Title: Tooth cleaning and oral hygiene agents
Inventor: GASSNER HEDWIG KIRCH
IPC: D01F6/08
Filed: 1966-03-23
Abstract: 1,137,206. Tooth pastes. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT. 23 March, 1966 [27 March, 1965], No. 12863/66. Heading A5B. A toothpaste or oral hygiene agent which inhibits the corrosion of non-lacquered aluminium tooth-paste tubes comprises a paste containing aluminium oxide and/or aluminium oxide hydrate, dicalcium phosphate (DCP), and pyrogenic silica if desired. The aluminium oxide and/or aluminium oxide hydrate occupies 1-15%, preferably 1-12% of the total mixture. If silica is also added to the paste, the ratio of silica to aluminium oxide should be almost 1:05 to 1:7, preferably 1:1. One of various compositions of paste, given as examples, is 1% binder, 59.3% water, 10.0% glycerin, 2.0% foaming agent, 1.0% scented oil, 2.5% SiO 2 , 2.2% Al 2 O 3 , 22.0% DCP. The particle sizes of the aluminium oxide or aluminium oxide hydrate are 5 to 30 mÁ and those of the pyrogenic silica 3 to 50 mÁ with a BET value of 150 to 500m<SP>2</SP>/g and a pH-value of 3.5 to 4.6.

Title: Improvements in or relating to micrometer mechanisms
IPC: G01B3/18
Filed: 1940-08-14
Abstract: 541,947. Micrometer mechanisms for theodolites &c. COOKE, TROUGHTON & SIMMS, Ltd., and TAYLOR, E. W. Aug. 14, 1940, No. 12992. [Class 97 (ii)] A micrometer mechanism for theodolites and other instruments comprises two parallel glass or like plates 9, 27 angularly movable together about a common axis V ... V, a fine reading scale 12 movable in a plane parallel to the plane of movement of the parallel plates (as by a knob 40), the fine reading scale and the plates being mechanically coupled together (as by a pin and slot connection) in such a manner that movement of the scale imparts a predetermined angular movement to the plates, the arrangement being such that light rays passing through the plates will, on angular movement thereof, be displaced to effect a displacement of image in a field of view, the displacement being proportional to the movement of the scale. As shown in connection with a theodolite, light reflected from a mirror 1 is divided between two optical systems, one system including a horizontal graduated circle 24 and the parallel plate 27, and the other system including a graduated vertical circle 5 and the parallel plate 9. After passing through the parallel plates, the light is reflected from a prism 10 to form magnified images of the circle graduations adjacent to a field lens 13 and mask 47, Fig. 6. The images, and also the graduations on the fine reading scale 12 are viewed through the eye lens 19, the graduations on the circles 5, 24 and scale 12 being observed respectively through the mask openings 48, 49, 50. In taking readings, the knob 40 is rotated until one of the graduations in the mask opening 49 coincides with its index pointer, the reading then being the sum of this graduation and the minutes indicated at the opening 50. The same procedure is then adopted in connection with the openings 48, 50.

[Class 117] A plansifter comprises a plurality of superposed sieve frames a, Figs. 3 and 4, constituting drawer-like fittings resting in shelves in the main frame and arranged in two or more superposed groups. Each sieve frame is provided with lateral apertures e by which the throughs from each sieve are passed into a collecting duct d which is provided with one or more deflector plates by which the sifted product from an upper group of sieves is directed on to a distributing tray t above the next group. The tailings from each sieve are passed by openings f to the succeeding sieve in the same group, the last sieve in which passes the tailings by an opening g to a collecting duct h at the end of the main frame. When the frame carries a series of superposed groups side by side, as shown in Fig. 3, the tailings are directed by deflectors i in the ducts h to one or more joint discharges j while the throughs are also directed to one or more joint discharge shoots r. The sieves are disposed horizontally and are of a length not more than twenty times the height to which the stock can pile on the sieves so as to enable impellers to be dispensed with. For rigidly securing the sieves in position, each sieve frame, as shown in Fig. 6, comprises two relatively movable wedges m, o by which it is securely clamped on the shelves. In a duplex machine, the sieves in the two parts of the machine are disposed in line in the direction of movement of the material over the sieves.

The current is transmitted to two of the leads of a four-core flexible cable 13 wound on a roller 12 mounted in a box 11 under the floor at the rear of the body, the other two leads being employed for the signal circuit. The connections to the cable are made by wipers 10 bearing on contact rings on the end of the drum. The signalling means preferably comprise a buzzer or a telephone ; when current is to be supplied to the X-ray apparatus, a switch is operated to disconnect the battery and signalling-apparatus in the vehicle from the signalling leads and to connect the dynamo field to them, so that the latter may be controlled by a switch adjacent the X-ray apparatus. The body of the vehicle forms a dark-room and is provided with a ruby window 18 with an external lamp fed from the car battery. Containers 20, 21 for developing and washing the negatives are provided, the upper portions 22 being forwardly-extended to form draining ledges.

Filed: 1926-05-28
Abstract: 259,502. Redfern, C. G., (American Optical Co.). May 28, 1926. Spectacle lenses.-The astigmatism inherent in the use of fused insert in a bifocal lens is overcome by grinding an optical surface on the reading lens side with a difference of astigmatic power between the reading and distance portion of the lens so that the astigmatic aberration is sufficient to compensate the original astigmatism. The other side of the lens is ground to provide the correct prescription and also the additional power necessary to balance the power added in correcting the first surface for astigmatism. The outer surface 6 of the lens is thus ground of toric form to overcome the astigmatic aberration of the segment 5 and the back of, the lens is ground to give the required prescription. The distance portion is of glass of low index of refraction and the reading portion is of glass of high index of refraction. The axis of the toric surface is positioned to neutralize the astigmatism of the reading portion. A numerical example is given in the Specification.

Abstract: 577,347. Clutches. GENERAL ELECTRIC CO., Ltd., BONEL, B., and WALLACE, D. M. Oct. 24, 1941, No. 13699. [Class 80 (ii)] [Also in Group XXXV] An external fan cooling the casing of a watertight motor is driven by the shaft but is coupled to it in such manner that if the motor becomes submerged and the torque required to drive the fan is thereby increased, the drive discontinues. In the form shown the hub 2 of the fan 3 is carried by the outer race of bearing 4 the inner race being on a sleeve secured to the shaft 1. A pawl 5 pivoted at 6 on the said sleeve has a projection 9 engaging a groove 10 in the hub 2 for transmitting the drive when the fan operates in air and the pawl is held in position by balls 7 spring-pressed into depressions in the pawl. When this spring pressure is overcome by increased torque due to the fan being immersed in water the pawl is moved out of the slot 10 and the fan drive interrupted. The pawl may be returned to the driving position as the motor slows down by movement of a pivotal weight no longer subject to centrifugal force.

In a coding and decoding circuit, key symbols S 1  and S 2  are stored in memories II and I respectively and memory III stores the plain text when coding and the cryptotext when decoding. I, II and III may also operate as a cyclic counter, shift register and modulo-two feedback shift register respectively. During coding the content of III is added modulo-two to that of memory II and is transferred into II through modulo-two circuit 5. For decoding, the content of II is added modulo-two, to that of III, the result shifted into III, again through circuit 5. The memories I, II, III are controlled by the pulse generator 10 and the divider and gates 9, 16. The shift register III, which is coupled to the memory II through the modulotwo adder 7, is operated, i.e. counts, in a direction determined by the relative lengths of the crypto symbol and symbol S 1  in II. The counter I, containing S 2  counts back to the zero or a predetermined fixed position when it stops and interrupts register III after passing through an equal number of steps.
