Gas douches.-In order to obtain local anµsthesia, more particularlv for use in dental work, a jet of oxygen and compressed air is first heated and applied to the part to be anµsthetised and afterwards gradually cooled down to 0‹ C. The cooled jet is kept playing on the part during the operation and then it is slowly again raised to 37.5‹ C. or even 40‹ C. Compressed air is contained in the bottle A and oxygen in the bottle B. These deliver into the expansion chamber D and thence by the cock S to the chamber E. The lamp L serves to heat the jet which passes the thermometer N on its way to the nozzle H carried by adjustable bends controlled by screws Z. The heated jet cools down to about 20‹ C. owing to the draught produced by the pressure. The lamp is then turned off and cooled air at -40‹ C. is admitted from the bottle C to a reservoir projecting into the chamber E, thereby cooling it, the escaping vapour from this reservoir further cools the mixed jet. When the jet is reduced to 0‹ C., the compressed air is shut off, and the operation performed under a jet of cooled oxygen alone.

Abstract: 890,031. Separating solid materials. TEAGLE, W. T. Nov. 2, 1960 [Oct. 8, 1959], No. 34163/59. Class 117. Automatic sorting apparatus for a travelling potato harvester comprises a number of suction devices mounted for movement into pressure contact with the lifted material remaining after initial separation of the potatoes from the bulk of the soil and weeds, whereby the device act upon the relatively smooth surfaces of the potatoes to lift or deflect them out of the path of the unwanted material for separate collection. During forward travel of the harvester shown in Fig. 1 potatoes, soil &c. are lifted by a share 1 and conveyed rearwardly by a conveyer 2 to a conveyer 3 comprising spaced belts between which potatoes &c. fall to be received in an annular conveyer 4. The bulk of the tops and weeds are deposited on the ground from the conveyer 3. Potatoes &c. are then dropped on to a conveyer 5 moving forwardly, and above which is rotated a suction roller 7 comprising a number of suction devices 14, Fig. 2, each attached to the roller hub 8 by a spring clip 18. Each device consists of a corrugated rubber tube with an open mouth 16 and a closed opposite end embraced by a clip. The hub 8 comprises a spindle 11 with a number of spaced peripherally perforated discs 10 into the perforations 13 of which the ends of the clips are inserted; the mouths of the devices are close to each other and provide an almost continuous suction surface. The potatoes, having relatively smooth surfaces, are picked up and carried a short distance by the devices and dropped through a shoot 19 on to the friction surface of a rotary drum 20, and to one side of the drum. The potatoes slide down the drum in a direction opposite to its direction of rotation and are collected separately from the soil and stones &c. which is carried round with the drum and falls to the ground. Water jets 23 and 24 keep the mouths of the suction devices and the drum surface free of dirt. Instead of the hubs 8 the suction devices may be be attached to a large diameter flexible tube of the bellows type. The devices may deflect the potatoes laterally of the conveyer on to a cross-conveyer, and in this case they may be mounted on an endless belt or drum moving or rotating in a direction at right angles to the path of travel of the material.

Title: Apparatus for measuring a dimension of a body
IPC: G01B11/10
Filed: 1966-08-01
Abstract: 1,150,080. Photo-electric dimension measurement. EMHART ZURICH S.A. Aug.1, 1966 [July 30, 1965], No. 34495/66. Heading G1A. [Also in Division G4] The dimension of an object is measured by directing two parallel beams of radiation one to either end of the dimension and simultaneously photo-electrically scanning the parts of the beams not cut-off by the object to determine their width: both beams being scanned in the same direction, namely from the cut-off region to the uncutoff region or vice versa, which compensates for movement of the object in the direction of the dimension i.e. perpendicular to the beams. In one arrangement shown in Fig. 1 optical fibre light guides 18a, 18b present the uncut-off part 15a, 15b of two light beams 14a, 14b to the respective one of two photo-cells 32 positioned diametrically beneath an interposed rotating disc 22 having diametrically arranged pairs of slits Fig.2 (not shown). Simultaneous passage of a slit over each photo-cell generates a pulse from each photo-cell whose time width is indicative of the width of the uncut-off regions 15a, 15b, from which the diameter of the object 10, which may be a moving cable, can be evaluated and displayed at 38 or passed to a reject evaluation circuit 40. Any divergence of the beams is compensated by projecting them in opposing directions. Instead of a rotating disc a pair of slits may move rectilinearly, or be stationary and a moving image of beams 15a, 15b projected on to them. Mirrors or prisms may replace the optical fibres and electromagnetic radiation other than light and particle radiation may be used; the use of a laser is mentioned. By chopping the beams, intensity modulating the radiation source or introducing a grid the photocells generate a series of pulses instead of one of variable width for each passage of the slit: the number of such pulses per slit passage indicates the width of the uncut-off region 15a, 15b.
