Title: Procedure and device to control continuous crystallising machines - for crystallising and re-heating chocolate in which number of stages is reduced to 3 simplifying controls while optimising performance
Inventor: RUNGE DIETER
IPC: A23G3/02
Filed: 1990-02-14
Abstract: The process is accomplished in three stages, viz. two cooling stages and one re-heating stage. Intensive mixing and scraping of the product from the container walls is used. In the first stage the chocolate is cooled to the crystallizing temperature, and in the second it is cooled to a temperature suitable for the formation of the required number of crystals. In the third stage it is re-heated to a temperature suitable for working. In the first stage a temperature  difference between the product and the coolant of 20 to 40 degrees C is used, and in the second this difference is reduced to 6 to 14 degrees. Separate coolant circuits are used for each of the three stages, and a control system is used to regulate the coolant flow rates and temperatures in accordance with the -.  measured and required product temperatures and dwell times. USE/ADVANTAGE - This device is used in the manufacture of chocolate products, where liquid chocolate must be crystalised to a required degree for the desired texture, and then re-heated slightly to ensure workability for subsequent  manufacturing steps. The proposed system reduces the number of cooling stages needed, thus simplifying the arrangement of the controls and reducing the cost of the machine, while at the same time optimising its performance.

Title: Diaphragm valve actuator - has sleeve with coarse external and fine internal thread between hub and core
Inventor: HAAS HARTMUT
IPC: F16K31/50
Filed: 1991-01-16
Abstract: The diaphragm valve has a threaded spindle working in a tapped bore in the housing. A sleeve-type hub (2) coupled to a drive (3) turns but cannot slide in the housing (1). The spindle (5) inside the hub comprises a sleeve (6), and a core (7) which cannot turn in the housing.

Inventor: SCHOLTYSIK BERND DR
IPC: G11B23/037
Filed: 1991-02-22
Abstract: The invention relates to a flangeless stackable winding core, the intention being to avoid the inner central bore becoming compressed when a carrier of information in tape form is wound up under high winding pressure on such a core. This is achieved according to one embodiment by there being provided alongside the outer winding surface an outer core ring having a double-T profile and by there also being elastically deformable annular intermediate elements located between outer core ring and inner core ring. In the case of another embodiment, variously shaped openings or notches are provided on both sides of the winding core between outer circumference and inner circumference and are evenly distributed over the entire circumference. In addition, the winding core includes axial deformations on both sides alongside its inner circumference in order to avoid any displacing or twisting of winding cores stacked one on top of the other.

USE/ADVANTAGE - (I) are intermediates, esp. for the synthesis of reactive dyestuffs. They are prepd. using readily available Cl2 and H2O2, rather than N-chlorosuccinimide and m-chloro-perbenzoic acid, avoiding the formation of by-prods. which are difficult to separate. In an example, 709 pts.wt. Cl2 were passed into a soln. of 2204 pts. (III) in 8070 pts. dry chlorobenzene (VI) under N2 at 0 deg. C, in ca. 3 hrs. The charge was stirred for 30 mins., then excess Cl2 was expelled with dry N2. The charge was cooled to -40 deg. C, then 1680 pts. allyl chloride were added slowly at a constant rate in ca. 30 mins. Stirring was continued for 45 mins, then the charge was warmed to 20 deg. C and (VI) was distilled off in-vacuo to give 4370 pts. 1,3-dichloro-2- (phenylsulphanyl)- propane as a light yellow oil which distilled at 95 deg. C/0.2 mbar.

Title: Paper pulp solidifying process - has a suppressor shoe within first four drinier loop to contain water with further unit within second fourdrinier loop to extract water on both sides
Inventor: IWATA HIROSHI
IPC: D21F9/02
Filed: 1991-10-31
Abstract: At the stage of the papermaking machine where the pulp, from the rock inlet, is passed into the gap between two fourdriniers, a shoe or bar is within the loop of the first fourdrinier to suppress the water removal in the direction towards th first fourdrinier. A further water removal unit, close to the first shoe or bar, is within the loop of the second fourdrinier, to extract water from both sides of the wet pulp web. The pulp from the stock inlet is pinched between the two fourdriniers. A suppressor shoe, within the loop of the first fourdrinier, is near the forming roller, to prevent water from the pulp dispersing through the first fourdrinier (1). A second unit, within the loop of the second fourdrinier, directs extracted water from the pulp to both sides, using a number of projecting plates in contact with the fourdrinier. The upper sides of the plates are flat or curved convex surfaces towards the other fourdrinier. The pulp is passed over a transfer box to move into the next stage of papermaking. Water extracted from the pulp is collected for disposal.
