IPC: B65G67/00
Filed: 1954-03-22
Abstract: 763,271. Wagon tippers. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES. March 22, 1954 [April 11, 1953], No. 8275/54. Class 78 (4). The rollers 4, Fig. 1, engaging the end rings 2 of a tippler cage are carried by a moving arcuate member 28 and roll also on tracks 3<1> on the fixed frame 7 of the tippler. The upper part of the cage is open at b so that locomotives may pass through it. In the construction illustrated wider portions D of the rollers 4 engage the tracks 3 on the tippler rings while lateral portions d of reduced diameter engage the track 3<1> thus reducing the length of track 3<1> which must be provided. The tippler may be driven by a chain 18, Fig. 5, tensioned round a guide on the cage 2 by springs 19 and driven by a sprocket 20 connected by suitable linkage to a lever 21 oscillated between the limits indicated by continuous rotation of a crank 23 by a motor 24.

Title: Improvements in or relating to radio and other receivers of the superheterodyne type
Inventor: GOUGH MICHAEL WOODHAMS
IPC: H03J7/04
Filed: 1947-03-26
Abstract: 639,133. Automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Lt March 26, 1947, No. 8277. [Classes 40 (v) and 40 (vi)] In an A.F.C. arrangement for a heterodyne receiver of the type in which the local oscillator is frequency-modulated by an amount equal to the bandwidth of the I.F. amplifier, the resulting output of the amplifier is detected and applied to a circuit comprising two valves rendered alternately operable in synchronism with the signal. The peak outputs from these valves are differentially combined to produce the potential which maintains the mean frequency of the oscillator correct. When the mean frequency M departs from the desired value 0 an asymmetrical amplitude modulation of the I.F. signal results due to the frequency response characteristic C of the receiver, the peak value B, Fig. 3b, of the modulation coinciding with the positive or negative peak of the modulating voltage depending upon the sense of the departure. The detected output of the I.F. amplifier is applied through transformer T1, Fig. 5, to the control grids of two valves V1, V2 which are rendered alternately conducting by the application of mains voltage from transformer MS2 to the screen grids. Diode valves V3, V4 limit the positive excursions of the grids. The output from valves V1 and V2 are peak rectified and applied to valves V7 and V8, the differential output from which is smoothed by resistor R9 and capacitor C4 and fed to the grid and cathode of a valve V9. This valve is connected in a circuit with a velocity-modulated local oscillator valve V10 and varies its mean operating frequency by controlling the current flowing through its biassing resistor R11. Frequency modulation of the local oscillator is effected by applying mains voltage from transformer winding MS1 to the accelerator grid GV10. A cathode-ray tube may be used to indicate correct tuning during initial frequency adjustment. Reference has been directed, by the Comptroller to Specification 661,082.

Title: Improvements in and relating to apparatus for indicating acoustically the depth of water under a ship, or the like
IPC: G01S1/72
Filed: 1925-03-30
Abstract: 257,638. Smith, F. E., Smith, B. S., and Bellars, H. F. March 30, 1925. Determining distances acoustically.-In apparatus for measuring depths at sea by the timing of an echo, means are incorporated in the receiving apparatus for reading off the true depth D when the actual length of the path, which has been traversed by the sound, and which is proportional to the time interval between the emission of the sound and receipt of the echo, is #4D<2> + S<2>, S being the horizontal distance between the transmitter and receiver. In the arrangement shown in Fig. 1, the contacts 2 of a timing device of the receiver, e.g. of the kind described in Specification 236,601, are adjusted through a differential gear 4, 7, 1 by manual operation of a knurled head 6 associated with a wheel 5 graduated along the circumference to read off the true depth directly. The relation between the angular movement imparted to the gear-wheel 1 and that given to the wheel 4 is determined by the shape of a groove 9 cut in the wheel 7 and engaged by a fixed pin 10. For large depths, where the value of S has little influence, the corresponding portion of the groove 9 is almost circular, but at the portion corresponding to small depths the groove turns in towards the centre. The actual shape of the groove is determined by calculation or by trial at known depths. The indicating pointer 11 for the depth scale may be adjustable in its holder so that it can be initially positioned to add to the depth recorded the depth of the receiver below the surface, and thus indicate directly the true depth. In a modification, Fig. 2, the centres of two wheels 1<a>, 4<a> are situated at a distance apart proportional to ¢S and gear respectively with racks 13, 14 connected by a pivot 15 which moves in a vertical groove 16. The wheel 1<a> and rack 13 are associated with the timing device of the receiver and receive a displacement proportional to #4D<2> + S<2>, the displacement of the rack 14 and wheel 4<a>, which are associated with a depth scale, therefore being proportional to D.

Abstract: 1,151,614. Data transmission systems; V.F. signalling. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 8 Feb., 1968 [22 Feb., 1967], No. 8582/67. Headings H4P and H4R. In a frequency shift binary data receiver in which the binary data may be represented by either of two pairs of frequencies, two filters are connected in parallel, one or other filter being shorted out depending on which pair of frequencies is being received. The frequency shift signals pass via a filter 1 and emitter follower 3 to the two filters 5, 6. The amplifier is matched to the filters by resistors 16, 17. Transistors 22, 23 are selectively enabled to short the input of the corresponding filter. The filters feed mixer 8 via amplifier 7. The mixer feeds a band-pass filter connected to a limiter which feeds a tuned circuit. This develops a frequency shift signal whose amplitude varies with frequency. A rectifier derives the binary data from this signal.

Patent GB-936107-A (GB)
Title: Continuous treatment of slivers
IPC: D06B3/02
Filed: 1962-03-07
Abstract: A method for continuously and uniformly processing a continuous sliver without the application of additional twist, comprises passing the sliver continuously through a casing containing a treating fluid and having sliver <PICT:0936107/IV(a)/1> <PICT:0936107/IV(a)/2> squeezing passages with their cross-sectional dimensions so controlled relative to the sliver as to squeeze the latter to such a degree that the continuity of the sliver is maintained.  One form of apparatus is shown in Fig. 1 and comprises a cylinderical casing 3 provided at its ends with narrow inlet and outlet tubes 2 and 4. Sliver 1 is introduced continuously through inlet 2 into casing 3 which is filled with treating liquid and has an inner diameter larger than that of tubes 2 and 4 but smaller than the natural cross-sectional size of the sliver.  The treating liquid may be supplied from a pipe 6 and discharged through pipe 7 or vice versa. In other embodiments a series of narrow or restricted passage means may be arranged at intervals along the length of and within a cylindrical or tubular treating enclosure or casing whose diameter is larger than that of the sliver in its natural form. Each of the narrow passage means may be formed by a short pipe, ring, hollow disc or the like.  Alternatively a single tube or pipe having a series of narrow sections at intervals and extending longitudinally of and within the casing may be employed.  Further a coil spring whose inner diameter is smaller than that of the sliver in its normal state may be arranged within a casing.  In cases where a series of sliver passage restricting means is provided, the interval between them must be shorter than the mean length of the fibres constituting the sliver.  Fig. 7 shows another embodiment wherein a sliver 1 is continuously processed under pressure at a high temperature.  A number of pressure gas compartments 23 are provided in series at the inlet side and each is provided with a narrow tube 24 through which the sliver passes.  After passing through these compartments sliver 1 is led to a pressure steam-heating treating chamber 22.  The pulling force for the sliver is obtained by a pair of rolls 27, 27 and after treatment in chamber 22 the sliver passes through tubes 29 in compartments 28 and is delivered by a pair of rolls 30, 30 into the atmosphere.
