [Dec. 31, 1964; Jan.18,1965], No.55391/65. Heading G1D. [Also in Division C4] A composition for use in making the thermographic studies of the human body comprises a finely divided phosphor material, of between 5 to 20 microns particle size, that fluoresces differentially with temperature when irradiated in admixture with a pliable adhesive binder which adhers the phosphor material to a human body skin surface. The composition is described as being particularly useful in the early detection of breast cancer in women in which the cancer will cause the temperature of the body tissues surrounding it to rise relative to corresponding areas on the other side of the body. The composition exhibits floureseent brightness differences corresponding to temperature differences when excited to fluorescence and if the patient is coated with the composition and then uniformly irradiated body surface temperature differences will be converted in visible fluorescent brightness differences which may be photographed using a suitable camera. The phosphor material preferably comprises 60% cadmium sulphide with 40% zinc sulphide by weight and also contains silver and nickel. The lamps used for irradiation are provided with filters to limit the light used to the wavelength range of 3400 to 3800A in the ultraviolet. The phosphor material emits in the wavelength range of 5000 to 6000A and a suitable filter is interposed in front of the camera so as to accept only these wavelengths. A scanning camera may be used in place of the camera previously referred to and this may be used to feed signals to a television receiver. The phosphor material may be applied to the patient in the form of an aerosol spray containing 5 to 15% by weight of the phosphor material, 2 to 5% of a plasticizer and binder, 10 to 20% of alcohol to act as a solvent, and the remainder a propellant. A small amount of talcum powder may also be included to supress specular reflectance. Alternatively, the phosphor material may be incorporated in a suspension of a skin compatible type applied to the body or it may be mixed in a creamy cosmetic base and spread on the body.

Abstract: 1408167 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 Dec 1972 [4 Dec 1971] 55562/72 Heading H4F  In a television camera an image as shown in Fig. 2b is projected on to the pick-up tube target, area M representing an undistorted image of the viewed scene which has had 10% of the red and blue components removed, and areas R and B respectively representing red and blue images formed from the 10% of the red and blue components which have been removed from the light from the scene and subsequently compressed by a factor of, for example, eight in the line scanning direction of the pick-up tube. The resulting image is scanned so that all three areas R, M, B are scanned in alternate line scans 1, 3, 5 ..., only area M being scanned in the intervening line scans 2, 4, 6 .... The resulting signals are passed to a switch 30, Fig. 1, which separates the signal due to area M from the red and blue signals, the signal due to area M being passed to output terminal 34 and used either directly as a luminance signal or for matrixing with the red and blue signals to produce a "true" luminance signal. The separated red and blue signals from switch 30 are passed to a bucket-brigade delay line 32, which receives clocking pulses Q1 from a switch 28 when a red or blue signal is derived and clocking pulses Q 2  of lower frequency from switch 28 during the following period when area M is being scanned, thus producing alternate red and blue signals each of one line duration, which are fed to a switch 37 directly and via a one-line delay line 33, which may be formed as a bucket-brigade delay line. Switch 37 is operated at the end of each line period to produce alternately direct and delayed red signals at terminal 35 and delayed and direct blue signals at terminal 36. Area M may alternatively have a green component image of the viewed scene projected thereon. Areas R and B may both be formed on the same side of area M in which case two bucketbrigade delay lines 32 and two one line delay lines 33 are required. The regions between areas R and M, and M and B on the target of the pick-up tube may be provided with black strips, or the pick-up tube may be blanked when scanning these regions. The pick-up tube may be a cathode-ray tube or an array of photo-diodes.

Abstract: 1322868 Seaming non-metallic sheet material TELEPHON-UND TELEGRAPHEN-FABRIKSAG KAPSCH & SOHNE IN WIEN 1 Dec 1971 [10 Dec 1970 5 April 1971] 55794/71 Heading B5K [Also in Division H1] A top or bottom cap 5 of thermoplastic material is ultrasonically welded to a thermoplastic container body 6 by inserting the cap 5 into the open end of the body 6 until the body rim 6a projects beyond the cap 5 ; advancing an axially vibrating sonotrode 10 against the rim 6a to soften the rim 6a and roll it radially inwards over the rim of the cap, the softened rim 6a becoming trapped during this movement in a closed chamber formed at least partly by the sonotrode 10 and the cap 5; and advancing the sonotrode 10 further thereby applying a welding pressure to the softened material of the rim 6a. In one embodiment, Fig. 1, a top cap 5 is welded to a body 6 to form a primary galvanic cell having a carbon rod 1, an electric contact piece 2, a cast composition 3 and a zinc pot 4. The sonotrode 10 has an annular recess 11 formed by cylindrical walls 11a 11c merging into a thrust wall 11b perpendicular to the lower face 12 of the sonotrode. The diameter of the wall 11a is the external diameter of the body 6. The lower edge of the wall 11c terminates in an edge 13 which, when the sonotrode is lowered, enters an annular channel 5b in the cap 5 and a conical surface 14 engages the inner edge of the channel 5b to enclose the welding zone in an annular chamber. The outer edge of the sonotrode extends downwards in the form of a skirt 16 having a rounded mouth 18. Preferably, the sonotrode is energized before or during its downward movement so that it is already vibrating when it slides over the outer surface of the body 6. In a modification, Figs. 3-6 (all not shown), a low pressure polyethylene bottom cap is welded to a high pressure polyethylene body. In another embodiment, Fig. 7, the sonotrode contains a member 20 to thrust the cap 5 downwards in the body 6 before the welding operation. The member 20, which may be made of steel, is attached to a sonotrode part 10a by a resilient rubber connector 17 and is guided for sliding movement by annular collars 20a, 20b having anti-friction material, e.g. polytetrafluoroethylene, thereon. In use, on lowering the sonotrode, the member 20 first contacts the cap 5 and an annular edge 20c thereof penetrates into the channel 5b and a conical surface 20d thrusts against the inner edge of the channel 5b. The connector 17 is deformed and welding is effected. Air vents 10f, 20f are provided. In a modification (not shown), the connector 17 is omitted and the member 20 is actuated hydraulically or pneumatically independently of the sonotrode. In a further embodiment, Fig. 9, an elastically deformable top cap 5 has been welded to the body 6 and the cell is mounted upside down on a ring 30. When a downward thrust is applied to a bottom cap 7, containing an embedded electric piece 8 and positioned in the body 6, by a sonotrode 10 somewhat similar to that of Fig. 7, the cap 5 is deformed, Fig. 10 (not shown).

Filed: 1973-12-03
Abstract: 1462777 Touch responsive switching systems MAGIC DOT Inc 3 Dec 1973 [12 Jan 1973] 55874/73 Heading G1N In a touch operated switch the touch plate 12 is connected to one input 26 of a differential amplifier 78 to both inputs 24, 26 of which are also supplied an alternating common mode voltage from source 22 and the output of which is coupled to an integrator 16. The amplifier 78 is provided with a capacitor 82 to provide a shunt at the alternating frequency of the common mode voltage for the amplifier output. Initially when touch plate 12 is not touched the amplifier 78 is balanced and the circuit is arranged so that the voltage at 140 is at the supply voltage. Transistor 168 of amplifier 165 is biased off and there is no voltage across integrating capacitor 16. Amplifier 18 including Darlington pair 184, 186 is non-conducting and there is a high impedance across terminals 204, 84. When the touch plate is touched by an operator current flows from source 22 to earth through the capacitance of the operator's body resulting in amplifier 78 being unbalanced. When the output of amplifier 78 changes state 140 is at earth potential so that transistor 168 is turned on and capacitor 16 charged. Amplifier 18 becomes conducting and the impedance across terminals 204, 84 changes to a low value. The lead 30 to the touch plate is twisted in a pair with conductor 28 to obtain a better noise suppression. By appropriate modification of the circuit the potentials at 140 may be opposite to those described above. In a modification, Fig. 2 (not shown) the touch plate 12 is connected to terminal 24 and a capacitor of value equivalent to that of an operator is coupled between input terminal 26 and ground. In this arrangement the differential amplifier is  unbalanced normally but becomes balanced when the operator touches the touch plate.

In a passenger conveyer having an initial accelerated zone (Fig. 1A) and a terminal decelerated zone (Fig. 1C), gradually variable speed in the zones is obtained by elongating and shortening the passenger-supporting surface which is constituted by the upper surfaces of plates 1, the latter being at all times partially superimposed, one upon another adjacent one, the elongation and shortening of the surface being effected by sliding adjacent plates relative to one another. Each plate 1 has pivots 7a, 7b at each side which are each connected to a pivot point of a respective parallel linkage 6a, 8a, 10a, 11a (Fig. 2). The remaining (upper and lower) pivot points of the linkage carry rollers which run in upper and lower guide channel members 17a, 16a, provided in the initial and terminal zones. The channel members diverge or converge in the direction of conveyance to provide the relative sliding of the plates. At the zone (Fig. B) between the initial and terminal zones, the parallel linkages are held in their extreme positions (corresponding to maximum spacing of the pivots of the plates 1) by recesses 21 in a drive belt 3 engaging the pivots 7a, 7b. A handrail 24 is supplemented by a system of handles or grips 25. Each platform may be of ribbed formation and may have an anti-slip surface (Fig. 6, not shown).
