The transmission (Fig. 1, not shown) is the conventional torque-converter-driven Simpson planetary gear set providing two reduced ratios, direct drive and one reverse, and the control circuit (Fig. 2, not shown), also conventional, includes 1-2 and 2-3 automatic shift valves, a manual RND21 valve, a main pressure regulator valve loaded by TV pressure subject to a cutback valve responding to governor and TV pressure to reduce line pressure at higher speeds, and a TV boost valve for processing the TV pressure applied to the shift valves. TV pressure is also increased during reverse operation, to augment line pressure, by supplying line pressure at 142 to act leftwards on a differential land of the primary TV valve 130.

The waste may be pre-comminuted or chemicalized, and fed by a seabed pipe from the shore. Treated waste is dispersed in the sea &c. or pumped ashore or into a barge or buoyant container. The apparatus may have a cover which supports navigational warning systems. In Fig. 1, two chambers are defined by flexible ballasted skirts 3 and'4 suspended from concentric rings 1 and 2, and an anchored buoy 8 is attached to ring 1 by cables 11.

Abstract: 1,033,848. Stacking-machines. SCHLOSSER & CO. G.m.b.H. Dec. 10, 1964 [July 3, 1964], No. 50226/64. Addition to 1,002,387. Heading B8C. [Also in Division B5] The apparatus described in the parent Specification (see Division B5) is modified by having a vertically reciprocable lift platform 11 which receives concrete articles from supporting board 4 when the latter is retracted to a position beneath mould 2. The lift descends by substantially the depth of the articles after each such delivery. Supporting board 4 and mould support 3 are reciprocated by a piston 6 over a vibrating table 5. The articles are transferred to the platform 11 by a vertically reciprocable stop 16, preferably hydraulically operated, and descent of the articles on to the platform is eased by providing board 4 with a bevelled end. Final removal may be facilitated by pushing a board 13 supporting a stack of articles on to a roller track 15. The stack may comprise layers interspersed with sheets of paper or the like and one layer may be angled with respect to another by rotation of the platform. Alternatively platform 11 may be suspended rather than supported in which case a conveyer may supply and/or remove boards 13.
Patent GB-1412315-A (GB)
Title: Control for container-filling machine
IPC: B65B3/30
Filed: 1973-11-02
Abstract: 1412315 Container filling machines; valve operation PNEUMATIC SCALE CORP 2 Nov 1973 50983/73 Heading B8T [Also in Division G3] A filling machine has a first valve 36 controlled by a trip valve 33 for directing pressure to a pneumatic cylinder 20 for opening a filling valve, a sensing tube 34 adjacent the filling nozzle N for sensing the level in the container being filled and to close the filling valve and a second valve 88 controlled by a trip valve 35 to isolate the circuit supplying the sensing tube before a valve 224 is opened to allow high pressure blow down air from a conduit 16 to be applied to the sensing tube. When a valve 61, Fig. 2, is operated by the trip 33 high pressure air from a supply 12 flows through passages 80 and 60 to a chamber 42 to displace a pilot valve 36 to the right where it is held by high pressure air flowing through apertures 70 and an axial passage 72. This movement of the pilot valve allows air to flow through a passage 66 to a cylinder 20 to operate the filling valve on the machine. During the filling operation low pressure sensing air flows through passages 108 and 76 from a supply 14, Fig. 1, around a valve head 91 and through a check valve 28 into a sensing tube 34. When the end of the sensing tube is closed by the rising liquid level in the container, back pressure in the tube displaces a diaphragm 116 downwardly to close a nozzle 122 fed with high pressure air to displace a valve 140 away from a nozzle 148 to move the valve 36 and shut off the high pressure air to the cylinder 20. Operation of a trip valve 107 operates a valve 88 by delivering a pulse of high pressure air to a chamber 97 to cut off the supply of air to the sensing tube and to apply blown down pressure from a conduit 16 to the sensing tube until the pressure pulse has leaked through an aperture 270 in a piston 204 and a spring 210 displaces the piston to allow a valve 224 to close. The spring loading on the valve 88 allows the valve head 91 to close before the valve 224 opens so that high pressure air cannot enter the sensing circuit leading to diaphragm 116. A valve (5, Fig. 6) is held open to vent the pilot passage 60 so long as there is no container in the filling position.

Abstract: 1522769 Mounting a spray nozzle KUROSAKI REFRACTORIES CO Ltd 16 Dec 1976 [20 April 1976] 52620/76 Heading B2L [Also in Division F4] The lining of a furnace la is repaired by spraying refractory material from a position underneath the furnace using a spraying device having a nozzle 11 on a vertically adjustable and rotatable pipe 10 carried by a transport car 8 that moves on rails 6. The pipe 10 is supported by a cylindrical body 12 that is rotatably mounted by a bearing 13 onto the car 8 and further supported by an outer frame 14. The cylindrical body 12 has elevating rollers 18 driven by a motor 19 that press against the spray pipe 10 from both sides for raising and lowering the pipe 10 and hence the spray nozzle 11. Secured to the body 12 is a worm gear 15 driven by a motor 17 that provides rotary movement to the body 12 and hence rotates the spray pipe 10 about its longitudinal axis. In a modified arrangement, a hopper body 121 (Fig. 6) is fitted round the spray pipe for collecting falling refractory material which is then discharged through a passage 133. The hopper has an observation window with a fan device 128 so that an operator can view the inside of the furnace during the repair operation.
