Title: Apparatus for automatically controlling a sheet feeder in a printing machine
IPC: B65H7/04
Filed: 1977-03-03
Abstract: 1535475 Automatic control POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 3 March 1977 [15 March 1976] 08997/77 Heading G3N Feeding of successive sheets in a printing machine is controlled in dependence on the condition of sheets detected at 3 as present absent or skew. When starting, actuator 1 causes bistable 2 to give an output. No signal from the "absent" or "skew" outputs at 8 causes bistable 18 to be set via AND gate 11 enabling the printing at 6 to proceed and setting bistable 9 via OR gate 5 enabling sheet feeding also at 6. Bistable 18 is then latched on via AND gate 11 and OR gate 16 while resetting bistable 2. A signal from the "absent" (left hand) output only, at 8, causes bistable 9 to be set via AND gate 10 enabling the sheet feed 6 and, when a sheet is detected, enabling the printing control bistable 18 via AND gate 11 as before. And a signal from the "skew" (right hand) output resets the starting bistable 2. Similarly when running, production of either absent or skew signals resets the bistables 9 and 18 via AND gate 12 and OR gate 15 disabling the sheet feed at 6. A multiple sheet detector may be added at 8 Fig. 4 (not shown) and in another embodiment Fig. 7 (not shown) detected absent, skew or multiple sheet conditions may be allowed one or more machine cycles to right themselves before running is stopped.

Title: Methods and devices for protecting electronic switches
IPC: H03K17/082
Filed: 1974-03-01
Abstract: 1462080 Protecting against short circuits ROBERT BOSCH GmbH 1 March 1974 [2 March 1973] 9269/74 Heading H2K [Also in Division H3] A control circuit for protecting a load switch 11 from short circuit of the load comprises an AND gate 17, 18, and an input stage 27, 22 providing, on actuation, signals having gateenabling states of disparate duration which actuate the gate 17, 18 to energize load switch 11, the gate receiving, at the input to which the signal having the lesser duration enabling state is applied, a feedback signal from switch 11 to sustain an input when the lesser duration terminates, the feedback signal being inhibited if the load 10 is short circuited so that the load switch is then only operated for the lesser duration. When the input at 29 is 0 v., transistor 27 is off holding transistors 22, 18 on and holding transistor 17 off so that transistor 11 is also off and the load 10 is disconnected. When it is required to connect the load, a positive potential is applied to input 29 which turns on transistor 27. This turns on transistors 17 and 11 immediately, and turns off transistor 22 after a delay due to charge storage effect. If the load 10 is not short circuit, the potential at the collector of transistor 11 maintains transistor 18 on so that transistor 11 remains conducting. If the load is, or becomes, short circuit, however, the potential at the collector of transistor 11 cannot hold transistor 18 on, so that transistor 11 is turned off to disconnect the load.

Title: Process for obtaining mouldable phenol-formaldehyde and urea-formaldehyde resins
IPC: C08G14/08
Filed: 1953-04-08
Abstract: A mouldable resin is made by mixing a monohydric phenol and/or urea with formalin, adding an alkali metal salt containing an amphoteric element in the acid component (e.g. sodium silicate, zincate or aluminate) to obtain a gel, and submitting the gel to the action of infra-red rays until the desired degree of polycondensation is obtained.  The salt may form an integral part of the resulting resin. The infra-red rays may be derived from lamps, gas burners or heated metallic elements.  In examples: (1) a mixture of formalin, phenol and cresol is added to sodium silicate solution and the mixture stirred to produce a gel which is converted into a solid mass by infra-red rays; the product is mixed with saw-dust, rice-husks, talcum or quartz, zinc or aluminium stearate and dibutyl phthalate and is then moulded; (2) a mixture of formalin and urea is adjusted to pH7.5 with ammonia and allowed to stand; sodium silicate solution is then added to produce a gel which is hardened by infra-red rays; then saw-dust, zinc stearate, zinc oxidie, pentaerythritol, hexamethylene tetramine and ethyl alcohol is added and the mixture left to dry to form a moulding composition; (3) similar to Example 2, but using a mixture of urea, formalin and phenol.
