Title: Cartridge for strip roll and strip feeding apparatus
IPC: G03B1/56
Filed: 1971-04-19
Abstract: 1343723 Cinematography EASTMAN KODAK CO 19 April 1971 [18 March 1970 ] 24552/71 Heading G2E A cartridge 10 and a film stripping mechanism 26, mounted on a plate 9 of a cine projector are designed to permit film to be stripped from the cartridge 10 even when the film 18 is loosely coiled therein. To achieve this the cartridge 10 is provided with a deflectable portion, e. g. a leaf spring 35, which is engaged by the ends of the stripping mechanism 26 so that film end 20 is forced to contact its belt 29 driven by a pully on shaft 27d. As shown the mechanism 26 includes the driven belt 29 and finger 25 which are movable under the influence of spring 53 to contact the film coil 19 on reel 17 in the cartridge 10. This movement is controlled by pin 46 in groove 47 and pin 49 on the plate 9 camming against surface 48 and notch 51. As shown the opening 35 has a bifurcated end portion 36 to permit it to tend to latch on to the bosses 33 provided at the ends of idler shaft 30. Alternatively, Fig. 4 (not shown) the spring 35 is replaced by a deflectable member (50) which is part of the cartridge wall 14 (it being deflectable by being formed as a tongue separated by slots (52), Fig. 5 (not shown), from the rest of the wall 14). This tongue (50) is engaged by a projection (54) extending from the mechanism 26. A film pressing member may be fitted to the finger 25 at the opposite end to its tip 40, to hold the film stripped from the reel flat against the belt 29 and so align it for the projector's threading mechanism.

Title: Improvements relating to annunciators
IPC: G09F25/00
Filed: 1946-08-19
Abstract: 618,273. Electric selective signalling systems; magnetic sound records. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. Aug. 19, 1946, No. 24644. [Classes 40 (i) and 40 (ii)] In a public address annunciator a number of announcements are magnetically pre-recorded in known manner on separate continuous loops of magnetic wire or tape 1 carried on pulleys 2 tensioned by weighted rollers 3, and passing through magnetic reproducing heads 4 connected to a suitable amplifier and announcing apparatus. The loops pass between rotating shaft 5 and a number of rollers 8 normally held clear of the loops by springs 9. Energization of a selected solenoid 10 causes the associated roller to press its tape against the rotating shaft which feeds it past the appropriate reproducing head so that the selected announcement is made. A short A.C. pulse recorded at the end of the latter is selected after amplification, by a tuned circuit, the output from which operates a relay to deenergize the appropriate solenoid and arrest the tape. The solenoids may be energized through switches or by impulses from other apparatus and the shaft 5 may be rotated only when an announcement is to be made. The apparatus may be associated with a visual train describer to announce train movements. In modifications, the tape may be arrested by completion of a circuit through holes in the tape, or through conducting strips applied thereto.

Title: Improvements in devices for converting electric pulse code modulation into pulse position modulation
IPC: H03M1/00
Filed: 1951-10-23
Abstract: 685,518. Pulse code modulation circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 23, 1951 [Oct. 26, 1950], No. 24706/51. Class 40 (v). [Also in Group XL (b)] Relates to decoders for receivers of signals comprising groups of n positive and negative code pulses, each group representing a modulating signal level and being taken from a series of 2n mixed pulses, the group starting with the pth pulse of the series representing the level p. As described, the decoder deals with groups of three code pulses taken from the series 00010111, expressed in the binary notation, so that, for example, the fourth of eight possible levels is represented by the group 101. The decoder is fed with positive pulses to represent the digit 1 and negative pulses to represent the digit 0, but the latter may be introduced at the signal receiver. Its output comprises single positionmodified pulses corresponding to the code groups. The decoder comprises an artificial line with ten sections and provided with ten tappings A ... H, A<SP>1</SP>, B<SP>1</SP>, the delay time between adjacent tappings being equal to the interval between the pulses in the code groups fed to the line from the radio receiver 2. The pulses of the groups are transmitted in reverse order. The tappings correspond in their connections to the pulses of the series from which the code groups are derived. Accordingly, the " plus tappings D, F, G, H, are connected through decoupling resistances 5 to a common conductor 6 and thence through condenser 7 to the control grid of a valve 8, whilst the " minus " tappings A, B, C, E, A<SP>1</SP>, B<SP>1</SP> are similarly connected to the cathode of valve 8 through decoupling resistances 3 and conductor 4. At the instant when the last pulse of a group representing level n reaches the nth tapping on the line the voltage difference between the grid and cathode of valve 8 due to the three pulses of the group is substantially three times that due to one pulse and the cut-off bias from source 9 is overcome to pass a pulse to the anode load 10. At all other instants while the pulses of a group are traversing the line, the net voltage applied to the valve is insufficient to overcome the cut-off bias, so that the time of occurrence of each output pulse is related to the signal level which the pulse group represents. The position-modulated pulses are supplied to a known demodulator 11 to recover the modulating signal. Two delay lines may be used alternately, so that all the pulses of one group reach the terminating impedance 12 before another group is applied to the input. If the time interval between successive pulses of a code group is greater than, say, one microsecond, an electromechanical delay line may be used (see Group XL (b)).
