Title: Beverage dispenser
IPC: B67D1/00
Filed: 1970-11-24
Abstract: 1329427 Beverage dispenser JET SPRAY COOLER Inc 24 Nov 1970 [23 Dec 19691 55846/70 Heading A4T A beverage dispenser in which water is mixed in fixed proportion with syrup to form e.g. hot chocolate, has a syrup circuit in which a predetermined volume of syrup from tank 30, Fig.2, is drawn past check valve 40 during the down stroke of reciprocating piston 46 driven, via cam 52 controlling the electrical timing circuitry, by motor 54, and passed on the up stroke via pipe 58, syrup reserve cylinder and water control assembly 22, pipe 60, check valve 62 and mixer 20, 136 to the outlet. Water at 102, Fig. 3, passes via solenoid valve 104, assembly 22, water heater 100 with expansion chamber 110 and pipe 112 to the mixer 20 and outlet. One of two different volumes of beverage may be dispensed. By depressing and turning rod 70, Fig.4, to engage rings 74 on flange face 82, the rod end 78 holds piston 80 to one end of a cylinder 64 in assembly 22 whereby the whole volume of syrup displaced by piston 46 passes through the cylinder end to the outlet. The depressed rod 70 also opens valve 124 whereby water from solenoid valve 104 passes through an adjustable flow control 128 and passage 118, 120 to the outlet and also through a flow control 129 at 122 and valve 124 to the passage to give a large amount of water for mixing with the maximum amount of syrup. For a smaller drink, rod 70 is released to free piston 66 which is displaced by the syrup so that a smaller volume is discharged to the outlet, a correspondingly smaller volume of water also being discharged due to valve 124 closing. The syrup remaining in cylinder 64 is withdrawn on the downstroke of piston 46. Tank 30 may contain cleaning solution for the dispenser and hot water only may be dispensed. If tank 30 is filled with cleaning fluid, motor 138 driving mixing impellor 136 will pass the fluid through the mixing chamber.

Title: Speech Analysing Apparatus.
IPC: G10L19/02
Filed: 1967-12-20
Abstract: 1,154,129. Speech recognition. INTERNATIONAL BUSINESS MACHINES CORP. 20 Dec., 1967 [29 Dec., 1966], No. 57991/67. Heading G4R. In speech analysing apparatus, harmonics and the fundamental are detected, detection of the latter controlling means providing signals indicating the time of occurrence of each harmonic. A speech waveform is fed to a pre-amplifier PA having automatic gain control 26, the high, middle (viz. 250-3000 c/s.) and low frequencies being routed to a fricative selector FS, harmonic locator HL and envelope peak detector EPD respectively. In the ease of voiced sound, the detector EPD (which responds to the fundamental) starts a scan ring SCR and a time base ring TBR, after delays. The scan ring SCR distributes the pulses from the harmonic locator HL (presence of a particular harmonic being indicated by presence of a pulse at a corresponding time) to integrating pulse shapers (having a threshold) IPS2-IPS8, the digital outputs from which are set into rows 2-8 of a storage matrix SM, at column positions successively selected by the time base ring TBR. On the other hand, in the case of fricative sound, an integrating pulse shaper IPS 1, fed from the fricative selector FS, starts the time base ring TBR, after a delay, to set successive values of the output of IPS1 into row 1 of the storage matrix SM. The harmonic locator HL consists of a peak detector feeding a univibrator (to produce standard pulses). The delays in activation of the rings are to prevent a pulse from the harmonic locator HL representing the fundamental from being used.

Title: Saw-tooth generator
IPC: H03K4/502
Filed: 1973-12-14
Abstract: 1430397 Saw-tooth wave generators INTERNATIONAL STANDARD ELECTRIC CORP 14 Dec 1973 [21 Dec 1972] 58010/73 Heading H3T A saw-tooth wave generator comprises a constant current source, shown as a current mirror T1, T2, connected to charge a capacitor C via a transistor T 3  of one conductivity type, a second transistor T4 connected in commonemitter configuration with T3, a third transistor T5 of the other conductivity type connected across the capacitor and a fourth transistor T6, also of the other conductivity type, connected across a portion of a potential divider R3, R4, R5 across the supply, the collector of T4 being connected to the bases of T5 and T6. In operation the capacitor-C is charged from the current source until it raises the base voltage of T3 above that of T4 whereupon the current is diverted to T4. This renders T5 conducting to discharge the capacitor and causes T6 to lower the bias voltage at the base of T4. The capacitor discharge is arrested at this value and the circuit reverts to start a new charging cycle. The generator, which is suitable for a television line time-base, may be made in integral form, transistors T1, T2 and T3 being of lateral type.
