Title: Shelving system with hollow columns and U=section supports - has extra support member on supports ensuring firm seat free from play
Inventor: BOHNACKER RUDOLF
IPC: A47B57/42
Filed: 1978-10-03
Abstract: The shelving comprises U-section supports which hang from the rows of window slots in the rails or hollow columns wherein each individual support (5) has at least one support member (10) above the bearing points which form the ends of inner hook shapes. The support member likewise adjoins the front face of the rail and locks the support in the first instance against swivelling up and out. The fixed seat of the support means that locking tongues are no longer necessary so it is easier to hang up the support shelves. Should the support shelf be accidentally knocked from below the leverage effect on the support is so great that it encounters considerable friction resistance at the front face to prevent the support from being lifted out.

Title: Telecommunications electronic controlling switch - has input transistor sensing positive, negative or earth to provide off or earth output condition on paralleled transistors
Inventor: MUELLER JOHANN
IPC: H04Q3/52
Filed: 1979-01-31
Abstract: The electronic switch is for telephone exchange use. The switch is off if either of two opposite potentials are applied but on if neither or the middle potential is applied. In the on condition the middle potential appears at the switch output. The middle potential being grounded. The switch has two output transistors (T1, T2) and more could be provided in parallel. All the output transistors are commoned to the collector the input transistor (T) by their bases. A two section centre tapped supply battery is used to power the circuit which has positive (P), centre earth (C) and negative (D). With an open circuit input (E) earth is on the base of the first transistor (T) from the base resistor (R) and negative on the bases of the output transistors because the input transistor is not conducting. Output transistors are off and earth is on the output (A1, A2) from the rectifying diodes (G11, G12) in the collector circuits. When potential is applied to the input (E), the first transistor conducts and causes current flow around the output transistors because they still do not conduct but are by-passed by diode and resistive circuits which cause potential to stand on the outputs.
