Abstract: 646,091. Moulding-machines and processes. LIPS, M. M. H. April 12, 1948, No. 10115. Convention date, April 10, 1947. [Class 83 (i)] A method of making a mould for casting a propeller designed for operating in liquid in which the mould comprises a lower and an upper section for each propeller blade and in which at least on one of said lower sections the propeller blade model is shaped or positioned, the upper mould sections being formed on said lower section and model, is characterized in that one complete lower mould section with a loose counter-mould thereon is first made and then a further lower mould section is formed against the said counter-mould. A floor 16 of moulding material is built up on a concrete floor 6, the upper face of the floor 16 being given the form of a helix by means of a strickle 1 co-operating with a pitch guide 5. A blade mould 21 having a cavity 23 is arranged on the floor 16 to form a complete lower mould section. A loose matrix or counter-mould 25 is then built up by hand on the complete lower mould section. The matrix is then raised and displaced in the direction of the arrow 27 until it reaches the position of the second propeller blade when it is lowered on to the floor 6. The hollow space of the matrix is then rammed with moulding material which forms the lower mould section for the second propeller blade. After this, a propeller blade model 30 is modelled by hand on the first complete lower mould section and the upper mould section is formed thereon. A wooden or metal blade model may be used instead of a modelled blade model.

Title: Vapor Compression Distillation Apparatus and Method
IPC: C02F1/04
Filed: 1978-07-18
Abstract: A vapor compression distillation apparatus and method are provided wherein scaling tendencies are eliminated. The raw feedwater has acid added to it in an amount sufficient to convert the carbonates and/or bicarbonates therein to carbon dioxide. The heated acidified feedwater is then deaerated at 15 to remove the carbon dioxide and other non-condensible gases. The deaerated water flows to the evaporator 10 through a line 30 having a valve 32 therein controlled by the liquid level in the deaerator to maintain such level constant even though the tube side of the evaporator is being operated at a pressure less than that of the deaerator. This permits the evaporation to take place under a partial vacuum and at a boiling temperature of less than 212 DEG F even though the deaerator is operated at atmospheric pressure. Vent steam from the evaporator is added to the deaerator to further preheat the feedwater, and as a sparging or stripping agent to aid in the elimination of carbon dioxide and other non-condensible gases. <IMAGE>

Title: Detecting tampering of kilowatt-hour meters
IPC: G01R21/00
Filed: 1979-01-11
Abstract: To detect tampering of a kilowatt-hour meter by the connection of a bypass link across the live connection through the meter, a voltage transformer within the meter unit is coupled to this live connecton so that a small volage is induced in the live connection in opposition to the supply voltage. The induced voltage produces a circulating current in the loop formed by the live connection and the bypass link and the transformer coupling is such that, with a bypass link of negligible resistance, the total current in the live connection is in opposite phase to the applied voltage. By means of a current transformer, a logic unit and a microprocessor, the phase of the current in the live connection within the meter is determined and is indicated by a latched flag indicator and/or transmitted to a distant data processor by a data link. Using a second current transformer in the return supply lead, the supply and return currents in the leads within the meter unit can be compared in the logic unit and processor to determine if the live connection is broken within the bypassed length. By means of contacts on the housing, indication is given if the housing of the unit has been opened.

Patent GB-2082221-A (GB)
Title: Fence Erecting Machine
IPC: E04H17/26
Filed: 1979-04-06
Abstract: The machine has been designed to secure a fencing post into the ground by making use of hydraulic, mechanical, or pneumatic power supplied by the prime mover to which it is attached. This is done by transferring the weight of the machine on to the top of a post until there is insufficient weight left to give any further reaction. At this point a hammering device gives a series of rapid blows on the top of the post as a weight is lifted by a powered cam and against a heavy spring which adds to the "hammering" power. The machine has further been designed to place a wire/wires, netting, or sheeting alongside this post; and where more than one wire is used, to apply equal tension to the wire/s through a slip clutch/s which connect the drive shaft/s carrying a reel/s of wire, netting or sheeting to a suitable power source on the prime mover. The spacing between the wires can be predetermined as required by means of spacer rollers which can be pre-set and over which the wires pass. The drive through the slip clutches allows the wires, netting or sheeting to be re-wound. A clamp attached to the frame of the machine allows the posts to be recovered. <IMAGE>

Title: A roller for vehicle wheel cleaning machines
IPC: B60S3/04
Filed: 1979-05-29
Abstract: A roller on which vehicle wheels are spun to throw off dirt centrifugally has an internal automatic lock/unlocking device that is operated when the roller is rotated briefly in the reverse direction by engaging the vehicle reverse gear. A non-rotary vertically- sliding latch 6 is held in an unlocked position by detents and drops into a locking position under its own weight when the detents are overcome. When locked the latch lies in the path of a ramp 15 on the roller internal circumference that has a steep face 16 that encounters the latch when the roller is rotated forwardly and a sloping face 17 that cams the latch into the unlocked position when the roller is reversedly rotated. To overcome the detents spring-urged bolt 10 is cammed into engagement with the latch 6 by a ramp 14 mounted on a ring 19 inside the roller which is arranged to free wheel when the roller rotates forwardly so that the latch is only operated when the roller rotates reversedly. A switch inside the roller is operated to signal the roller locked or unlocked condition.   <IMAGE>
Patent GB-2022554-A (GB)
Title: Crude oil sampling
IPC: G01N1/12
Filed: 1979-06-18
Abstract: A method for collecting a crude oil sample in a natural reservoir to maintain a monophasic condition of the sample consists of pre-pressurising mercury in a mercury chamber with a gas and automatically admitting the mercury under the influence of the gas to the sample chamber on closure thereof in the reservoir. A sampling device has an elongate longitudinally shiftable control rod (23A,B) extending through a generally tubular assembly incorporating sample, gas (52) and mercury chambers (53), and a clockwork delay-action mechanism. The rod is hydraulically released from a "primed" condition of the sampling device and thereupon shifts to close the sample chamber. A further hydraulic release allows opening of a valve to admit the mercury under pressure into the sample chamber. Pressure in the sample chamber is maintained above "bubble point" of the sample by mercury entering and reducing the volumetric capacity of the sample chamber thus to compensate for the net thermal effect on the sample of a temperature drop on retrieval of the sampling device from the reservoir. <IMAGE>

Title: Improvements in or relating to automatic locking electrical socket outlets
IPC: H01R13/453
Filed: 1979-08-22
Abstract: An automatic locking outlet is provided for use as an electric mains wall socket. The socket comprises a front plate 1 and a slider 3, each of which has formed therein holes 9 for the passage of pins of a mains plug. The slider 3 is slidable from a first position, in which it covers the outlet holes (as shown), to a second position, in which the slider holes and outlet holes are aligned by pushing with the plug pins against the action of a spring 7. Two spring-loaded slidable locking pins 12 enter the holes in the slider 3 when in the first position to lock it in this position. When a plug is inserted, the pins thereof push the locking pins out of the hole to allow the slider 3 to be moved to its second position and the plug pins to enter the outlet holes. When no plug is inserted, there is no access to the outlet holes, thus improving the safety of the outlet. <IMAGE>

Title: Compensating for Variations of the Oxygen Sensor Output in Automotive Exhaust Emission Control System
IPC: F02D41/14
Filed: 1979-11-23
Abstract: In a closed loop exhaust emission feedback control system, air-fuel mixture is maintained at a stoichiometric ratio under the influence of an oxygen sensor in the exhaust. The voltage produced by the sensor however falls as the sensor ages, and any given voltage represents a richer mixture than that predicted by the original characteristic curve of the sensor. According to the invention, the sensor voltage is repeatedly measured when the air-fuel mixture is rich, when the sensor voltage is a maximum, and if any decay takes place, the normal closed loop control is compensated accordingly. The rich mixture may be produced specially for the measurements (that is, interfering with the normal running of the car), during an acceleration, or by noting the peaks of the fluctuating signal produced due to cylinder-to-cylinder variations in a carburettor system where such variation is encountered.
