Title: Improvements in or relating to sliding roofs for vehicles
IPC: B60J7/185
Filed: 1938-01-28
Abstract: 488,361. Vehicle opening-tops. BISHOP, W. H. Jan. 28, 1938, No. 2687. [Class 108 (i)] In a vehicle opening- top comprising a longitudinally - slidable panel adapted to close or uncover an opening 11 in the roof, the panel 10 slidably engages intermediately of its width a stationary longitudinallyextending member, such as a steel strip 17, and carries means co-operating with the member to lock the panel in any desired position. As shown, the strip 17 is secured at its rear end to a fixed cross-member 18, Fig. 2, and extends under a fixed canopy 12, beneath which the panel is adapted to slide, and at its front end the strip is guided through slots in a box-like pressing 19, Fig. 3, fixed to a channel member 15 welded to the panel. To fix the panel in any position a bar 22 is moved rearwardly, on rotation of a handle 23, and rocks a cam 20 against the strip 17 to grip the strip between the cam and the pressing 19. The cam may be replaced by a tooth or pawl adapted to be forced, against the action of a spring, into engagement with teeth or serrations in the strip 17. When the panel is in the closed position, locking movement of the handle may also bring the rear edge of the panel into a position flush with the front edge of the canopy 12. For this purpose a bent arm 25, Fig. 5, secured to the bar 22 is provided with slotted lugs 26 engaging a cranked part 27 of a transversely-extending rod 28 rotatable in the channel 15 and, adjacent its ends, the rod carries lugs or plates 2, Fig. 2, which overlie abutments 30 in the side channel guides of the roof when the panel is in the closed position. On locking movement of the handle, the arm 25 rocks the rod 28 and the lugs 29 are forced against the abutments 30 to lift the rear end of the panel into the position flush with the canopy, the small vertical movement being permitted by the flexibility of the strip 17 and by a suitable arrangement of the side panel guides. Alternatively, the panel may engage ramps &c. to lift it into its flush position independently of the locking mechanism, as described in Specification 405,413. The panel may be guided by runners sliding in rain-water channels or by sliders co-operating with flanged guides in the channels.

Title: Improvements relating to signal amplifiers
IPC: H03K5/02
Filed: 1965-01-22
Abstract: 1,070,672. Tape stores; electric analogue calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 22, 1965 [Feb. 5, 1964], No. 2853/65. Headings G4C and G4G. [Also in Division H3] Binary data on magnetic tape are sensed by means of a peak-detector as in Specification 857,313 followed by an integrator and Schmitt trigger as in Specification 875,694, the input signal to the peak-detector having been passed through an amplifier whose gain decreases in steps as the input signal increases in instantaneous magnitude above a selected noiserejecting threshold, so that impulsive signals above the normal level drive the amplifying transistor into saturation and thus produce a small integrated signal. In Fig. 2 the signal from the reproducing head (after passing through a switch and linear amplifier, not shown) is applied to the base of transistor 20 which is normally biased non-conducting by the voltage at 24. Positive excursions of the signal have no effect but negative excursions appear amplified and inverted at the collector 23 if they are large enough to overcome the bias. The emitter is normally biased to + 6 V. through diode 40, but when the signal increases sufficiently this diode will cut off and bring in resistors 37 and 38 as emitter loads to reduce the gain. At a further signal level, diode 46 will conduct and add resistor 47 in parallel with the existing collector loads 43, 44 to reduce the gain still further. In addition, diodes 30 and 31 clip excessive peaks. The input sine wave is thus converted to a rounded half-cycle which is passed via emitter follower 14 to the peakdetector and integrator 15. Transistors 58 and 59 operate in the same way as the circuit of Specification 857,313, the positive input signal turning off transistor 59 and turning on 58 to produce a negative-going signal at the base of transistor 73. This signal is limited by diode 74 but is sufficient to turn 73 off and allow integrating capacitor 83 to charge through the emitter follower 82 and operate the Schmitt trigger 91 unless gated off by a signal on the transistor 88. The output of the Schmitt trigger is sharpened by inductors 116, 117 and ringing circuit 118, 119 to produce steep pulses at the leading and trailing edges of the trigger pulse. The negative pulse, which corresponds in time to the peak of the data pulse, gives an output at 128. The invention can be applied to the " non-return to zero " type of recording by adding a mixer (as in Specification 888,692) before the variable-gain amplifier 13.

Filed: 1973-01-19
Abstract: 1374377 Radio signalling MOTOROLA Inc 19 Jan 1973 [7 Feb 1972] 2905/73 Heading H4L In a paging system whose signals contain an address portion followed by an audio information portion, the address portion of each signal is arranged to overlap the information portion of the preceding signal in order to avoid time wastage.  The address portions contain two tones preselected by switches 24, 25 from oscillators 23 in the range 65Hz to 250Hz, to which the audio outputs of the paged receivers 17 are made unresponsive. Initial closure of a pressto-talk switch 11 applies a positive potential A at 30 to the first of two monostables 49, 65. These operate in turn to open successively gates 26, 27 which supply one tone and then the other to the transmitter. The same initial closure of switch 11 also applies earth potential to a diode 31 in a control circuit 13 to energize relay 32 and turn on a tape recorder 14. Voice signals at 12 are recorded, and then reproduced after a delay equal to the duration of the twotone address signal, and applied to the transmitter. When the voice input ends, switch 11 is released, and a delay circuit 18 holds the tape recorder operative for at least long enough to complete transmission of the recorded message. If a new address has been set up by 24, 25 during the recording time, switch 11 may be immediately re-operated to permit the new voice signal to be recorded; and the new address tones will be gated by 26, 27 to the transmitter, concurrently with the end of the delayed, previous voice signal.

Title: Improvements in or relating to the production of the p-chlorophenyl cyanamide salt of isopropyl guanidine
IPC: C07C277/08
Filed: 1949-02-03
Abstract: The p-chlorophenyl cyanamide salt of isopropyl guanidine is made by reacting the cyanamide with isopropyl guanidine or a salt thereof at 0 DEG  to 35 DEG  C., preferably in an aqueous medium.  Molar equivalent quantities of reactants are preferably used and when an isopropyl guanidine salt is used, the sulphate, hydrochloride and nitrate are specified, a stoichiometric amount of caustic alkali may be present.  The desired salt separates from saturated solutions of alkali metal salts and the reaction is either effected to provide such solutions as final reaction mixtures or adjustments are made when reaction is over.  Conventional methods of separation may also be used.  The salt isomerizes on heating to N1-p-chlorophenyl-N5 - isopropyl - biguanide (see Specification 665,680).  In examples: (1) and (2) isopropyl guanidine sulphate is reacted with caustic soda and quantities of p-chlorophenyl cyanamide added in aqueous dispersion until the reaction mixture is neutral when the required product is isolated and in (3) sodium is dissolved in anhydrous methanol, dry isopropyl guanidine sulphate and p-chlorophenyl cyanamide added and the required product isolated from sodium sulphate.  The Specification as open under Sect. 91 relates generally to guanidine salts made by reacting a substituted cyanamide with a substituted guanidine at moderate temperatures.  This subject-matter does not appear in the Specification as accepted.

Abstract: 253,029. Automatic Scale Co., Ltd., and Griffiths, A. V. Feb. 4, 1926. Automatic-feed weighers.-In an automatic weighing-apparatus of the kind wherein the main and dribble feeds are controlled by two mechanically-operated slides the main feed being admitted to the weigh hopper during a constant time period, a number of cam-like members mounted upon, an horizontal intermittentlyrotatable shaft are provided for effecting the ppening and closing of the main feed, the locking of the weighbeam, the opening of the discharge door, and the disengagement of the intermittently - rotatable shaft from the power source. Assuming the weigh hopper 10 to have received its full charge and the dribble feed valve 25 to have closed its feed aperture 9<b>, a leaf spring, pressing upon a cam on an horizontal cam shatt 22, gives the shaft a slight rotation and thus permits a clutch 57, 58 to engage and to couple the shaft to a driving pulley 55. During the subsequent rotation of the shaft the various cams thereon effect the following operations, viz., (1) allow a spring-pressed lever 16 to trip a catch 15b and thus open the discharge gate 10<a> of the weigh hopper, the discharge gate afterwards closing under the influence of a counterweight, (2) draw back the main feed slide 24 to open the main supply aperture 9<a>, a projection 24a on the main feed slide at the same time covering the dribble aperture 9<b> and carrying back the dribble slide 25 into the open position shown in Fig. 5 where it is retained by a catch 34, (3) press down a lever 43 to clamp the weigh beam 11 temporarily between stops 45', 46 during the main feed, (4) return the main feed slide to the closed position after a definite time interval, consequently removing the projection 24a from the dribble aperture 9<b> and permitting the dribble feed to bring the weigh beam to equilibrium. In the equilibrium position, electrical contacts 38, 39 close a circuit and energize an electromagnet 36 which releases the catch 34 and allows the dribble slide 25 to cut off the feed under the influence of a spring. The shaft 22 is brought to rest by a pin 32 on a disc 21 abutting against a stop 31 on a dribble slide 25, the clutch 57, 58 being simultaneously disengaged by contact of a pin 58<b> with a projection on the frame. The quantity of material passing to the weigh hopper during the main feed may be regulated by a plate adjustable across the feed opening. Agitators 47 are rotated within the feed hopper by chain and sprocket gearing.
