Abstract: 947,620. Couplings for core drills. CRAELIUS CO. Ltd. Dec. 6, 1962 [Dec. 6, 1961], No. 43678/61. Heading F2U. A core drill 19 is driven by an adapter 10 through an intermediate annular member 14, the inner portion of which is screwed on to the adapter shank 12 so that rotation causes an' outer conical surface 15 on the member 14 to be wedged against a complementary surface 17 on a split tapered sleeve 18 in the end of the drill, or against such a surface formed in the end of the drill itself. A liquid sealing disc 21 is secured between the end of the drill 19 and a flange 13 on adapter 10, but this may be omitted in the case of a small diameter drill, the end of the latter then engaging directly with the flange 13, Fig. 3 (not shown).

Title: Devices for projecting projectiles to effect the administering of drugs, medicines and the like to animals
IPC: A61D7/00
Filed: 1962-11-20
Abstract: 1,017,495. Firearms for administering drugs &c. to animals. C. A. MURDOCK. Nov. 20, 1962 [Nov. 24, 1961; Aug. 13, 1962], No. 43874/62. Heading F3C. A firearm for the projection of a projectile, e.g. a hypodermic syringe, for the administering of drugs, medicines &c. to animals situated at a distance from or unapproachable by the administering person, is designed to produce a minimum of noise of discharge. According to the invention a charge loading means and a charge chamber housing are secured to a supporting stock, and a gas expansion chamber is provided communicating with the charge chamber and the barrel such that when a charge is in the charge chamber and a projectile in the barrel and a firing mechanism actuated, the explosion gases pass from the charge chamber to the gas expansion chamber and thence to the barrel to project the projectile. The gas expansion chamber is provided with baffles for reducing the noise of discharge and with a gas expansion control means for controlling range and velocity of projectile. In one form, Fig. 2, the gases pass from the charge chamber 6a through a passage 9 to the rear end 11a of a duct 11 located in the gas expansion chamber formed by a housing 7. The gases pass along the duct 11 to the forward end of the expansion chamber and then back past baffles 12 to a port 13 leading to the rear end of the barrel 10 behind the projectile (not shown). The gas expansion control means comprises a cylinder 15 mounted in front of the housing 7 and separated therefrom by a vlave housing 16 having a valve 17a urged against its seat 17b by a spring 18c secured to a valve rod 18b slidably held in a screwed cap 18a in the forward end of the cylinder 15. By adjusting the cap 18a, the spacing between the valve 17a and its seat 17b can be varied to vary in effect the capacity of the expansion chamber, and thus to control velocity and range of the projectile. In another form Fig. 4 (not shown), the gases pass from the charge chamber 6a via a passage 9 to the forward end of an annular expansion chamber 7a surrounding the rear end portion of the barrel 10. The gaess then pass rearwardly past baffles 12 to the rear open ends of the chamber 7a and barrel 10a. These open ends are covered by a breech cap 24 shaped to guide the gases into the rear end of the barrel. The control means for the expansion chamber is a cylinder 15 which forms in effect an extension of the chamber 7a, the cylinder 15 having a piston 25 slidably but non-rotatably mounted therein, the position of the piston 25 being adjustable by means of a screwed rod and cap 18, 18a to vary the effective volume of the expansion chamber.

In a first arrangement the intensity of an uncollimated light beam transmitted through the cell to provide a spot of light of picture element size is varied. In a second arrangement a collimated light beam is transmitted through the cell, and is thereby modulated across its width due to the delay line characteristics of the cell. Each image line is immobilized by pulsing the light source at line frequency, and an oscillatory mirror provides the frame scan. The light source may be a laser or incoherent white source and a neoprene attenuator is provided at the end of the cell opposite the transducer.

Patent GB-1005245-A (GB)
Title: Improvements in or relating to electrophotographic materials
IPC: G03G5/087
Filed: 1961-12-14
Abstract: The photosensitivity of photo-conductive zinc oxide powder which is to be incorporated in electro-photographic material is modified by treating the powder surface with a Lewis acid so that the Lewis acid combines with at least 10% of the surface area of the oxide particles. The Lewis acid should not be a dye and should be stronger than zinc oxide.  Treatment in accordance with the invention not only modifies the photo-sensitivity of the oxide but aids the adsorption of many dyestuff sensitizers otherwise only slightly or inappreciably adsorbed. Electro-photographic materials can be made by slurrying the zinc oxide in an inert solvent such as toluene or xylene and adding with violent agitation the predetermined quantity of Lewis acid dissolved in a relatively small amount of an inert solvent such as acetonitrile, dimethylformamide, methanol, or toluene.  A solution of a sensitizing dye may be added, a solution of a resinous binder is added, and the mixture coated on to a support and dried.  If the Lewis acid is a gas or may be readily obtained as a vapour, perhaps in an inert carrier gas, dry oxide powder can be treated, and this then dye sensitized and used to form electro-photographic coatings in conventional ways.  Lewis acids mentioned in the Specification are hydrofluoric, hydrochloric, hydrobromic, sulphuric, phosphoric, tri-fluoroacetic, iodoacetic, sulphamic and thioglycolic acids, hydrogen sulphide, boron tri-fluoride, cyanuric chloride, maleic anhydride, sulphur dioxide, zinc chloride, zinc bromide, silicon tetrachloride, acid chlorides and bromides such as acetyl chloride, acetyl bromide, benzoyl chloride, adipyl chloride, adipyl bromide, and iso- and tere-phthalyl chlorides, and chlorosilanes such as methyltrichlorosilane, dimethyldichlorosilane, trimethylchlorosilane, phenyltrichlorosilane, phenyldimethylchlorosilane, and diphenylmethylchlorosilane. Dyestuff sensitizers exemplified belong to the cyanine, di- and tri-phenyl methane, azo, thiazine, oxazine, azine, nitro, anthraquinone, phthalein, thiazole and acridine classes, but any dyestuff can be used.  In electro-photographic materials, the support may be of paper or may be a conducting support formed, for example, from a metal foil laminated to a paper base. The photo-conductive layer has a zinc oxide to binder ratio of between 0.5-6 parts oxide to 1 part binder, the binder being an organic polymer such as a cellulose ester, a copolymer of styrene and butadiene, polystyrene, polyvinylchloride, a polyvinylacetal, poly-n-butyl-methacrylate, a polyolefin, a polyester, or a polycarbonate.

The web, fed into a loop 33 by rollers 32 is pulled intermittently through a stamping, printing or numbering machine 7 at the varying velocity by a gripper 8. The feed device 6 comprises a constantly rotatable perforated drum either with fixed radial walls (26), (27) Fig. 6 (not shown), defining a chamber in which the vacuum can be altered, or with a movable mask (23), Fig. 4 (not shown), for controlling the vacuum applied to the web, control in either case being via a cam-shaft 10. The printing member 2, dancer roll 5 and gripper 8 are all driven by the shaft 10 such that when the gripper 8 feeds a length of web, the vacuum effect in the feed device 6 is low so that the web is not fed thereby and the slack is taken up by the rising dancer roll 5. The vacuum effect is then increased to advance the web at constant speed through the printing station as printing takes place, the dancer roller descending during this operation. A web clamp may be provided downstream of the gripper 8. Flexo-printing, letterpress and web offset printing may be undertaken.
