Title: Moisture measuring apparatus
IPC: G01N27/22
Filed: 1976-06-28
Abstract: 1520894 Measuring dielectric loss of materials J BILBROUGH 28 June 1976 [5 July 1975] 28444/75 Heading GIN The dielectric loss of a sample e.g. moisture content is determined by placing the sample in an electromagnetic resonant cavity which is in two parts. In the arrangement of Fig. 1 micro-wave energy from a generator, not shown, is passed through waveguide 10 into a cylindrical TM 012  resonant cavity in two parts 3, 4 connected by a frame 6 so as to define a gap 2, a choke 5 being machined in part 3 to electromagnetically couple the parts 3, 4 and prevent loss of energy through the gap 2. Initially with no sample present the length of the cavity is adjusted to resonance by means of piston 1 until a maximum signal is obtained at a detector associated with output waveguide 11. Sample material to be tested e.g. a sheet 8 which is positioned in gap 2 or granular material 9, is positioned in the cavity and the piston 1 screwed into the cavity until a new resonant maximum is obtained, the difference being a measurement of the dielectric loss. Alternatively the first maximum may be restored by removing attenuation from one of the waveguides provided by a mechanical or semi-conductor attenuating element, the amount of attenuation removed being a direct measurement of the dielectric ions. The sample may be supported on a tray located in slot 2, Fig. 2 (not shown). Instead of tuning the cavity the frequency of the generator may be varied.

Title: Pneumatic thermostat
IPC: F24F11/76
Filed: 1975-07-09
Abstract: 1487672 Pneumatic thermostat POWERS REGULATOR CO 9 July 1975 [9 April 1975] 28907/75 Heading G 1D [Also in Division G3] A pneumatic thermostat comprises means for receiving a variable pressure air supply, means for generating from said supply a substantially constant pressure air-flow which is received in a first chamber, and temperature responsive means disposed within a thermometric chamber which adjusts the pressure in the first chamber in response to changes in ambient temperature. An outlet communicating with the first chamber is provided for transmitting a pressure signal indicative of the ambient temperature, and an aspirator is further provided for drawing ambient air through both the interior of the thermometric chamber and a space immediately adjacent the exterior of the thermometric chamber. As described, the thermometric chamber 250 is part of a heat sensing and aspirating component 200 that is mounted at one end of a terminal diffuser 202 positioned in the ceiling 204 and engaged with a discharge duct 206 of an air distribution system. The provision of an aperture 252, Figure 9 allows aspirator 260 to draw ambient air through space 212 to eliminate spurious heating of the temperature sensitive element due to the proximity of duct 206. The temperature sensitive element is a bi-  metallic lever 153 which regulates the air discharge from nozzle 142. Air at pressure P 1  flows into a lower section 131 of pressure reducing chamber 130, and bleeds, via a ball and seat arrangement, into an upper section 132 communicating with the air distribution system which is at pressure P 2 . A substantially constant reduced pressure P r  is thus maintained within section 131 which section communicates with pressure transmitting chamber 140 via aperture 139. Conduit B connects chamber 140 with chamber 150 via the nozzle 142 so that the air discharge from the nozzle which varies with ambient temperature is experienced as a pressure signal P c  in chamber 140 and transmitted to a flow regulater by conduit 116. Reference has been directed by the Comptroller to Specification 1434803.

The table preferably comprises stretched spaced wires 13 arranged either in one plane or in arcuate cross-sectional relationship so that the inner wires are slightly below the outer wires to prevent lateral displacement of the biscuits. When a number of hoppers 11 deposit a row of biscuits on the table 13, a corresponding number of arcuately arranged groups of wires are provided. The hopper 11 is open at its front side and is arranged so that the biscuits lie in a position to be accommodated in V- shaped groups of pins 18 on the conveyer 16. The pins 18 project between the wires 13 and remove the bottom biscuit 10 from the hopper. The cream is applied by a rotary drum 14. A cover biscuit may be supplied from a hopper 15 to form sandwich biscuits, the relative slopes of the conveyer 16 and table 13 being arranged so that the fingers 18 project sufficiently to remove the bottom biscuit from the hopper 15. Alternatively, the table 13 and conveyer 16 are arranged parallel until the creaming position is passed, the conveyer 16 then being inclined upwardly relatively to the table to project the fingers 18 further. The creamed biscuit or sandwich biscuits are removed to the discharge shoot 21 by a rotary armed member 20. Specification 447,241, [Group II], is referred to.

Title: Apparatus for reproducing magnetically recorded television signals
IPC: H04N5/782
Filed: 1964-07-15
Abstract: 1,010,405. Editing magnetic tapes. FERNSEH G.m.b.H. July 16, 1964 [July 20, 1963], No. 29065/64. Heading G5R. Apparatus for reproducing video signals from a magnetic tape upon which they have been recorded in a series of tracks extending transversely across the tape comprises a rotatable carrier 21 provided with a number of heads 1 . . . 20 arranged, as said member rotates, to engage the tape at different positions relative to a fixed plane perpendicular to the axis of rotation of the carrier 21. The apparatus is used for editing, and the heads are arranged in a single turn helix around the circumference of the carrier 26, the axial distance between heads being such that with the tape stationary the successive heads scan successive transverse tracks to reproduce a repeated sequence of video signals corresponding to at least one picture frame. Instead of a single turn helix the heads may be arranged in a multi-turn helix, Figs. 9-13 (not shown). The heads, Fig. 5, are arranged in slots cut around the circumference of the carrier the axial spacing of the gaps 26 being by means of nineteen washers 39 having the same width as the gap, which are placed on either side of the head. Instead of a helical head arrangement, four coplanar heads 1 ... 4, Fig. 14, may be employed, and the carrier reciprocated axially by means of a rotating cam surface 64. This cam is driven via a clutch 71 so that with the clutch disengaged normal playback may be employed from a moving tape for monitoring. When the required frame is arrived at, the tape is stopped and the clutch engaged to give repeated scanning of the same frame. In operation, the tape is fed past a head carrier 103, Fig. 17, of one of the types previously referred to, and round a drum carrying two heads 81, 84 which are rotatable to scan the associated longitudinal sound and control tracks. A further drum 91 is also provided to store the signals on the loop being scanned when cutting. The length passage to be edited is selected by means of a contact 116 which engages with a rotating cardioid shaped element 115. By moving the contact further outwards, the engagement time between the contact 116 and element 115 is reduced. Cutting may then be effected by means of a knife blade, Fig. 18 (not shown). In a modification the temporary storage drum 91 is included within the main drum, Fig. 19 (not shown).

Abstract: 488,076. Resonant circuits. LORENZ AKT.-GES., C. Oct. 26, 1937, No. 29225. Convention date, Oct. 27, 1936. Drawings to Specification. [Class 40 (iii)] In tuned circuits in which the change in capacity due to change of temperature is compensated by a corresponding change in inductance, means are provided for ensuring that the temperatures of the two elements shall change at corresponding rates, in order that the frequency may not be disturbed during the process of change. Thus, if the condenser tends to change its temperature more rapidly than the inductance, it may be surrounded with heat-insulating material ; or both elements may be enclosed in separate heat-insulating receptacles. The walls of the receptacles may be of ceramic material or, if they are within the electric field of the circuit, of material having low dielectric losses. The Specification as open to inspection under Sect. 91 describes also the inclusion of both elements is a common heat-insulating receptacle, which ensures that both shall change their temperature slowly and at the same rate.

Title: Ultra-sonic pulse echo investigation
IPC: A61B8/00
Filed: 1973-06-20
Abstract: 1425082 Ultrasonic testing SIEMENS AG 20 June 1973 [23 June 1972] 29404/73 Heading H4D  In ultrasonic examination equipment, the time interval between ultrasonic pulses applied to the test object is made less than the sum of the time required for the injected and echo pulses to traverse a coupling or preliminary path, and the time for formation of echo images. A transducer 12 emits pulses into the object, e.g. a human body, and echoes are received at transducer 13. The injected and echo pulses have to traverse a coupling 5, e.g. water in a container. The transducer 12 is activated by an ultrasonic generator 14, the pulse repetition frequency being wobbled by generator 15. The time t s  between emitted pulses (Fig. 3) is less than the time required for the echo pulses to  return i.e. is less than the time for the injected and echo pulses to traverse coupling 5 and to travel in the test object. Thus, the echo pulses E 1  of, e.g. injected pulse S 1  occur after injected pulse S 2 . In this way the pulse repetition frequency is higher and the processing or image forming time is smaller than if t s  was sufficient for the echoes of a particular pulse to return. Bi-stable 21 is switched over at each pulse transmission and operates monostables 22, 23 in turn. The monostables 22, 23 each provide a delay corresponding to the travel time t v  in coupling 5 and operate a further monostable 24 which produces a voltage U7 (see Fig. 3) for delayed triggering of a sawtooth generator 25 producing a deflection voltage U8 for cathode-ray tube 18. A receiver amplifier 16 provides signals to the tube for indicating the echoes, either by deflecting or bright-up of the electron beam. If the transmitter 12, and receiver 13 scan the object, then the scan drive means operates a sawtooth generator 28 for producing a line scan on screen 19.
