Title: Heating food trays in mobile serving unit
Inventor: SEYER REINHARD DIPL ING
IPC: A47J27/62
Filed: 1997-05-26
Abstract: The food trolley, typically for serving warm food in aircraft, contains a number of food trays, some of which require pre-heating to a suitable temperature and the induction heating components. The heating cycle is firstly short and powerful, followed by a longer period at lower energy level and a similar shorter period.

A generator (3) and inductive coupling primary coil (2) are installed within the aircraft, or vehicle, panelling and coupled to a secondary coil (1) in the food trolley for pre-heating of the hot food trays through inductive coils (5) positioned beneath the relevant trays. An initial heating phase of about 200 W per tray at 25-50 kH is applied for about 2 minutes to bring the food to a high temperature without risk of damage to the food or the trays. This is followed by a longer period of reduced power during which the food is further heated without drying out. A third short higher power phase is the applied to bring the food to the desired temperature.

Title: Piezoelectric acceleration sensor e.g. for vehicle airbag
Inventor: OGIURA MITSUGU
IPC: B60R21/16
Filed: 1997-08-13
Abstract: An acceleration sensor (21) has a piezoelectric element (22) consisting of at least three layers (25-30). These are held in a bearer (22,23) of ceramic or other insulant and form a laminate (70) by being sandwiched between the facing ends of multiple first electrodes (31,33,35), running from the second end (72) to the first (71) and second electrodes (32,34,36,37) running in the opposite directions, so that the electrodes partially overlap across the piezoelectric layers. The layers are polarised with both positive and negative loadings as that they deform together with the electrodes whenever the piezoelectric element receives a jolt (73) from acceleration. The use of this laminated system ensures higher loading sensitivity and also greater static capacity.

Title: Brake control system for trams with four-circuit brakes
Inventor: FREITAG RAINER
IPC: B60T8/34
Filed: 1997-09-30
Abstract: A brake force control system for a tram with four-circuit brakes has the brake force at each wheel individually adjustable.

The brake system is designed so that by using one front brake (11,12) and the diagonally opposite rear brake (13,14), the brake force in total corresponds to the vehicle weight multiplied by the maximum amount of the adhesion/traction coefficient exploitable between the track and the wheels.  The adjusters are designed for the normal force distribution. The vehicle weight is supported on one of the front wheels and the diagonally opposite rear wheel, apart from a very small fraction of the same amounting to a few percentage of the wheel loads, approximately symmetrically distributed in the static case.
