Title: Distillation apparatus with vacuum controlled by rate of distillate flow
IPC: C02F103/08
Filed: 1968-11-21
Abstract: In a distillation apparatus comprising evaporator 1 and condenser 2, maintained under vacuum by jet pump 10, the vacuum in the still is controlled by air-inlet valve 31 which is regulated by sensing-means 32 which measures the flow of distillate in conduit 13, whereby the rate of evaporation is maintained at a desired value. The distillate is drawn off from condenser reservoir 20 into conduit 13 by pump 15, and is directed to a storage tank (not shown) via non-return valve 29. The feed, e.g. salt water, is supplied to the evaporator 1 through conduit 5, and excess brine is drained off through conduit 9. In the embodiment shown, sensing-means 32 is a restrictive device in conduit 13, so that when the level of distillate rises to conduit 13a a signal is sent to relay 33 which causes appropriate movement of valve 31. The restrictive. device and conduit 13a may be replaced by a flow-meter. Valve 31 may also be regulated by a temperature sensing-means 35 in the inlet 11 for the heating-medium.

Title: Turntable governor drive system
IPC: G11B33/06
Filed: 1969-06-13
Abstract: In a toy gramophone 14 for a talking doll, a centrifugal governor 56 is driven from a record turntable 18 via a speed increasing planetary friction gear comprising a fixed annulus 88 coaxial with the turntable, an output sun formed by a knurled hub 90 of the governor 56, and resilient planet wheels 60, 70, 72, e.g. of rubber or vinyl, rotatably mounted on the turntable 18 and frictionally engaging the hub 90 and the annulus 88. A disc 92 retains the planets axially. The governor comprises weights 58, 60 retained by a spring 62, which move outwards to engage a fixed brake annulus 64 when the governed speed is exceeded. A drive spring 36 coiled round a drum 38 is secured at one end to the turntable periphery. Pulling a string 50 wrapped round the turntable hub 52 rotates the turntable to draw the spring 36 about the turntable periphery. On releasing the string, the turntable is rotated by the spring as it rewinds on the drum 38. A stylus 22 engages recording grooves 16 on the turntable 18 and is connected to the armature (24) of a speaker cone (26), (Fig. 1, not shown). As the string is pulled to wind the spring 36, it draws the stylus to the outer edge of the record.

Patent ES-373392-A1 (ES)
Title: Apparatus for picking grapes
IPC: A01D46/28
Filed: 1969-11-10
Abstract: Grapes are picked from a row of vines by reciprocating frames 4 carrying assemblies 1 and 2 of parallel fingers 3 horizontally (or vertically) to strike the grapes from the vines, the fingers 3 being resiliently mounted on the frame so as to move easily relative to the frame on striking an obstacle, e.g. the vine stock, so as to prevent or reduce damage to the finger 3 (and to the stock). The finger assemblies 1 and 2 pass one along each side of the vine row 10 and are staggered longitudinally (Fig. 2) or vertically (not shown), the picking machine being suspended from a row-straddling tractor. Each finger 3 projects rearwards of its frame 4 and has its rear end connected by an elastic wire or spring to the frame, each finger 3 being received in a sleeve elastically mounted on the frame alternatively, each finger 3 projects forwardly from a resilient collar on its frame 4 and comprises a cylindrical rod of resilient material. The finger 3 may have resilient tips. The detached grapes fall into a divided receptacle 8 having elastic skirts 23 and air nozzles 25, the picking machine being centered by shoes 24. Each frame 4 may be horizontally divided into three sections, the upper and lower sections being reciprocated in phase with each other but out of phase with the centre section which has twice the area of each of the upper and lower sections. Each section is reciprocated on its own rails by two double-acting hydraulic jacks which are interconnected with the jacks of the other sections and controlled by slide or solenoid valves. The fingers 3 when fully retracted have their front ends behind a grid 34 of horizontal bars, so that any stems entrained by the fingers 3 are released. A resilient lining 33 overcomes the inertia of the fingers as they start to move forwards.
Patent ES-388242-A1 (ES)
Title: Box filling apparatus
IPC: B65B25/04
Filed: 1971-02-13
Abstract: An apparatus for filling boxes with produce such as plums, apples, citrus fruit, melons, or vegetables such as potatoes, or the like, comprises an endless belt conveyor which is drive when energized by a variable electric motor at a fast or full speed until the box to be filled is substantially 95% filled and then stops momentarily after which it proceeds at a slower speed to cause a dribble feed to fill the box to substantially 100 percent of the desired weight. The momentary stop is to accommodate fruit which is freely falling, which occasionally causes the box to be substantially 100 percent filled without the necessity of the dribble feed. Associated means drives boxes to be filled to a scale, which scale has associated switches to control the stopping of the fast run of the conveyor belt, the starting of the slow run of the conveyor belt, and eventually to stop the conveyor belt and start the index motor to convey the boxes to be filled to the scale and, when filled, off of the scale. A safety switch is provided to prevent running of the conveyor in the absence of a box to be filled.

Title: Nuclear fuel rack lateral restraint
IPC: G21C19/07
Filed: 1978-03-09
Abstract: A lateral restraint device for nuclear fuel racks which can accommodate differential thermal expansion between the racks and a containing enclosure.
