Title: A process of and device for cleansing, disinfecting and drying of eating and drinking crockery
IPC: A47L15/23
Filed: 1935-04-02
Abstract: 442,188. Dish - washing machines. LUTOLF, G., and LUTOLF, T., 26, Maihofstrasse, Lucerne, Switzerland. April 2, 1935, No. 10183. Convention date, April 2, 1934. [Class 138 (i)] A device for washing up crockery first sprays the plates &c. with hot soap lye and then with clean boiling water through the same jets by the operation of a multiple way valve 14. Crockery is placed in a perforated container 6. A lid 51 is removed and containers 11, &c. are filled with soapy water and hot boiling water respectively. A hand wheel 23 is set to operate a chain 21 in connection with a shaft 17 on which is a starter 16. This switches on current to a motor 56 connected to a pump 36. Lye is drawn from the container 11 by a pipe 35 through a channel 33 of the multiple valve 14 thence through a pipe 37 by a channel 38 to a conduit 40 to jets 43 and through a branch conduit 45 to jets 50. The cross pipes 42, 49 rotate in known manner to spray the plates &c. The lye collects above a partition 5 and passes through a valve 63 opened by a cam 19 to a pipe 65 into a filter 27 and back into the container 11. When the plates are clean the hand wheel 23 is rotated 60‹. This stops the motor. The valve 63 is closed by the cam 19 and a valve 63<1> is opened by a cam 18. Consequently in this new position of the multiple valve the following occur. The pump draws hot fresh water from a second container behind the container 11 by the pipe 35 through the passage 33 and conduit 61 thence through the delivery pipe 37, passage 38 by another conduit to the conduit 40 and so to the jets. After this water has sprayed the plates and cleaned off the fatty substances arising from the lye spraying, the same collects above the steel partition 5 and arrives in the large container 13 through the open valve 63<1> and pipe 62. When the water in the container 12 is used, which would be indicated by a float, the hand wheel 23 is again rotated 60‹ whereby the motor is again switched off. If it be desired to empty the whole device, the hand wheel is rotated another 60‹ whereupon the motor restarts, the suction pipe 35 draws the lye out of the container 11 by the channel 33, pipe 32<1> and draws the water from the container 13 if the valve 75 is opened. The delivery pipe 37 of the pump forces this liquid through the valve channel 38 into the pipe 70 whereupon the same can be caught and lead farther at 71. Reference has been directed by the Comptroller to Specifications 238,313, 255,396, and 290,285, [all in Class 138 (i)].

Four-stroke-cycle engines; cylinders, varying clearance of.-A cylinder head, in the form of a sliding piston, is automatically adjusted so that a maximum compression pressure in the cylinder is never exceeded. The sliding piston 11 is adjusted by an annular screw-threaded member 15 which is rotated through a rack 64 and pinion 52 and a worm 51 by the difference of pressures acting on pistons 56, 57 carried by the rack rod 53; the piston 56 is subjected fluid pressure acting through a pipe 59 or the pressure of a spring 55 having an adjustable abutment 98; the piston 57 is subjected to the cylinder compression pressure acting through passages 60, 72 when. a valve 61 is opened by the engine, and when this pressure execeeds the pressure acting on the piston 56, the pistons 56, 57 move and the piston 11 is lifted. At ignition the valve 61 closes the connections 60; later it opens a. connection 73 leading to the induction pipe when the pistons 56, 57 fall. A connection to a speed governor 83 reduces the degree of opening of the valve 61 as the speed increases. Separate control pistons may be provided for each cylinder of a multicylinder engine, and in the over-head valve engine shown the cam-shaft 27 is divided into separate sections for each cylinder, the sections being connected by flexible couplings, and driven by a vertical shaft having a telescopic joint. If one pair of control pistons 56, 57 only is provided for the engine the connection 73 is omitted and the piston 11 does not then move during the cycle. The application to side valve and sleeve valve engines is also described, and in these cases the cylinder head is rotated on a fixed screwthread to adjust the clearance.

Abstract: 942, 742. Fluid pressure servomotor control systems. CHELTENHAM AUTO CONTROLS Ltd. March 24, 1960 [April 1, 1959], No. 11134/59. Heading G3P. [Also in Division B1] The supply of compressed air through a line 14 Fig. 1 and a throttle valve 15 to an intermittentblast producing means 12 for severe flow cleaning of gas filter bags 3 is controlled by unseating a normally closed valve 54 Fig. 3 between a compressed air supply line 24 and a chamber 57 open to line 14; said valve 54 being controlled by means responsive to the difference between the pressure drop across the filter and an adjustable reference pressure. Opposite sides of the filter bags 3 are connected by lines 19, 20 to opposite sides of the movable end wall 39 of a bellows 40 to which is secured a spindle 38 carrying diaphragms 25-28, 30 spaced by sleeves 41. The upper end of spindle 38 when displaced upwardly serves to throttle an adjustable nozzle 34 connected by a line 35 Fig. 2, a chamber 48 and a restrictor 49 to the inlet connection 50 of the compressed air supply line 24. The diaphragms 27, 30 carried by the lower end of spindle 38 forms the chamber 47 which is connected through a line 23 to the reference pressure unit 22. Diaphragms 26, 27, 30 form vented chambers 32 and diaphragms 26, 28, 30 form spindle control chambers 66, 68. In operation and when spindle 38 is urged upwardly by the pressure drop against the action of the reference pressure in chamber 47,the spindle obstructs nozzle 34 to cause a pressure build-up in chamber 48 which in turn depresses diaphragm 29 to open a normally closed booster valve 54 to allow access of compressed air from line 24 into a chamber 57 and thence through a union 58 into the line 14 leading to the blast producing means 12 which is constructed as described in Specification 922,281. Air pressure from chamber 57 also passes to spindle control chambers 66, 68 the diaphragms 30 of which being of greater area than diaphragm 28 tend to displace the spindle in opposite directions thus exerting a stabilizing effect. When a filter cleaning period the pressure drop falls sufficiently to allow the bellows plate to assume its normal retracted position, pressure in line 35 falls to a value at which valve 54 becomes seated and the air supply to line 14 is cut off.
