Suction is supplied to individual suction chambers 331 through respective longitudinal passages 301 in the shaft and a valve arrangement disconnects the suction to the chambers when they are located within a predetermined range of their rotational movement. In one embodiment, Figs. 7 and 8 (not shown), suction is supplied to a chamber (353) in a stationary boss (351) which is coupled to an end of the shaft 55a/56a. The boss (351) includes a valve member (354) engaging the end face of the shaft to close in turn the longitudinal passages 301 which open into the boss vacuum chamber (353) at said end face. In a second embodiment, Fig. 2, the longitudinal passages 301 communicate with respective control channels 302, each of which extends around part only of the shaft periphery and is isolated from the other channels by O-rings 303/323. The channels 302 have the same peripheral length but the ends of each channel are angularly staggered in relation to the respective ends of the other channels, Figs. 3-6, (not shown). The compartment suction chambers 331 are connected to a suction source when the channels 302 are so angularly positioned to be in communication with respective passages 312 in a support bearing member 58/59 for the shaft 55a/56a. The revolver may have four, six, eight, twelve or sixteen compartments and is constructed of lightweight material.

Abstract: 1,254,708. Analysis; chromatography. TECHNICON CORP. 26 Nov., 1968 [29 Nov., 1967], No. 56138/68. Heading B1X. [Also in Division G1] An analytical apparatus for continuously treating a flowing stream, e.g. of protein, for chemical analysis comprises a liquid chromatography system and a colorimeter which is used as an analyzer and incorporates a gas segment detector to provide a signal to shut down the apparatus if liquid flow in the apparatus falls below or rises above the normal value, thus protecting the apparatus from possible damage. Fig. 2 illustrates a suitable colorimeter arrangement in which effluent from a chromatography column mixed with colour producing reagents and segmentised by gas segments is passed through passageway 110 in colorimeter 100, and peristaltic pump 104 is adjusted so that it pumps out only liquid through passages 106+116 for analysis, and gas out through leg 122. If the flow is normal only liquid will pass. out through tube 128 past bubble detector flow cell 130. If the flow rate in passage 110 drops below normal, air will be aspirated back from impedance 132 past detector 130, which will provide a signal which can be used to shut down the system. If a higher proportion of the inlet fluid passing into passage 110 is gas, e.g. due to the operation of the valve in Fig. 1 (not shown) caused by an increase in liquid pressure, a portion of this gas will pass round bend 126 into passage 128 and hence flow past detector 130 to also cause a shut down of the system. The gas segment detector is shown in Fig. 3. The bubble or gas segment detector of Fig. 2 and valve of Fig. 1 can be used in a system as at 100, Fig. 5, and at 580 and 582 respectively, for automatically sequentially loading and analyzing a plurality of pairs of samples, one column 502 being used to separate out acid and neutral components, and the other column 504 to separate out basic components. A sample supply device 506, similar to that taught in Specification No. 1,178,382 is used to intermittently and successively provide pairs of identical samples to the pair of columns. The chemistry of the analysis is described in Specification 1,204,816. Sources of solutions for column 502 are at 538, 560, 562, 564, and for column 504 at 567. Products from columns 502, 504 meet sequentially a nitrogen segmentized ninhydrin hydrazine stream at points A and B respectively and pass through colorimeter-gas segment detector 100 which is as shown in Fig. 2. Should an over pressure situation develope in either of the pump 508-column 502 or pumps 510- column 504 circuits, the respective valve 580 or 582 will open and divert the respective eluent stream. Such a system will eventually develop bubbles or gas segments at the gas segment detector 130 to halt the system.

In an electric dry shaver comprising a movable cutter reciprocable relatively to a stationary cutter and a cutter drive member in driving engagement with cutter operating means provided at one end of the rotatable drive shaft of a motor, the cutter drive member has a first movable surface provided with a cutter actuating arm engaging the movable cutter and movable upon operation of the cutter operating means to reciprocate the movable cutter and has a second movable surface connected in driving relationship with the cutter operating means and movable thereby in a direction opposite to that of the first surface. The cutter drive member shown comprises three surfaces 55, 56 and 57 each formed on the opposite ends thereof with flexible supporting legs 58 and 59 connected at their extremities by straight edge portions 60 mounted in recessed bearing portions 48 of the wall 24 of the casing 20. A cutter drive arm 61 is provided on each surface 55, 56, 57 and engages the loop portion of a leaf spring 40 which urges movable inner cutter 39 against stationary outer cutter 38. The cutter operating means comprises an eccentric pin 67 which projects from a block 69 to which is connected an eccentric pin 68 formed on the end of the drive shaft 27 of motor 26, the pins 67, 68 being 180 degrees out of phase. The surfaces 55 and 57 are connected by an insert member 65. When the motor 26 is operated, the pin 67 drives the surface 56 and its cutter 39 in one direction while the pin 68 drives the surfaces 55 and 57 and their cutters 39 in the opposite direction. The underside of the surface 56 may be provided with a weighted member. In a modification, the cutter operating means comprises a pair of detachably-mounted pinion gears (101, 102, Figs. 8 to 13) each mounting an eccentric pin (95) and a drive gear (105) meshing with the pinion gears and mounting an eccentric pin (95) which is 180 degrees out of phase with the pins on the pinion gears. Upon operation of the motor (26), the pinion gears drive the outer movable surfaces (85, 87) of the drive member (80) and their associated cutters (39) in one direction and the drive gear drives the inner movable surface (86) of the drive member and its cutter in the opposite direction. In another modification, the drive member (112, Figs. 14 to 18) comprises a strip member (113) and a counterweight member (120) which is disposed below the strip member, one eccentric pin (67) of the cutter operating means being in driving engagement with the strip member and the other eccentric pin (68) being in driving engagment with the counterweight member whereby when the motor (26) is operated, the strip member and the inner cutters are moved in one direction and the counterweight member is moved in the opposite direction.

Abstract: 1,156,360. Hydraulic shock absorbers. L. S. SUOZZO. 18 Dec., 1967 [27 March, 1967], No. 57421/67. Heading F2S. [Also in Division F1] An hydraulic shock absorber, for supporting equipment such as piping which must be free to move slowly (e.g. as a result of temperature changes) but prevented from sudden movement, consists of a piston-cylinder unit H connected to a valve unit V which is in turn connected to an accumulator unit (not shown, but see Division F1). The piston-cylinder unit has a piston 20 whose rod 22 passes through an inner sealed bearing 23 and an outer bearing 53 which wipes the piston-rod and so keeps that part of it which may enter the cylinder free from dirt. Within the cylinder are two Bellville springs 28, 30 which serve as end stops. Displacement of the piston effects flow of fluid from one side of the piston head 20 to the other by an external path through the valve unit V, and this unit communicates by way of conduit 65 to the accumulator. The valve unit is such as to allow slow flow of fluid through it but to prevent rapid flow.
