Class 69 (ii) [Also in Group V] A package sealing machine comprises a frame, relatively movable jaws mounted thereon, mechanism for closing the jaws comprising a main operating device, linkage connecting said operating device to said jaws, an auxiliary operating device connected to said linkage to close said jaws initially a hydraulic pumping system having an inlet and return passage, a starting valve controlling communication between the said passages and means for selectively actuating said valve to connected said passages to cause liquid to circulate substantially free of pressure or to cause liquid to be forced under pressure to said auxiliary device having means comprising a passage normally closed by the auxiliary device but openable thereby at a predetermined point in the jaw closing operation to supply pressure to the main operating device. The machine comprises a frame 1 having a main cylinder bore 33 containing a piston 32 under pressure of a spring 34 adjustable by a screwed sleeve 35, and an auxiliary cylinder 24 containing a spring pressed piston 23 connected to thrust links 20 pivoted to a link 18 at 19. One end of the link 18 pivots at 17 on a link 14 pivoted to a movable jaw 10 by a pin 15 which may be inserted in any one of a plurality of holes 12 in the jaw 10. The opposite end of the link 18 is pivoted at 26 to a crank 27 pivoted at 28 to the frame 1 and having a roller 30 engaging the piston 32, the crank being connected to the frame 1 by a spring 36. The jaw 10 turns on a shaft 3 to which is also pivoted a jaw 4 adjustably secured to the frame 1 by a pin 9 which may be inserted in any one of a plurality of holes 7 in the jaw 4. An electric motor 45 drives a pump 38 in a reservoir 37 to supply liquid to a duct 56. The outer ends of the cylinders 24, 33 are connected by a return duct 37a. Communication between the duct 56 and a return passage 53 is controlled by a spring pressed valve 50 held open or permitted to close by an actuating rod 54 biased to open the valve by a spring 55. Two plates 72, 73 secured together by straps 74 are pivoted to the frame I at 77 and act as a guard for the jaws and as an actuator for a switch 71 which controls a solenoid connected through links 68, 63 to a lever 65 pivoted to the frame 1 at 66. The link 63 is formed with teeth 62 which engage under a head 61 on the actuator 54 which is raised by the teeth when the solenoid is energised. A detent 85 drops under the head 61 to hold the actuator in the raised position. A duct 57 connects the cylinders 24, 33 and is controlled by the piston 23. An adjustable needle valve 90 operates in a duct 92 between the passage 57 and a passage 93 which communicates with a cylinder containing a piston which when sufficient pressure liquid has passed the valve 90 rises and contacts a finger 99 on the link 65 which withdraws the detent 85 and the actuator 54 reopens the valve 50. Specification 623,016 is referred to.

Filed: 1929-05-18
Abstract: 329,172. Henderson & Co., Ltd., J. M., and Medd, R. T. May 18, 1929. Overhead transporters. -An aerial cableway of the kind having a supporting cable, a traversing rope and a hoisting rope, has the hoisting rope passed over a jockey pulley which is adjusted in position .by a motor controlled by changes in tension of the hoisting rope so that the skip travels horizontally independently of the load. The hoisting rope e is anchored to a pulley block i on the trolly c and is reeved between the pulley block i and fall block i<1> and passes round a pulley i<2> on the mast a, a jockey pulley j and a pulley k to the hoisting drum of winch g. The jockey pulley j is connected by an adjusting rope l passing round a pulley m to the drum of an adjusting winch n driven by a motor q. The spindle o<2> of the pulley m is mounted in bearings o, the spindle bearing against compression springs o'. The spindle is connected to one arm of a pivoted bent lever p, the other arm of which is adapted to engage contacts or switches in the control circuit of the motor q. In operation, when the skip is loaded, the increase in tension in the hoisting rope and therefore in the adjusting rope l moves the pulley m and operates the bent lever p to complete the control circuit of the motor q of the adjusting winch n so that sufficiemt hoisting rope is taken up to compensate for the increased sag of the supporting cable. The adjusting motor may be put out of action when required by a cut-out or dashpot. The control circuit of the adjusting motor may include limit switches operated by the adjusting winch and which break the circuit when the winch has coiled or uncoiled enough rope to compensate for the difference in length of the hoisting rope at the charging and discharging positions.

Patent GB-1022624-A (GB)
Title: Improvements in or relating to the production of alcohol-reduced beer and other beverages
IPC: C12C/
Filed: 1963-04-22
Abstract: After a process of removing alcohol from beer by partial evaporation in a vacuum chamber (see Division B1) in which the beer is preferably evaporated to 60-80% of its original volume, a hop decoction with water or thinned wort may be added to the dealcoholized beer in order to bring it back to its original volume and impart a hop flavour to it.  The liquid to be added may be adjusted to a pH value of 4.5-5 by addition of a small amount of lactic acid wort or of lactic or citric acid. Subsequently, the diluted beer is recarbonized to 1% CO2, and is then passed into a storage tank.  Here, the bung-pressure is slowly decreased so that some of the CO2 is released, which removes volatile, disagreeable-smelling substances from the beer.  In order to avoid oxidation during the dealcoholization, the partial evaporation of the beer may be carried out in the presence of living yeast, in which case the dealcoholized beer is heated for a short time to about 60-70  DEG C. prior to its further treatment, so that vitamins leave the yeast cells and enter the beer.  The beer may be subjected to a final treatment with absorbing agents, e.g. silica gel, bentonite or active charcoal, in order to stabilize albumen.

Title: Nuclear well logging method
Inventor: SCHERBATSKOY SERGE A
IPC: G01V5/10
Filed: 1959-05-11
Abstract: 917,685. Neutron well-logging. PERFORATING GUNS ATLAS CORPORATION. May 11, 1959, No. 16024/59. Class 40 (3). Apparatus for distinguishing between water and oil bearing strata in well-logging is arranged to detect sodium or chlorine frequently present in salts dissolved in subterranean water but much scarcer in oil. To this end the logging instrument 13 includes a neutron source 15 proviiing fast neutrons of about 5 MEV., a neutron detector 17 and a gamma-ray detector 16. The detectors are suitably shielded from direct radiation from the source and are coupled to recording apparatus at the bore-head. Detector 16 is surrounded by a lead or tungsten filter dimensioned to strongly attenuate gammarays of less than 2 MEV. and to favour rays with energies of the order of 7 MEV. Neutron detector 17 has a shield 20 of nickel or magnesium which attenuates fast neutrons and transmits best neutrons having energies below 10 EV. This shield is preferably mounted outside the instrument case so as to displace some of the slow-neutron attenuating well fluid which would otherwise lie in the path of the neutrons returning from the bore wall. Additionally two further sensitive elements are provided in the legging instrument. One of these is a gamma-ray detector 25 spaced from the neutronsource so as to measure only gamma radiation naturally emanating from the bore and the other gives a pulse output each time it passes a collar joint in the bore lining. The output of all the detectors is amplified and fed to the surface to operate signal intensity meters controlling the production of a composite record. On this a depth scale 68 is produced by the collar detection signals and a record 67 of natural gamma radiation. Trace 65 indicates the intensity of the neutron rays reaching detector 17 and trace 66 the intensity of gamma rays falling on detector 16. Gamma rays resulting from neutron capture by both sodium and chlorine have energies in the neighbourhood of 7 MEV. and thus the presence of these elements results in a greater signal output from detector 16. Further these elements have large capture cross-sections for neutrons and so a reduced number of returned neutrons will reach detector 17 when they are present. To accentuate the effect caused by sodium and chlorine the output of detectors 16 and 17 can be combined in a ratio determining meter or their difference used to give a single trace. In another arrangement the ratio of the outputs of detectors 16 and 17 is applied to a further ratio measuring device in conjunction with the output of detector 25 to give a single composite trace.
