The left-hand side of the figure shows the caravan in its collapsed position, the right-hand side in the extended position. The caravan comprises side walls 1, at least a portion of each of which can be rocked into a horizontal plane, and vertically-movable roof supports 4 mounted in guides 5 in the underframe, and on which rests a rigid roof 3, flexible material 6 being stretched over the outer edges of the side walls and roof supports when extended. The material may be held in the positions 7 and 13 by stays 8 connected by a rod 9. The stays may be (a) pivoted at 11 to the supports 4 so as to move the material automatically into and out of position 7 when the roof is moved vertically ; (b) extensible to hold the material in position 13 ; and (c) disengaged at the pivots 11 and connected at points 12 so as to occupy horizontal positions in which they are held by cables and support luggage or a bed at each side. Primarily, the lowered side walls 1 provide sleeping accommodation and also serve as benches for a table 15 which is foldable about a longitudinal axis. The raising and lowering of the roof and swinging of the side walls may be effected separately by hand or simultaneously by means of cables 19 each of which is secured to a roof support 4, e.g., at pivot 11, passing over a roller 16 secured to a guide 5, and is then attached at 17 to the adjacent side wall 1. Springs 18 in the guides 5 counterbalance the movements. Further cables 19b connected to a common shaft 20 operable, e.g.. by a removable crank 21 and lockable in any position, may also be used. In a modification, the roller 16 is mounted on the rigid roof part 3. End walls between the guides 5 are formed as doors which may support cooking appliances. The upper parts of the fabric form an inclined roof and additional fabrics may be secured at 28 to the rigid roof part 3 and to the ends of spring-controlled, extensible stays 8 to form a double roof. The draw-bar for the caravan is fitted into a longitudinal pipe 27 having a series of holes through which transverse bolts &c. may be passed so that the projecting length of the bar may be varied or it may be removed and used as a tool. Tubular spring-pulled feet are provided at the corners of the caravan and contain holes through which bolts can be passed adapted to bear against the bottom of the vehicle.

Title: Improvements in pulsators
IPC: A01J5/12
Filed: 1947-03-31
Abstract: 624,484. Cow milkers. SVENSKA AKTIEBOLAGET GASACCUMULATOR. March 31, 1947, Nos. 8656 and 8657. Convention dates, April 1, 1946 and Feb. 28, 1947. [Class 84] In a pulsator having a body in which move two mechanically coupled valves under the control of a diaphragm, the low pressure source is connected to a passage 15 leading to a teat cup through chamber 11, past valve 4 and through passage 18, whilst the vacuum is applied to a diaphragm chamber 10 through passage 17. At the same time a passage 16 leading to the other teat cup is connected to atmosphere by way of chamber 14, past valve 6 to chamber 12. The diaphragm chamber 9 is connected to the passage 16 by way of passage 21, the labyrinth passage 20 and passages 18, 19. The passage 20 delays the build-up of the pressure differential on the diaphragm 7 owing to the frictional resistance offered to the passage of the air by this labyrinth passage. At a given pressure differential the valves move downwards reversing the pressures on the teat cup passages and causing the cycle of operations to reverse. The rate of pulsations is determined by varying the cross-sectional area of the labyrinth passage by squeezing a resilient closure member 22 into the channel 20. Specification 334,146, [Class 84], is referred to.

Title: Improvements in or relating to the control of forced-flow, once-through boilers
IPC: F22G5/20
Filed: 1958-03-20
Abstract: 884,132. Forced-flow steam boilers; superheaters. DURRWERKE A.G. March 20, 1958 [March 20, 1957], No. 8928/58. Classes 123(2) and 123(3) A forced-flow, once-through boiler comprising economizers 2, 3, evaporating surfaces 4, 5 and primary, secondary and final superheaters 6, 7, 8 has a control heating surface 32 connected in parallel with the economizers 2, 3 and located in the path of the combustion gases from the boiler furnace, the flow of working medium through the control surface being held constant by the automatic adjustment of a valve 33 in accordance with variations of the pressure difference across a flow resistance 42 in the control surface outlet connection. The working fluid temperature as it flows through the surface 32 is measured at points 43, 44 and the temperature difference which, since the flow of working medium is constant is indicative of the heating value of the furnace gases, is applied in the form of a control signal to a main fuel controller 13, this signal anticipating those derived from changes in steam outlet pressure and temperature caused by fluctuation in the rate of fuel supply or in its calorific value and thus allowing the boiler firing rate to be more quickly adjusted to the new conditions. The steam temperature is regulated by two spray-type attemperators 20, 21 inserted respectively before the superheaters 7, 8. The water flows to the attemperators 20, 21 are respectively controlled according to measures of steam temperature at the outlets of the superheaters 7, 8. A working fluid by-pass 50 is provided for the evaporating surface 4, the amount of working fluid flowing in the by-pass being controlled according to measures of steam temperature and pressure at the outlet of the surface 5 to maintain a small degree of superheat at the said outlet and so ensure that the transition zone is always located in the heating surface 5. In operation, a master controller 11 controlling a feedwater regulator 9, the main fuel controller 13 and a combustion air control means 15 is set so that the boiler yields the desired output pressure throughout its load range. The steam temperature is automatically regulated by the attemperators 20, 21 and the heating capabilities of the furnace gases are maintained by signals derived from the heating surface 32.

Title: Circuit arrangement for private automatic branch exchanges
IPC: H04Q3/62
Filed: 1950-04-12
Abstract: 675,894. Automatic exchange systems. MIX & GENEST AKT.-GES. April 12, 1950 [April 12, 1949; April 12, 1949], No. 9016/50. Class 40 (iv). In a P.A.B.X. of the type in which incoming calls are handled by an extension acting as a master station and in which interim connections may be set up between extensions while an incoming call is held over an exchange line, a manually adjustable switch is provided by which master station status may be given to any desired extension, the selected extension then being rung, in the event of an incoming call, over the path used for the interim connections. In the embodiment six extensions and one exchange line are provided. Incoming ringing current over the exchange line operates relay AR and relay A1 follows to bring up HR which locks, and to energize the thermal delay relay Th1. Switch S1 is set manually to the arc contact corresponding to the extension to be made the master station and over its wiper the relays An and Rf of that extension are operated. In the case shown, the master station is extension 1 and it is thus connected to the interim connection circuit. Relay A1 connects a ringing generator to this circuit and when extension 1 replies RU pulls up to the loop. HR is thus released and Th1 open-circuited. Relay Rf restores at once but An being slow-to-release remains up until the operation of relay A (which follows the release of Rf) completes a holding circuit for it. Relay A also switches the exchange line through to extension 1. To transfer the incoming call to another extension, say No. 6, the ground key (not shown) at extension 1 is operated to operate differential relay X in the feed circuit. Relay U1 (not shown) follows in known manner to transfer extension 1 from the exchange line to the interim connection circuit and to hold the exchange line. Extension 1 then sets up the interim connection and then replaces his receiver to effect the connection of the incoming call to extension 6. Automatic transfer of incoming calls to auxiliary master station. If the master station selected by the switch S1 fails to answer within a predetermined time the thermal-delay relay Thl pulls up and is followed by relay W which locks up and transfers the operating ground from S1 to a second manual switch S2 set to a second extension which is then called by operation of its relays An and Rf. For night service working this feature is disabled by setting S1 and S2 to the same extension.
