Title: Adjustable bed
IPC: A47C20/08
Filed: 1960-11-07
Abstract: 915,849. Adjustable beds. WETZLER, J. Nov. 7, 1960, No. 38201/60. Class 52 (2). An adjustable bed includes a relatively fixed frame structure 1, a movable frame structure 7, a mattress supporting structure 8 divided into a plurality of sections 9, 11, 12 and 13 operatively associated with the movable frame structure 7 for vertical movement relative to the fixed frame structure 1, at least one of the mattress supporting sections being relatively movable into an angular position with respect to the horizontal. Levers 23, 25 (Fig. 2) are pivoted to the movable frame structure 7 and support the sections 9, 12 respectively. Rollers 23<SP>1</SP>, 28 on the levers are engageable with the sections 9, 12 so that movement of the levers 23, 25 will operate the sections. A supporting member 29 is provided with projections 32 to engage in one of a number of notches 33 in the section 11. L-shaped levers 35f, 35h support the movable frame structure 7 and are pivoted to the side rails 4 of the frame structure 1 at 37, 36 respectively. By rocking the arms 35f, 35h in a clockwise direction as viewed in Fig. 2 about their respective axes 36, 37, the entire movable frame structure 7 with the sections 9, 11, 12 and 13 may be raised from a position shown in Fig. 2 to a position shown in Fig. 7. Power means such as an electric motor 46 (Fig. 2) may be provided for raising and lowering the movable structure 7. The action of the levers 35f, 35h may be varied so that one end of the mattress supporting structure will move vertically a greater distance than the other end to tilt the plane of the mattress supporting structure 8 with respect to the horizontal. This is achieved by having arms 57f, 57h of adjustable length connecting the arms 35f, 35h through a nut 56 and screw 52 to the drive from the power means 46 (Figs. 2 and 11). Stop members 84h, 84f (Fig. 3) normally hold the mattress supporting sections in a horizontal plane. If it is desired to tilt one of the sections, one of two handles 86 is rotated to adjust the arm 23 or 25 to a position which will allow the section to tilt downwardly as shown in Fig. 7. The handles 86 may be operated manually or by power-actuated means. Provision is made to permit individual movements of the sections 9, 11 and 12 during movement of the frame structure 7 and also when the frame 7 is stationary.

Title: Communication system for disseminating coded digital data in analogue form
IPC: H04B14/00
Filed: 1975-09-17
Abstract: 1519034 Bit encoding/decoding; synchronizing THOMSON CSF 17 Sept 1975 [17 Sept 1974] 38289/75 Addition to 1480367 Heading G4C [Also in Division H4] The arrangement of the parent Specification using the Walsh-Hadamard transformation, is modified in that clock signals delimiting each "N-bit group representing" analogue signal are mixed with the analogue signals rather than being recorded or transmitted separately. The present Specification also differs in that the degree to which the analogue signal has been modified by the recording or transmission process is determined and the result is used to vary the threshold used to distinguish 0 and 1 bits in the signal generated by the performance of the reverse transformation. The Specification gives the theory describing the effects of low frequency (to the extent that all components of a given group of signals are affected equally) variations in the sensitivity of the record or transmission medium on the analogue signal groups and the reconstituted binary signals derived therefrom. Because of the nature of the Walsh-Hadamard transformation it is possible to determine the degree to which the signals have been affected by sensitivity variations by forcing the first bit of each N-bit signal group to be binary 0 and by storing the level of the corresponding signal in the corresponding reconstituted N-bit signal group. Alternatively the level of the clock signal or the mean signal level of a signal group can be used to measure the sensitivity variation. The effect is shown in Fig. 4 where curves 40, 41 show the normal probability distributions for the signal levels representing binary 1 and binary 0 produced by the reverse transformation, a threshold 1/2 serving to distinguish the binary states with minimal errors. The curves 217, 218 show the probability distributions for signals affected by variations in sensitivity, the determination of the degree of the effect, k, being used to modify the threshold to 1/2.k.

Title: Improvements in or relating to apparatus for reproducing video tape recordings
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N5/783
Filed: 1965-09-10
Abstract: 1,108,088. Slow motion video playback. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Aug., 1966 [10 Sept., 1965], No. 38854/65. Heading G5R. In a system for providing slow motion playback of a video tape recording, the tape is moved at a constant fraction of the original recording speed, say 1/n, and each track representing a given picture field is scanned n times. In order to avoid the poor picture quality which would result from this simple arrangement, it is arranged that each scan of the playback heads tracks the recording properly, and that the timing of successive field scans is such that magnetic video information corresponding to any given picture element is scanned at equal intervals of time. To achieve proper tracking by the scan, the helical path along which the tape is fed past the rotating playback head is adjusted by changing the original tape helix pitch in accordance with the ratio of the recording head speed to the playback head speed, and by increasing the diameter of the head rotor and drum. To achieve proper timing, a multiple array of n spaced and offset heads is used, with appropriate switching between scans. Various arrangements of head and drum configurations are given. In order that proper interlacing and timing is provided in the final output signals for heads evenly distributed around the drum circumference, attenuators and delays may be incorporated in the lines from certain of the heads prior to the head selection output switch.
