Title: Explosion proof type industrial robot - contg. several drive motors with through bores for pressurised cooling gas and has at least one space filled with impervious foam
Inventor: OHTANI YUKIO
IPC: B25J17/02
Filed: 1990-10-19
Abstract: An industrial robot has a number of chambers, each of which holds a drive motor. Safety gas is fed into each and out again and is produced at a pressure higher than ambient; a sensor records the temp. in the case of at least one of the motor chambers. The construction pref. includes one space filled with foamed "phenol" (N.B. this presumably means phenolic resin, not phenol). Robot has a motor (207) to drive a turntable (203), a motor (210) to drive an arm (204) and another motor (211) for another arm (205). Motor (207) has a centre bore for gas and peripheral bores for the same purpose. The other motors also have flow bores for gas. Temp. sensors are located in the flow passages. The safety gas flowing is e.g. compressed air or an inert gas at a set pressure and it cools the motors concerned. A regulating system adjusts gas pressure according to the temps. recorded. In an example each motor has a stator (409) inside its rotor (411), and the open space (416) inside contains a cable bore (401) (also gas-cooled) and the filling (400) which is not porous to the as. This filling is light-Weight fOam and soft enOugh tO preVent any damage to the cable. ADVANTAGE - The internally pressurised design ensures that it is safe from risk of exploding. Moreover it considerably reduces the resistance to flow of purging gas.

Title: Fibre reinforced resin mouldings prodn., esp. leaf springs - by press moulding several laminate strips so that the resin curing reaction proceeds smoothly from one surface to the opposite surface
Inventor: LEONHARD CHRISTIAN
IPC: B29C70/46
Filed: 1991-03-02
Abstract: Prodn. of moulded prods. (I), esp. laminated springs, from fibre reinforced, liq., heat curable synthetic resin (II), by impregnating the fibre (in the form of strand, bundles, or woven or non-woven mat) with (II), converting into a laminate sheet, opt. cutting into strips, and curing a combination of several strips by heating in a press. The novelty is that the layers of laminate strips are hardened by applying the pressure to the largest opposite surfaces of the moulding so that the curing process starts from one of these surfaces and proceeds towards the other. More specifically, one surface of the moulding is heated to 5-50 deg.C above the starting temp. (T) of the resin curing reaction and the opposite surface surface is heated to 50-30 deg.C below T. The resin in the strips differs in reactivity, basically showing a continuous change in reactivity over the cross section of the moulding. USE/ADVANTAGE - The process enables the prodn. of laminated springs, etc. with a large cross-section, without shrinkage, delamination or cracking (contrast prior-art processes in which both surfaces harden before the middle of the moulding)

Title: Silo with vibrating discharge chute - has vibrators attached to chute to generate vibrations to prevent clogging
Inventor: GUDEHUS GERD PROF DR ING
IPC: B65D88/28
Filed: 1991-06-19
Abstract: The discharge of the contents of a silo is maintained at a cosntant rate by means of an attached device. The device consists of a conical outlet chute (3), which reduces in dia downwards.
