Title: Insulins prodn - using phthaloyl protecting groups
Inventor: GEIGER ROLF DIPL CHEM DR
IPC: C07K1/113
Filed: 1972-03-24
Abstract: Insulin and analogues are produced by treating N-phthaloyl-insulin or N-phthaloyl-insulin analogues with hydrazine, a 1-4 C alkyl-hydrazide or phenyl-hydrazine in the presence of phenol or a 1-4 C alkyl-substd. phenol (opt. contg. up to 30% H2O) as solvent. The phthaloyl gps. which can be removed under the specified conditions without causing degradation of the insulin molecule, is an advantageous acid-stable protecting gp. in the synthesis of insulin chains, partic. in the Merrifield solid-phase synthesis of the insulin B-chain. N alpha A1, N epsilon B29-Bis-phthaloyl-insulin (obtainable by reacting insulin with N-carbethoxy-phthalimide at pH ca. 8.4-11) is useful as an intermediate for the B-chain degradation prodts. des-b1-4-, des-B1-5- and des-B1-6-insulin, which have almost full insulin activity but are substantially more readily soluble than insulin.

Title: Parking permit light array for cars - is plugged into car roof and is lit for permitted parking period
Inventor: HEUER SEN ERNST
IPC: G07C1/30
Filed: 1973-07-26
Abstract: The lamp array has a series of different coloured lights mounted one above the other and is plugged into a fitting on the roof when the driver parks the car. IT is removed by a special key inside the car so that it has the added advantage of deterring a car thief. Switches inside the car select the coloured light corresponding to the permitted parking period. This light is automatically extinguished at the end of the period and cannot be relit until a set time has elapsed, to prevent the driver switching it on against rather than moving the car. AN internal battery runs for a set time so that replacements can be fitted by the licensing authorities on payment of the total parking fee. Excess parking fees are collected by having a shunt discharging the battery faster after the allowed period.

Title: Horizontally or vertically pivoting window - has locking cam on vertical shaft with length ensuring locking at all positions
Inventor: FRANK GERHARD
IPC: E05D15/52
Filed: 1974-04-03
Abstract: The arrangement is for windows which can be either tilted around horizontal pivots or swung around vertical pivots. When the window is operated around either of the two pivots, the other set of pivots necessarily leaves the window frame and the present arrangement provides means to eliminate possible malfunctions of the locking mechanism by failing to block one set of pivots, when the other set is used. The operating handle on the window leaf has three positions. In the basic position the leaf is locked against the frame and cannot be opened. By turning the handle by 90 deg. opening of the window around the vertical pivots is achieved, by turning the handle by 180 deg. opening of the window around the horizontal pivots follows.
