Title: An Improvement In or Relating to Brake Systems for Trailer Outfits
Inventor: KOUTNY ZDENEK
IPC: B60T13/40
Filed: 1967-12-15
Abstract: 1,183,869. Trailer braking systems. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. 15 Dec., 1967 [23 Dec., 1966], No. 57062/67. Heading F2F. In a compressed-air braking system for trailer vehicles having control and charging lines leading to the trailer a single air reservoir supplies both these lines through an air-flow restricting member, the ratio of the volume of the reservoir to the volume of the pipelines and spaces in the braking elements being between 15: 1 and 2:1. In Fig. 2 a small reservoir 4 is connected to a larger reservoir 7 through a member 8 which can be a throttle valve, an orifice or an overflow valve which only restricts air-flow when the pressure in reservoir 4 has fallen to a predetermined value. Under normal conditions replenishment of reservoir 7 is unimpeded but if the pressure in reservoir 4 falls due to a break in the control pipeline 6 or breakaway of the trailer sufficient braking action is obtained. In a modification (Fig. 3, not shown) the reservoir 4 is omitted; the reservoir 7 then should have a volume less than the sum of the volumes of the reservoirs of Fig. 2.

Title: Calendar timepiece
IPC: G04B27/02
Filed: 1967-12-15
Abstract: 1,140,930. Calendar timepieces. SUWA SEIKOSHA K.K. Dec.15, 1967 [Dec.15, 1966(3)], No.57100/67. Heading G3T. A calendar timepiece having day and date indicating means is provided with a setting device adjustable to a plurality of positions in one of which the device is operatively connected to a mechanism for correcting the indication of the day and date indicating means, and, when so connected, rotation of the device in one direction corrects the date indication only and rotation of the device in the opposite direction corrects the day indication only. In one embodiment the setting device comprises a crown 101 and stem, 1 adjustable manually to three axial positions. In the position illustrated in Fig. 1 a clutch wheel 6 on the stem 1 is engaged with a setting wheel 7 and a lever 3 connected to the stem 1 so engages a lever 8 that an idler gear 10 is engaged with the wheel 7 and a date correcting clutch wheel 15 meshing with a day correcting clutch wheel 17. Rotation of the stem 1 counter-clockwise, as viewed in Fig. 1, will rotate the date correcting clutch wheel 15 clockwise and a date correcting wheel 16 will rotate therewith to adjust the date ring 12. The simultaneous counter-clockwise rotation imparted to the day correcting clutch wheel 17 will not rotate the day correcting wheel 18 to rotate the day star wheel 14 to which is fixed a day dial (not shown). When, however, the setting stem is rotated clockwise the resulting counter-clockwise rotation of the clutch wheel 15 will not rotate the wheel 16 and the date ring 12, whilst the resultant clockwise rotation of the clutch wheel 17 rotates the wheels 18,14 and the day dial. When the stem 1 and the crown 101 are pulled fully out the idler wheel 10 is disengaged from the wheel 15 and engaged with the minute wheel 13, so that the crown 101 may then be rotated to set the hands of the timepiece. In a third position of the stem 1 the clutch wheel 6 is disengaged from the wheel 7 and engages with a winding pinion (not shown) so that the crown 101 may be rotated to wind the main-spring. In a further embodiment (Figs.4 and 5, not shown) rotation of a date ring and a day star wheel are so governed by spring biased jumpers that rotation of the date correcting wheel to correct the date ring causes a rotation of the day correction wheel insufficient to correct the day wheel and vice versa. In a further embodiment (Figs. 6 to 8, not shown) the date correction wheel is movable between two positions dependent upon the direction of rotation of the crown to engage either the date wheel or the day correction wheel.

Abstract: 1,144,550. Liquefaction and re-vaporization of gases. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 19 Dec., 1967, No. 57613/67. Heading F4P. Liquefied gas, e.g. natural hydrocarbon gas, having been transported in a reservoir from a production point to a consumption point, is vaporized by direct heat exchange with a cold carrier which is substantially insoluble in the L.N.G. and is of greater density, e.g. a 70: 30 water-ammonia mixture, the so-cooled carrier is then fed to the reservoir, transported to the production point and used to liquefy natural gas by direct heat exchange therewith. In operation cooling to effect liquefaction of feed natural gas occurs in three direct contact heat exchangers 12, 13, 14, Fig. 3, in series. Feed gas entering at 18 flows upwardly past trays 15 in exchanger 12 in counterflow to melted cold carrier introduced at 16 and discharged at 17, condensed impurities being withdrawn at20. The so-cooled gas enters exchanger 13 through an injection nozzle 21 and draws a mixture of granular solid and liquid carrier admitted at 24 up a capped riser 22 resulting in formation of a layer of liquid gas which is withdrawn at 23 and liquefaction of the solid carrier which is withdrawn at 26. The liquefied gas is further cooled by feeding at 30 into the bottom of an exchanger 14 and passage upwardly against downward flowing granular carrier admitted at 29 and agitated by a rotor 27. The so-cooled liquefied gas is separated from carrier at 31 and discharged at 33. Liquefied gas to be re-vaporized is admitted at 40, Fig. 4, and flows upwardly through an exchanger 34 against downward flowing powdered carrier admitted at 39 and agitated by a rotor 37. Warmed liquefied gas leaves exchanger 34 at 43 and ascends an exchanger 35 to which carrier in the liquid phase is fed at 45 and is withdrawn in the solid phase at 47. Vapour from exchanger 45 is then warmed in exchanger 36 against downward flowing carrier liquid and is withdrawn as product gas at 52.

Abstract: 1455028 Cleaning blanket cylinders; automatic control RYOBI Ltd 21 Dec 1973 59460/73 Heading B6C An automatically - operated rotary offset machine is provided with a control shaft which can set the machine in various operating positions including one in which the blanket cylinder is cleaned. In operation a control knob, Fig. 1, is manually advanced from position "0" through positions "1" and "2" engaging the various rollers and cylinders for printing to position "3" which governs the printing run. When a pre-set counter reaches zero the control knob automatically moves to position "B" for cleaning the blanker cylinder, and then to position "0" again; alternatively it is possible to move the knob from position "0" to "B" manually. The control knob is connected to a control shaft 9 carrying a cam 10 and associated index pin 11, Fig. 6; this latter figure shows the control mechanism when the knob is at position "B", rotary cam 22 continuously driving arm 23, link 24 and arm 25 while link 14 is held stationary by clutch 17. When the pre-set counter reaches zero, micro-switch 18 is energized, clutch 17 is disengaged and link 14 moves downwards under the action of spring 14<SP>11</SP> bringing disc 43 mounted on the side of link 14 into engagement with pin 26 on arm 25 and rocking arm 12 out of engagment with pin 11, Fig. 7 (not shown). Thus, on each upward movement of link 14, under the rocking action of arm 25, claw 16 mounted near the top of link 14 causes index pin 11 and hence rotary cam 10 and the control shaft 9 to move stepwise until the control knob reaches position "B" when arm 19 is pushed outwards to trip switch 21, de-energize solenoid 18, and lock the link 14. At the same time, link 35 is lowered to pivot arm 37 and release clam 29 which engages with ratchet 41; this ratchet is thereby turned through the action of cam 22, arm 23 link 24, pin 27 and arms 28 and 29 and the blanket cylinder is cleaned. When switch plate 32 on ratchet 31 trips microswitch 33, solenoid 18 is again energized. The control shaft is moved by link 14 round to position "0", the claws 29, 30 and disengaged from ratchet 31, which returns to starting position under influence of spring 56, while solenoid 18 is de-energized by microswitch (5), Fig. 9 (not shown).
