Title: Crumbling and statically unsound sandstone buildings reinforcement - by washing, rinsing and injecting stabilising solution at alternating temps.
IPC: E04H9/16
Filed: 1974-10-30
Abstract: The process is for strengthening historically valuable or other buildings of sandstone showing signs of deterioration, esp. calcium-carbonate-bonded sandstone, preventing further decay and restoring adequate static load bearing capacity, and proceeding in varying day and night temperatures or using heat sources if necessary. The stone is first thoroughly washed in a fluid constantly flowing over it, in peridocially fluctuating temperatures; the capillaries are rinsed, and it is then continually sprayed with, or otherwise subjected to, a reinforcing solution until the fluid and the solution have attained a predetermined concentration. Foil coverings may be used to check air access and promote temperature differences. The reinforcing solution may be a mixture of saturated silicic acid solution and saturated limewater. Pref. the fluctuating temps. are produced by hot air heating as required.

Title: Transportable conveyor for stacking tanned skins - skins monitored during transfer, lifted by suction and stacked correctly
IPC: C14B1/62
Filed: 1974-12-13
Abstract: A stacker for tanned hides has a first conveyor transferring the processed skins from a prior treatment stage to a second conveyor. This consists of a number of parallel belts fitted with suckers, the bores of which move along a corresponding row of holes in the lower wall of a vacuum chamber connected to an exhaust pump by a duct. This can be closed by a programming device controlled by a minotor such as a photo-electric cell, signalling both the presence of the skin and its length, on the first conveyor, and determining the exact point in time at which the skin is dropped on the stack. A series of plates or rails inside the vacuum chamber may be used to close the bores and effect the dropping of the skin. Cuts out repeated and expensive hand operations.

Title: Optical sensor system - tends to maintain picture in central position using cylindrical lens focussing it in line
IPC: G02B27/00
Filed: 1975-07-09
Abstract: A sensor is provided whose electric output signal changes when the picture line moves from a specified central position. A servo system varies the relative position of the line and the sensor, depending on the sensor output signal, so that the line is maintained in the central position. The sensor responds to the line position outside its central position owing to a change of the part of the sensor sensitive area exposed to the picture. The sensor is provided with two sensitive areas, one of which is symmetrical with respect to the picture central position, and the other receives the picture line light only when the line is on one side of its central position.

Title: Electric steam iron - has steam chambers and thermal mountins to prevent droplet spray and temp. loss
IPC: D06F75/26
Filed: 1975-11-07
Abstract: In a domestic electric steam iron, the water supply is fed by a rubber ball in the hand grip, with a main steam chamber located in the ironing base plate with thick metal layers, conducting heat from the ironing base plate to the chamber. The steam follows labyrinth paths on either side with a number of heated surfaces. A lower steam chamber, has two connecting apertures, to the main chamber the lower chamber being sealed by a removable thermal conductive plate which is an insert in the ironing base plate and acts as part of the ironing surface. A regulating valve is composed of a valve stem and a pliable section coupled to the auxiliary steam unit for control of the steam through controlled water supply. The design prevents water droplets from spraying out of the iron, and also prevents loss of temp. at the ironing surface through conversion of water drops into steam.

Patent FR-2336543-A1 (FR)
Title: Tunnelling shield able to negotiate unstable sections - injects filling material behind ring of lining segments using resilient seals
IPC: E21D9/08
Filed: 1976-12-21
Abstract: A tunnelling machine which after the tunnel has been cut, allows lining segments to be attached to the sides, and which allows filling material to be injected in the gap behind the segments, is advanced hydraulically, and modifies the lining procedure when an unstable region is encountered. The process of positioning the segments is interrupted until a further stable region is met again. In the meantime, either quick setting cement or timbering is used with the segments already installed to reinforce the sides. The water pressure of the hydraulic drive for the machine is used to stabilise the unstable zone as the machine passes through. To inject the filling material, the machine uses a flexible sealing ring immediately behind the tunnelling shield, which contacts the ring of segments and another sealing ring to contain the filling material.
