Title: Monoallyl maleate prepn - by triaryl phosphine-catalysed reaction of maleic anhydride and allyl alcohol at room temp
Inventor: HACKER HEINZ DR RER NAT
IPC: C07C67/08
Filed: 1974-09-30
Abstract: Parent Patent discloses a process for prepn. of monoallyl maleate (I), having a low diallyl maleate (II) content, by reacting equimolar quantities of maleic anhydride and allyl alcohol at 30 degrees C in the presence of 0.05-1 wt.%, w.r.t. total reactants, of >=1 weak tert. base. In present Patent of Addn., the weak tert. base consists of >=1 triaryl phosphine, pref. PPH3. (I) are used in prepn. of self-crosslinking epoxide-(I) adduct-based resins and as components in poly-addn. and/or polymerisation crosslinking casting resins. Highly pure (I) can be prepd. in prepn. of transparent polyepoxide/acid anhydrice/(I) casting resins, esp. for optical-electronic components. Use of 0.5-1 wt. % catalyst reduces reaction times to 2/3 to 1/2 of those required in tert. amine-catalysed synthesis, giving (I) having a still lower (II)-content.

Title: Doll uses spoon, swallows and fills its nappy - spoon pressed to mouth starts electric motor
Inventor: CUMMINGS CHARLES A
IPC: A63H3/24
Filed: 1974-11-08
Abstract: The doll has a mechanism for taking in semi-solid food, with lip movements and swallowing movements, and propelling it along an internal tube to a nappy. A spoon, pressed to the doll's mouth, closes a contact and starts an electric motor which, through a gear train, moves a lever up and down in the doll's head, so that the upper lip comes down to sip and take in the food, then the mouth opens again and the internal tube is squeezed to move the food on by peristalsis. The motor, started by the spoon, does not stop at once when the spoon is removed, but continues to run until a particular gear wheel has completed a whole number of revolutions.

Title: Non rubbing door leaf bottom sealing - comprises foil strip on batten displaced by protruding lever
Inventor: GRELL OSKAR
IPC: E06B7/20
Filed: 1975-07-10
Abstract: A strip of foil stretches along the bottom of the door leaf. The other edge is fixed to a batten held at the bottom of the leaf. This batten can be displaced, against spring action to the thickness of the door leaf. This is done by a lever protruding at the side of the lintel to abut onto the door-case and swivel, when the door is being closed. The batten may be held by two sheet metal strips fixed on the bottom of the door. The displacement of the batten causes the foil strip to bulge against the floor, in the final stages of movement.
