Abstract: 990,333. Dish washing machine. PORLESTER Ltd. Jan. 14, 1964 [Jan 18, 1963; May 27, 1963], Nos. 2265/63 and 21148/63. Heading A4F. A dish washing machine comprises a casting 1 on which is movably mounted a perforated spray tube 6 supplied with washing fluid under pressure and means to drive the tube 6 to perform regular movements in two or more directions, so as to oscillate about and to reciprocate along its longitulinal central axis. Washing fluid is passed by a pump 8 through pipe 12 to a turbine 13, causing it to rotate, the fluid then passing along spray tube 6 to spray dishes in the racks 4, 5, before draining back to sump 7. The rotation of the turbine blades 15. is transmitted, via trunnion 17, crank 17a and pin 20, to a sleeve 18, attached to spray tube 6 by means of an arm with a slot 19 to create oscillatory motion of the tube 6 about its longitudinal axis. Alternatively an interconnecting element attached to two cranks by ball joints may be used to produce the oscillatory movement. The other end of tube 6 is connected, by sleeve 21, carrying a pin 22 which engages a cam surface 23a, to cam component 23, to cause the tube 6 to reciprocate as well as oscillate angularly. An alternative mechanism for producing the angular oscillation of tube 6 comprises mounting the tube co-axially with a single bladed rotor (Fig. 4 not shown) which has a to and fro movement controlled by the action of a flap valve. Specification 983,525 is referred to.

Title: Single lever control unit for marine engines
IPC: B63H21/22
Filed: 1959-01-26
Abstract: 879,083. Regulating. MORSE, J. F. Jan. 26, 1959 [May 23, 1958], No. 2731/59. Class 7(6). A control unit, e.g. for outboard motors, comprises a housing 10, Fig. 7, with a single control lever 16 connected to a throttle control arm 21, Fig. 3, and an interconnected clutch control arm 25 which are connected to throttle and clutch cables 28, 27 respectively and an auxiliary throttle mechanism 54, which can operate the throttle when the arm 16 is in a neutral (i.e. upright in Fig. 7) position. A 30 degrees movement of the arm 16, in either direction, moves the clutch arm 25 through 45 degrees via the intermittent gear plates 20, 23, to engage forward or reverse gears and the arcuate surfaces 26 engage the plate 20 to hold the clutch arm in position during further movement of the lever 16 by which the throttle lever 29, Fig. 7 is operated. A throttle cable casing 28 is carried in a mounting bushing 46 secured in a bracket 50 which swivels on a pin 51 eccentrically mounted on a plate 52 and is rotated by the auxiliary throttle lever 54. The plate 52 has detents 55A, 55B which co-operate with a spring-loaded ball 56 and plunger 57 and detent 61 so that the lever 54 can be rotated when lever 16 is in the neutral position and movement of lever 16 is prevented when lever 54 is being operated. Rotation of the plate 52 via lever 54 causes the slack in the cable casing 28 to be taken up and this produces differential movement of the cable casing and core to effect small throttle openings. The arm 21 and plate 52 may be moved through 180 degrees to employ a pulltype of throttle cable. The lever 16 may be held in the neutral position by a spring-loaded ball 63 engaging the detent in the plate 20. Excessive throttle openings in reverse or neutral are prevented by the respective levers 16 and 54 engaging the flange 11. Paired units may be mounted together with flanges 11 mating and control levers 75 turned toward each other so that they may be grasped with one hand.

Abstract: 842,588. Degasifying metals. DAUSSAN, H. . Jan. 28, 1958 [Feb. 26, 1957], No. 2792/58. Class 72 [Also in Group XXII] When casting ferrous metals the pouring jet is surrounded by a tube which is 'progressively destroyed by the metal bath in the mould which latter is closed around the tube, and a vacuum is maintained within the tube and the mould before and at the start of pouring. During subsequent pouring anc solidification the pressure of the gases emanating from the pouring jet and the meta: in the mould are regulated separately to degasify the metal, the tube forming a seal between the interior of the tube and the mould due to the delay in its destruction. A sheet metal tube 13 is sealed by an asbestos sleeve 14 to a hollow connecting head 18 clamped around the pouring opening 32, and to an annular cover 17 clamped to the mould 10. The head 18 is formed in two chambers b, c by a partition 30 having an opening 31 for the pouring jet, which opening is closable by a member 33. The mould space a, and the tube and head spaces d, b respectively are evacuable through connections 21, 40, and pressure gauges 23, 42, indicate pressures in said spaces. The bottom of the tube is initially seated on a disc 43, e.g. of fireproofed cardboard, which damps the pouring jet and floats on the melt around the tube until destroyed. The disc may also serve as a container of purifying, refining or addition products. In operation the mould and tube spaces &c. are evacuated and pouring started. The gases given off from the melt fill the vacuum and the vacuum connections are adjusted to obtain desired gas pressures, previously determined by experiment, to obtain a localization of impurities towards the centre. The pressure may also be varied, up and down, to vary the level of the melt 45 in the tube and thus obtain a stirring effect. After completion of pouring the aperture 31 may be closed by the member 33 and the mould and head assembly removed from the ladle and degasification continued during solidification. In a modification the hollow connecting head has only one chamber to which suction is applied, communicating with the mould space through perforations in the tube. In a further example the mould is bottom poured.
