The tank is filled by connecting a pipe 22 to a tap by means of a connection 23, the tank being provided with an overflow pipe 28. When tank 26 is full a valve 31 is opened by means of handle 32 to fill the bag 10. The invalid is seated on the upper surface 13 of the bag and a valve 15 is opened to allow the bag to collapse thus lowering the invalid into the bath. On completion of bathing the invalid is seated on the collapsed bag, the valve 15 is closed and the bag is again filled with water to raise the invalid from the bath. The apparatus may be provided with a back-rest 19 attached to the bath by means of straps 20. The mechanism of valve 31 may be separated from the main part of tank 26 by a perforated partition 29 enabling the bag and piping to be stored in the said main part. In another embodiment depicted in Figs.1-4 (not shown), a bag (a) is provided with a pipe (b) which can be connected to a tap by means of an adaptor (c), a drain cock (d) being provided in pipe (b) to drain the bag (a) when it is to be collapsed.

Abstract: 1321572 Preparing and preserving meat ITT INDUSTRIES Inc (International Telephone & Telegraph Corp) 20 Jan 1972 2748/72 Headings A2D A2E and A2U Animals, e.g. hogs, are processed by a method in which, after slaughtering and evisceration, the carcases are cooled to a surface temperature of between 45 and 65‹F and divided into primal or market cuts or portions, and certain of the portions are then heated, and others are chilled. In an embodiment, hog carcases are also de-headed, split longitudinally, scalded, depilated and washed before cooling which is carried out by suspending the carcase halves from a conveyer and transporting them through a tunnel in which a flow of, first, tap water and, secondly, brine recirculated and cooled to about 32‹F is caused to flow over them. Before the cooling, the hams may be removed by knives, a chopper blade, or a rotary cutter. After cooling the carcase is divided and those portions that are to be sold fresh are wrapped in moisture-proof film and chilled in a cold air tunnel. Hams to be cured are injected with hot brine by means of hollow needles and then smoked. A second injection with hot brine, followed by pressing, may be performed. Heating without injection may also be performed by passing the needles completely through the hams and passing hot brine through them or by using electrically heated needles. Cooling may be effected by circulating cold brine through the needles. Fat cut from the carcases is passed through an apertured grinding plate by an auger and then delivered to a screw conveyer to which steam is supplied and the rendered fat delivered to a tank.

The slotted latch member 18 engageable with a U shaped keeper pivots in a plastics unit 11 and has peripheral recesses 23, 24 for engagement by the. detent member 25 which is spring urged into engagement therewith in the safety and fully latching positions respectively of the latch member which is spring urged to the releasing position. The releasing member 36 and locking member 40 pivot in a second unit 12 the units 11, 12 being secured to opposite sides of a door edge panel. The interior ends of the locking and releasing members are actuated by one arm of pivoted bell crank levers, whereas the end 40b is actuated by a key actuated lock and end 34b by external release means. The face 38 of the releasing member is displaced from the path of the detent pin 27 by actuating the locking member 40, a projection 43 of which engages in a recess of the releasing member to displace it. When the door is open the detent rests upon the periphery of the latch member and the detent pin is raised to the position 27a where it blocks clockwise movement of the releasing member 36 and therefore prevents operation of the locking member. During keyless locking, actuation of the releasing means raises the releasing member so that the pin 27 no longer blocks its rotational movement and actuating the locking member swings the releasing member to the inoperative position so that the door is locked after it is closed and the releasing member released.

Abstract: 1347720 Handling baggage SOVEX Ltd 16 Aug 1972 [31 Aug 1971] 40607/71 Heading B8A Apparatus for handling pieces of baggage, each within specified dimensions, comprises two loading stations L1, L2 at each of which a row of bags is assembled and loaded as a unit into, at L1 the bottom of a container C and at L2 the shelf of a container C. Incoming bags on their narrow sides are fed by conveyers 13 and 14 to conveyer 16, being guided by side plate 12 and pivoted plough 11. Bags on their wide side push the plough 11 aside, overbalance on the conveyer 14 to drop on to shoot 17 in the upright position and are taken by conveyer 18 to the conveyer 16. A switch section S with driven ploughs 15 feeds the bags to the required side of a pusher diverter 1 and is shown feeding the loading station L1. Fig. 9 shows the accumulation of a row of bags (from the discharge side) at the loading station L2. As each bag is fed before the pusher 1 the pusher 1 is reciprocated by a ram through a strokes lightly greater than the maximum width allowed for a bag and pushes the bag against a back plate 2 which is loaded by a return weight 25 through a freewheel 27. Successive bags are thus built up into a row, a spacer 7 being automatically incorporated in the row to prevent the associated discharge rams 4 jamming baggage against pillar 6 in the upper shelf of the container 6 when they load the row as a unit into the container. Initially a row of bags is similarly assembled at the loading station L1 and the bottom of the container C is loaded by its associated ram 4 (spacer 7 not being required for this operation). The container C is then moved across to the loading station L2, being lowered to bring its shelf into the corrrect position. The switch section S is operated so that rows of bags are built up alternately at the loading stations L1, L2.

Abstract: The 4 mA-20 mA type or 0-20 mA type current loop connects an analog sensor (1) to an acquisition system (3), respectively carrying a sensor current (Ic) and an acquisition current (Ia). A test circuit is connected in parallel with the current loop to inject a superposition current (Is) into said loop, which current is superposed on the sensor current (Ic) or on the acquisition current (Ia). In a first embodiment, a variable voltage generator (7) injects the superposition current (Is) by adding it to the acquisition current (Ia), thereby making it possible to check a low-current threshold of the acquisition system (3). In a second embodiment, a variable current regulator injects the superposition current (Is) by adding it to the sensor current (Ic), thereby making it possible to check a high-current threshold of the acquisition system. The high- and low-current thresholds of the acquisition system are tested without opening the current loop.
