Title: Hospital beds
IPC: A47C21/08
Filed: 1973-11-01
Abstract: 1441786 Hospital beds SIDDAL & HILTON Ltd 30 Oct 1974 [1 Nov 1973] 50784/73 Heading A4J [ Also in Division E2 ] A side frame of a hospital bed is pivotably foldable to a stowed position after being freed by an initial translatory motion relative to the bed frame. As shown Fig. 1, (not shown) the side frame is of the parallelogram linkage type and remains in a vertical plane along one side of the bed in both collapsed and erect positions. A fitting 10 Fig. 2 controls side frame support arm 22 furthest from the patient. Lands 16, 18 project from the fitting 10. Co-operating notch 28 and lug 26 are formed on fitting 10 and support 22 respectively. A safety catch 32 is operated by handle 38. Operation:- After clockwise rotation of handle 38 (either against gravity or spring-bias or both) the member 22 is raised vertically to allow the lower heel to clear corner 42 of land 16 and to allow lug 26 to clear the top of the fitting 10. Clockwise rotation of support 22 about pin 20 is then possible. To re-errect, the support 22 is rotated anti-clockwise, the cam surface 40 coacting with the corner 42 to cause lug 28 to clear the top of the fitting 10. When vertical, the support 22 drops to the position shown and is automatically locked by catch 32.

Title: Comparators

Filed: 1969-10-20
Abstract: 1283959 Comparator circuits INTERNATIONAL BUSINESS MACHINES CORP 20 Oct 1969 [19 Nov 1968] 51350/69 Heading H3T In a comparator a fixed level is compared with the output of a signal amplifier and a reference level is applied to a similar amplifier having negative feedback which controls the operating conditions of both amplifiers such that when the signal and reference levels are equal the outputs of amplifiers are equal to the fixed level. As shown, a fixed level from a diode T4 is applied to one input transistor T 1  of a current-switching comparator circuit and the outputs of a signal amplifier T9, T10 are applied through level setting diodes D1, D2 and emitter followers T3, T12 to parallel transistors T2, T3 forming the other side of the comparator circuit. The reference signal is applied to an amplifier T14, T16 similar to the signal amplifier. The collector potential of T16 is compared with the fixed voltage (T4) and any tendency to depart therefrom is connected by a negative feedback circuit T18, T19 which controls the collector supplies of both amplifiers. As the amplifiers are substantially identical, being made as an integrated circuit, the output potentials of the signal amplifier will also be equal to the fixed potential when the signal voltage is equal to the reference. Any departure from equality in either direction will make the inputs to the comparator circuit differ from the fixed potential and an output will be produced via 20 and 21.

Heading D1E. Each pile yarn carrier 10 has a pawl 9 co-operating with notches, when aligned, in a group of selector bars 1, 2 which are individually moved by a jacquard mechanism to either a raised or lowered position so that, e.g. a group of two bars with three notches each will give four positions in which only one notch in each bar is aligned, a group of three bars will give eight positions and so on. This allows a yarn carrier to be given, say, sixteen different positions when a jacquard needs only four columns of holes, one for each bar. In Figure 8 the carriers 10 are raised during selection by a cam operated lever 41 and are lowered to allow their pawls 9 to engage the aligned notches. For selection the bars 1, 2 are raised by a cam operated lever 29 and stops 22 selected by the jacquard are pivoted under the bars so that when the bars are lowered the selected bars remain at a higher level than the non-selected bars. To save space groups of bars may be located alternatively on either side of the carriers 10 (Fig. 10, not shown) and the carriers may be raised by a resilient beam (Fig. 11, not shown). The jaquard cords are attached to the stops 22 by springs (see also Fig. 12, not shown).
