Title: Enzymatic isomerisation of glucose using ano
IPC: C12N1/38
Filed: 1970-04-13
Abstract: In a culture of micro-organisms of the genus Streptomyces, able to assimilate xylane under formation of glucose-isomerase, the organism is cultured in stages in aqueous nutrient medium under submerged aerobic conditions whereby in at least one initial stage a small amount of water-dispersible non-nutrient material is incorporated, which causes fibrous growth of the micro-organism. The non- nutrient material is pref. used in the first two growth stages of the culturing process. The micro-organism is pref. Streptomyces wedmorensis ATCC 21175 or Strep. ATCC 21176. The non-nutrients used are agar at 0.005-0.25% pref. 0.2% carboxymethylcellulose at 0.1-2% or diatomaceous earth at ca 4%. The glucose-isomerase produced is used for the isomerisation of glucose to fructose in syrups used in the foodstuff industry. The additional non-nutrient material increases the growth of the micro-organism and the yield of glucose-isomerase.

Title: Thickness and profile control of rolled - strip
IPC: B21B37/38
Filed: 1970-06-11
Abstract: Simultaneous control of thickness and profile of rolled metal strip leaving a rolling mill is ensured by measuring the force excerted on the clamping screws and bending force exerted on the rollers. The position of the clamping screws is observed and the date is fed into a computer. the measured value of the force exerted on the clamping screws is compared with a reference value, stored in the memory of the calculator and determined as a function of the required initial thickness and of the initial profile of the strip. If these are not equal, the computer determines the amounts with which the position of the screws and the bending force exerted on the rollers must vary from the initially determined values to obtain a certain initial thickness and profile. Based on results during the calculation, the variations of the clamping screws positions and of the bending force exerted on the rollers, the computer gives corresponding instructions so that the values of the initial thickness and of the initial profile of the strip equal the previously determined instruction vaues.

Title: Transfer lock for fluid matter contg. solid particles - esp. for transfer of polymer suspension from high to low pressure zones
IPC: B01J8/00
Filed: 1976-01-13
Abstract: Device for transferring a flow consisting of or contg. solid particles from one chamber to another, and esp. a polymer suspension from a reactor under high pressure to a storage vessel at or below atmospheric pressure, comprises a housing with at least one plunger. The plunger moves in a chamber which on the upstroke is connected to the compartment containing the material to be transferred. On the return stroke, the plunger chamber is connected to the passage along which the material is to be evacuated, and during each stroke, there is a period when the plunger chamber is isolated from both the other zones. The absence of side loading on the valve details reduces friction and hence wear. When two or more plungers are used, they are in balance and only the friction between the housing and the plunger has to be overcome. In the case of polymer suspensions in low boiling pt. dispersive agents such as fluid propylene, xylene, etc., the expansion caused by boiling when the suspension moves from the high to the low pressure zone can be used to seal the joint between plunger and housing.

Title: Controllable changeover device includes a housing and a rotor - with fixed ratchet operated by an element contg. a press. compensating medium which reduces the power required
IPC: B65G51/24
Filed: 1976-07-30
Abstract: A controllable change over device for the transport of a tool through pipelines, and more esp. pipelines laid under water of the type comprises: (a) a housing (I); and (b) a rotor (II). (I) has a first port which can be connected with a first pipeline for the passage of the tool, and with a series of second ports which can be brought into connexion with a series of second pipelines for selecting the direction of transport of the tool. (II) is rotatable in the housing and having therein an elongated intermediate channel for the transition of the tool, one end of this channel remaining in direct connexion with the first port, while the other end can be selectively brought into direct connexion with a second port, depending on the controlled rotation of the rotor in the housing. The improvement comprises mounting fixed ratchets on the housing and recesses on the rotor for fixing this in a pre-determined position with respect to the housing. Each ratchet is operatable by means of an operating element provides with a plunger therein. The pressure medium within the rotor housing has access via a channel in the plunger to a pressure-compensating chamber within the operating element for the ratchet, in order to provide pressure compensation in the plunger for that element. Advantageously, the pressure compensating chamber is party delimited by the plunger and by a plug telescopically incoporated in the chamber. The use of a compensating pressure medium reduces the power to operate this pipe cleaning system.

Title: Extractor for lungs and other organs of slaughtered fowl - preventing loss of vacuum when hooks are empty
IPC: A22C21/06
Filed: 1979-10-12
Abstract: Suction pipes with a mouthpiece reciprocate vertically and travel synchronously with a transporter carrying the hanging carcases of fowl from which the lungs and other organs are to be extracted by vacuum. Each pipe is fixed to a carriage which can be displaced along vertical guides forming part of a frame moving with the transporter. Carriage works with a fixed curved track via a cam follower. During part of the vertical motion which is regulated by the cam track, the suction pipe is connected to a vacuum line. The frame section has means of spreading the legs of the fowl and brackets into which the trunk of the fowl is received. On the frame section, at the suction pipe and at the height of its mouthpiece, a resilient organ is contacted by the carcases, and in the absence of a fowl from the corresponding hook, it projects into the path of the pipe mouthpiece. Prevents the loss of vacuum and inefficient sucking away of the entrails due to the failure of the personnel to hang the birds on to the hooks with 100% efficiency.
