Title: Counting or registering apparatus
IPC: G06M1/14
Filed: 1938-09-05
Abstract: 504,099. Transfer mechanism. HILSON, O. V. Sept. 5, 1938, No. 25911. [Class 106 (i)] Transfer mechanism for the numeral discs of a registering mechanism such as described in Specification 440,857 comprises a transfer effecting member actuated by the lower disc and a locator member movable relatively to-the pivoted member and co-operating with the next higher disc. In the form shown in Fig. 2 a tooth 15 on the units disc 3 co-operates with a projection 14 on a pivoted member 13 so that when the member is rocked the V-shaped extremity thereof enters the space between two of a series of equally spaced pins 16 on the next higher disc 4. A projection 18 on the member 13 engages a spring controlled locator member 17 mounted on the same pivot and formed with a V-nange 20 having arms of unequal length to prevent rotation in one or other direction. During the transfer operation the member 17 is moved with the member 13 to withdraw the flange 20 from the path of movement of the pins 16 and on the return to normal the flange engages a pin 16 to locate it in correct position. A pin 23 on the tens disc 4 co-operates with a slightly different form of transfer mechanism comprising the member 13a, and locator member 17a to drive the hundreds disc 5.

Title: Seismology
IPC: G01V1/42
Filed: 1972-06-05
Abstract: 1382708 Seismic investigation of strata VEDECKOVYZKUMNY UHELNY USTAV OSTRAVA-RADVANICE 5 June 1972 [29 June 1971] 26115/72 Heading H4D Changes in thickness of and the extent of dislocations in a mineable layer, e.g. a coal seam, are investigated by placing charges along a line in the central zone of the layer thickness, firing the charges simultaneously to generate directional Rayleigh waves which are mode-converted into transverse waves having oscillation components within the plane of the layer and parallel to the wavefront of the Rayleigh waves, and detecting the transverse waves, after propagation in the layer, with seismic detectors located in the central zone at a free surface where the zone is intersected by a mine gallery. As shown, mirror-symmetric Rayleigh waves 9, 10, generated by firing charges at 5, propagate in direction x in the upper and lower boundaries of coal seam 1 and produce varying compression of seam 1 which results in a transverse wave propagating in direction x with oscillation components in direction y. The transverse wave passes through or is reflected by a region being investigated and is detected by geophones at the free surface location. The geophones are arranged in two groups, each geophone of one group having its axis of maximum sensitivity in a first direction lying in the plane of the seam, and each geophone of the other group having its axis in a second direction normal to the first and lying in the plane of the seam. This gives good sensitivity for waves received over a broad angular range. The geophone outputs are recorded and timed. Various linear arrangements of the charges are disclosed (Figs. 3a to 3d, not shown).

Title: Improvements in or relating to the production of non-splintering laminated glass
IPC: B32B17/10
Filed: 1935-09-20
Abstract: Sheets for use as interlayers in compound glass are made by polymerizing vinyl acetate or an acrylic acid substantially completely with the aid of, e.g. an uranium salt or organic peroxide, disintegrating the polymer, mixing it at 60--70 DEG  C. with a softening agent, e.g. a phthalic acid ester, heating rapidly to 120--140 DEG  C., and extruding on to a hard, smooth, e.g. metal surface, as by the use of compressed air, to form a layer which does not adhere to the surface.  The sheet is immersed in an adhesive consisting of high-boiling ester such as a phthalate and incompletely polymerized vinyl acetate or acrylic acid ester, and united with the glass sheets by heat and pressure.  According to the Specification as open to inspection under Sect. 91, the sheets are formed by spraying, and may be inserted between a transparent sheet and a metal reflector, in reflecting signs. This subject-matter does not appear in the Specification as accepted.
Patent GB-629444-A (GB)
Title: Improvements in or relating to electric frequency discriminators
IPC: H04L27/14
Filed: 1947-09-29
Abstract: 629,444. Phase and frequency measurements. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Sept. 29, 1947, No. 26263. [Class 37] [Also in Group XL (c)] A frequency- or phase-modulated wave is combined with a reference wave in a plurality of rectifiers in a plurality of phase relationships and the resulting differently-phased output waves are combined in pairs and fed to a second set of rectifiers, the combined output of which represents the frequency deviation of the F.M. wave. The discriminator may be used in frequency or phase modulation receivers, frequency-shift telegraphy receivers, frequency monitoring, automatic control systems, and radio direction-finding systems of the kind described in Specification 594,530, [Group XL]. In a modified arrangement, the reference wave is replaced by a delayed version of the modulated received wave. The modulated wave is fed at terminals 1, 2 to a phase-splitting circuit which as shown provides four phases 90 degrees apart at the terminals ABCD. The reference wave is fed at terminals 3, 4 to the tuned circuit F which is connected on one side to centre taps on the coils of the phase-splitting circuit. In this way the reference wave is combined with each of the phases in rectifiers a b c d respectively. If # represents the instantaneous phase deviation of the received wave, the rectified voltages at the points X Y X<SP>1</SP> Y<SP>1</SP> are represented by sin #, cos #,- sin #-, cos #. Each of these voltages is combined with the differential of its upper neighbour in rectifiers p q r s respectively, and with the differential of its lower neighbour in rectifiers p<SP>1</SP> q<SP>1</SP> r<SP>1</SP> s<SP>1</SP>. The rectified outputs of the first rectifier set are combined at the terminal 5, and of the second set at terminal 6. Assuming square law rectification, the Specification shows that the resultant across the terminals 5, 6 is d#/dt which represents the frequency deviation of the input wave, and when integrated represents the phase deviation. Differentiation of the voltage at terminals X ... Y<SP>1</SP> is effected by condenserresistance circuits between these terminals and the rectifiers. In a modified arrangement shown at the left of the Figure, the reference source is omitted, and the input modulated wave is applied directly to the terminals 1, 2 and indirectly through a delay network N to the terminals 3 4. The time delay should be small compared with the period of the highest signal frequency. The output at the terminals 5, 6 is represented by d<SP>2</SP># /dt<SP>2</SP>, and frequency deviation is registered if the output is passed through a single integrating circuit, whilst phase deviation is registered by adding a second stage of integration. When, as in the system described in Specification 594,530, [Group XL], the phase of the input wave changes suddenly at recurrent intervals, the time delay should be equal to the interval.

Title: Improvements in or relating to electrical impulse translating circuits
IPC: H04Q1/446
Filed: 1946-09-02
Abstract: 623,572. Alternating - current signalling. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., and KING, P. M. Sept. 2, 1946, No. 26331. [Class 40 (iv)] [Also in Group XL (b)] In a signalling circuit, pulses of alternating current which may vary in level and duration are converted into direct current pulses whose duration is independent of such variations in the alternating current signals. As shown in Fig. 1, the A.C. pulses are stepped up by transformer T1 and rectified to cause striking of the tube CT. Operation to transient signals is prevented by the delay circuit C1, R1. When CT strikes, high-speed relay A operates and energizes B which operates slowly due to the connection of condenser C2 in series with its winding 2, and to the connection of the windings in parallel opposition at this time. As soon as B operates, A is released and opens the holding circuit of B, whereupon the condenser C2 discharges through both windings of B in series and the windings now being series aiding, the release of the relay is thereby delayed. In this way the output contacts b3 of relay B are operated for a constant period dependent only on the value of C2 and irrespective of the level or duration of the incoming A.C. impulses.

Title: Improvements in or relating to armature testing methods and apparatus
IPC: G01R31/06
Filed: 1953-09-25
Abstract: 725,916. Testing armatures. FORD MOTOR CO., Ltd. Sept. 25, 1953 [Sept. 25, 1952], No. 26430/53. Class 37. Relates to apparatus for testing D.C. armatures of the kind carrying a commutator having a number of bars which is an even multiple of four. The apparatus includes microswitches LS1-10 and LS13 and a testing fixture having contacts 1-10 which are specially arranged and register with bars of the commutator whereby a Wheatstone bridge of the armature windings may be realized through contacts 2, 6 (input) with 4, 8 (output) or 1, 5 (input) with 3, 7 (output). Electrical balance.-The operator changes over ganged switches LS2-1 and LS7-10 so as to apply A.C. across 2, 6 from oscillator-amplifier V1/V2-V3 via transformer Tl and in the event of unbalance collect an output across 4, 8 and convey through transformer T2 into amplifier V4 and fire a thyratron V5 which operates a neon lamp N1 through LS6. The test is also made by energizing across contacts 1, 5 and taking off 3, 7 and if there is unbalance the thyratron fires with LS7-10 in the positions shown. Grounds.-If the windings are grounded through the armature shaft contact 5 is effective in circuit to resistors R26, R25 and R23 to light neon lamp N2. The micro-switches are not involved in this test. Correct angular relationship between the points at which the armature coil leads emerge from the core and the bar at which the coil is connected.-A magnetic pick-up L2 is loccted adjacent the armature so that it generates an A.C. dependent on the current through the windings during the balance test. The L2 output is delivered via a transformer T4 into a thyratron V7 which fires if the L2 output corresponds to the correct angular relation. The firing of V7 operates relay CR1 to light indicator lamp 13. This test is made by closing LS1 and is performed with the balance test which utilizes test contacts 2, 4,6,8. Short-circuit clearance.-This is done by discharging a heavily charged capacitor C14 across the armature through diametrically opposite commutator bars. As the armature is thrust into the testing fixture LS13 is closed shortly after 3 and 7 touch the commutator bars so that relay CR3 operates to close its upper contacts and C14 thereupon discharges through the armature coils. The heavy discharge current will move temporary short circuits by melting or vaporizing the offending metal. Correct mounting of armature and correct contacts.-Micro-switches LS2 and LS3 pass A.C. from transformer T5 to test contacts 1 and 9, 10 and indicator lamps I1, I2 light up if the proper contacts have been made.

Abstract: 1301067 Fertiliser spreaders AMAZONENWERKE H DREYER 19 April 1971 [14 April 1970] 27017/71 Heading AID A spreader 3 for use in a machine 1, 2, 3 for discharging pulverulent and granular material, comprises a conveyor, preferably screwtype 18, 21, 21' contained in casings 24, 25, 25' having outlet apertures 26 for the material, slide plates 27 having corresponding alignable openings 28 and being slidable relative to the casings for opening and closing apertures 26, and holding means e.g. holders 29 and springs 31 Fig. 2, or hinged members 41 Fig. 4, for holding the slide plates against the casings. The holding means are movable away from the casings, in Fig. 2 by moving holders 29 onto thick guide pieces 33, and in Fig. 4 by pivoting member 41 about hinge 42 after releasing elastic element 38 out of forked member 40, so that the slide plates are held clear of the casings in order to facilitate access to the outlet apertures 26. Hinged covers 37, Fig. 4 may be provided for the casings and are held down by elements 38. Preferably the conveyor is in section 18, 21, 21', these interconnected by flexible couplings 22 and the end sections 21, 21' are journalled in bearings 23 flexibly mounted on the casing and walls. On either side of a drive unit 15 are walls 16 and spaced outwardly from these are further dividing walls 58, the combination of which prevents ingress of material to the gears of units 15 since material passing through or around walls 58 falls through apertures 61 on the casing. In use material passes from hopper 1 through chutes 11 and apertures 59 into the casing. The spreader 3 may be detachable from the machine by releasing pins 7 and 57 and bolts 5 are then withdrawn. No tools are required. The side sections 14, 14' of the spreader may be folded up about central section 12 by means of pivots 13, bearings 22 being split (Fig. 5 not shown).
