Title: High speed dental handpiece
IPC: A61C1/14
Filed: 1957-12-19
Abstract: 829,892. Dental handpieces. TANNER, P. H., and NAGEL, O. P. Dec. 19, 1957, No. 39503/57. Class 81 (2). A dental handpiece comprises a handle at the working end of which is a casing insertable in the patient's mouth and a fluid driven means in the casing to receive, hold and rotate a dental tool. A brass or copper rotor 16 is housed in a stainless steel casing 15 forming the head of the handpiece. The rota has buckets in the form of semi-circular indentations or may have conventional vanes. The rotor has a reduced portion 22, for receiving the shaft of a dental burr, and a burr holder 19 by which it is mounted in bearings 17, 18. Neoprene or rubber rings 20 in the rotor secure the butt. The casing is detachably secured to a handle 14 which houses a compressed air supply pipe 35, a discharge tube 31 directing the air through the casing and against the rotor. Expansion of the compressed air in the vicinity of the rotor cools the dental burr. After use, the air supplied passes through slots 29, 34 in the casing and the handle respectively, to the rear of the handpiece and escapes to atmosphere through muffler material 54 and holes 52 in a muffler holder 45. The compressed air is supplied through a flexible hose to the rear of the handpiece which has a hoseguard 46 and an adaptor 43 which is connected with the supply pipe 35.

Patent GB-950822-A (GB)
Title: Improvements in and relating to photographic projection printing apparatus
Inventor: WOODCOCK EDWARD CECIL
IPC: G03B21/11
Filed: 1958-12-09
Abstract: 950,822. Copying apparatus. WILLIAMSON MANUFACTURING CO. Ltd. March 9, 1960 [Dec. 9, 1958], No. 39731/58. Heading G2A. A photographic projection printing apparatus comprises an observation screen outside the path of projection on to the paper, a minor system which can be moved from a position in which the image is thrown on the printing paper to a position in which it redirects the beam on to the observation screen, the disposition of the minor system and observation screen being correlated so that the observation screen occupies an equivalent optical position to the paper, and an automatic focusing adjustment. Light from a source 13 is focused on to a negative placed at 15 and is then directed by a rotatable mirror 19 and one of two mirrors 23, 25 on to an observation screen 24 or printing paper at 26. The mirror system and the objective lens 18 are each mounted on supports which are slidable vertically on a plate 12 for automatic focusing. The two supports are operatively connected by means of a cam and follower or rack and pinion. The rotation of the mirror 19 is effected by a Bowden cable which also effects the exposure by aid of a foot switch. When the mirror rotates into the exposure position it may close an electric switch which increases the intensity of the source 13 temporarily. The printing paper is fed from one cassette over a roller 43 (Fig. 4) through a channel 26 to the take up magazine. The feed may be automatically effected by the exposure control mechanism which gives an impulse to a solenoid 51 which closes a switch 53 of an electric motor and removes a stop 48 from a disc 47 which is rotated once by the motor. During the rotation it (a) moves a rack 56 to and fro which movement is transmitted through a one way clutch to the roller 63 the amount rotation of which, and therefore the amount of paper fed, is controlled by an adjustable stop, (b) it moves the rod 91 to and fro, the forward movement of which serves to tension a spring on the take up cassette. This spring is then allowed to run down freely and rotate the cassette to take up the paper. The rotating disc 47 may also be used to operate mechanisms for stamping a number &c. on the paper and partially severing it. The paper may be completely severed by operating the guillotine manually. Shutter flaps 111, 112 may be provided between mirror 19 and 23, 25 and controlled by the Bowden cable mentioned above. In a modification shown in Fig.8 the mirror 19 may be replaced by two mirrors 19a, 19b, which are movable into either of the two positions shown by dotted lines. In the position shown by full lines light from the negative may be allowed to reach a photo-electric device (not shown).

Title: Stabilized hydrogen peroxide
IPC: C01B15/037
Filed: 1959-11-30
Abstract: Hydrogen peroxide is stabilized by the addition of a minor proportion of a water soluble carbocyclic compound the molecule of which possesses a saturated carbocyclic ring system having at least two carbon atoms that are adjacent to one another and are directly linked to N(RCOOM)2 groups; R being an alkylene group containing 1 or 2 carbon atoms; M being a cation.  The carbocyclic ring system may be a single, saturated hydrocarbon ring containing 4-9 carbon atoms or a fused ring structure containing 7-20 carbon atoms.  R is preferably a methylene group as for example in the preferred compound 1,2-diaamino cyclohexane N,N1-tetraacetic acid.  The carbocyclic compound may be in the acid form, i.e. M being hydrogen, or in the salt form, M being ammonium, alkaline earth metal, aluminium or zinc or any cation giving a salt which is inert to peroxide particularly a monovalent cation, e.g. an alkali metal ion.  The compound may also be part in the acid and part in the salt form.  The carbocyclic ring system may also be substituted by other groups, e.g. halogen, alkyl, carbonyl, or carboxyl groups which in turn may also be substited for example by hydroxy, keto, aldehyde, ether, acid or ester groups.  The amount of carbocyclic compound employed varies between 1-1000 milligrams preferably between 3-250 milligrams per litre of hydrogen peroxide solution and may be employed in addition to known stabilizers, e.g. pyrophosphates, stannates or nitrates.  The Specification contains numerous examples of the stabilizers of the invention.
