Title: Prefabricated reinforced circular silo - formed from segmental panels above each other with joints cast-in
IPC: E04H7/28
Filed: 1974-06-11
Abstract: Prefabricated panels for the construction of silos, cheap to manufacture and to make the erection of the silo quick and simple, are reinforced and made of any kind of expanded material. Each panel comprises two concentric cylindrical segments (1, 2) and has in each of its lateral radial walls a groove delimited by surfaces parallel to the axis of the silo. One of its lower faces has a tenon and the opposite face a matching mortice. The panel is reinforced by means of two layers of reinforcement bars, the first ones being parallel to the axis and the second ones forming circular arches centred on this axis. The panels are assembled in horizontal rings one on top of the other so that the cavities formed in each ring by the end grooves are aligned vertically. These cavities form vertical shutters into which protrude the circular arched reinforcement bars.

Title: Joining two metal sections as concrete formwork traverse - with slit-interval-defining projection on spacer with limiting stop
IPC: E04G17/04
Filed: 1974-08-05
Abstract: The metal shaped-sections to be joined, in concrete forms with shuttering supported on longitudinal carriers, in turn supported on the other side by the traverses made from the sections, are parallel to each other at an interval apart. The projection which determines the interval slit width between the sections is on a spacer unit which also carries the stops limiting their movement towards the shuttering. Detachable connections, pref. U-shackles, are also fitted on the spacer for pressing the sections against the sides of the projection and against the stops, which are pref. flat surfaces with the sections fitting closely against them. With the spacers the shaped sections can be accurately joined without elaborate appliances, and special lengths can be easily prepared, and then used again in standard lengths.

Title: Continuous mixing of sugar syrup of constant density - automatically controlled by measuring density before solids dissolve
IPC: B01F3/08
Filed: 1975-04-24
Abstract: A first liquid is mixed with an added ingredient in the form of a solid material or a second liquid of different density. A constant vol. of mixture is maintained in a vessel into which the rate of flow of the first liquid is regulated by a vessel level control. The ingredient is added continuously and thoroughly mixed into the first liquid, the charged vessel being weighed continuously to give a measure of the density of the mixture which is used to regulate the rate of feed of the ingredient and thereby adjust the density automatically to a control value. Mixing is pref. effected by pumping the first liquid into the vessel via submerged ejector tube mixers. Final mixture can be drawn off from the vessel by a pump of which the delivery rate can be adjusted to suit mixing the either by means of throtting or by an adjustable speed drive. The density is accurately controlled, i.e. to within 0.1 % accuracy, before the ingredient is fully mixed in and before a solids ingredient is dissolved. No need to wait until mixture is drawn off to check density.

Title: Continuous veneer dryer with double belt - speed of feed conveyor controlled by action of double belts on veneer
IPC: F26B25/02
Filed: 1975-06-24
Abstract: Band dryer for continuous veneering consists of a carrier belt (2) and a cover belt (3) between which is a controlled speed difference.

Title: Synthetic feldspar prepd. from kaolin and metal hydroxide - and its use in agglomerating organic and mineral particles
Inventor: DAVIDOVITS JOSEPH
IPC: C01B33/26
Filed: 1976-02-20
Abstract: Synthetic feldspars are prepd. by mixing a thermally activated kaolin and a conc. soln. of metal hydroxide under conditions which give a reaction mixt. in the form of a semi-dry powder, which is prevented from heating. The reaction mixt. is then compressed mechanically, the compression being maintained during the start of, and throughout, the exothermic reaction, the temp. increased to >=100 degrees C. Pref. the process can be accelerated by initially heating the compressed reaction mixt. to >=50 degrees C to initiate the exothermic reaction. If the metal hydroxide is NaOH, a hydrated feldspar is obtained which is like a synthetic zeolite type A. The speed of the reaction is high and the process can be used both to make synthetic feldspars comparable to those obtained by the much slower digestion and crystallisation techniques.

It can be fixed in place on the corner of a piece of joinery etc. by the adhesive and finally secured by hooks or points on the wall covered by the lip fitting in the channel. The second lip forms the seal, being compressed against the moving portion.

Title: Control system for hydrocarbon hydroconversion processes - monitoring process parameters and regulating hydrogen/hydrocarbon mole ratio
IPC: C10G49/26
Filed: 1976-07-30
Abstract: The hydrogen/hydrocarbon mole ratio is continuous, hydrogen-consuming, hydrocarbon hydroconversion processes, is controlled by employing analyser to monitor composition characteristics of the charge stock of the liquid reaction effluent and the hydrogen concentration of the vapour phase introduced into the reaction zone, and transmitting representative output signals to comparator/computer means which generate additional comparator output signals which are then utilised in the control system for regulating the H2/hydrocarbon ratio. The technique is applicable to processes in which the reaction zone effluent is separated into liquid and hydrogen-rich vapour phases, a portion of the later being recycled in the reaction zone. The method compensates rapidly for changes in charge stock characteristics and operating parameters and maintains catalyst activity and stability.
