Patent GB-926258-A (GB)
Title: Photographic camera
IPC: G03B19/04
Filed: 1962-03-02
Abstract: 926,258. Photographic cameras. AGFA A.G. March 2, 1962 [March 3, 1961], No. 8276/62. Class 98 (1). A camera having film-advancing means operated by an electric motor has a switch in the motor circuit actuable by the film-advancing means to break the circuit after film advance by one full frame, and a further switch in the motor circuit actuable by means other than the film-advancing means to break the circuit after a film-advancing movement has terminated, whether by a complete frame or not. In the form shown, the film is advanced by a motor 3 driven by a battery 2. After the shutter is operated to make an exposure, the switch 4 is closed to contact 5, completing the motor circuit, which advances the film by one frame, and re-sets the shutter; on completion of one film frame advance, switch 4 breaks from contact 5, closing contact 6 to short-circuit the motor. If the film were not advanced by a full frame, as might happen at the end of the film, or for some other reason such as damaged perforations, the connection of switch 4 with contact 5 would not be broken, and the battery would be rapidly discharged. Accordingly, a further switch 7, 8 is provided in series with the contact 4, 5, which in the form shown is operated by an arm 10 of the camera release lever 12, turning on a pivot 11, shown when ready to make an exposure. At this moment the contacts 7, 8 are held apart by arm 10. When release lever 12 is pressed, contacts 7, 8 are released to close together. A rack portion 15 on lever 12 engages with a pinion 16 forming part of a gear train and escapement system 26, the whole acting as a retarding mechanism. When the release lever 12 is pressed, pinion 16 rotates without entraining the rest of the mechanism, which acts to retard only the return motion of the lever. Thus contacts 7, 8 remain closed for a predetermined period while the return of lever 12 is retarded. This period is made long enough for the normal advancement of one film frame to take place. As lever 12 reaches the end of its retarded return motion, arm 10 breaks the connection between contacts 7, 8. Thus, whether the motor circuit has been broken by separation of contacts 4, 5 or not, the circuit is in any case positively broken by separating contacts 7, 8. In the arrangement of Fig. 3 (not shown), instead of a mechanical retarding mechanism, an electrical regulator is used, controlled by a governor on the motor shaft.

Title: Counting stage and synchronous counters
IPC: H03K3/037
Filed: 1975-02-27
Abstract: 1442588 Synchronous counter circuits SIEMENS AG 27 Feb 1975 [18 March 1974] 8322/75 Heading G4A Each stage of a synchronous counter comprises a clocked bi-stable element SPG arranged to implement the logic equation where Q t0  and Q t1  are the logic levels at output Q 1  of the element during first and second clock periods and S and R are the logic levels applied to the two inputs SG, RG during the first clock period, together with two majority decision circuits MD1, MD2 and inverters ND2, ND3, ND4 connected as shown. Aternatively ND3 may be omitted and MD2 connected to the inverted output Q1 of SPG; as shown MD1, MD2 have inverted outputs, otherwise ND2, ND4 can be omitted and an additional inverter inserted at RG input. The clocked bi-stable element (Fig. 1) comprises a set-reset master-slave bistable SE, MR connected to another majority decision circuit BMG (Fig. 4, not shown) as shown with feedback from the other Q to the third input E of the decision circuit. The circuit shown in Fig. 1 is for a dynamic counter. A static circuit requires an additional inverter in the feedback path to input E. In a counter (Fig. 7, not shown)the stagesare simply cascased with output ZA connected to input ZE of the next stage. With all the control inputs STG1, STG2 at zero level the counter counts up; with all the control inputs at high level (input US) and the count input at ZE1 inverted (by Exclusive-OR gate EG) the counter counts down. If a high level is applied to all control inputs STG1 only the counter is reset to zero. If a control input STG2 only is connected to high level that stage is present to logic 1; therefore to provide a divide by 10 circuit (Fig. 8, not shown) the final output of a four stage counter is connected back (through an additional clocked bi-stable element SPO) to the control inputs STG1 of the first and last stages and STG2 of the second and third stages whereby the counter is reset to a count of 6 when it overflows.

Title: Process of manufacture of an antibiotic product having specific action against the pathogenic microbes of the animal organisms, and product obtained thereby
Filed: 1953-03-22
Abstract: An antibiotic effective against a particular species of pathogenic micro-organism is produced by preparing a culture of said pathogenic micro-organism and subjecting the said culture to certain physical and/or chemical means which cause the micro-organism, while still alive, to produce an antibacterial substance which, when isolated, is toxic to that particular species of micro-organism.  The physical means are screened ultra-violet radiations, infra-red radiations, ultra-sonic radiations, X-ray microwaves or Wood's light.  The chemical means are: (a) hydrosulphites, aldehydes or peroxides which cause a variation of the redox potential of the medium and effect the bacterial respiration; and (b) sodium chloride, sodium propionate, arsenites, organo arsenious compounds, cystine and glutathione which interfere with the normal metabolism of the cells of the micro-organisms.  The antibiotic is recovered from the ozonized culture by grinding the culture with sand, adding water, stirring and filtering.  The aqueous extract so formed is concentrated in vacuo. Specified micro-organisms are Bacterium coli, Salmonella Typhi, B. paratyphus A and B, Pasteurella pestis, Vibrio cholera, Pseudomonas, Aeruginosa, Mycobacterium tuberculosis, Bacterium Anthracis, Pneumococcus, Staphylococcus aureus, Epidermophyton interdigitalis and Mycobacterium Leprae.ALSO:An antibiotic effective against the pathogenic microorganism from which it is derived (see Group IV(b)) is administered to animals including humans (a) orally e.g. pills or capsules, with or without the addition of absorbent inert materials (b) rectally in the form of a suppository and (c) parenterally. Pathogens referrd to are B. coli, Salmonella Typhi, B. paratyphus A and B, Pasteurella pestis, Vibrio cholera, Pseudomones aeruginosa, Mycobacterium tuberculosis, Bacterium anthracis, Pneumococcus, Staphylococcus aurens, Epidermophyton interdigitalis and Mycobacterium Leprae.

Title: Improvements relating to duplicating machines
Inventor: FORD RONALD MAY
IPC: B41L11/08
Filed: 1954-03-24
Abstract: 789,205. Printing surfaces. FORD, Ltd., F. R. March 21, 1955 [March 24, 1955], No. 8542/54. Class 100(2) In a duplicating machine the master sheet is secured to the printing cylinder by a clamping member 11, (Figs. 1 and 2), of strip-like form slidable radially in an axially extending slot in the face of the cylinder and being formed with cam faces 42 engaging means on the cylinder whereby when the clamping member is axially displaced it is lifted against the action of springs 38 to a releasing position so that the master sheet mav be inserted or moved. The clamping member has an angularly projecting flange 37 at the outer edge which overlies and clamps the leading edge of the master sheet against a secured part of the surface of the cylinder. The cylinder is formed by a tubular shell 22 and a pair of end-plates 23. The peripheries of the end-plates are secured and undercut to co-oprate with bevelled edges 25 of the shell 22 bolts 28 being provided to draw the end-plates together. The cylinder shaft is clamped on bosses 26 of the end-plates .The axial slot for the clamping member is formed through the shell and extended 'into the end-plates. The clamping springs 38 are connected between lugs 41 and pins 40. Where the end-plates are slotted, thickened portions 32 are provided which are formed with bores 33 to receive ball bearings 34 retained by grub-screws. The balls normally engage in U-shaped notches formed in the edge of the clamping member so that axial displacement thereof causes it to ride up into the dotted line portion of Fig. 1. A lip 43 is provided on the end of the clamping member for effecting the axial displacement, and co-operates with a thrust mmber 12 mounted on the machine frame for this purpose. As shown in Figs. 2 and 3 the member 12 is pivoted to the frame member 13 at 45 and urged in,an anticlockwise direction by a spring 52, movement being limited by a pin 53 engaging in a slot 54 in the frame member 13. A flange 47 on the member 12 intersects the path of rotation of the lip 43 so that in normal rotation (see arms 48) the lip engages the inside surface of the flange 47 and displaces the member 12 against the action of its spring. When the cylinder is rotated in a reverse direction the lip engages the edge 49 of flange 47 and is displaced axially of the cylinder to release the clamping member. A latch shoulder 50 is formed on the flange 47 so that the operator can readily bring the cylinder to the position in which the clamp is opened. Instead of being on the side frame the thrust member may be mounted on the cylinder with the flange facing towards the side frame for co-operation with a fixed abutment thereon, movement of the thrust member serving to displace and lift the clamping member.

Abstract: 541,268. De-icing aircraft. BURGESS, R. H. May 14, 1940, No. 8660. [Class 4] In the de-icing of aircraft parts the leading edge 11 of a part such as a wing, is provided with an overlying flexible skin 12 spaced therefrom and elastically connected thereto, together with means in the space there-between operable for flexing the skin. In one form a movable unit 17 is arranged in the space coacting with the inner surface of the skin, vibration of the unit being caused by obstacles in its path of movement to cause flexing of the skin and cracking of ice formed thereon. A chain of such drag link units may be used, continuous or reciprocatory movement being imparted thereto. A rail 15 provided with indentations 16 is attached to the crown of the leading edge of the wing and similar indentations 14 are provided in the skin at the same level. The drag links are provided on both sides with freely mounted balls 18, 19, and are caused to vibrate during their movement by the constant contact of the balls with the indentations. In a modification, the drag links are of arcuate section in the transverse plane and carry on their rear concave surface three parallel rows of balls co-operating with corresponding rails. The convex surfaces of the units carry similar rows of spaced rollers co-operating with the skin which in this form is without indentations The rollers may be of any suitable form such as frusto-conical. The rollers may be dispensed with, the arcuate drag links 35, Fig. 7, contacting directly on their convex sides with the skin 34 to form frictionally contacting shoes, the ice being additionally caused to be removed by melting. In another form, the system of movable units is replaced by a member of longitudinally spaced cyinders and pistons, the latter co-acting with the skin.

Filed: 1916-06-21
Abstract: 159,513. Speer, F. S. Litchfield-, and Anthony, T. June 21, 1916. Mines, marine. - Relates to automaticallyanchored mines of the kind in which the mooring- rope drum is locked by a ratchet-wheel and pawl mechanism controlled by a plummet or otherwise. According to the invention, a tooth or pawl 4 is pivoted on a pawl-lever 1 and its end 4<1> engages the ratchet-wheel 5 when the pawl lever is relieved of the pull of the plummet 2 and deflected by the spring 3. The ratchet-wheel turns the pawl about its pivot until a shoulder 4<2> on the pawl bears against an abutment on the lever 1, and at the same time the lever 1 is deflected back and thrust against a fixed stop 7. Henceforward, the locking cannot be disturbed by a pull from the plummet. Before its engagement with the ratchet-wheel, the pawl is held in position by a spring 6; and its motion in the wrong direction is prevented bv a stop 1<1> on the lever. In a modification, a. projection on the left end of the pawl is first engaged by a tooth of the ratchet wheel, and this rocks the pawl to make its end 4<1> engage, with the next tooth of the ratchet-wheel.

Title: Apparatus for removing the pile from carpets
IPC: A41H41/00
Filed: 1949-03-31
Abstract: 671,671. Removing pile from carpets &c. ARTHUR, L. E. W. March 31, 1949 [May 14, 1948], No. 8831/49. Class 42 (i). Apparatus for removing pile from carpets and the like consists of a cabinet adapted to be moved over the carpet, a hand-guided device associated with the cabinet and adapted to be moved over a limited range of the carpet independently of (i.e. without moving) the cabinet, the device being provided with pile-removing members adapted mechanically to remove the pile from the carpet, and means for operating the pile-removing members. The apparatus shown removes pile by plucking it from the carpet base, and can be used to remove pile from the edge of a piece of carpet prior to uniting it with a similarly treated piece. A hand-guided plucking device, Figs. 12, 13, comprising a housing 50, is connected by a flexible driving-shaft 40 in a hose 41, and by a flexible suction hose 20, to a wheeled cabinet, Fig. 3; the upper compartment of which houses driving and control mechanism and the lower compartment of which receives the plucked tufts of pile. Rotation of shaft 40 acts through a disc 55, crank-pin 56, a reciprocating driving- plate 57 and links 63 to cause claws 69 to close between a guide finger 74 and a guide rib 75 so as to grip a tuft of pile, and then rise to draw the tuft from the carpet. On continued rotation of shaft 40, claws 69 open to release the tuft and then descend to grip a further tuft. The released tuft is removed by suction through an opening 61 leading via a conduit 51 to one end of the suction hose 20. The other end of hose 20 communicates with a fan 19 driven by a motor 8 on the wheeled cabinet; fan 19 delivers tufts to the lower cabinet compartment. Motor 8 also drives, through a variable-speed friction drive 21, 28, a clutch shaft 30 to which an end of flexible shaft 40 is coupled. By operating a handle 38, a cam sleeve 31 on shaft 30 can be rotated against a bearing 34 to withdraw friction disc 28 from friction wheel 21 and so interrupt the drive to shaft 40. The drive can also be interrupted by a pull or jerk on shaft 40; this pulls shaft 30 outwards so that disc 28 separates from wheel 21 and a pivoted arm 42 springs between sleeve 31 and bearing 34 to keep the friction drive disengaged until arm 42 is raised again by means of a lever 49. A handwheel 39 on shaft 30 enables the plucking mechanism to be operated by hand when the power drive is disconnected. Specifications 303,913, 309,004, 337,379, [all in Class 28 (ii)], and 348,923, [Group VI], are referred to.
