Title: Improvements relating to the flushing of beer dispensing systems
IPC: B67D1/07
Filed: 1955-09-08
Abstract: 816,876. Cleaning beer-dispensing systems. AUDIA, B. Sept. 8, 1955, No. 25797/55. Class 99(2). Apparatus for flushing a coil 5 and pipes 26 of a beer dispensing system including a beer supply source 1 and a dispensing spigot 7, comprises a mixing tank 8 for storing a cleaning solution and having inlet and outlet connections, a 3-way, electromagnetically-operated valve 4 provided with inlet ports 23, 24 respectively connectible to the beer supply and the outlet connection of the tank, and an outlet port connectible to the coil and spigot, electrical control means including a switch 38 for operation of the valve to selectively connect either the tank or the beer supply to the coil and spigot, and signal means 33 associated with the spigot. As shown, a beer keg 1 is connected by a hose 3 to a compressed air tank and a pipe 2 to the port 23 of the valve 4, the port of the valve communicating by the pipe 29 with the tank 8. The latter connects via a vacuum break valve 18 and an electro-magnetically-operated valve 17 with the warm water outlet pipe 15 of an adjustable mixing valve 16 to which hot and cold water passes from pipes 12, 13. Energisation of the magnetic coil 20 of the valve 4 by operation of the switch 38 causes lifting of the plunger 21 of the coil and rocking of an arm 22 to effect closing of the port 23 and opening of the port 24 to provide flow between the pipes 29, 26. Opening of the switch causes closing of the valve 17 and the spring-assisted plunger 21 to fall to close the port 24 and open the port 23 thereby providing flow of beer between the pipes 2, 26. The cleaning solution passes through a pipe 30, an electro-magnetically-operated valve 27 and to a pipe 31 issuing into the bottom of the tank 6 which is provided with a drainage outlet 32; the valve 27 may be omitted in which case the solution flows from the coil to the spigot 7 upon opening of the latter. For automatic operation of the apparatus an electric or spring-operated timer unit may be employed and preset to operate at any particular time. A number of dispensing units may be served by a single mixing tank 8 or by separate tanks.

Abstract: 1518883 Heating IC engine intake air CUMMINS ENGINE CO Inc 29 June 1976 27088/76 Heading F1B [Also in Division F34]  Flow of fuel to the burner 34 for heating air in the engine intake manifold 36 is controlled by a metering system 40 receiving fuel at a pressure increasing as a non-linear function of engine speed from the fuel system 16 supplying the injectors 12. The system 40 operates to provide a substantially linear increase of fuel flow-rate to the burner nozzle 38 with increase of engine speed above cranking speed. The engine driven gear-pump 20 supplies fuel to a valve 22 controlled by a mechanical speed governor 26 to by-pass fuel back to the pump inlet and provide a non-linear pressure characteristic, Fig. 2 (not shown). The pressure in the passage 56 of the housing 42 is a proportion of the pressure downstream of the valve 22 determined by pressure reducing orifices 52 and 60 in a flowpath 46, 64 to the pump inlet containing a back pressure check-valve 65. A valve 68 opening at a pressure set by spring 70 having an adjustable abutment 71 opens a flow-path to the nozzle 38 via pressure reducing orifices 76 and 80. The orifice 80 is opened when the burner is to operate by a solenoid operated plate valve 86. A valve 92 opening at a higher pressure opens a further flow-path to the burner via a pressure reducing orifice 100 opening to the flow-path between the orifices 76 and 80. The opening of the valves 68 and 92 provides the desired substantially linear characteristic, Fig. 3 (not shown). A flow-path by-passing the valve 68 via a pressure reducing orifice 102 is opened by a solenoid operated plate valve 108 energized to open the flow-path below a predetermined engine cooling water temperature. The valve 86 is opened below a predetermined engine power output or intake air temperature.

Title: Improvements relating to the letting off mechanism of looms for weaving
IPC: D03D49/06
Filed: 1935-10-02
Abstract: 463,336. Loom let - off mechanism. BRADLEY, W. Oct. 2, 1935, No. 27137. [Class 142 (ii)] To enable a let-off motion of the type described in Specification 439,843 to be applied to a loom wherein the warp passes direct to the take-up roller without first passing over a movable back bearer, the warp beam is poised, suspended or otherwise freely mounted on an assembly such as brackets 3 adjustable on rails 4 carried by brackets 5. The assembly is normally held in a balanced position, the pull of the warp being counterbalanced by the thrusts of rollers 43 on rods 44 on short levers 45 on a bar 46 carrying a lever 47 acted upon by a weight 42. If the warp tension increases, a rod 48 is raised, thereby raising an arm, 49 pivoted to an arm 25 on a shaft 26 oscillated by connection with the lay. Projections 51 on the arm 49 engage a spearhead lever 52 connected by an adjustable rod 53 to a lever 54 connected to a shaft 34. Two oppositely movable e braking members 33 acting as described in Specification 439,843, are connected to a lever, which is connected to this shaft, the movement given to these members being thus varied until equilibrium between the warp pull and the force exerted by the weighted lever 47 is restored. The warp beam is lifted, as its diameter decreases by screws 6 engaging the threaded brackets 5 and rotated by bevel gearing from a ratchet wheel 31 driven by a pawl 24 on the rocking lever 25. The pawl 24 is connected by a rod 23 to a spring controlled arm 21 on a shaft carrying a warp feeler bar 18, the pawl 24 being thereby lifted from the ratchet wheel 31 when the warp beam &c. has been sufficiently raised. A crank handle 14 may be used to rotate the level gearing by hand to enable the initial warp angle to be attained. The shaft 34 is carried in bearings in a lever 35 loaded by a spring 38 &c. and also acted upon by minus springs 58, 59, which act with increasing force as the warp beam assembly rises. The members 33 are connected to a cross lever 39 pivoted on a hook mounted on a stud 40 on a bracket on the bracket 3. The stud is provided with a releasing lever 41 whereby the beam may be released from its mountings. By hand manipulation of levers 55, 56 the beam can be turned reversely or forwardly. The'arm 49 passes through an adjustable friction grip. An indicator may be attached by lever mechanism to the balanced assembly to detect any abnormal movement thereof. One beam may be suspended and another poised. According to the Provisional Specification, chain-andsprocket gearing may be used for raising and lowering the beam by hand. The brake members may be connected at one end to a cross connector rockable on one end of a link having an adjusting nut, and at the other end to opposite ends of a centrally pivoted T-lever. The two T-levers are connected by adjustable coupling members and an adjustable stop is provided behind the warp beam.
