Title: Heat exchanger with multiple coils - having inserts in front of tube plates to allow on stream maintenance
Inventor: SEIFERS HILMAR ING GRAD
IPC: F28F9/02
Filed: 1976-04-21
Abstract: Heat exchanger has a tube bundle mounted into tube plates having an outer jacket. The tube plates are mounted to the shell by distance pieces and have additional couplings on the outside. These have a cover plate facing the tube openings with holes which can be opened opposite to the tubes. The heat exchange tubes are brought out to the level of the outer shell and terminate in the tube plate. A valve can be fitted to the outer flange and the outer vover attached to this. The valve can then be opened and the removable plugs taken out to inspect the tubes and check for leaks as necessary. For use in cryogenic systems or for uranium enrichment where the exchanger must operate to a higher degree of safety and be simply and rapidly repaired if necessary. The exchanger is of relatively low cost to produce. It can be repaired and maintained very simply in a short time so that off stream time is low.

Title: Controlled release gelatin capsules - in which the gelatin shell is insolubilized with a crosslinking agent
Inventor: BLOCH RENE DR
IPC: A61K9/64
Filed: 1976-06-16
Abstract: New capsules provide for the controlled release through the capsule walls of therapeutic agents they contain. The capsule walls contain crosslinked gelatin which is insoluble in basic and acidic body fluids. The gelatin may be hard or soft the gelatin. The new capsules can be produced by existing encapsulation technology with very little modification. The sustained release characteristics of the capsules are independent of the pH of the surrounding body-fluid, so that therapeutic agent continues to be released in a controlled manner throughout the passage of the capsule through the gastro-intestinal tract. In an example, commercial hard-shell gelatin capsules are insolubilised by treating with a 1% solution of glutaraldehyde in 0.05-M phosphate buffer pH 7. After washing and drying, the capsules are filled with 37 mg amitriptyline hydrochloride, then the two capsule halves are sealed together with an epoxy resin. The rate of release of active substance from the capsule in water is 3.5 mg/hr. on average.

Title: Coin verifying unit using oscillator coil - compares rectified oscillator voltage with reference voltage as coin falls through oscillator coil
IPC: G07D5/00
Filed: 1976-08-27
Abstract: The coin verifying unit, e.g. for a coin-operating vending machine, has the coin (1) forwarded through the constant AC field of an oscillator coil (11) with the rectified oscillator voltage during passage of the coin compared with a reference voltage, to obtain a control value. The latter is used to maintain the coil voltage constant via an adjustment element (14) and is supplied to a control circuit (20) which determines whether the control value lies between upper and lower threshold values. The time constant of the adjustment circuit is dependent on the velocity of the coin (1) such that the oscillator voltage during passage of the coin remains constant, while the control value for the control circuit (20) attains the highest possible amplitude.

Title: Self fitting seat belt for car - has cable connected to door and trained around pulley to pull sprung slider along guide rail fitted at top of door frame
Inventor: BLUEGGEL ERWIN
IPC: B60R22/06
Filed: 1976-10-29
Abstract: The self fitting seat belts have the upper anchorage point (6) on a fitting sliding along a guide along the door frame. As the door is opened, a cable link (11) to te door operates on the slider to pull it away from the fitting position against a return spring force. No separate servo drive is required. The belt is automatically refitted as the door is closed. The cable drive is looped over a pulley (14) which provides some mechanical advantage, so that a small amount of door opening provides a large deflection of the slider.

Title: Capillary viscosimeter having adjustable throttle - enabling pressure to be kept constant at different rates of flow
Inventor: WINTER HORST HENNING DR ING
IPC: G01N11/08
Filed: 1977-05-03
Abstract: A viscosimeter comprises a measuring capillary duct connected to >=2 pressure recorders or one differential pressure recorder to indicate the pressure gradient along the capillary duct. On the downstream side, the entire flow of fluid or a part thereof must pass through a throttle, esp. a throttle adjustable infinitely or by steps and also capable of being completely closed. Used esp. for measuring the viscosity of non-newtonian liquids such as plastics, where it is necessary to vary the pressure of the flow as well as the pressure gradient due to the variation in viscosity with shear rate.

Title: Separating appts. delivering single pieces from goods stacked upright - has retaining element for top of object and trough for bottom
Inventor: GLAUSCH ERHARDT
IPC: B65G59/08
Filed: 1977-05-28
Abstract: Separating appts. supplies single pieces from goods stacked upright in rows, such as records or books, making sure that none is damaged and they do not clamp together so that two or more are delivered instead of one. The plate-like goods are pushed forward onto a sliding arrangement. A retaining element for the top edge of the first example of the stack is used. The sliding, forwarding arrangement has a trough positioned opposite the retaining element to hold the bottom of the example when it is slid forwards. The relative positions of the upper retainer and lower recess is such that the example is inclined. The distance of the retainer from the forwarding path is less than the height of the stacked objects yet it releases the held example into the lower trough.

Title: Centrifugal dental casting machine with arms - has drive with spring loaded balancing and holding arms for crucible
Inventor: THOLEN UWE
IPC: A61C13/20
Filed: 1977-06-02
Abstract: The centrifugal casting arrangement is used especially for dental purposes. Connected on the drive by a lever with vertical rotating axis, a centrifugal force arm carries the melting crucible and casting sleeve. The drive carries also on the other side a counterbalancing arm. Starting of the centrifugal action with incorrectly positioned arm components is reliably avoided and the casting process is optimised. Between each of the two arms (4, 7) and the driving arrangement (2) are fitted springs (9) which attempt to pull the arms into pivoted initial position. Second springs (11) are fitted between each arm and the driving arrangement. These springs are connected only on one end with the driving part or one of the two arms. They are loaded in compression and exert greater force than the first springs (9).

Title: Plastics coating applicator for coil winding machine - has protection for flange on small former to apply external force acting inwards along axis during winding
Inventor: WASNER GUENTER
IPC: H01F41/098
Filed: 1977-08-10
Abstract: A coil winding machine is used which will take small plastics formers without damaging the joint between the flange and the main body of the former. This is achieved by balancing the stresses along the longitudinal axis during the winding process by an externally applied stress in the opposite direction. The external forces are applied to the unwound former (1) which has flanges (3, 4) at both ends. The forces will be applied during the winding process along the longitudinal axis of the former and act inwards. The force is exercised by a tensioning device such as a mandrel (7). The mandrel is fitted to a threaded rod (10) and can therefore be adjusted.

Title: Heat insulated door or window frame profile - has insulating plastics insert fixing interlocking metal sections to reduce heat flow
Inventor: WILLERT OTTO
IPC: E06B3/263
Filed: 1978-01-14
Abstract: There are two metal profile bars and an intervening insulating profile, of stable plastics, in the heat-insulating composite profile units, esp. for window or door frames. Stem pieces (15) on the outside profile (2) enclose a T-shaped extension (13) with grooves (19) on the inside one (3), over sufficient length for firm joining. The insulation profile (1) fixes the metal units vertically by virtue of its shape. It reduces heat flow with a series of sealed chambers (4-9), and with small contact surfaces (10) and radiation screens (11, 12). This is simple and stable, but not liable to fall out under high temps. in the event of fire.
