Title: High frequency medical drip feed pump - has sealing valve downstream of electromagnetically operated pumping piston
IPC: F04B43/09
Filed: 1976-01-12
Abstract: The medical drip feed pump has an approximately L-shaped piston with its tip resting on the liquid supply tube, and which can oscillate about a pivot point so that the tip compresses and releases the tube to deliver liquid. The piston is rocked at high frequency by an electromagnet above. This is followed by a sealing device downstream. This consists of a spring loaded plunger with an enlarged head whose top face slopes upwards to form a tip which can compress the supply tube. This acts as a block when the pump is not operating but the plunger is pushed back by the pressure of liquid passing through. A resilient strip is mounted above the tube opposite the pressure point of the tip.

Title: Checking surface condensers for cooling water leaks - using sample collection from tube plate and testing for salts
Inventor: GARDEY ROBERT
IPC: G01M3/02
Filed: 1976-11-18
Abstract: Poor sealing on tubes in surface condensers with expanded tubes held in tube plates is traced by taking a small stream of vapour from the main flow and allowing it to flow down the inside of the tube plate. Here is condenses and is drained off. It is then analysed for impurities. If this contains no impurities, it can be refed into the system otherwise it is discharged to drain. The system works by having a baffle at a distance from the tube plate, through which the tubes pass and which has clearances from the tubes. Condensate running down the inside surface of the tube plate is then checked for dissolved solids which would indicate a leak. Used on power station surface condensers where cooling water contamination of boiler feed is deleterious.

Title: Light-guiding glass filaments contg. germanium dioxide - in combination with oxides of other elements (NL 4.10.77)
IPC: C03C13/04
Filed: 1977-04-04
Abstract: Light-guiding glass filaments are produced by depositing alight-transmitting material from the gas phase onto the inner side of a glass tube which does not contribute to the light transmission; then effecting collapse of the tube and drawing the resulting composite filament until the required construction is attained. This process is improved by using as a light-transmitting material GeO2 (50-99 wt.%) with not 1 additive. Filaments have low light loss; relatively large aperture (>0.25) and high light transmission capacity. The index of refraction nD >=1.55; it increases inwards. The gradient of the index of refraction is parabolic; the exponent is 1.7-2.1. The additives are pref. cpds. of P, B, Ti, Ta, Nb, Sn, Zn, Zr, Al, La, Sb and/or As. PRef. the mixt. contains 1-50 wt.% of Sb2O3, P2O5 and/or ZnO. The deposit pref. contains two zones; there is no refraction gradient in the outer zone.

Title: Reference colour recognition device - has filters to select reference colour and compare intensity with preset level
Inventor: PLEYBER GAETAN
IPC: G01J3/51
Filed: 1977-09-02
Abstract: The colour recognition device for detecting a reference colour in colour printing, or detecting coloured indicators uses a filtering method. The first optical filter (F1) receives the light emitted by the object and has a transmission band in the wavelength of interest. A second optical filter (F2) selects a band not including the wavelength of interest. Detectors (C1, C2) measure the two outputs from these filters, and the difference between them is found. The difference signal is then compared with a present value to determine the presence of the reference colour of light.
Patent FR-2363439-A1 (FR)
IPC: B41F13/60
Filed: 1977-09-07
Abstract: The folder comprises a combined grooving, tucker blade and gathering cylinder (1), a cutting cylinder (3) and a folding cylinder (5). The incoming web of paper can be cut up selectively into whole sheets or half sheets. If it is not cut up into sheets, as in normal operation, but into half sheets, the first half sheet is gripped by the gathering cylinder (1) and passed on to the folding cylinder (5) and delivered by the latter into a spider wheel (21). In contrast, the second half sheet is gripped only briefly by the cutting cylinder (3) and delivered to a spider wheel (31). The folder has the advantage that the half sheets produced are delivered alternately at two different places so that there is a sufficient gap between two half sheets in each case, thus guaranteeing reliable operation of the delivery device, and that it is suitable with comparatively little additional expenditure both for normal production and for production with half-size sheets.
