Title: Method of and apparatus for inserting catamenial devices into aplicators
IPC: A61F13/20
Filed: 1944-08-16
Abstract: 594,656. Assembling catamenial tampons. FAIRWEATHER, H. G. C. (Tampax, Inc.). Aug. 16, 1944, No. 15658. [Class 81 (ii)] A method of assembling tampons of the kind disclosed in Specification 394,571. consists in creating a suction effect in the tampon applicator to draw the tampon thread into the applicator and then pressing the tampon thereinto. A suitable assembling device consists of a tubular member 24 mounted in a table 17 and formed with a tapered nozzle 26 on which the inner of the two telescoping applicator tubes is placed. An injector nozzle 38, screwed into an extrusion 33 of the tubular member and connected to a source of compressed air at 20-30 lbs. /sq. in., is formed with an air hole 40 facing downwards. The induced current of air passing through member 24 and applicator tube draws down the tampon string 14, whereupon the tampon is forced into the upper outer applicator tube (not shown). A number of these devices may be mounted along each side of the table, a conveyer belt for the tampons running along the table.

Title: Polymers containing amide groups
IPC: C08G73/14
Filed: 1970-04-02
Abstract: 1312787 Polyamide-acids VEBA-CHEMIE AG 2 April 1970 [3 April 1969] 15700/70 Heading C3R A polyamide-acid precursor for polyimide polymers is a condensate of a tri- or tetracarboxylic acid, anhydride or ester and a primary aminopolyamide containing two primary amino end groups which is the aminoamide condensate of a non-aromatic primary diamine with an aliphatic and/or cycloaliphatic dicarboxylic acid or a mixture thereof with an aromatic dicarboxylic acid. The precursors are soluble in alcohols, or in the form of ammonium or amine salts in water. The aminopolyamides may be prepared from n mols diacid and n + 1 mols diamine where n is such that there are 2 to 30 amide links in the product. Numerous suitable reactants are specified. The polymers may be used for preparing varnishes, sheet materials and moulding compositions. In Examples (1) and (4) isopropanol solutions are used to coat steel, (3) and (5) aqueous solutions of the ammonium salt are used to coat steel by brushing, spreading or electrophoresis, and (2) kaolin powder is stirred into an isopropanol solution and the slurry is dried to form a moulding compound.

Title: Frequency divider for electric waves
IPC: H03B19/12
Filed: 1927-06-13
Abstract: 296,827. Standard Telephone &. Cables, Ltd., and Reeves, A. H. June 13, 1927. Frequency, changing. -The circuit shown in Fig. 1 operates as a frequency divider, an oscillating voltage applied to the input terminals A, B reappearing at the output terminals C, D in a form that has a frequency of from one half to one-tenth its original value, according to the value of the circuit constants. The division ratio remains constant over a wide range of input frequencies. The valves 1, 2 are reciprocally coupled, the grid 3 being connected through a condenser 4 to the plate 5, whilst the grid 8 is connected through a condenser 7 to the plate 6. The plates 5 and 6 are interconnected through resistances 13, 14 in series with inductances 15, 16, a mid-point connection being taken to the high tension battery 17. The input terminal B leads to both grids through condensers 18, 19 respectively, link resistances 10 and 11 being shunted to the filaments as shown. The two valves 1, 2 may be replaced by a multi-electrode tube. An analysis of the operation is given in the Specification to show that under the influence of periodic applied voltages, the system swings between two points of stable equilibrium, the complete cycle of swing in the output taking place only once during two complete cycles of the input voltage. In addition, by adjusting the natural frequency of the circuits, the system may be made to generate free oscillations which coact with the input voltages to reduce the output frequency to one-fourth, one-sixth, &c. up to onetenth its original value. By using a cascade arrangement of thirteen such " dividers," an input radio-frequency of from 600 to 300 kilocycles may be reduced to an output frequency of from 150 to 75 cycles.

In an edge trimming machine as described in the parent Specification 1,005,576, a material detecting means 27 is incorporated to prevent transverse movement of the cutters 2 when the unsymmetrical trailing end of a length of metal strip being trimmed passes through sensing means 19, 20, 24. The material detecting means 27 is arranged in advance of the sensing means and comprises an arm 28 that is deflected about its pivot by the material (41) to operate, by cam, a switch which actuates a solenoid to open a valve (36) (Fig. 1, not shown) in the hydraulic circuit controlling the transverse movement of a carriage (4) on which the cutters 2 are mounted. When the unsymmetrical end of the material passes the material detecting means 27 and before reaching the sensing means, the arm 28 drops to a vertical position to release the switch and close valve (36) to prevent transverse movement of the cutters 2. A spring detent device holds the arm 28 in the vertical position.

Title: Improvements in or relating to underwater protective housings for photographic cameras
IPC: G03B17/08
Filed: 1954-06-03
Abstract: 783,499. Photographic cameras. HEIDECKE, R., and FRANKE, H. [trading as FRANKE & HEIDECKE, FABRIK, PHOTOGR, PRAZISIONS - APPARATE], June 3, 1954 [July 1, 1953], No. 16437/54. Class 98(1). 'In a water-tight housing for a photographic camera, a mount for one or two supplementary lenses or filters is supported within the housing on a pivot which is offset in relation to the centre of gravity of the mount, so that the latter is movable between two predetermined positions by tilting the housing. Fig. 3 shows a side view of a filter mount 18 carrying filters disposed one above the other and covering, in one position, the taking and viewfinding lenses of a reflex camera. The mount is pivoted on the pin 17 at a point on its right (looking from the front) and rests under its own weight against the stop 26. The pin 17 is carried by a bracket 9 which fits over the viewfinding lens of the camera. This bracket also carries the gears which connect the diaphragm and shutter speed setting knobs of the camera to external handles as described in Specification 783,500. One gear 20 in such a gear train has a recess 22 which in the position shown, accommodates a ball 24 which bears against a resilient arm 23. The arm 23 is fixed at one end and carries a stop 25 at its other end which in the position shown is clear of the filter mount 18 and so allows this mount to pivot in a clockwise direction (looking from the left) when the camera is tilted, until it again comes up against the stop 26, in which position the filters are removed from in front of the lenses. If, however, the gear 20 is moved, the ball 24 is forced from the recess 22 and moves the arm 23 to the left, thus inserting the stop 25 in the path of the mount. Thus the mount can be rotated by tilting the camera only when gear 20 is in the position shown, and this may correspond to the smallest diaphragm aperture setting or to the longest shutter speed setting ("T" or "B") depending on which mechanism is used. Two such mounts may be used, one controlled by each of the said camera adjusting knobs.
