Title: Pressure operated heavy duty drill head - has spring loaded stops and switches to produce automatic fast and slow feed cycle (SW 4.4.77)
Inventor: PEDDINGHAUS WERNER
IPC: B23B47/18
Filed: 1975-09-08
Abstract: The drilling head has a spindle (5) in a carriage (3) mounted on wheels (2). A hydraulic cylinder (8, 25) operates the spindle below which a rod (14) is fixed to the carriage and slides in stops on the base. Discs (15) locate springs (22, 23) which butt against each side of one stop (21)). The drill (7) advances at fast feed and contacts the work (W). This pushes the carriage rearwards (4a) to the fixed stop (17, 18). A switch (19) is energised and a time delay (26) actuates the slow feed. When relieved of pressure, as the drill breaks through, the carriage is moved forwards by the spring and a switch (20) retracts the spindle.

Title: Analysis of oil drilling samples - by two-stage heating and hydrocarbon determination
Inventor: ESPITALIE JEAN
IPC: E21B49/00
Filed: 1976-01-20
Abstract: The analysis comprises first heating the sample to vaporise the hydrocarbons present without pyrolysis of organic material, and determining the hydrocarbon content. The sample is then heated to a higher temp. to pyrolyse the insoluble organic material in the sample, and the amt. of hydrocarbons formed by pyrolysis is determined. The two results are then used to determine some characteristic of the oil-bearing formation. By plotting the two results (and/or their ratio) versus the depth from which the samples (esp. cuttings) were taken, information can be obtained about the location of matrix and reservoir rock, oil and gas zones, etc. The analysis is carried out in an appts. comprising a vertical tube surrounded by heaters at the bottom and top. The bottom heater is adjusted to give a temp. of 400 degrees C (pref. 200-400 degrees C), and the top heater gives a temp. of 400-700 degrees C (pref. 550-600 degrees C).

Title: Cleaning spray device, e.g. for paper-making screens - which includes spool valves to ensure uniform application of washing fluid (SW 17.10.77)
IPC: D21F1/32
Filed: 1976-05-25
Abstract: A spray device includes a housing which is slidable along a shaft mounted transversely to the screen. The housing is connected in the shaft to a spray head provided with apertures so that water fed to the housing falls through the apertures onto the screen. The housing is divided into two separate chambers by a centre body mounted on the shaft, and the centre body has two separate chambers to which water is fed via ducts. One chamber is closed at both ends and has a slidable spool valve, whilst the other chamber is open at both ends so that a slidable spool valve located projects from the ends of the chamber to provide end stops. When the housing is moved on the shaft the end stops hit respective ends of the housing to move the spool valve to supply water to the spray head. The other spool valve is controlled by the pressure of the water. The device is efficient and a controlled quantity of water is supplied to the spray head.

Title: Drive mechanism for loom reed, having double acting spring - with periodic frequency designed to reduce power requirements for driving reed
IPC: D03D49/60
Filed: 1976-07-26
Abstract: The reed drive mechanism of a loom includes a double acting spring arrangement arranged to have a periodic oscillation frequency which is less than the frequency of the heating up cycle executed by the reed.

Title: Continuous casting of spheroidal graphite cast iron - involves the controlled cooling of an extruded profile
Inventor: OGER JACQUES FRANCOIS
IPC: C21D5/02
Filed: 1976-12-24
Abstract: Spheroidal graphitic cast iron is cast continuously from a ladle whose outlet orifice is provided with a die imparting to the casting a desired profile of straight section. Part of the length of the profiled casting leaving the ladle is thermally insulated until it has fallen to a temperature of between 1050 degrees C and 950 degrees C. The profile is then subjected to a controlled cooling which may be accelerated, until the profile temperature is 750 degrees C. The procedure enables profiles to be obtained, without recourse to exterior heating, with good mechanical properties and having a relatively homogeneous structure.

Title: Aq. fermentation of fruits - e.g. coffee berries, cocoa beans, cola nuts etc., recycling through fermentation lock siphon after sepn. of kernels etc. (BR 19.9.78)
IPC: A23B7/10
Filed: 1977-02-24
Abstract: Pre-cleaned fruits are pumped in suspension in water into an enclosed fermenting vessel and floating fruits are discarded by surface overflow which is then closed off. The fermentation proceeds and is agitated as necessary. During fermentation the flesh of the fruits becomes hydrolysed and breaks away from the stones or kernels. Water with hydrolysed fruit flesh in suspension is drained off and the remaining kernels flushed through with water which is also drained away. The kernels are dried and prepared for sale. Fermenting fruit is pref. carried up a riser pipe by pressurised gas, e.g. CO2 from fermentation or injected air. The riser pipe delivers fruit into a receiver from which is it returned to the fermentstaoin vessel via a hydraulic fermentation lock siphon. This recycling of fruit continues for several hours. A gas pressure relief lock, pref. of the siphon type, periodically vents the vessel to atmos. so that pressure is reduced and fruit is allowed to re-enter the vessel via the fermentation lock siphon.
