Abstract: 1456165 Electronic control of cameras FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 17 Oct 1974 [6 Nov 1973] 45026/74 Heading G2A  A camera has an electronic control arrangement which includes a stepping switch actuated by an impulse generator, the switch setting up in succession the various camera functions involved in making an exposure, and in one stage of the stepping switch movement the film transport motor is switched on, and then is switched off again after film transport has been effected. As shown, the film winds off a spool 12, passes between a gate 13 and pressure plate 24, round a cog-wheel 22 whose teeth 22a engage in the film perforations, and is taken up on a spool 11 which is driven by a motor 9 via a cog-wheel 10'. The stepping switch 15 is actuated by the impulse generator 16 in such a way that on each impulse the switch emits a signal to one of its outputs 17, in a fixed order of succession, to operate such camera functions as raising or lowering the mirror in a reflex camera, setting the diaphragm, and opening and closing the shutter. The film stepping unit 7 is connected to the electric control section 5 by leads 6, and inside the unit 7 the lead 6 is interrupted by a film scanning contact 18 and a pair of contact springs 19a, 19b. These springs can be inter-connected by an electrically conductive contact path 20 mounted on a disc 21 which is driven by cog-wheel 22. Contact 18 is opened when the camera housing is opened to insert or remove the film. When film is inserted, and the housing closed, contact 18 is closed. A transistor circuit is connected with a particular output 17 of stepping switch 15, so that when the switch reaches this stage, the gap between contacts 19a, 19b is bridged, and the motor 9 is energized, so driving spool 11 to transport the film. This in turn drives cog-wheel 22 and hence disc 21. Thus, as the stepping switch moves on to another output stage, and the transistor is blocked, the contacts 19a, 19b remain connected by path 20, and the motor remains operative, continuing to drive the film, until the contacts reach the gap between two sectors of path 20. The motor circuit is thus interrupted, and film transport ceases. The conductor path 20 is so designed that exactly one frame of film is transported. In the arrangement of Fig. 5 (not shown), a counter device is incorporated, and the motor may be switched off automatically after a predetermined number of film frames (e.g. 12 or 24) have been wound on.

Abstract: 1,142,426. Decoders. INTERNATIONAL BUSINESS MACHINES CORP. 5 Oct., 1967 [6 Jan., 1967], No.45429/67. Heading G4H. The frequency of an input signal f(t) which may have any one of n predetermined frequencies is determined by mixing the input signal with n-1 reference frequencies and feeding the resultant n-1 beat signals to associated low pass filters which each generate an output signal when the input signal f(t) is one of the pair of frequencies adjacent the associated reference signal. The combination of outputs from the filters represents the frequency of the input signal. In the embodiment described in which the input signal may have one of three frequencies the outputs from the filters 25, 26 are fed to detectors 27, 28 which generate a " 1 " signal in response to an output signal from the associated filter, the outputs from the detectors being fed to AND gates 31, 32, 33 and inverters 29, 30 so that a signal is generated on one of three lines 1T, 2T, 3T to control a device 34.

Title: High Gain Antenna System with 360° Coverage
IPC: H01Q15/04
Filed: 1966-10-14
Abstract: 1,166,105. Aerials. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Oct., 1966 [20 Oct., 1965], No. 45949/66. Heading H4A. An aerial comprises a radio-frequency lens of substantially circular outline enclosed between parallel conductive plates, said lens focusing an incident wavefront to a point near its perimeter, first means for coupling said wavefront to a first half measured in thickness of the lens, second means for coupling energy from the second half measured in thickness of the lens to a focal point, and third means for coupling energy internally between said first and second lens halves. As described, a dielectric lens 4, Figs. 1a, 1b in the form of a circular disc is clamped between two conductive members 1, 2 by means of screws 5 engaging tapped holes in conductive face plates 8, 9 which are cemented to the said lens. The lower member 2 contains a plurality of waveguide apertures 3 whose ends are closed by a conductive septum 4, fixed to the member 2 by screws 7, which is located mid-way in the thickness of the lens 4, and which forms a throat with the underside of the member 1. The waveguides 3 are thus coupled to the lower half of the lens 4 and the throat, which extends into a horn structure constituted by flaring out of the extremities of the members 1, 2, is coupled to the upper half of the lens 4. The said lens is arranged to focus an incident wavefront upon a diametrically opposite waveguide, either by constructing it as a Luneberg type lens or, by approximation, with a uniform dielectric constant. The coupling arrangements are such that there is a substantial measure of isolation between each channel, an equivalent " tee " configuration existing (Figs. 6a. 7a, not shown). In another embodiment, a geodesic type Luneberg lens comprises shaped parallel conductive members 39, 45, Fig. 4b, between which is a parallel dividing member 44. A plurality of coaxial probes 42 is spaced around the lip of the member 39 and the lips of the members 44, 45 are flared out to form a horn. Coupling between the two halves of the lens is provided by essentially circumferential slots 44a and is equivalent to a hybrid configuration (Figs. 6b, 7b, not shown). It is stated that independently available beams covering between them 360 degrees in azimuth are obtainable, and that elevation control is possible by adjustment with a ground plane. The beam shapes may be modified by using suitable baffles and they may have horizontal or vertical polarization. Scanning is possible by energizing the waveguide feeds in succession. The output throats may be coupled to the elements of an aerial array instead of being extended into flared horns.

Title: Process for the production and stabilisation of bisketenes
IPC: C07D213/20
Filed: 1962-12-10
Abstract: The invention comprises bisketenes, of general formula <FORM:1021520/C2/1> wherein R1 and R3 are alkyl groups, and R2 is a cycloalkyl or aryl group, or wherein R1, R2 and R3, together with the carbons linking them, form part of a cycloalkyl ring.  The bisketenes may be prepared by reacting (1) dicarboxylic acid dihalides, of the general formula <FORM:1021520/C2/2> wherein the symbols have the same meaning as above, in solution in a non-polar solvent that is inert to the reactants and the resulting bisketenes (e.g. hexane, ether, chloroform or benzene), with (2) a tertiary nitrogenous organic base, in absence of oxygen and moisture, preferably between - 10 DEG  C. and + 50 DEG  C.  Preferred bases are tertiary aliphatic amines if a solution of bisketene in the free state is required, the base hydrohalide being precipitated out.  Replacement of the aliphatic amines by tertiary nitrogenous heterocyclic bases (e.g. pyridine, picoline), gives stable adducts of the bisketene and the base hydrohalide, which precipitate from the non-polar solvent, and these may be stored indefinitely if kept dry.  By dissolving this adduct in a suitable inert polar solvent (e.g. dioxane, D.M.F.), the bisketene is returned to a normally reactive state.  Alternatively, the said tertiary heterocyclic bases may be reacted with a bisketene solution already prepared by the aforesaid tertiary aliphatic amine process, when adducts of the bisketene and heterocyclic base are precipitated as a hydrohalide-free adduct; this is also stable if kept dry, and may be similarly reformed into an active bisketene solution by dissolving in an inert polar solvent as before.  Examples are given for the preparation of (1), (2) and (3) cyclohexane 1,4-bisketene, and its pyridine adduct; and (4) xylylene-bis-a -methyl ketene.  The bisketenes are highly reactive, giving diesters or diamides on reaction with alcohols and amides, and reacting with the terminal -OH groups of long chain polyglycols with formation of ester end groups.
